 The [Python](https://github.com/anthropics/anthropic-sdk-python) and [TypeScript](https://github.com/anthropics/anthropic-sdk-typescript) SDKs offer multiple ways of streaming. The [PHP](https://github.com/anthropics/anthropic-sdk-php) SDK provides streaming via `createStream()`. The Python SDK allows both sync and async streams. See the documentation in each SDK for details.

 If you don't need to process text as it arrives, the SDKs provide a way to use streaming under the hood while returning the complete `Message` object, identical to what `.create()` returns. This is especially useful for requests with large `max_tokens` values, where the SDKs require streaming to avoid HTTP timeouts.
