⬤ OpenAI just extended its lead in AI benchmarking. GPT-5.1 now sits at the top of the Artificial Analysis Intelligence Index with a score of 70 points under high reasoning effort—two points ahead of GPT-5's 68. The index chart shows GPT-5.1 leading a packed field of competing large language models.
⬤ GPT-5.1 is a minor version bump over GPT-5, with the biggest improvement showing up on TerminalBench—a test focused on agentic coding and terminal use. GPT-5.1 jumped 12 percentage points on that benchmark, which pushed its overall index score up by two points. Worth noting: when using minimal reasoning, GPT-5.1 showed no intelligence gains compared to GPT-5.
⬤ OpenAI also tweaked how the model interacts. GPT-5.1 has a warmer default personality, better tone controls, and follows system prompts and custom instructions more closely. On the efficiency side, GPT-5.1 used 81 million output tokens to complete the Intelligence Index tests—down from 85 million for GPT-5. That brought the total test cost to $859 versus $913 for GPT-5, even though pricing remains the same.
⬤ For anyone tracking the AI race, GPT-5.1's performance offers a clear comparison point. The higher score, targeted coding improvements, and stable pricing show OpenAI is refining its flagship model without raising costs—key factors for competitiveness and future enterprise adoption.
