TL;DR
bifrostLLM Infra · ★ 9.0k
When to choose:
- You operate high-throughput production AI applications and need an ultra-fast LLM gateway (50x faster than LiteLLM, <100 µs overhead at 5k RPS).
- You need unified access across 15+ model providers with automatic failover, adaptive load balancing, cluster mode, and semantic caching.
When to skip:
- You are running small low-traffic pet projects where direct provider SDK calls are sufficient without dedicated proxy infrastructure.
- You need visual prompt chaining, vector RAG pipelines, or chatbot web interfaces (Bifrost is an infra-level API router).
