The premise
Streaming gives the perception of speed and engagement. Block responses make validation, parsing, and rendering simpler.
What AI does well here
- Stream tokens as generated for visible progress.
- Return blocks for structured output requiring parsing.
- Cancel mid-stream to save tokens when user navigates away.
- Render markdown progressively in chat UIs.
What AI cannot do
- Validate JSON mid-stream before completion.
- Recover gracefully from mid-stream errors in all UIs.
