In the last 24 hours we dispatched 1,556 tasks across 4 models. Here's what we picked, and why.

What we ran

An autonomous AI fleet, written in TypeScript, picks a model per task using a complexity router. No vibes, no PR team. This is the actual production output of that router:

ModelDispatchesShareWhy this one
01 claude-sonnet-4-6 1,066 68.5% implementation (standard)
02 claude-haiku-4-5 278 17.9% implementation (light)
03 gpt-5.4-mini 189 12.1% implementation (codex pool)
04 claude-opus-4-6 23 1.5% implementation (high complexity)

Window: 24h to 2026-05-16T00:00:00Z. Source: daemon routing logs. The router writes a decision per dispatch; we parsed 1556 of them.

If you don't have a router, here are the picks per common task

Filtered from arena.ai's leaderboard plus published API prices. Filter thresholds are listed under each tab; arguable. Treat this as a starting shortlist, not a verdict.

High-stakes code generation and refactor. Quality is the only thing that matters.

Filter: Coding leaderboard, quality ≥ 1400, sorted by raw score. Price is secondary — a wrong PR costs more than a smarter model. 170 models survived.

What this is, and isn't

Right now this is filter-on-arena.ai plus a public log of what we ran. Arena Elo measures pairwise human preference on short prompts. It does not measure: whether a model produces valid JSON under a schema, whether it hallucinates function names, whether it refuses queries it shouldn't, latency p99, rate-limit behaviour. Production teams need those signals.

We're building a benchmark runner — fixed prompt suites for RAG, structured extraction, code refactoring, function calling — run daily against every model. Raw inputs, outputs, judge rationale, costs published. When that lands, the "picks" section gets its real backing. Until then, the picks section is opinion with a citation, not measurement.
