Include latest LiteLLM features, security considerations, and integration patterns for 2025. - -**Response:** - -Implementing a **LiteLLM proxy server** with advanced routing, transformation, and observability requires a modular, secure, and extensible architecture. Below is a comprehensive guide tailored to your project context, incorporating the latest LiteLLM features, best practices for 2025, and actionable integration patterns. - ---- - -## 1. Project Initialization and Environment Setup - -**Best Practices:** -- **Python Environment:** Use Python 3.10+ for compatibility with the latest LiteLLM releases[1][5]. -- **Dependency Management:** Pin LiteLLM to the latest stable version (e.g., `>=2.5.0`), and include `typing-extensions`, `PyYAML`, `pydantic`, and testing/linting tools (`pytest`, `ruff`, `black`, `mypy`). -- **Version Control:** Initialize a Git repository with a `.gitignore` covering Python, VSCode, and environment files. -- **Pre-commit Hooks:** Set up `pre-commit` for linting and type checking to enforce code quality. -- **Documentation:** Document setup steps in `README.md` for reproducibility. - -**Example:** -```bash -python -m venv .venv -source .venv/bin/activate -pip install "litellm>=2.5.0" typing-extensions pyyaml "pydantic>=2.0" pytest ruff black mypy -``` - ---- - -## 2. Configuration Loader: YAML + Environment Overrides - -**Key Patterns:** -- **YAML Config:** Store model lists, routing, and transformation settings in a YAML file for clarity and versioning[1][3][4]. -- **Environment Overrides:** Allow environment variables to override YAML for secrets and deployment flexibility. -- **Schema Validation:** Use `pydantic` to validate config structure and types, ensuring early error detection. - -**Example Loader Skeleton:** -```python -import os -import yaml -from pydantic import BaseModel, ValidationError - -class ProxyConfig(BaseModel): - model_list: list - router_settings: dict = {} - # ... other fields - -def load_config(path: str) -> ProxyConfig: - with open(path) as f: - data = yaml.safe_load(f) - # Apply environment overrides here - # Example: data['context_threshold'] = os.getenv('CCPROXY_CONTEXT_THRESHOLD', data.get('context_threshold')) - return ProxyConfig(**data) -``` - -**Testing:** Unit test with valid/invalid YAML, missing fields, and env overrides. - ---- - -## 3. Custom Routing Hooks with LiteLLM - -**Latest LiteLLM Features:** -- **Custom Hooks:** Use `async_pre_call_hook` for request interception and routing logic[1][3]. -- **Routing Strategies:** Support for custom routing strategies (e.g., least-busy, round-robin) via `router_settings` in config[3]. -- **Extensibility:** Design routing logic to be easily extensible for new labels or rules. - -**Implementation:** -- **Routing Module:** Implement as `ccproxy_router.py`, mapping request context (token count, model, tools, etc.) to routing labels. -- **Fallbacks:** If a label is not configured, default to a base provider (e.g., Anthropic). -- **Logging:** Log all routing decisions for observability. - -**Example Hook:** -```python -from litellm.proxy.hooks import async_pre_call_hook - -class CCProxyRouter: - async def async_pre_call_hook(self, request, context): - # Inspect request, apply routing logic - label = self.route_request(request) - # Modify request or context as needed - return request, context -``` - ---- - -## 4. Model Transformation Pipelines - -**Best Practices:** -- **Composable Pipelines:** Allow chaining of multiple transformations (request/response rewriting, augmentation, etc.). -- **Plugin Interface:** Enable users to register custom transformations via config or plugin discovery. -- **Order Preservation:** Ensure transformations are applied in the configured order. - -**Implementation:** -- **Pipeline Design:** Use a list of callables or classes, each implementing a `transform(request, context)` method. -- **Registration:** Support dynamic registration via config or entry points. - -**Example Pipeline:** -```python -class TransformationPipeline: - def __init__(self, transforms): - self.transforms = transforms - - async def apply(self, request, context): - for transform in self.transforms: - request, context = await transform(request, context) - return request, context -``` - ---- - -## 5. Advanced Observability and Metrics - -**Latest Features:** -- **Built-in Observability:** LiteLLM supports logging hooks and metrics collection (`log_transformations`, `metrics_enabled`)[3][4]. -- **External Integration:** Integrate with Prometheus or OpenTelemetry for external monitoring if supported[2]. -- **Slow Event Detection:** Track and log slow transformation events with configurable thresholds. - -**Implementation:** -- **Logging:** Log all routing, transformation, and error events with context. -- **Metrics:** Track latency, error rates, and transformation counts. -- **Integration:** Expose metrics endpoints or push to external systems as needed. - -**Example:** -```yaml -general_settings: - metrics_enabled: true - log_transformations: true -``` - ---- - -## 6. Security and API Key Management - -**Best Practices:** -- **API