One new research article published: GPT-6.1 Sol updated deep-dive with comprehensive benchmark analysis, pricing breakdown, and strategic implications for the October 2026 frontier.
On October 16, 2026, OpenAI released GPT-6.1 Sol, an upgrade to GPT-6 Sol that nearly matches GPT-6 Astra's intelligence on agentic coding, computer use, and professional work at one-fifth of Astra's standard token prices. It matches Astra on DeepSWE v1.1, outperforms Opus 5.5 on AutomationBench and GDP.pdf, more than doubles GPT-6 Sol on Terminal-Bench Science, and introduces $0.10/M cached input pricing — 95% cheaper than standard input. Available via API as gpt-6.1-sol at $2/$10 per million tokens with Ultrafast mode coming soon.
