[cost\_intel] Assuming streaming reduces token costs compared to batch generation

Streaming improves time-to-first-byte but does not reduce token cost; tokens are billed identically. For high-volume latency-tolerant work, use the Batch API which offers 50% pricing discounts in exchange for 24-hour turnaround.

Journey Context:
Developers often conflate latency optimization with cost optimization. Streaming delivers tokens as they're generated, improving perceived speed, but the total token count—and therefore cost—is identical to non-streaming. In fact, streaming incurs minor connection overhead. The real cost trap is using synchronous real-time APIs for backfill, data processing, or bulk tasks. OpenAI's Batch API \(and similar offerings\) provide exactly the same model outputs at 50% reduced pricing \($5/1M → $2.50/1M for GPT-4o\) by accepting 24-hour latency. This is the only mechanism to actually reduce per-token pricing on identical model versions.
