Wait times kill your user experience. Users hate staring at a spinner for seconds. Streaming sends words one by one. Your users see text in milliseconds.

Use the text_stream helper for a simple setup.

Need the final details? Use get_final_message(). It gives you the stop reason and token usage. You do not need to count tokens yourself.

Build a professional backend with these steps:

• Use AsyncAnthropic for web servers. It keeps your app responsive.
• Use FastAPI StreamingResponse to send data to the browser.
• Set X-Accel-Buffering to no. This stops Nginx from buffering the stream.
• Catch APIConnectionError and RateLimitError to prevent crashes.

Stop the stream if a client disconnects. This saves you money on output tokens.

Streaming does not change the price. You pay for the same number of tokens.