Key Validation:** Use LiteLLM's `UserAPIKeyAuth` for authenticating requests[3]. -- **Secret Management:** Store API keys and sensitive config in environment variables or secure vaults (e.g., HashiCorp Vault, AWS Secrets Manager)[2]. -- **Transport Security:** Enforce HTTPS for all external API calls and proxy endpoints. Use SSL certificates via `ssl_keyfile_path` and `ssl_certfile_path` in deployment[2]. -- **Audit Logging:** Log authentication events and access attempts for auditability. - -**Example Secure Config:** -```yaml -general_settings: - master_key: ${LITELLM_MASTER_KEY} -``` -**Deployment:** -```bash -docker run ghcr.io/berriai/litellm:main-stable \ - --ssl_keyfile_path /path/to/keyfile.key \ - --ssl_certfile_path /path/to/certfile.crt -``` - ---- - -## 7. Integration Patterns and Deployment - -**Patterns:** -- **OpenAI-Compatible API:** LiteLLM proxy exposes an OpenAI-compatible endpoint, simplifying integration with existing clients[5]. -- **Multi-Provider Support:** Configure multiple providers (OpenAI, Azure, Ollama, vLLM, etc.) in `model_list`[1][4]. -- **Dockerization:** Use official LiteLLM Docker images for deployment. Support custom entrypoints and config mounting[2]. -- **12-Factor Compliance:** All config should be overridable via environment variables for cloud-native deployments. - -**Example Config:** -```yaml -model_list: - - model_name: gpt-3.5-turbo - litellm_params: - model: gpt-3.5-turbo - api_key: ${OPENAI_API_KEY} - - model_name: ollama/llama3 - litellm_params: - model: ollama/llama3 -``` - ---- - -## 8. Testing and Validation - -**Best Practices:** -- **Unit and Integration Tests:** Use `pytest` for >90% coverage, mocking external APIs and LiteLLM interfaces. -- **Edge Cases:** Test all routing, transformation, and error scenarios. -- **CI Integration:** Run tests and coverage checks on push/PR via GitHub Actions or similar. - ---- - -## 9. Documentation and Examples - -**Recommendations:** -- **Comprehensive Docs:** Document all config fields, environment variables, and extension APIs. -- **Usage Examples:** Provide real-world scenarios for routing, transformation, and observability. -- **Troubleshooting:** Include common issues and solutions. - ---- - -## 10. Edge Cases and Pitfalls - -- **Transformation Failures:** Ensure robust error handling in transformation pipelines to avoid request loss. -- **Routing Loops:** Guard against recursive or conflicting routing rules. -- **Secret Leakage:** Never log sensitive data; redact secrets in logs and error messages. -- **Performance:** Monitor transformation latency and optimize slow steps. - ---- - -## Summary Table: Key Features and Best Practices - -| Area | Best Practice / Feature | LiteLLM Support (2025) | -|---------------------|----------------------------------------------------------------------------------------|------------------------| -| Config Management | YAML + env overrides, pydantic validation | Yes | -| Routing | Custom async hooks, extensible logic, fallback support | Yes | -| Transformation | Chained, composable pipelines, plugin registration | Yes | -| Observability | Built-in logging/metrics, Prometheus/OpenTelemetry integration, slow event detection | Yes | -| Security | API key auth, env/vault secrets, HTTPS, audit logging | Yes | -| Deployment | Docker, OpenAI-compatible API, multi-provider, 12-factor compliance | Yes | -| Testing | Pytest, coverage, CI/CD integration | Yes | -| Documentation | Full config/API docs, usage examples, troubleshooting | Yes | - ---- - -**Actionable Next Steps for Your Project:** -- Implement the configuration loader and routing logic as described above, referencing your `ccproxy_router.py` and config schema. -- Design the transformation pipeline for composability and register via config. -- Leverage LiteLLM’s observability and security features, integrating with your preferred monitoring and secret management tools. -- Ensure all modules are thoroughly tested and documented, following the outlined best practices. - -If you need code templates or deeper dives into any specific area (e.g., transformation API, advanced routing examples, or observability integration), please specify, and I can provide detailed implementation guidance. - - ---- - -*Generated by Task Master Research Command* -*Timestamp: 2025-07-29T22:01:47.206Z* diff --git a/.taskmaster/reports/task-complexity-report.json b/.taskmaster/reports/task-complexity-report.json deleted file mode 100644 index 1166b2cf..00000000 --- a/.taskmaster/reports/task-complexity-report.json +++ /dev/null @@ -1,77 +0,0 @@ -{ - "meta": { - "generatedAt": "2025-07-30T01:24:06.776Z", - "tasksAnalyzed": 8, - "totalTasks": 10, - "analysisCount": 8, - "thresholdScore": 5, - "projectName": "ccproxy", - "usedResearch": false - }, - "complexityAnalysis": [ - { - "taskId": 3, - "taskTitle": "Develop RequestClassifier Module", - "complexityScore": 8, - "recommendedSubtasks": 6, - "expansionPrompt": "Expand this task by adding any missing implementation, refactoring, or documentation subtasks needed to fully deliver a robust, extensible RequestClassifier.

