Alphabet's Google released Gemini 3.1 Pro in preview as an update to its benchmark AI model. The new iteration reached the top of the Artificial Analysis Intelligence Index. It outperformed competitors including Anthropic's Claude Opus 4.6 on several key evaluation parameters.
Analysis indicates Gemini 3.1 Pro runs at less than half the cost of comparable models from OpenAI and Anthropic. This efficiency highlights significant operational gains for Google's AI infrastructure.
This release follows the launch of Gemini 3 in November. The previous iteration improved Google's standing in the AI sector and contributed to positive movement in the company's stock performance.
