Anthropic Provider Integration
Relevant source files
The following files were used as context for generating this wiki page:
The Anthropic Provider Integration enables the evaluation platform to communicate with Anthropic's Claude models. This module handles the translation of internal evaluation requests into Anthropic-specific API calls and processes the resulting text or structured data.
Architecture and Design
The integration follows a provider-based architecture where the AnthropicProvider class implements the abstract interface defined in the base provider. This ensures consistency across different Large Language Model (LLM) backends.
The diagram shows the class hierarchy where the Anthropic implementation inherits from the base provider interface.

Message Formatting and API Interaction
The module converts standard prompt formats into the specific message structure required by the Anthropic Messages API. It supports system prompts and a list of user/assistant messages.
Request Flow
- The system receives an evaluation task.
- The
AnthropicProviderformats the input into amessageslist. - The client sends a POST request to the Anthropic API endpoint.
- The provider extracts the text content from the response object.
The sequence diagram illustrates the flow of data from the evaluation engine through the provider to the external API.

Configuration Parameters
The integration supports several configuration options to control model behavior and API communication.
| Parameter | Type | Description |
|---|---|---|
model | string | The specific Anthropic model identifier (e.g., claude-3-opus-20240229). |
max_tokens | integer | The maximum number of tokens to generate in the response. |
temperature | float | Controls randomness; higher values increase variety. |
api_key | string | The authentication token for Anthropic API access. |

Error Handling and Validation
The provider implements specific logic to handle common API issues:
- Rate Limiting: The system catches 429 errors and applies backoff strategies.
- Input Validation: Before sending requests, the provider ensures the system prompt and message history conform to Anthropic's requirements.
- Token Limits: The provider tracks token usage to prevent exceeding context window limits.

Conclusion
The Anthropic Provider Integration provides a robust bridge between the eval-platform and Claude models. By standardizing the interface through the base provider class, the platform allows for seamless switching between Anthropic and other LLM providers while maintaining specific optimizations for Anthropic's API structure.