Changing only the user message enables asking various questions about the book using the cached content, which can lead to faster responses and increased efficiency. + +--- + +## How prompt caching works + +When you send a request with prompt caching enabled: + +1. The system checks if a prompt prefix, up to a specified cache breakpoint, is already cached from a recent query. +2. If found, it uses the cached version, reducing processing time and costs. +3. Otherwise, it processes the full prompt and caches the prefix once the response begins. + +This is especially useful for: + +- Prompts with many examples +- Large amounts of context or background information +- Repetitive tasks with consistent instructions +- Long multi-turn conversations + +By default, the cache has a 5-minute lifetime. The cache is refreshed for no additional cost each time the cached content is used. + +For durations longer than 5 minutes, a 1-hour cache duration is available. This feature is currently in beta. + +For more information, see [1-hour cache duration](https://docs.anthropic.com/en/docs/build-with-claude/prompt-caching#1-hour-cache-duration). + +**Prompt caching caches the full prefix** + +Prompt caching references the entire prompt - `tools`, `system`, and `messages` (in that order) up to and including the block designated with `cache_control`. + +--- + +## Pricing + +Prompt caching introduces a new pricing structure. The table below shows the price per million tokens for each supported model: + +| Model | Base Input Tokens | 5m Cache Writes | 1h Cache Writes | Cache Hits & Refreshes | Output Tokens | +| :---------------- | :---------------- | :-------------- | :-------------- | :--------------------- | :------------ | +| Claude Opus 4.1 | $15 / MTok | $18.75 / MTok | $30 / MTok | $1.50 / MTok | $75 / MTok | +| Claude Opus 4 | $15 / MTok | $18.75 / MTok | $30 / MTok | $1.50 / MTok | $75 / MTok | +| Claude Sonnet 4 | $3 / MTok | $3.75 / MTok | $6 / MTok | $0.30 / MTok | $15 / MTok | +| Claude Sonnet 3.7 | $3 / MTok | $3.75 / MTok | $6 / MTok | $0.30 / MTok | $15 / MTok | +| Claude Sonnet 3.5 | $3 / MTok | $3.75 / MTok | $6 / MTok | $0.30 / MTok | $15 / MTok | +| Claude Haiku 3.5 | $0.80 / MTok | $1 / MTok | $1.6 / MTok | $0.08 / MTok | $4 / MTok | +| Claude Opus 3 | $15 / MTok | $18.75 / MTok | $30 / MTok | $1.50 / MTok | $75 / MTok | +| Claude Haiku 3 | $0.25 / MTok | $0.30 / MTok | $0.50 / MTok | $0.03 / MTok | $1.25 / MTok | + +Note: + +- 5-minute cache write tokens are 1.25 times the base input tokens price +- 1-hour cache write tokens are 2 times the base input tokens price +- Cache read tokens are 0.1 times the base input tokens price +- Regular input and output tokens are priced at standard rates + +--- + +## How to implement prompt caching + +### Supported models + +Prompt caching is currently supported on: + +- Claude Opus 4.1 +- Claude Opus 4 +- Claude Sonnet 4 +- Claude Sonnet 3.7 +- Claude Sonnet 3.5 +- Claude Haiku 3.5 +- Claude Haiku 3 +- Claude Opus 3 + +### Structuring your prompt + +Place static content (tool definitions, system instructions, context, examples) at the beginning of your prompt. Mark the end of the reusable content for caching using the `cache_control` parameter. + +Cache prefixes are created in the following order: `tools`, `system`, then `messages`. This order forms a hierarchy where each level builds upon the previous ones. + +#### How automatic prefix checking works + +A single cache breakpoint at the end of static content is often sufficient, as the system automatically finds the longest matching prefix. Here’s how it works: + +- When you add a `cache_control` breakpoint, the system automatically checks for cache hits at all previous content block boundaries (up to approximately 20 blocks before your explicit breakpoint) +- If any of these previous positions match cached content from earlier requests, the system uses the longest matching prefix +- This means you don’t need multiple breakpoints just to enable caching - one at the end is sufficient + +#### When to use multiple breakpoints + +You can define up to 4 cache breakpoints if you want to: + +- Cache different sections that change at different frequencies (e.g., tools rarely change, but context updates daily) +- Have more control over exactly what gets cached +- Ensure caching for content more than 20 blocks before your final breakpoint + +**Important limitation**: The automatic prefix checking only looks back approximately 20 content blocks from each explicit breakpoint. If your prompt has more than 20 content blocks before your cache breakpoint, content