Measured on Borg

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.

The fleet reference is the median of published model medians, not a request-weighted result. Prompt lengths, reasoning settings and traffic differ between models.

Borg Fusion Coding: Measured on Borg: SearchAtlas AI Gateway production request logs. 30-day window ending 2026-10-08; 0 requests. Minimum 100 samples per published request metric.

GPT-6 Astra: Measured on Borg: SearchAtlas AI Gateway production request logs. 30-day window ending 2026-10-08; 20969 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

Borg Fusion Coding is listed for multi-step coding work, whereas GPT-6 Astra is listed for hard coding assignments. Choosing between Borg Fusion Coding and GPT-6 Astra requires checking published specifications against observed Borg traffic for your workflow.
