Data-backed recommendation

Avoid this pick if

You are latency- or cost-sensitive, or your tasks don't need frontier-level reasoning — Opus 4.8 at half the price is plenty.

Strengths

80.3% SWE-Bench Pro — the new #1, up from Opus 4.8's 69.2% and GPT-5.5's 58.6%

1932 on GDPval-AA, ahead of Opus 4.8 (1890) and GPT-5.5 (1769)

1M-token context at standard pricing, 128K max output per request

Mythos-class capability released for general use with new cyber-risk safeguards

Weaknesses

Priced at $10/$50 per 1M tokens — double Opus 4.8 ($5/$25)

Deliberate pace; not for latency-sensitive interactive apps

Standard-use safeguards block some high-risk security workloads (use Mythos 5 with partner access)

Ranked alternatives

Strong backups depending on your budget, workload, and preferred tradeoffs.
