Estimate from the version's published specs, benchmarks and reviews, 0-5; scores are only comparable within one criteria year. Scored as launched (Claude Opus 4.8, 28 May 2026): Artificial Analysis Intelligence Index 61.4 (max effort, #1) per its 28 May 2026 launch article, the index version then current; the live AA page now lists 42 on v4.3.2, which is why launch-time figures are used. Coding null: no Terminal-Bench 4.0 at launch (Anthropic cites Terminal-Bench 2.x). 1M-token context; $5/$25 per 1M (about $10 blended); Fast mode $10/$50. 63.0 output tokens/s on Artificial Analysis (live page, 24 Oct 2026). Text and image input. 4 reviews, string-matched.[1]
Opus 4.8 scores 61.4, up +4.1 points from Opus 4.7 and +1.2 points ahead of GPT-5.5 (xhigh), the previous Index leader.
It's so refreshing to see an AI lab honestly describe a release as a minor incremental improvement over the previous model!
But Opus 4.8 still uses roughly 30 percent more passes than OpenAI's GPT-5.5, the second-place model.
Claude immediately offered a sharp realistic reality check that gently but firmly suggested my 'couch detective' career was nothing more while setting firm boundaries about the dangers of amateur sleuthing.
