A developer builds a chat application on a large language model API and notices latency spikes when responses are long. Which change most directly improves time-to-first-token without changing the model?

Short Explanation and Infographic
Here's the deal — streaming doesn't make the model smarter, but users see the first tokens sooner. Long complete-buffer waits feel slower even if total generation time is similar.

Full Explanation
Streaming improves perceived latency by delivering tokens as they are generated, reducing time-to-first-token from the client's perspective. Raising max output tokens can increase total generation time. Disabling authentication is insecure and unrelated. Image-only stores do not address chat latency. Production apps should also monitor TTFT and total latency separately and size concurrency for the provider's rate limits.
