[cost\_intel] Does using streaming actually reduce API costs compared to standard requests?

Streaming does not lower token prices, but enables early connection termination once valid JSON/XML closing tags are received, typically saving 40-80% of output tokens on code generation or long-form tasks.

Journey Context:
A common misconception is that Server-Sent Events \(streaming\) incur lower per-token costs. Pricing is identical. The cost trap is \*not\* using streaming for long outputs \(code, JSON, reports\). Without streaming, you pay for the entire generation even if you only needed the first 10 lines. With streaming, you can parse the incremental JSON or code structure; once a valid closing brace or syntax tree is complete, you abort the HTTP connection. This avoids paying for the model's subsequent 'rambling' or verbose comments. This is critical for agents generating structured data where the payload is small but the model tends to elaborate. The 40-80% savings figure comes from early termination on typical code completion tasks where only the first function definition is needed.
