Best for
- Production coding and integrations at $2/$10
- Computer-use agents (81.2% OSWorld, vendor-reported)
- 1M-context work without flagship pricing
Watch out
Opus still leads hard agentic coding — 69.2% vs 63.2% SWE-Bench Pro, which Anthropic states plainly. Launch benchmarks are vendor-reported. Anthropic cancelled the planned September price increase; current standard pricing is $2/$10 (checked 2026-09-07).
For creators. The reliable default for content-engine and production coding work. Route to Opus only when the task earns the premium.
