[cost\_intel] Streaming completions can cost 10-30% more per token than batch for the same content

Use streaming only when low time-to-first-token is user-visible; for backend/async pipelines, use batch or non-streaming requests. Model the real cost as \(tokens × rate\) \+ \(per-request overhead × request\_count\), and set stream=True only when latency dominates billable wall-clock time.

Journey Context:
Streaming is priced per-token, but it often prevents response compression, increases connection overhead, and makes retries more expensive because partial streams must be discarded. In backend batch jobs, non-streaming lets providers optimize and often offers separate batch pricing \(OpenAI Batch API is 50% cheaper\). The 'always stream' default in many SDKs is a trap: it feels free but inflates effective token cost and complicates observability. Measure end-to-end dollars per useful output, not latency alone.
