# Claude Sonnet 5

## Overview

Claude Sonnet 5, released by Anthropic on June 30, 2026, is the next generation of the Sonnet family and a drop-in upgrade for Claude Sonnet 4.6. It is designed for stronger agentic behavior, coding, tool use, computer-use workflows, and knowledge work at Sonnet-tier pricing.

## Key Features

* **Agentic Task Execution**: Designed to plan, use tools such as browsers and terminals, and complete multi-step work more reliably than Claude Sonnet 4.6.
* **Adaptive Thinking by Default**: Requests run with adaptive thinking unless `thinking: {type: "disabled"}` is passed; the `effort` parameter controls the capability, latency, and token-spend tradeoff.
* **1M Context Window**: Supports a 1M-token context window by default, with no smaller context variant and no long-context surcharge.
* **Broad Platform Availability**: Available through the Claude API, Claude Code, Claude Platform on AWS, Amazon Bedrock, Google Cloud, Microsoft Foundry preview, and Claude consumer plans.

## Best Use Cases

* **Production Agent Workflows**: Multi-step automation, agentic search, tool-heavy reasoning, browser/terminal workflows, and long-running delegated tasks.
* **Software Engineering**: Coding, debugging, refactoring, code review, test-fix loops, and brownfield repository work where follow-through matters.
* **High-Volume Knowledge Work**: Research, analysis, structured extraction, business operations, legal research, customer workflows, and internal productivity tools that need a balance of capability and cost.

## Capabilities and Limitations

| Capability | Description |
| :------------------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **Reasoning** | Adaptive thinking is on by default; `effort` supports `low`, `medium`, `high`, `xhigh`, and `max`, with `high` as the default. Anthropic reports stronger agentic, coding, and knowledge-work performance than Sonnet 4.6. |
| **Creative Writing** | Supports general text generation and long-form writing; Anthropic recommends re-evaluating style prompts because prose style may shift versus earlier Sonnet models. |
| **Multimodal** | Text and image input, text output, multilingual capabilities, and vision. Native audio/video input or generation is not listed. |
| **Response Speed** | Listed with "Fast" comparative latency in Anthropic's model table. Lower effort can reduce latency and token usage; higher effort increases thinking/tool-use depth. |
| **Context Window** | 1M tokens. |
| **Max Output** | 128K tokens. |
| **Tool Use** | Supports the same tool and platform feature set as Claude Sonnet 4.6 except Priority Tier is not available; tool use is more readily triggered at higher effort levels. |
| **Multilingual** | Official docs state multilingual support across current Claude models, but do not publish a separate Sonnet 5 language benchmark. |

### Known Limitations

* Manual extended thinking (`thinking: {type: "enabled", budget_tokens: N}`) is removed and returns a 400 error; use adaptive thinking with `effort` instead.
* Non-default sampling parameters (`temperature`, `top_p`, `top_k`) return a 400 error; use system instructions for tone and style control.
* Assistant message prefilling remains unsupported and returns a 400 error.
* The new tokenizer produces approximately 30% more tokens for the same text than Claude Sonnet 4.6, so token budgets, context usage, and equivalent-request costs should be remeasured.
* Cybersecurity safeguards are enabled by default; high-risk or prohibited cybersecurity requests may be refused with `stop_reason: "refusal"`.

:::info Pricing note
The main pricing table shows the currently effective standard reference price. For Claude Sonnet 5, the current standard reference price applies through August 31, 2026. Prices shown in the documentation are B.AI standard reference prices for base billing purposes. B.AI may provide lower actual usage costs through top-up bonuses and account benefits. Specific prices, bonus Credits, and account benefits are subject to the platform display and final billing records.

:::caution Main table scope
The main pricing table shows the currently effective standard reference price for each model. The `Cache Write` column represents the billing rate when cache writing occurs; it does not imply a unified cache TTL across all models. Cache behavior, retention time, and extended caching options may vary by model provider. If a model has special caching rules, 1-hour cache write pricing, or time-based pricing, please refer to the corresponding model detail page.

