* **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.

## 알아두면 좋은 점

* [Message Batches API](https://platform.claude.com/docs/ko/build-with-claude/batch-processing#extended-output-beta)에서 Claude Sonnet 5는 `output-300k-2026-03-24` 베타 헤더를 사용하여 최대 300k 출력 토큰을 지원합니다.
* `temperature`, `top_p` 또는 `top_k`를 기본값이 아닌 값으로 설정하면 400 오류가 반환됩니다.
* [Models API](https://platform.claude.com/docs/ko/api/models/list)를 사용하여 한도와 기능을 프로그래밍 방식으로 조회하세요.
