GPT-6.1 Sol

GPT-6.1 Sol came out at OpenAI’s DevDay on 29 September 2026, a week after GPT-6 Sol and at the same price. OpenAI says it matches GPT-6 Astra on the DeepSWE coding test at about a fifth of the cost, and lands within about two points of Astra on OSWorld, the computer-use test, at roughly a seventh of the cost per task.

It is the GPT to pick for production agents that need to be both good and affordable: coding, operating software, building documents and spreadsheets. It always reasons a little — the lowest setting is low — and OpenAI says it makes a factual error in about a third fewer answers than GPT-6 Sol at that setting.

For scale: 1,000 requests of about 3,000 tokens in and 1,000 out cost $18.40 — a long prompt and a page of answer each. Every rate is published and stays the same from one request to the next. See every model.
