Section 1
The premise
Streaming feels fast but exposes new failure modes: dropped connections, partial JSON, mid-message errors. Plan for them.
What AI does well here
- Render tokens incrementally as they arrive.
- Buffer until a parser can validate (for structured output).
What AI cannot do
- Recover a stream that the upstream cancelled mid-token.
- Pretend partial JSON is complete.
