OpenAI launched its new GPT-6.1 Sol on Tuesday as the successor to its recently released GPT-6 Sol AI model. The new model was introduced during the OpenAI Dev Day 2026 event on Tuesday, along with the ChatGPT Dots agent and its new collaborative platform called ChatGPT Space. OpenAI claims that its latest GPT-6.1 AI model delivers enhancements on multiple fronts over its predecessor, including agentic coding, computer use, and professional work. It is claimed to “nearly match” GPT-6 Astra's capabilities, while being notably more cost-efficient. The Sam Altman-led AI giant also claims that the GPT-6.1 Sol outperformed Anthropic's Opus 5.5 with fallbacks.