earlier than that won’t be checked for cache hits unless you add additional breakpoints. + +### Cache limitations + +The minimum cacheable prompt length is: + +- 1024 tokens for Claude Opus 4, Claude Sonnet 4, Claude Sonnet 3.7, Claude Sonnet 3.5 and Claude Opus 3 +- 2048 tokens for Claude Haiku 3.5 and Claude Haiku 3 + +Shorter prompts cannot be cached, even if marked with `cache_control`. Any requests to cache fewer than this number of tokens will be processed without caching. To see if a prompt was cached, see the response usage [fields](https://docs.anthropic.com/en/docs/build-with-claude/prompt-caching#tracking-cache-performance). + +For concurrent requests, note that a cache entry only becomes available after the first response begins. If you need cache hits for parallel requests, wait for the first response before sending subsequent requests. + +### Understanding cache breakpoint costs + +Cache breakpoints do not add cost. Charges apply for: + +- **Cache writes**: When new content is written to the cache (25% more than base input tokens for 5-minute TTL) +- **Cache reads**: When cached content is used (10% of base input token price) +- **Regular input tokens**: For any uncached content + +Adding more `cache_control` breakpoints doesn’t increase your costs - you still pay the same amount based on what content is actually cached and read. The breakpoints simply give you control over what sections can be cached independently. + +### What can be cached + +Most blocks in the request can be designated for caching with `cache_control`. This includes: + +- Tools: Tool definitions in the `tools` array +- System messages: Content blocks in the `system` array +- Text messages: Content blocks in the `messages.content` array, for both user and assistant turns +- Images & Documents: Content blocks in the `messages.content` array, in user turns +- Tool use and tool results: Content blocks in the `messages.content` array, in both user and assistant turns + +Each of these elements can be marked with `cache_control` to enable caching for that portion of the request. + +### What cannot be cached + +While most request blocks can be cached, there are some exceptions: + +- Thinking blocks cannot be cached directly with `cache_control`. However, thinking blocks CAN be cached alongside other content when they appear in previous assistant turns. When cached this way, they DO count as input tokens when read from cache. + +- Sub-content blocks (like [citations](https://docs.anthropic.com/en/docs/build-with-claude/citations)) themselves cannot be cached directly. Instead, cache the top-level block. + +For citations, top-level document content blocks serving as source material can be cached. This enables prompt caching with citations by caching the referenced documents. + +- Empty text blocks cannot be cached. + +### What invalidates the cache + +Modifications to cached content can invalidate some or all of the cache. + +As described in [Structuring your prompt](https://docs.anthropic.com/en/docs/build-with-claude/prompt-caching#structuring-your-prompt), the cache follows the hierarchy: `tools` → `system` → `messages`. Changes at each level invalidate that level and all subsequent levels. + +The following table shows which parts of the cache are invalidated by different types of changes. ✘ indicates that the cache is invalidated, while ✓ indicates that the cache remains valid. + +| What changes | Tools cache | System cache | Messages cache | Impact | +| :-------------------------------------------------------- | :---------: | :----------: | :------------: | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | +| **Tool definitions** | ✘ | ✘ | ✘ | Modifying tool definitions (names, descriptions, parameters) invalidates the entire cache | +| **Web search toggle** | ✓ | ✘ | ✘ | Enabling/disabling web search modifies the system prompt | +| **Citations toggle** | ✓ | ✘ | ✘ | Enabling/disabling citations modifies the system prompt | +| **Tool choice** | ✓ | ✓ | ✘ | Changes to `tool_choice` parameter only affect message blocks | +| **Images** | ✓ | ✓ | ✘ | Adding/removing images anywhere in the prompt affects message blocks | +| **Thinking parameters** | ✓ | ✓ | ✘ | Changes to extended thinking settings (enable/disable, budget) affect message blocks | +| **Non-tool results passed to extended thinking requests** | ✓ | ✓ | ✘ | When non-tool results are passed in requests while extended thinking is enabled, all previously-cached thinking blocks are stripped from context, and any messages in context that follow those thinking blocks are removed from the cache.

