GPT-6.1 Sol is an upgrade to GPT-6 Sol from OpenAI, positioned below the flagship GPT-6 Astra in the GPT-6 series. It delivers near-Astra intelligence for agentic coding, computer use, document-heavy professional work, and scientific research at approximately one-fifth of Astra's cost. It offers substantial improvements over GPT-6 Sol across complex professional tasks, from writing and debugging code to understanding documents and executing multi-step business workflows. GPT-6.1 Sol also shows strong alignment improvements, with lower failure rates on transparency, safety constraints, and unauthorized agentic actions compared to its predecessor.
