## Summary

OpenAI’s Head of Product, Thibaud Sottiaux, announced on X on September 6, 2026 that the new GPT‑6 Astra model’s “low” inference setting delivers higher quality and speed than the “high” setting of the previous‑generation GPT‑5.6 Sol. The official guidance recommends users of Sol who relied on the high setting switch to low or medium modes on Astra.

OpenAI also said the model includes an optimization that cuts token consumption for long‑tail tasks by up to 3‑4 times for subscription‑plan users, without sacrificing response quality. The reduction is intended to lower inference costs for power users and improve overall API and chat‑based usage efficiency.

## Key points

- GPT‑6 Astra’s low setting outperforms GPT‑5.6 Sol’s high setting, according to OpenAI.
- Token consumption for long‑tail tasks is reduced by up to 3‑4 times for subscription users.
- OpenAI advises users to downgrade from Sol’s high setting to Astra’s low or medium mode.

## Why it matters

Higher performance at lower inference effort and token savings can lower costs and speed up complex coding or data‑analysis tasks for developers and enterprises.
