Free evals API for AI startups (ship 10x faster with evals you can trust)

Hey HN,

We built Composo because AI apps fail unpredictably and teams have no idea if their changes helped.

LLM-as-judge doesn't work - it gives random scores, doesn't work well for agents, and doesn't tell you what to fix.

We've built purpose-built evaluation models that give you: - Deterministic scores (same input = same score, always) - Instant identification of where prompts, retrievals, agents & tool calls fail - Exact failure analysis ("tool calls are looping due to poorly specified schema")

We're 92% accurate vs 72% for SOTA LLM-as-judge.

Giving 10 startups free access: - 10k eval credits - Just launched our evals API for agents & tool calling - 5 min setup

Already helping teams at Palantir, Accenture, and Tesla ship reliable AI.
