Claude Sonnet 5.5（Anthropic） Claude Sonnet 5.5 (Anthropic)

Claude Sonnet 5.5 (Anthropic)

Anthropic 于 2026-09-28 发布的 Claude 5.5 家族第二款模型。官方页正文称：相对 Claude Sonnet 5 为明确升级，生成快 30%+，多数工作花费可低至 30%；价目与 Sonnet 5 同为输入 $2 / 输出 $10 / cache reads $0.20 每百万 token，但因 token 更少所以更便宜。定位为 Opus 5.5 的更快、更低成本补位：擅长边界清晰的日常任务、修 bug、做文档 / 幻灯 / 表格，并写有较锐的设计眼。官方表（列 Sonnet 5.5 / Sonnet 5 / Opus 5.5 / GPT-6 Sol）：Terminal-Bench 4.0 70.6% / 10.3% / 66.4%¹ / —；CursorBench 4.0 55.5% / 34.1% / 57.8% / —；GDPval-AA v2.1 1844 / 1449 / 1846 / 1487⁴。平台模型 id：`claude-sonnet-5-5`；称已在全平台可用（含 AWS / Google Cloud / Azure），零数据保留与 Opus 5.5 / Sonnet 5 相同。第三方榜 Artificial Analysis https://artificialanalysis.ai/models/claude-sonnet-5-5（变体 Adaptive Reasoning, Max Effort, Default Fallback，晚间 GET 200）：Intelligence Index 56，输出速度 138.7 tok/s（#29/216），价 $2/$10、Cache Discount 90%、每任务 $7.60，1M 上下文。晨间目录未收（当日只收 Jeff + HTML），晚间补上。 Anthropic’s second model in the Claude 5.5 family, announced 2026-09-28. The page calls it a clear upgrade over Claude Sonnet 5: 30%+ faster generation and up to 30% less cost for most work, at the same list price as Sonnet 5 — $2 input / $10 output / $0.20 cache reads per 1M tokens — because it typically uses fewer tokens. Positioned as a faster, lower-cost complement to Opus 5.5 for well-scoped everyday tasks, bug fixes, and polished documents, slides, and spreadsheets, with a noted eye for design. Vendor table (columns Sonnet 5.5 / Sonnet 5 / Opus 5.5 / GPT-6 Sol): Terminal-Bench 4.0 70.6% / 10.3% / 66.4%¹ / —; CursorBench 4.0 55.5% / 34.1% / 57.8% / —; GDPval-AA v2.1 1844 / 1449 / 1846 / 1487⁴. Platform model id: claude-sonnet-5-5; the page says it is available on all platforms including AWS / Google Cloud / Azure, with the same zero data retention as Opus 5.5 / Sonnet 5. Third-party board Artificial Analysis https://artificialanalysis.ai/models/claude-sonnet-5-5 (variant Adaptive Reasoning, Max Effort, Default Fallback, evening GET 200): Intelligence Index 56, 138.7 tok/s (#29/216), $2/$10, Cache Discount 90%, $7.60 per task, 1M context. Morning catalog skipped it (Jeff + HTML only); this evening wave picks it up.

为什么推荐Why we recommend it 页内写 Opus 5.5 在复杂开放工作上仍更强，故不把 Sonnet 写成「全面第一」。同板已有 claude-opus-5-5；互链只表示同家族，不表示评测对齐。整理质量 4 星（来源齐、边界清），不代表基准分。 The page itself says Opus 5.5 remains stronger on complex open-ended work — Sonnet is not framed as first everywhere. Same-board claude-opus-5-5 cross-link is family-only, not an aligned eval claim.

要点（官方称 / 社区称）Highlights (vendor / community claims)