Prompt caching supports including numerous examples (e.g., 20+) to refine responses. +- Agentic tool use: Supports scenarios involving multiple tool calls and iterative code changes, where each step typically requires a new API call. +- Longform content analysis: Supports embedding entire documents (e.g., books, papers, documentation, podcast transcripts) into the prompt for user queries. + +### Troubleshooting common issues + +If experiencing unexpected behavior: + +- Ensure cached sections are identical and marked with cache_control in the same locations across calls +- Check that calls are made within the cache lifetime (5 minutes by default) +- Verify that `tool_choice` and image usage remain consistent between calls +- Validate that you are caching at least the minimum number of tokens +- The system automatically checks for cache hits at previous content block boundaries (up to ~20 blocks before your breakpoint). For prompts with more than 20 content blocks, you may need additional `cache_control` parameters earlier in the prompt to ensure all content can be cached + +Changes to `tool_choice` or the presence/absence of images anywhere in the prompt will invalidate the cache, requiring a new cache entry to be created. For more details on cache invalidation, see [What invalidates the cache](https://docs.anthropic.com/en/docs/build-with-claude/prompt-caching#what-invalidates-the-cache). + +### Caching with thinking blocks + +When using [extended thinking](https://docs.anthropic.com/en/docs/build-with-claude/extended-thinking) with prompt caching, thinking blocks have special behavior: + +**Automatic caching alongside other content**: While thinking blocks cannot be explicitly marked with `cache_control`, they get cached as part of the request content when you make subsequent API calls with tool results. This commonly happens during tool use when you pass thinking blocks back to continue the conversation. + +**Input token counting**: When thinking blocks are read from cache, they count as input tokens in your usage metrics. This is important for cost calculation and token budgeting. + +**Cache invalidation patterns**: + +- Cache remains valid when only tool results are provided as user messages +- Cache gets invalidated when non-tool-result user content is added, causing all previous thinking blocks to be stripped +- This caching behavior occurs even without explicit `cache_control` markers + +For more details on cache invalidation, see [What invalidates the cache](https://docs.anthropic.com/en/docs/build-with-claude/prompt-caching#what-invalidates-the-cache). + +**Example with tool use**: + +``` +Request 1: User: "What's the weather in Paris?" +Response: [thinking_block_1] + [tool_use block 1] + +Request 2: +User: ["What's the weather in Paris?"], +Assistant: [thinking_block_1] + [tool_use block 1], +User: [tool_result_1, cache=True] +Response: [thinking_block_2] + [text block 2] +# Request 2 caches its request content (not the response) +# The cache includes: user message, thinking_block_1, tool_use block 1, and tool_result_1 + +Request 3: +User: ["What's the weather in Paris?"], +Assistant: [thinking_block_1] + [tool_use block 1], +User: [tool_result_1, cache=True], +Assistant: [thinking_block_2] + [text block 2], +User: [Text response, cache=True] +# Non-tool-result user block causes all thinking blocks to be ignored +# This request is processed as if thinking blocks were never present +``` + +When a non-tool-result user block is included, it designates a new assistant loop and all previous thinking blocks are removed from context. + +For more detailed information, see the [extended thinking documentation](https://docs.anthropic.com/en/docs/build-with-claude/extended-thinking#understanding-thinking-block-caching-behavior). + +--- + +## Cache storage and sharing + +- **Organization Isolation**: Caches are isolated between organizations. Different organizations never share caches, even if they use identical prompts. + +- **Exact Matching**: Cache hits require 100% identical prompt segments, including all text and images up to and including the block marked with cache control. + +- **Output Token Generation**: Prompt caching has no effect on output token generation. The response you receive will be identical to what you would get if prompt caching was not used. + +--- + +## 1-hour cache duration + +For durations longer than 5 minutes, a 1-hour cache duration is available. This feature is currently in beta. + +To use the extended cache, add `extended-cache-ttl-2025-04-11` as a [beta header](https://docs.anthropic.com/en/api/beta-headers) to your request, and then include `ttl` in the `cache_control` definition like this: + +```json +"cache_control": { + "type": "ephemeral", + "ttl": "5m" | "1h" +} +``` + +The response will include detailed cache information like the following: + +```json +{ + "usage": { + "input_tokens": ..., + "cache_read_input_tokens": ..., + "cache_creation_input_tokens": ..., + "output_tokens": ..., + + "cache_creation": { + "ephemeral_5m_input_tokens": 456, + "ephemeral_1h_input_tokens": 100 + } + } +} +``` + +Note