Summary
At DevDay 2026, OpenAI launched GPT-6.1 Sol, an upgrade to GPT-6 Sol. According to the company, it nearly matches GPT-6 Astra on agentic coding, computer use, and professional work at about one-fifth of Astra's standard token prices. API pricing is $2 per million input tokens, $0.10 for cached input, and $10 per million output tokens, and the model is available immediately in ChatGPT Work and Codex for Plus, Pro, Business, Enterprise, and Edu users. Benchmark figures — matching Astra on DeepSWE v1.1 or averaging $5.47 per task on Terminal-Bench Science 0.1 — all come from OpenAI's own evaluations.
Why it matters for our work
Cutting the cost of near-frontier agent models by roughly 80 percent changes the economics of document-heavy workflows, multi-step automation, and code-driven research that run at volume. The performance claims are the vendor's own, so real-world validation still matters.
