A unified interface for interacting with LLM providers like Anthropic, AWS Bedrock, and Google Vertex. It features a resilient request executor that manages retries, rate limits, and errors to ensure reliability across different backends. The system also includes modules for session state synchronization, file asset management, and deep observability to track usage, prompt caching efficiency, and user entitlements.