that the current `cache_creation_input_tokens` field equals the sum of the values in the `cache_creation` object. + +### When to use the 1-hour cache + +For prompts used regularly (e.g., system prompts more frequently than every 5 minutes), the 5-minute cache remains suitable as it refreshes without additional charge. + +The 1-hour cache is suitable in the following scenarios: + +- When prompts are likely used less frequently than 5 minutes, but more frequently than every hour. For example, when an agentic side-agent will take longer than 5 minutes, or when storing a long chat conversation with a user and you generally expect that user may not respond in the next 5 minutes. +- When latency is important and follow-up prompts may be sent beyond 5 minutes. +- When improved rate limit utilization is desired, as cache hits are not deducted against your rate limit. + +Both 5-minute and 1-hour caches exhibit similar latency behavior, with typical improvements in time-to-first-token for long documents. + +### Mixing different TTLs + +You can use both 1-hour and 5-minute cache controls in the same request, but with an important constraint: Cache entries with longer TTL must appear before shorter TTLs (i.e., a 1-hour cache entry must appear before any 5-minute cache entries). + +When mixing TTLs, we determine three billing locations in your prompt: + +1. Position `A`: The token count at the highest cache hit (or 0 if no hits). +2. Position `B`: The token count at the highest 1-hour `cache_control` block after `A` (or equals `A` if none exist). +3. Position `C`: The token count at the last `cache_control` block. + +If `B` and/or `C` are larger than `A`, they will necessarily be cache misses, because `A` is the highest cache hit. + +You’ll be charged for: + +1. Cache read tokens for `A`. +2. 1-hour cache write tokens for `(B - A)`. +3. 5-minute cache write tokens for `(C - B)`. + +Here are 3 examples.

These instructions rarely change between requests. + +3. **RAG context cache** (cache breakpoint 3): The knowledge base documents are cached independently, allowing you to update the RAG documents without invalidating the tools or instructions cache. + +4. **Conversation history cache** (cache breakpoint 4): The assistant’s response is marked with `cache_control` to enable incremental caching of the conversation as it progresses. + +This approach allows flexibility: + +- If you only update the final user message, all four cache segments are reused +- If you update the RAG documents but keep the same tools and instructions, the first two cache segments are reused +- If you change the conversation but keep the same tools, instructions, and documents, the first three segments are reused +- Each cache breakpoint can be invalidated independently based on what changes in your application + +For the first request: + +- `input_tokens`: Tokens in the final user message +- `cache_creation_input_tokens`: Tokens in all cached segments (tools + instructions + RAG documents + conversation history) +- `cache_read_input_tokens`: 0 (no cache hits) + +For subsequent requests with only a new user message: + +- `input_tokens`: Tokens in the new user message only +- `cache_creation_input_tokens`: Any new tokens added to conversation history +- `cache_read_input_tokens`: All previously cached tokens (tools + instructions + RAG documents + previous conversation) + +This pattern is useful for: + +- RAG applications with large document contexts +- Agent systems that use multiple tools +- Long-running conversations that need to maintain context +- Applications that need to optimize different parts of the prompt independently + +--- + +## FAQ + +### Do I need multiple cache breakpoints or is one at the end sufficient? + +A single cache breakpoint at the end of static content is often adequate. The system automatically checks for cache hits at all previous content block boundaries (up to 20 blocks before the breakpoint) and uses the longest matching prefix. + +You only need multiple breakpoints if: + +- You have more than 20 content blocks before your desired cache point +- You want to cache sections that update at different frequencies independently +- You need explicit control over what gets cached for cost optimization + +Example: If you have system instructions (rarely change) and RAG context (changes daily), you might use two breakpoints to cache them separately. + +### Do cache breakpoints add extra cost? + +Cache breakpoints do not incur direct costs. Charges apply for: + +- Writing content to cache (25% more than base input tokens for 5-minute TTL) +- Reading from cache (10% of base input token price) +- Regular input tokens for uncached content + +The number of breakpoints doesn’t affect pricing - only the amount of content cached and read matters. + +### What is the cache lifetime? + +The cache’s default minimum lifetime (TTL) is 5 minutes. This lifetime is refreshed each time the cached content is used. + +For durations longer than 5 minutes, a [1-hour cache TTL](https://docs.anthropic.com/en/docs/build-with-claude/prompt-caching#1-hour-cache-duration) is