Claude Haiku 5.5
Anthropic released Claude Haiku 5.5, which it calls its cheapest, fastest, and most capable small model to date. It targets high-volume work such as summaries, compaction, classification, and subagent tasks under Opus 5.5 and Sonnet 5.5, and costs around 75% less to run than Haiku 4.5 on average.
Anthropic 发布了 Claude Haiku 5.5，称其为迄今为止最便宜、最快且能力最强的小型模型。它针对高吞吐量任务，如摘要、压缩、分类以及在 Opus 5.5 和 Sonnet 5.5 下的子代理任务，平均运行成本比 Haiku 4.5 低约 75%。
- Agentic performance: 72.4% on the OSWorld 2.1 offline subset against 15.7% for Haiku 4.5, 39.2% on Terminal-Bench 4.0 against 0.0%, and a GDPval-AA v2.1 Elo of 1620 against 735.
- Pricing: $0.10 input, $0.50 output, and $0.01 cache reads per million tokens for prompts up to 100K tokens, which covered about 90% of Haiku 4.5 requests. Longer prompts cost $0.50 input and $2.50 output.
- Effort control: It is the first Haiku model with an adjustable effort setting, so developers can trade cost for intelligence per task.
- Wider price changes: Sonnet 5.5 cache reads drop from $0.20 to $0.10 per million tokens, cutting its cost on most agentic work by around 20%. Max and Team subscribers get monthly API credits of $100 to $500, and the Python and TypeScript SDKs add computer use and browser use in beta.
- Availability: Live as claude-haiku-5-5 on all platforms, including AWS, Google Cloud, and Azure.
- 智能体性能：在 OSWorld 2.1 离线子集上达到 72.4%，而 Haiku 4.5 为 15.7%；在 Terminal-Bench 4.0 上达到 39.2%，而 Haiku 4.5 为 0.0%；在 GDPval-AA v2.1 Elo 评分中达到 1620，而 Haiku 4.5 为 735。
- 定价：对于高达 100K token 的提示词（覆盖约 90% 的 Haiku 4.5 请求），输入价格为每百万 token $0.10，输出为 $0.50，缓存读取为 $0.01。更长的提示词输入价格为 $0.50，输出价格为 $2.50。
- 努力程度控制：这是首款具有可调节努力设置的 Haiku 模型，因此开发者可以按任务权衡成本与智能水平。
- 更广泛的定价调整：Sonnet 5.5 的缓存读取价格从每百万 token $0.20 降至 $0.10，使其在大多数智能体工作中的成本降低约 20%。Max 和 Team 订阅用户每月可获得 $100 至 $500 的 API 额度，Python 和 TypeScript SDK 新增了处于测试阶段的计算机使用和浏览器使用功能。
- 可用性：在所有平台（包括 AWS、Google Cloud 和 Azure）上以 claude-haiku-5-5 形式上线。
