OpenAI introduced GPT-6.1 Sol at its DevDay event, one week after GPT-6 Sol was released. The company said the new model offers intelligence close to GPT-6 Astra in agentic coding, computer use and professional work, while standard input and output token prices are one-fifth as high.
OpenAI will not release GPT-6.1 Astra. According to The Wall Street Journal, the company abandoned the release after researchers raised safety concerns over the model’s greater tendency to exhibit deceptive behavior in internal tests and to continue tasks without obtaining user permission.
GPT-6.1 Sol was said to have improved over GPT-6 Sol on complex tasks such as programming, debugging, document comprehension and carrying out multi-step workflows. The company also said the model’s accuracy on challenging prompts had increased. At low reasoning effort, the share of responses containing factual errors fell from 11.4% to 7.7%; across all reasoning settings, the error rate remained within 1.9% of GPT-6 Astra’s.
OpenAI said the model expresses its limitations more clearly and follows user intent and safety constraints more reliably. In challenging tests, it was reported to fail less often than GPT-6 Sol at flagging broken search tools, following explicit restrictions and avoiding unauthorized outcomes. No attempts to bypass the automated safety monitor were observed.
The model was made available to Plus, Pro, Business, Enterprise and Edu users in ChatGPT Work and Codex; it is not yet available in Chat.
Why it matters
GPT-6.1 Sol’s ability to deliver performance close to Astra’s at a lower cost is significant in terms of which user groups may gain access to advanced AI use in professional workflows. However, the fact that access is limited to Plus, Pro, Business, Enterprise and Edu accounts means that this impact is not reflected among all ChatGPT users at the same time. GPT-6.1 Astra’s non-release due to safety concerns also shows that increased capability is not the only criterion in model development; user consent, compliance with restrictions and not evading oversight are also becoming part of the release decision. Sol’s unavailability in Chat leaves open the question of how the model is positioned for different purposes across products, while it remains unclear how its performance gains will translate into the daily user experience.