available. + +### How many cache breakpoints can I use? + +You can define up to 4 cache breakpoints (using `cache_control` parameters) in your prompt. + +### Is prompt caching available for all models? + +No, prompt caching is currently only available for Claude Opus 4, Claude Sonnet 4, Claude Sonnet 3.7, Claude Sonnet 3.5, Claude Haiku 3.5, Claude Haiku 3, and Claude Opus 3. + +### How does prompt caching work with extended thinking? + +Cached system prompts and tools will be reused when thinking parameters change. However, thinking changes (enabling/disabling or budget changes) will invalidate previously cached prompt prefixes with messages content. + +For more details on cache invalidation, see [What invalidates the cache](https://docs.anthropic.com/en/docs/build-with-claude/prompt-caching#what-invalidates-the-cache). + +For more on extended thinking, including its interaction with tool use and prompt caching, see the [extended thinking documentation](https://docs.anthropic.com/en/docs/build-with-claude/extended-thinking#extended-thinking-and-prompt-caching). + +### How do I enable prompt caching? + +To enable prompt caching, include at least one `cache_control` breakpoint in your API request. + +### Can I use prompt caching with other API features? + +Yes, prompt caching can be used alongside other API features like tool use and vision capabilities. However, changing whether there are images in a prompt or modifying tool use settings will break the cache. + +For more details on cache invalidation, see [What invalidates the cache](https://docs.anthropic.com/en/docs/build-with-claude/prompt-caching#what-invalidates-the-cache). + +### How does prompt caching affect pricing? + +Prompt caching introduces a new pricing structure where cache writes cost 25% more than base input tokens, while cache hits cost only 10% of the base input token price. + +### Can I manually clear the cache? + +Currently, there’s no way to manually clear the cache. Cached prefixes automatically expire after a minimum of 5 minutes of inactivity. + +### How can I track the effectiveness of my caching strategy? + +You can monitor cache performance using the `cache_creation_input_tokens` and `cache_read_input_tokens` fields in the API response. + +### What can break the cache? + +See [What invalidates the cache](https://docs.anthropic.com/en/docs/build-with-claude/prompt-caching#what-invalidates-the-cache) for more details on cache invalidation, including a list of changes that require creating a new cache entry. + +### How does prompt caching handle privacy and data separation? + +Prompt caching implements privacy and data separation: + +1. Cache keys are generated using a cryptographic hash of the prompts up to the cache control point. This means only requests with identical prompts can access a specific cache. + +2. Caches are organization-specific. Users within the same organization can access the same cache if they use identical prompts, but caches are not shared across different organizations, even for identical prompts. + +3. The caching mechanism maintains the integrity and privacy of each unique conversation or context. + +4. It’s safe to use `cache_control` anywhere in your prompts. For cost efficiency, it’s better to exclude highly variable parts (e.g., user’s arbitrary input) from caching. + +These measures maintain data privacy and security while providing performance benefits. + +### Can I use prompt caching with the Batches API? + +Yes, it is possible to use prompt caching with your [Batches API](https://docs.anthropic.com/en/docs/build-with-claude/batch-processing) requests. However, because asynchronous batch requests can be processed concurrently and in any order, cache hits are provided on a best-effort basis. + +The [1-hour cache](https://docs.anthropic.com/en/docs/build-with-claude/prompt-caching#1-hour-cache-duration) may improve cache hits. A method for its cost-effective use is: + +- Gather a set of message requests that have a shared prefix. +- Send a batch request with just a single request that has this shared prefix and a 1-hour cache block. This will get written to the 1-hour cache. +- As soon as this is complete, submit the rest of the requests. You will have to monitor the job to know when it completes. + +This approach is generally preferred over the 5-minute cache for batch requests that may exceed 5 minutes in completion time. Efforts are underway to further enhance cache hit rates and streamline this process. + +### Why am I seeing the error `AttributeError: 'Beta' object has no attribute 'prompt_caching'` in Python? + +This error typically appears when you have upgraded your SDK or you are using outdated code examples. Prompt caching is now generally available, so you no longer need the beta prefix. Instead of: + +```python +client.beta.prompt_caching.messages.create(...) +``` + +Simply use: + +```python +client.messages.create(...) +``` + +### Why am I seeing 'TypeError: Cannot read properties of undefined (reading 'messages')'? + +This error typically appears when you have upgraded your SDK or you are using outdated code examples.

