[gotcha] Streaming locks the model into early wrong tokens because autoregressive generation cannot course-correct mid-stream

For high-stakes outputs like code or structured data, use a generate-then-stream pattern: buffer the full response server-side, validate it with syntax checks or schema compliance, then stream the validated version. For lower-stakes outputs, buffer at least the first 20 to 50 tokens before streaming to let the model establish a correct direction before the user sees output.

Journey Context:
Autoregressive models generate one token at a time each conditioned on all previous tokens. Once the model emits a wrong token early such as starting a Python code answer with JavaScript syntax the probability of continuing correctly plummets because the wrong token becomes part of the context for all subsequent tokens. Streaming makes this visible and irreversible: the user watches the model go wrong in real-time. Without streaming you can discard and retry a bad complete response before the user ever sees it. The counter-intuitive insight is that streaming which improves perceived latency simultaneously removes your ability to silently retry bad responses and makes errors more visible. The tradeoff is latency versus error visibility.
