--- title: Claude Opus 5.5 url: https://platform.claude.com/docs/pt-BR/models/opus-5-5/overview description: "Claude Opus 5.5 em resumo: para que serve, IDs do modelo em todas as plataformas, janela de contexto, limites de saída, preços, disponibilidade e os guias e recursos para construir com ele." --- **Latest.** Released September 22, 2026. For long-running agentic coding and knowledge work Model ID: `claude-opus-5-5` Context window: 1M tokens · Max output: 128K tokens · Input pricing: $4 / MTok · Output pricing: $20 / MTok [Announcement](https://www.anthropic.com/claude-opus-5-5) · [What’s new](https://platform.claude.com/docs/pt-BR/models/opus-5-5/whats-new-opus-5-5) · [Migration guide](https://platform.claude.com/docs/pt-BR/models/opus-5-5/migration-guide) ## Visão geral O Claude Opus 5.5 foi criado para codificação agêntica de longa duração e trabalho de conhecimento, com preço de $4 / $20 USD por milhão de tokens de entrada / saída. Quatro "breaking changes" (mudanças incompatíveis) afetam código que já roda no Claude Opus 5: [o pensamento não pode ser desativado](https://platform.claude.com/docs/pt-BR/models/opus-5-5/whats-new-opus-5-5#thinking-cant-be-disabled), [o uso forçado de ferramentas retorna um erro](https://platform.claude.com/docs/pt-BR/models/opus-5-5/whats-new-opus-5-5#forced-tool-use-is-not-supported), [os blocos de pensamento estão vinculados ao modelo e à conversa](https://platform.claude.com/docs/pt-BR/models/opus-5-5/whats-new-opus-5-5#thinking-blocks-are-tied-to-the-model-that-produced-them) e, na Claude API e no Google Cloud, [a ferramenta anterior de "computer use" (uso de computador) `computer_20251124` não é aceita](https://platform.claude.com/docs/pt-BR/models/opus-5-5/whats-new-opus-5-5#computer-20251124-is-not-supported). As três primeiras também se aplicam ao Claude Fable 5.1. Outra mudança altera o formato da resposta sem fazer nenhuma requisição falhar: [o texto entre chamadas de ferramentas volta em blocos `thinking`](https://platform.claude.com/docs/pt-BR/models/opus-5-5/whats-new-opus-5-5#text-between-tool-calls), cujo texto fica vazio na configuração padrão de `display`. Uma aplicação que faz streaming desse texto para seus usuários como atualizações de progresso fica em silêncio entre as chamadas de ferramentas até definir um valor de `display` que retorne o texto. [O que há de novo no Claude Opus 5.5](https://platform.claude.com/docs/pt-BR/models/opus-5-5/whats-new-opus-5-5) ## Como ele se compara | Model | Context | Max output | Price / MTok | Latency | 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 | Slower | Adaptive (always on) | `high` | Jun 2026 | | **Claude Opus 5.5** (this model) | 1M | 128K | $4 / $20 | Moderate | 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 | Fast | Adaptive | `high` | Jun 2026 | | [Claude Haiku 5.5](https://platform.claude.com/docs/pt-BR/models/haiku-5-5/overview) | 1M | 128K | From $0.10 / $0.50 | Fastest | 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. * **Latency:** Comparative latency, relative to the current lineup, as published in the models overview. Actual latency depends on prompt length, output length, and thinking effort. * **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. ## Especificações ### Model IDs | Platform | Model ID | | :-------------------------------------------------------------------------------------------------------- | :-------------------------- | | Claude API | `claude-opus-5-5` | | [Amazon Bedrock](https://platform.claude.com/docs/pt-BR/build-with-claude/claude-in-amazon-bedrock) | `anthropic.claude-opus-5-5` | | [Google Cloud](https://platform.claude.com/docs/pt-BR/build-with-claude/claude-on-vertex-ai) | `claude-opus-5-5` | | [Microsoft Foundry](https://platform.claude.com/docs/pt-BR/build-with-claude/claude-in-microsoft-foundry) | `claude-opus-5-5` | | [Claude Platform on AWS](https://platform.claude.com/docs/pt-BR/build-with-claude/claude-platform-on-aws) | `claude-opus-5-5` | ### Pricing | Feature | Value | | :---------------------------------------------------------------------------------------- | :------------------------------- | | Input | $4 / MTok | | Output | $20 / MTok | | [5m cache write](https://platform.claude.com/docs/pt-BR/build-with-claude/prompt-caching) | $5 / MTok | | [1h cache write](https://platform.claude.com/docs/pt-BR/build-with-claude/prompt-caching) | $8 / MTok | | [Cache read](https://platform.claude.com/docs/pt-BR/build-with-claude/prompt-caching) | $0.20 / MTok | | [Batch API](https://platform.claude.com/docs/pt-BR/build-with-claude/batch-processing) | 50% discount on input and output | [Full price list](https://platform.claude.com/docs/pt-BR/about-claude/pricing) ### Capabilities | Feature | Value | | :----------------------------------------------------------------------------------------------------------------------------- | :--------------------- | | [Context window](https://platform.claude.com/docs/pt-BR/build-with-claude/context-windows) | 1M tokens | | Max output | 128K tokens | | [Max output (Batch API, beta)](https://platform.claude.com/docs/pt-BR/build-with-claude/batch-processing#extended-output-beta) | 300K tokens | | [Thinking](https://platform.claude.com/docs/pt-BR/build-with-claude/thinking) | Adaptive (always on) | | [Default effort](https://platform.claude.com/docs/pt-BR/build-with-claude/effort) | `medium` | | Comparative latency | Moderate | | Input → output | Text and images → text | | Reliable knowledge cutoff | Jun 2026 | | Training data cutoff | Jun 2026 | ### Availability | Feature | Value | | :------------------------------------------------------------------------------- | :---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | [Status](https://platform.claude.com/docs/pt-BR/about-claude/model-deprecations) | Active (latest) | | Released | September 22, 2026 | | Retirement | Not sooner than September 22, 2027 | | Platforms | Claude API, [Amazon Bedrock](https://platform.claude.com/docs/pt-BR/build-with-claude/claude-in-amazon-bedrock), [Google Cloud](https://platform.claude.com/docs/pt-BR/build-with-claude/claude-on-vertex-ai), [Microsoft Foundry](https://platform.claude.com/docs/pt-BR/build-with-claude/claude-in-microsoft-foundry), [Claude Platform on AWS](https://platform.claude.com/docs/pt-BR/build-with-claude/claude-platform-on-aws) | ## Bom saber * O "adaptive thinking" (pensamento adaptativo) está sempre ativado e não pode ser desativado. Controle a profundidade do pensamento com o [parâmetro effort](https://platform.claude.com/docs/pt-BR/build-with-claude/effort). * Na [Message Batches API](https://platform.claude.com/docs/pt-BR/build-with-claude/batch-processing#extended-output-beta), o Claude Opus 5.5 suporta até 300 mil tokens de saída com o cabeçalho beta `output-300k-2026-03-24`. * O comprimento mínimo de prompt armazenável em cache é de 512 tokens. Consulte [Cache de prompt](https://platform.claude.com/docs/pt-BR/build-with-claude/prompt-caching#cache-limitations). * Consulte limites e capacidades programaticamente com a [Models API](https://platform.claude.com/docs/pt-BR/api/models/list). ## Recursos Diferenças de comportamento e padrões de prompt específicos do Claude Opus 5.5.
