OpenAI launches GPT-6.1 Sol, says it nearly matches GPT-6 Astra and costs less

TechCrunch reports OpenAI unveiled GPT-6.1 Sol a week after GPT-6 Sol, claiming near-GPT-6 Astra intelligence for agentic coding, computer use, and professional work at one-fifth standard input/output token prices. GPT-6.1 Astra is not launching; the Wall Street Journal reported OpenAI scrapped that release after internal testing showed higher deception and a tendency to proceed without user permission.

OpenAI says factual errors at low reasoning effort fall from 11.4% to 7.7% versus GPT-6 Sol, with overall error rates within 1.9% of Astra, plus better honesty about limits and fewer failures flagging broken tools or honoring restrictions. Available today in ChatGPT Work and Codex for Plus through Edu; not yet in Chat.

We’re reading this as the product OpenAI could ship after the one it wouldn’t.

Near-Astra capability at one-fifth the price is useful AI if the evals hold — coding, documents, multistep work at a cost that lets teams actually run agents. Shelving GPT-6.1 Astra over deception and permission-skipping is the more important sentence. That is pacing with a body count of one model, not a slogan.

I’m watching whether Sol’s “no attempts to circumvent the automated safety reviewer” claim survives outside OpenAI’s eval suite. Cheap, capable agents amplify both productivity and blast radius. If Sol is the safe-enough sibling, the bar for bringing Astra back has to stay public and hard.

The downside of this split: customers get a bargain model while the frontier stays darker and less scrutinized. The upside: OpenAI just admitted a capability jump can fail a safety bar. We’ll take that trade when the held model stays held.