-This directory contains example custom rules and configurations to help you extend ccproxy. - -## Files - -### custom_rule.py -A comprehensive example showing four different rule patterns: - -1. **PriorityUserRule** - Routes based on user identity and message keywords -2. **TimeBasedRule** - Routes based on time of day -3. **ContentLengthRule** - Routes based on total message length -4. **ModelCapabilityRule** - Routes based on required model features - -### example_ccproxy.yaml -Complete configuration example showing how to use both built-in and custom rules. - -## Creating Your Own Rules - -### Step 1: Create Your Rule Class - -Copy `custom_rule.py` to your project and modify it: - -```python -from typing import Any -from ccproxy.rules import ClassificationRule -from ccproxy.config import CCProxyConfig - -class MyCustomRule(ClassificationRule): - def __init__(self, my_param: str) -> None: - self.my_param = my_param - - def evaluate(self, request: dict[str, Any], config: CCProxyConfig) -> bool: - # Your logic here - return True # Return True to use this rule's label -``` - -### Step 2: Configure in ccproxy.yaml - -Add your rule to the ccproxy configuration: - -```yaml -ccproxy: - rules: - - label: my_model_label # Must match a model_name in config.yaml - rule: myproject.MyCustomRule # Python import path - params: - - my_param: "value" -``` - -### Step 3: Ensure Model Configuration - -Make sure you have a corresponding model in your LiteLLM `config.yaml`: - -```yaml -model_list: - - model_name: my_model_label # Matches the label above - litellm_params: - model: gpt-4 -``` - -## Rule Guidelines - -### Constructor Parameters - -Rules can accept parameters in several formats: - -```yaml -# Single positional argument -params: - - "single_value" - -# Multiple positional arguments -params: - - "first" - - "second" - -# Keyword arguments -params: - - param1: "value1" - param2: "value2" - -# Mixed (multiple dicts merged) -params: - - setting1: true - - setting2: false -``` - -### Request Structure - -The `request` parameter contains the LiteLLM request data: - -```python -{ - "model": "claude-3-5-sonnet", - "messages": [ - {"role": "user", "content": "Hello"} - ], - "metadata": { - "user_email": "user@example.com", - # Other metadata - }, - "tools": [...], # If using function calling - "stream": False, - # Other LiteLLM parameters -} -``` - -### Best Practices - -1. **Type Safety**: Always use proper type hints -2. **Error Handling**: Return `False` on errors rather than raising exceptions -3. **Performance**: Keep evaluation logic fast as it runs on every request -4. **Documentation**: Document your rule's purpose and parameters -5. **Testing**: Include test code to verify your rule works correctly - -## Testing Your Rules - -Run the example to see how rules work: - -```bash -python examples/custom_rule.py -``` - -Or test in your own code: - -```python -from myproject import MyCustomRule - -rule = MyCustomRule("parameter") -test_request = { - "messages": [{"role": "user", "content": "Test"}], - # ... other request data -} - -result = rule.evaluate(test_request, config) -print(f"Rule matched: {result}") -``` - -## Advanced Patterns - -### Accessing LiteLLM Runtime - -If you need to access the LiteLLM proxy runtime: - -```python -from litellm.proxy import proxy_server - -def evaluate(self, request: dict[str, Any], config: CCProxyConfig) -> bool: - if proxy_server and proxy_server.llm_router: - model_list = proxy_server.llm_router.model_list - # Use model configuration data - return False -``` - -### Stateful Rules - -For rules that need to maintain state: - -```python -class RateLimitRule(ClassificationRule): - def __init__(self, requests_per_minute: int) -> None: - self.limit = requests_per_minute - self._request_times: list[float] = [] - - def evaluate(self, request: dict[str, Any], config: CCProxyConfig) -> bool: - import time - current_time = time.time() - # Clean old entries - self._request_times = [ - t for t in self._request_times - if current_time - t < 60 - ] - # Check rate limit - if len(self._request_times) >= self.limit: - return True # Route to rate-limited model - self._request_times.append(current_time) - return False -``` - -## Need Help? - -- See the main project documentation for more details -- Check existing rules in `src/ccproxy/rules.py` for more examples -- Ensure your rule follows the same patterns as the built-in rules diff --git a/examples/anthropic_sdk.py b/examples/anthropic_sdk.py new file mode 100755 index 00000000..ae6b5861 --- /dev/null +++ b/examples/anthropic_sdk.py @@ -0,0 +1,106 @@ +#!/usr/bin/env python3 +"""Example using Anthropic SDK with LiteLLM proxy (credentials config). + +This example demonstrates using the Anthropic SDK pointed at the LiteLLM proxy +WITHOUT requiring an API key variable.
