Keywords AI
LLM observability and gateway platform, formerly Keywords AI, that routes calls to 500+ models and monitors cost, latency, and errors.
About
Respan, previously known as Keywords AI, is an LLM engineering platform that acts as a unified gateway for routing AI traffic across more than 500 models from different providers. It handles automatic failover when a model errors or hits rate limits, applies per-key spend controls, and caches responses to reduce cost. On the observability side, every request is traced with full latency breakdown, and dashboards show usage by model, user, and time period. Teams can set up evaluations that mix rule-based checks, LLM judges, and human review to score live production traffic. A free API key tier is available with upgrade options for higher volume.
