Full Explanation
When streaming is enabled (stream=True), the API returns server-sent events (SSE) that deliver tokens as they are generated, rather than waiting for the complete response. This dramatically improves perceived latency for users, especially for long responses. Option A is wrong — streaming does not reduce token costs; pricing is the same. Option C is wrong — streaming doesn't affect context window limits. Option D is wrong — streaming is optional; non-streaming (batch) mode returns the complete response after generation.