# Claude Sonnet 5

## 概述

Claude Sonnet 5 是 Anthropic 于 2026 年 6 月 30 日发布的新一代 Sonnet 系列模型，可作为 Claude Sonnet 4.6 的直接升级版本。该模型面向更强的 Agent 行为、代码能力、工具调用、计算机使用工作流和知识工作场景，并保持 Sonnet 级别的价格定位。

## 核心特性

* **Agentic Task Execution**：面向规划、浏览器和终端等工具使用，以及更可靠的多步骤任务完成能力。
* **默认自适应思考**：请求默认使用 adaptive thinking，除非传入 `thinking: {type: "disabled"}`；`effort` 参数用于控制能力、延迟和 token 消耗之间的权衡。
* **1M 上下文窗口**：默认支持 1M tokens 上下文窗口，没有更小上下文变体，也没有长上下文额外费用。
* **广泛平台可用性**：可通过 Claude API、Claude Code、AWS 上的 Claude Platform、Amazon Bedrock、Google Cloud、Microsoft Foundry preview 和 Claude 消费者计划使用。

## 适用场景

* **生产级 Agent 工作流**：多步骤自动化、Agentic Search、工具密集型推理、浏览器/终端工作流，以及长时间委托任务。
* **软件工程**：代码生成、调试、重构、代码审查、测试修复循环，以及既有代码仓库维护。
* **高频知识工作**：研究、分析、结构化抽取、业务运营、法律研究、客户工作流和内部生产力工具。

## 能力与限制

| 能力维度 | 说明 |
| :--- | :--- |
| **推理能力** | 默认启用 adaptive thinking；`effort` 支持 `low`、`medium`、`high`、`xhigh` 和 `max`，默认值为 `high`。Anthropic 表示其 Agent、代码和知识工作能力强于 Sonnet 4.6。 |
| **创意写作** | 支持通用文本生成和长文写作；Anthropic 建议重新评估样式提示词，因为相较早期 Sonnet 模型，文本风格可能发生变化。 |
| **多模态能力** | 支持文本和图像输入、文本输出、多语言能力和视觉理解；未列出原生音频/视频输入或生成能力。 |
| **响应速度** | 在 Anthropic 模型表中被标记为 "Fast"；较低 effort 可降低延迟和 token 使用，较高 effort 会增加思考和工具使用深度。 |
| **上下文窗口** | 1M tokens |
| **最大输出** | 128K tokens |
| **工具调用** | 支持与 Claude Sonnet 4.6 相同的工具和平台能力集，但不支持 Priority Tier；更高 effort 下更容易触发工具使用。 |
| **多语言能力** | 官方文档表示当前 Claude 模型支持多语言，但未单独公布 Sonnet 5 的语言覆盖基准。 |

### 已知限制

* 已移除手动 extended thinking（`thinking: {type: "enabled", budget_tokens: N}`），使用该参数会返回 400 错误；请改用 adaptive thinking 和 `effort`。
* 非默认采样参数（`temperature`、`top_p`、`top_k`）会返回 400 错误；建议使用 system instructions 控制语气和风格。
* 不支持 assistant message prefilling，使用时会返回 400 错误。
* 新 tokenizer 对同一文本可能比 Claude Sonnet 4.6 多产生约 30% tokens，因此 token 预算、上下文使用量和等效请求成本需要重新评估。
* 默认启用网络安全防护；高风险或禁止的网络安全请求可能会以 `stop_reason: "refusal"` 被拒绝。

## 积分消耗

| 模型名称 | 价格周期 | 输入 (Credits/Token) | 5m Cache Write (Credits/Token) | 1h Cache Write (Credits/Token) | Cache Read (Credits/Token) | 输出 (Credits/Token) | 网页搜索（Credits/次） |
