Estimate from the version's published specs, benchmarks and reviews, 0-5; scores are only comparable within one criteria year. Scored as launched (Claude Sonnet 5, 30 Jun 2026): Artificial Analysis Intelligence Index 53 (max effort, index v4.1) as reported by The Decoder on 1 Jul 2026; the live AA page now shows 38 on v4.3.2. Coding null: Terminal-Bench 4.0 was not measured at launch (Anthropic reports Terminal-Bench 2.1, 80.4%). 1M-token context; introductory $2 in / $10 out per 1M (about $4 blended) through 31 Aug 2026, then made permanent on 10 Aug; AA ran at the earlier $3/$15 standard rate (price would be 3). 83.5 output tokens/s on Artificial Analysis (live page, 24 Oct 2026). Text and image input. 4 reviews, string-matched.[1]
Sonnet 5 scored 53 points at peak performance, tying with GPT-5.5 (high) for fifth place.
On that front, Claude Sonnet 5 feels extremely capable.
