My stream arrives all at once instead of word by word. Why?

The Model API sends events as they're produced, so all-at-once output is almost always buffering on your side:

• cURL: add -N.
• Reverse proxies: turn off response buffering for that route.
• Web frameworks: use a streaming response type and flush after each write.
• Your code: make sure you read the stream as it arrives (for chunk in stream), not after collecting it.
• Check you actually sent "stream": true.

On Max and Heavy, the first visible text can take longer because the model reasons first; print reasoning_content too to see activity.

• Keep keys on your server, never in a browser or mobile app. Why
