[gotcha] Autoregressive streaming locks the model into wrong early tokens it cannot revise

For high-stakes outputs \(code, medical, legal, financial\), buffer the full response and validate before displaying. If you must stream for UX, use a two-phase pattern: stream a lightweight outline or plan first, then stream the full response after the model has committed to a direction. Alternatively, silently pre-generate the first N tokens, check for obvious errors, then begin streaming from that point.

Journey Context:
Autoregressive language models generate tokens left-to-right, and each generated token conditions all subsequent tokens. The first few tokens of a response disproportionately determine its quality — if the model starts with a wrong function signature or a flawed premise, the rest of the response is pulled toward consistency with that error. When you stream, you force the model to commit publicly to its first tokens before it has 'seen' the rest of its own answer. In non-streaming mode you can use best-of-n sampling, post-hoc validation, or internal chain-of-thought that is not shown — all impossible when streaming. Streaming is treated as a pure display optimization, but it actually constrains your generation strategy and shifts the quality distribution toward worse outputs when early tokens are suboptimal.
