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.
gpt-oss-120b: Measured on Borg: SearchAtlas AI Gateway production request logs. 30-day window ending 2026-10-08; 93142 requests. Minimum 100 samples per published request metric.
Kimi K2.7 Code: Measured on Borg: SearchAtlas AI Gateway production request logs. 30-day window ending 2026-10-08; 2583 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
gpt-oss-120b is listed for private self-hosted reasoning, whereas Kimi K2.7 Code is listed for multi-file coding with iterative test runs. Choosing between gpt-oss-120b and Kimi K2.7 Code requires checking published specifications against observed Borg traffic for your workflow.
