Peer public (main number / bar) ranks this Build inside the current scored peer set (≈40–95). Raw is the absolute evidence-fusion aggregate before min-max. A low peer score can still be a strong absolute model — see methodology.

Practical verdict

When to choose

Best at
  • Long-horizon coding agents (named harnesses)
  • Terminal / DevOps-style multi-step work
  • Mixed professional workflows with strong tool use
Avoid for
  • Latency-first everyday chat (use lower effort or Luna/Terra)
  • Strict budget token farms
  • Trust-critical judgment without verification (high Omniscience hall pattern)
Choose this when

You want OpenAI tooling + max-effort frontier performance on hard multi-step jobs.

Traits & Quirks

Signature strengths and honest flaws

No structured traits or flaws catalogued for this Build yet. Traits are behavioural patterns (beyond raw scores) — added as evidence and field observation accumulate. See Best at / Avoid for above in the meantime.

Engine pass meth_v0_1_1 (peer min-max vs scored launch peer set). Codex overall 79.7 (B). Attribute public scores map raw aggregates into a 40–95 band within the peer set (methodology min-max). INT uses hierarchical fusion (GPQA primary / HLE secondary / capped bleed).
