Metrics are not directly comparable to vendor benchmark claims. Models served different requests; this is observed gateway traffic, not a controlled head-to-head test.

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.
Grok 4.3: Measured on Borg: SearchAtlas AI Gateway production request logs. 30-day window ending 2026-10-08; 87770 requests. Minimum 100 samples per published request metric.
Grok 4.7: Measured on Borg: SearchAtlas AI Gateway production request logs. 30-day window ending 2026-10-08; 1681 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
Grok 4.3 is listed for high-volume instruction-following tasks, whereas Grok 4.7 is listed for long-running agentic coding. Choosing between Grok 4.3 and Grok 4.7 requires checking published specifications against observed Borg traffic for your workflow.
