Intelligence index

A 0–100 composite from public benchmarks: MMLU-Pro, GPQA Diamond, HumanEval, ARC-AGI v2, and Arena Elo (LMArena), normalized and weighted. We do not run our own evaluations — every score is cited back to its source so you can audit it via the model drawer.

Pricing

Taken from each provider's official pricing page on the date in last_verified. Multi-modal pricing is split into typed fields (input, output, cached, batch, per image, per minute, per second).

Updates

A daily automated routine pings each provider's /models endpoint, diffs against the registry, and queues changes for review. A human approves every update before it ships — no silent edits.

Caching

Edge cache: s-maxage=300, stale-while-revalidate=86400. Even if our origin is down for 24h, Cloudflare keeps serving stale responses, so your app never sees a hard failure.
