What it solves

Bifrost is a high-performance AI gateway that simplifies the management of multiple AI providers. It eliminates the need to integrate multiple different APIs by providing a single, OpenAI-compatible interface for over 23 providers, including OpenAI, Anthropic, AWS Bedrock, and Google Vertex. It also addresses reliability issues like provider downtime by offering automatic failover and load balancing.

How it works

Bifrost acts as a proxy layer between your application and various AI model providers. You can deploy it as an HTTP API gateway (via Docker or NPX) or integrate it directly as a Go SDK. It translates requests from a unified API format into provider-specific calls and manages the routing, caching, and governance of those requests.

Who it’s for

Developers and enterprise teams building production AI applications who need a unified way to manage multiple LLM providers, ensure high availability, and control costs through budget management and governance tools.

Highlights

• Unified Interface: A single OpenAI-compatible API for 23+ providers.
• Reliability Tools: Automatic fallbacks and intelligent load balancing across API keys and providers.
• Semantic Caching: Reduces latency and costs by caching responses based on semantic similarity.
• Model Context Protocol (MCP): Allows AI models to interact with external tools like databases and web search.
• Enterprise Governance: Includes budget management, OIDC user provisioning, and native Prometheus metrics for observability.
• High Performance: Extremely low overhead, adding as little as 11 µs of latency per request in high-load benchmarks.
