September 29, 2026 · High importance · model
Editorial Analysis

OpenAI released GPT-6.1 Sol as an upgrade delivering near-Astra performance on agentic coding, computer use, and professional work at one-fifth of Astra's standard token prices ($2 input / $10 output per million tokens, with cached input at $0.10). The model is available in the API, ChatGPT Work, and Codex for Plus, Pro, Business, Enterprise, and Edu users. This expands access to high-capability models at substantially lower cost for complex workflows.
