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 4.1, 5 Aug 2025): 200K-token window (OpenRouter model page, released 5 Aug 2025; the announcement itself states no window); list price $15 in / $75 out per 1M tokens = $30 blended at 3:1 (Anthropic: 'same as Opus 4'; Willison); text and image input. Anthropic/Willison: SWE-bench Verified 74.5%, original Terminal-Bench 43.3% (not Terminal-Bench 4.0, so coding null), GPQA Diamond 80.9%. Reasoning null (no launch-version AA index opened), speed null. Reviews: Zvi, Willison, The Decoder, CodeRabbit (code-review benchmark published 3 Oct 2025 that includes Opus 4.1; it tests the model, though after launch).[1]
It is still worth noting if you code, as there are many indications this is a larger practical jump in performance than one might think.
My favorite thing about this model is the version number - treating this as a .1 version increment looks like it's an accurate depiction of the model's capabilities.
Claude Opus 4.1 sets a record on the SWE-bench Verified benchmark, scoring 74.5 percent. That's about two points higher than Opus 4 and roughly five points ahead of OpenAI's o-series.
Opus 4.1 still produces the cleanest, most reliable actionable comments but that is to be expected given that it's a more expensive model.

Anthropic[3] 的发布文章标注日期为“2025 年 8 月 5 日”:“今天我们发布 Claude[2][4] Opus 4.1……现已面向付费 Claude 用户和 Claude Code 开放。它也已登陆我们的 API、Amazon Bedrock 和 Google Cloud 的 Vertex AI”;Claude 的发布说明和 GitHub[5] 的更新日志标注的日期相同。
"August 5, 2025 We've launched Claude[4] Opus 4.1, an incremental update to Claude Opus 4", which does not allow both temperature and top_p to be set; later entries record structured outputs launching for Opus 4.1 (14 November 2025) and its retirement.
Anthropic's[1] system card addendum: "Like Claude[2][4] Opus 4, Claude Opus 4.1 is deployed under the AI Safety Level 3 (ASL-3) Standard"; it is not "notably more capable" than Opus 4 under the RSP, so new evaluations were voluntary.
Anthropic[1][3] notified developers on 5 June 2026 that Claude[2] Opus 4.1 (claude-opus-4-1-20250805) would be retired; it was retired on 5 August 2026, one year after release, with claude-opus-4-8 as the replacement.
GitHub's changelog, "Release August 5, 2025": Claude[2][4] Opus 4.1, "the successor to Claude Opus 4", is available in GitHub Copilot Chat for Copilot Enterprise and Pro+ plans on github.com, Visual Studio Code and GitHub Mobile.
