Measurement window, samples and methodology
The fleet reference is the median of published model medians, not a request-weighted result. Prompt lengths, reasoning settings and traffic differ between models.
Gemini 3.7 Flash: Measured on Borg: SearchAtlas AI Gateway production request logs. 30-day window ending 2026-10-08; 2106593 requests. Minimum 100 samples per published request metric.
Gemini 3.8 Flash: Measured on Borg: SearchAtlas AI Gateway production request logs. 30-day window ending 2026-10-08; 92815 requests. Minimum 100 samples per published request metric.
Completion speed covers the whole turn including queueing and reasoning time; it is not a streaming tokens-per-second figure.
- Time to first token (gateway proxy): time until the first streamed response event reaches the gateway; our closest available measure of time to first token
- Tokens per second (end to end): tokens per second, end to end: provider-reported output tokens divided by the whole turn's elapsed time, including queueing and reasoning; not a streaming per-token rate
How to choose
Gemini 3.7 Flash is listed for video-informed agent workflows, whereas Gemini 3.8 Flash is listed for long-horizon coding agents. Choosing between Gemini 3.7 Flash and Gemini 3.8 Flash requires checking published specifications against observed Borg traffic for your workflow.
