Claude Haiku 5.5：Anthropic 最便宜、最快的小模型，价格约降四分之三 Claude Haiku 5.5: Anthropic's cheapest, fastest small model, about 75% cheaper to run

Claude Haiku 5.5: Anthropic's cheapest, fastest small model, about 75% cheaper to run

Anthropic 2026-10-07 发布 Claude Haiku 5.5，定位是量大、怕贵、要快的活：摘要、分类、数据库查询、在线客服、操作浏览器，或者给 Opus 5.5、Sonnet 5.5 当写代码时的小帮手。官方说平均跑起来比 Haiku 4.5 便宜约 75%。价格按每百万 token 算，提示词在 10 万 token 以内时输入 0.10 美元、输出 0.50 美元，超过 10 万时是 0.50 和 2.50。这是第一款能调「思考力度」的 Haiku。同一天 Sonnet 5.5 的缓存读取降价一半，Max 和 Team 订阅也开始送每月 API 额度。平台模型名 claude-haiku-5-5，各大云平台都能用。 Anthropic released Claude Haiku 5.5 on 2026-10-07 for high-volume, cost- and speed-sensitive work: summaries, classification, database queries, live customer support, browser use, or helping Opus 5.5 and Sonnet 5.5 as a coding subagent. Anthropic says it costs about 75% less to run than Haiku 4.5 on average. Per million tokens, prompts up to 100K are $0.10 input and $0.50 output; over 100K, $0.50 and $2.50. It is the first Haiku with an adjustable effort setting. The same day, Sonnet 5.5 cache reads were halved and Max and Team subscriptions got a monthly API credit. Platform model id claude-haiku-5-5, available on the major clouds.

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

  • 适合干什么：大量的短活，比如摘要、压缩上下文、查库、分类、在线客服、操作浏览器；或者大模型做主力、它当子代理去查资料。官方自己也写：复杂的代码任务还是 Sonnet 5.5、Opus 5.5 更合适。 What it's for: lots of short jobs such as summaries, context compaction, database queries, classification, live support, and browser use, or serving as a subagent that fetches facts for a bigger model. Anthropic itself says Sonnet 5.5 and Opus 5.5 remain better for complex coding.
  • 价格（每百万 token，提示词 ≤10 万 / >10 万）：输入 0.10 / 0.50 美元，输出 0.50 / 2.50 美元，缓存读取 0.01 / 0.05 美元，缓存写入 0.125 / 0.625 美元。对照 Haiku 4.5：输入 1 美元、输出 5 美元。官方说以前 Haiku 约九成请求在 10 万 token 以内。 Pricing (per million tokens, prompts ≤100K / >100K): input $0.10 / $0.50, output $0.50 / $2.50, cache reads $0.01 / $0.05, cache writes $0.125 / $0.625. For comparison, Haiku 4.5 is $1 input and $5 output. Anthropic says about 90% of previous Haiku requests were under 100K tokens.
  • 官方表节选，本库未复跑（列 Haiku 5.5 / Haiku 4.5 / GPT-6 Luna / Sonnet 5.5）：OSWorld 2.1 离线子集 72.4% / 15.7% / 48.9% / 83.9%；Terminal-Bench 4.0 39.2% / 0.0% / 16.4% / 70.6%；GDPval-AA v2.1 1620 / 735 / 1437 / 1840。 Vendor table excerpt, not re-run here (columns Haiku 5.5 / Haiku 4.5 / GPT-6 Luna / Sonnet 5.5): OSWorld 2.1 offline subset 72.4% / 15.7% / 48.9% / 83.9%; Terminal-Bench 4.0 39.2% / 0.0% / 16.4% / 70.6%; GDPval-AA v2.1 1620 / 735 / 1437 / 1840.

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.

GPT-6 进 ChatGPT 聊天：回答会直接长出可点的界面（Intelligent UI） GPT-6 comes to ChatGPT chat: answers can arrive as interactive interfaces (Intelligent UI)

GPT-6 comes to ChatGPT chat: answers can arrive as interactive interfaces (Intelligent UI)

OpenAI 2026-10-07 发布：GPT-6 进入 ChatGPT 的聊天页，免费用户也有。最大的变化叫 Intelligent UI：回答不再只是文字，模型会自己决定要不要配图表、按钮、表单、地图或可交互的示意图，比如拆解一辆 7 速自行车的结构可以点着看，也能当场做一个存钱计算器或分账小工具。官方说背后是一套能边生成边显示的原生组件库加一个编译器，并专门训练了模型做版式和交互的取舍，什么时候纯文字就够也算在内。付费档（Plus、Pro、Business、Enterprise）用 GPT-6 Sol，免费和 Go 档用 GPT-6 Luna；10-07 起付费档上线，次日扩到免费档。官方还说 GPT-6 能边想边答，联网问题的 Instant 版平均早 44% 开始出字。Work 和 Codex 里的模型这次不变。 OpenAI, 2026-10-07: GPT-6 comes to ChatGPT's chat tab, free users included. The headline change is Intelligent UI: instead of text only, the model decides whether to add charts, buttons, forms, maps, or interactive diagrams, so a breakdown of a 7-speed bike becomes something you tap through, and it can build a savings calculator or bill splitter on the spot. OpenAI says this runs on a library of native, streamable components plus a compiler, and that the model was trained to make layout and interaction choices, including when plain text is enough. Paid tiers (Plus, Pro, Business, Enterprise) get GPT-6 Sol; Free and Go get GPT-6 Luna. Paid rollout starts 10-07 and expands to Free the next day. OpenAI also says GPT-6 can start answering while it keeps thinking, with Instant starting 44% sooner on average for web-search questions. Models in Work and Codex are unchanged.
