**Legacy.** Released June 30, 2026.
Although Claude Sonnet 5 is still available, you should consider migrating to Claude Sonnet 5.5. [See Claude Sonnet 5.5](https://platform.claude.com/docs/pt-BR/models/sonnet-5-5/overview) · [Migrate to Claude Sonnet 5.5](https://platform.claude.com/docs/pt-BR/models/sonnet-5-5/migration-guide#migrating-from-claude-sonnet-5)
Model ID: `claude-sonnet-5`
Context window: 1M tokens · Max output: 128K tokens · Input pricing: $2 / MTok · Output pricing: $10 / MTok

## Como ele se compara à linha atual
| Model | Context | Max output | Price / MTok | Thinking | Default effort | Knowledge cutoff |
| :------------------------------------------------------------------------------------- | :------ | :--------- | :----------------- | :------------------- | :------------- | :--------------- |
| [Claude Fable 5.1](https://platform.claude.com/docs/pt-BR/models/fable-5-1/overview) | 1M | 128K | $10 / $50 | Adaptive (always on) | `high` | Jun 2026 |
| [Claude Opus 5.5](https://platform.claude.com/docs/pt-BR/models/opus-5-5/overview) | 1M | 128K | $4 / $20 | Adaptive (always on) | `medium` | Jun 2026 |
| [Claude Sonnet 5.5](https://platform.claude.com/docs/pt-BR/models/sonnet-5-5/overview) | 1M | 128K | $2 / $10 | Adaptive | `high` | Jun 2026 |
| **Claude Sonnet 5** (this model) | 1M | 128K | $2 / $10 | Adaptive | `high` | Jan 2026 |
| [Claude Haiku 5.5](https://platform.claude.com/docs/pt-BR/models/haiku-5-5/overview) | 1M | 128K | From $0.10 / $0.50 | Adaptive | `medium` | Jun 2026 |
* **Context:** 1M tokens is roughly 555k words or 2.5M Unicode characters on the current tokenizer (introduced with Claude Opus 4.7); models before it fit about 750k words in 1M tokens. 200k tokens is roughly 150k words.
* **Max output:** Synchronous Messages API limit. On the Message Batches API, Claude Opus 5.5, Claude Opus 5, Claude Sonnet 5.5, Claude Sonnet 5, Claude Haiku 5.5, Claude Opus 4.8, Claude Opus 4.7, Claude Opus 4.6, and Claude Sonnet 4.6 support up to 300k output tokens with the output-300k-2026-03-24 beta header.
* **Price / MTok:** Input / output, base price per million tokens. Batch API requests are 50% off; prompt caching reads cost 10% of the base input price (2.5% on Claude Fable 5.1 and Claude Mythos 5.1, 5% on Claude Opus 5.5 and Claude Sonnet 5.5). See Pricing for the full list.
* **Thinking:** Adaptive thinking lets the model decide how much to think, steered by effort. Extended thinking is the manual budget\_tokens mode on earlier models.
* **Default effort:** The effort parameter’s default on the Claude API. Models without a value don’t support the parameter.
* **Knowledge cutoff:** Reliable knowledge cutoff: the date through which the model’s knowledge is most extensive and reliable.

## Bom saber
* Na [Message Batches API](https://platform.claude.com/docs/pt-BR/build-with-claude/batch-processing#extended-output-beta), o Claude Sonnet 5 suporta até 300k tokens de saída com o cabeçalho beta `output-300k-2026-03-24`.
* Definir `temperature`, `top_p` ou `top_k` com valores diferentes do padrão retorna um erro 400.
* Consulte limites e capacidades programaticamente com a [Models API](https://platform.claude.com/docs/pt-BR/api/models/list).
