Claude 3 Opus
Claude 3 Opus is a previous Anthropic flagship snapshot, not the live Opus default. A later leftover on this site is Claude Opus 4.5.
Compare Claude 3.5 Sonnet if you wanted the leftover 3.5 twin already rewritten as previous, and GPT-5.6 Sol if you wanted a current frontier chat model.
Key Features

- No invented 2026 dollar row for Opus 3: Confirm the overview before you quote a current 3 Opus price.
- No invented bench: Do not paste leftover "far exceeds expectations" as a 2026 census.
