The Braintrust AI Proxy provides a unified API to access multiple large language models, simplifying integration and reducing costs through automatic caching. It's designed for developers working with various AI providers, offering enhanced observability and a consistent interface.

How It Works

The proxy acts as an intermediary, routing requests to different AI models (OpenAI, Anthropic, LLaMa 2, Mistral, etc.) via a single, standardized API. A key feature is its caching mechanism, which stores responses to identical requests (identified by model, prompt, and a seed parameter) to reduce redundant API calls and associated costs. This approach simplifies code by abstracting away provider-specific API differences.

Quick Start & Requirements

• Usage: Set baseURL to https://api.braintrust.dev/v1/proxy in OpenAI SDKs or use the provided cURL example.
• Dependencies: Requires an API key from a supported provider (OpenAI, Anthropic, etc.).
• Resources: No local installation needed for hosted version. Self-hosting requires pnpm for building.
• Docs: Full documentation

Highlighted Details

• Supports multiple leading AI models through a single API endpoint.
• Automatic caching of results based on model, prompt, and seed for cost reduction.
• Offers enhanced request logging for observability and debugging.
• Deployable on Vercel, Cloudflare, AWS Lambda, or as an Express server.