  • 官方称：Claude 5.5 家族第二款；相对 Sonnet 5 明确升级，生成快 30%+，多数工作花费可低至 30%；价目与 Sonnet 5 同为 $2/$10/$0.20，因 token 更少而更便宜。平台 id：claude-sonnet-5-5；称全平台可用（含 AWS / Google Cloud / Azure）。同页写 Haiku 5.5 将在随后数周加入家族。 Vendor claim: second model in the Claude 5.5 family; a clear upgrade over Sonnet 5 with 30%+ faster generation and up to 30% lower cost for most work at the same $2/$10/$0.20 list price, because it uses fewer tokens. Platform id claude-sonnet-5-5; claimed available on all platforms including AWS / Google Cloud / Azure. The same page says Haiku 5.5 joins the family in the coming weeks.
  • 官方称（对照表节选，列 Sonnet 5.5 / Sonnet 5 / Opus 5.5 / GPT-6 Sol）：Terminal-Bench 4.0 70.6% / 10.3% / 66.4%¹ / —；CursorBench 4.0 55.5% / 34.1% / 57.8% / —；GDPval-AA v2.1 1844 / 1449 / 1846 / 1487⁴；OSWorld 2.1 80.1% partial / 57.0% / 81.8% / —。页注：¹ Opus 5.5 为 Xhigh；并写 Opus 5.5 在复杂、开放式、需持续判断的工作上仍明显更强。本库未复跑。 Vendor claim (table excerpt, columns Sonnet 5.5 / Sonnet 5 / Opus 5.5 / GPT-6 Sol): Terminal-Bench 4.0 70.6% / 10.3% / 66.4%¹ / —; CursorBench 4.0 55.5% / 34.1% / 57.8% / —; GDPval-AA v2.1 1844 / 1449 / 1846 / 1487⁴; OSWorld 2.1 80.1% partial / 57.0% / 81.8% / —. Page note: ¹ Opus 5.5 at Xhigh; the page also says Opus 5.5 remains clearly stronger on complex, open-ended work needing sustained judgment. Not re-run here.
  • 官方称：网络安全能力接近 Opus 5，故为首个带与顶尖模型类似 cyber 保障与回退的 Sonnet；生物学保障与 Sonnet 5 相同；另写首个带防蒸馏分类器与扩展 preserved thinking 的 Sonnet。常规软件开发与多数生命科学工作自称不受影响。本库未测安全策略。 Vendor claim: cybersecurity capabilities comparable to Opus 5, so it is the first Sonnet to ship with cyber safeguards and fallbacks like the top models; biology safeguards match Sonnet 5; also the first Sonnet with distillation-attack classifiers and expanded preserved thinking. Routine software development and most life-sciences work are claimed unaffected. Safeguard policy not tested here.
  • 第三方榜（Artificial Analysis，非官方、非本库）：页面标题 “Claude Sonnet 5.5 (max with fallback)”，变体 Adaptive Reasoning, Max Effort, Default Fallback；Intelligence Index 56；输出 138.7 tok/s（#29/216）；价输入 $2.00 / 输出 $10.00、Cache Discount 90%、Cost per Intelligence Index task $7.60；Verbosity 410M output tokens（#102/216）；1M 上下文；发布月 September 2026 / FAQ 写 released September 28, 2026。不把 AA 数字与官方页基准合成新指标。 Third-party board (Artificial Analysis — neither vendor nor this library): page title “Claude Sonnet 5.5 (max with fallback)”, variant Adaptive Reasoning, Max Effort, Default Fallback; Intelligence Index 56; 138.7 tok/s (#29/216); $2.00 input / $10.00 output, Cache Discount 90%, $7.60 per Intelligence Index task; verbosity 410M output tokens (#102/216); 1M context; release month September 2026 / FAQ says released September 28, 2026. AA figures are not merged with the vendor table into a new metric.

GPT-6.1 Sol（OpenAI） GPT-6.1 Sol (OpenAI)

GPT-6.1 Sol (OpenAI)

OpenAI 于 2026-09-29 发布的 GPT-6 Sol 升级款。官方称：在 agentic coding、电脑操作与专业工作上几乎对齐 GPT-6 Astra，标准输入与输出 token 价格约为 Astra 的五分之一。标准 API 价：输入 $2 / 缓存输入 $0.10 / 输出 $10 每百万 token；缓存输入官方称比标准输入少 95%、比 GPT-6 Sol 的缓存输入少 50%。API id：`gpt-6.1-sol`。可用性：Plus / Pro / Business / Enterprise / Edu 的 ChatGPT Work 与 Codex；尚未进入 Chat；API 已可用。Ultrafast 官方称将在随后数日推出，在 Codex 里相对标准速度最高 8 倍 token 生成。第三方榜 Artificial Analysis https://artificialanalysis.ai/models/gpt-6-1-sol（GPT-6.1 Sol (max)，晚间 GET 200）：Intelligence Index 52（#10/222），67.8 tok/s（#107/222），价 $2/$10、Cache Discount 95%、每 Intelligence Index 任务 $0.72，1M 上下文，发布日 2026-09-29。AA 文章称 GPT-6 Sol 在 7 天后被 6.1 Sol 接替，约比 Astra II 低 1 分、每任务成本不到其四分之一。晨间 changelog 把通用 DevDay 新闻排除在 A/B/C 之外、未收本模型（板上只有 gpt-6-astra），晚间补进 Models。 OpenAI’s upgrade to GPT-6 Sol, announced 2026-09-29. Vendor claim: it nearly matches GPT-6 Astra on agentic coding, computer use, and professional work at about one-fifth of Astra’s standard input and output token prices. Standard API price: $2 input / $0.10 cached input / $10 output per million tokens; cached input is claimed 95% less than standard input and 50% less than GPT-6 Sol’s cached input. API id: gpt-6.1-sol. Availability: Plus / Pro / Business / Enterprise / Edu in ChatGPT Work and Codex; not yet in Chat; API is available. Ultrafast is claimed for the coming days, up to 8× faster token generation versus standard speed in Codex. Third-party board Artificial Analysis https://artificialanalysis.ai/models/gpt-6-1-sol (GPT-6.1 Sol (max), evening GET 200): Intelligence Index 52 (#10/222), 67.8 tok/s (#107/222), $2/$10, Cache Discount 95%, $0.72 per Intelligence Index task, 1M context, released 2026-09-29. The AA article says GPT-6 Sol was replaced by 6.1 Sol after 7 days, about 1 point below Astra II at under a quarter of the cost per task. Morning changelog kept generic DevDay news out of A/B/C and did not file this model (the board only had gpt-6-astra); this evening wave adds it to Models.
