Nadir is a verifier-gated LLM router. Cheap model answers first, a calibrated verifier scores the response before it ships, and we escalate only when quality falls short. 60% cost reduction with 98% of always-Opus quality on RouterBench held-out prompts. #3 on RouterArena's public leaderboard. OpenAI-compatible, BYOK, two-line change.
Hey PH! I'm Dor, the maker of Nadir.
I built this because I was spending $800/mo on Claude Opus for an app where half the prompts were simple classifications and reformats. Switching those to Haiku manually meant maintaining routing logic that broke every time I changed a prompt. So I trained a classifier to do it automatically.
The key insight was adding a verifier, a second, lightweight check that catches when the classifier routes a hard prompt to a cheap model. That's what lets us promise 98% quality: the verifier is the safety net.
Where we are today:
60% average cost savings on real workloads
#3 on RouterArena, 92.1% on RouterBench (vs 27% for Not Diamond on the same set)
180ms routing overhead on CPU
Two lines to integrate — works with every OpenAI-compatible SDK
Would love your feedback, especially on routing quality. Try it on your weirdest prompts — that's where routers usually break, and where we've spent the most time.
