New Artificial Analysis benchmark shows OpenAI, Anthropic, and Google locked in a three-way tie at the top

Jan 7, 2026

Artificial Analysis just released version 4.0 of its Intelligence Index, ranking AI models across multiple benchmarks. OpenAI's GPT-5.2 at its highest reasoning setting takes the top spot, with Anthropic's Claude Opus 4.5 and Google's Gemini 3 Pro close behind.

The index scores models across four equally weighted categories: Agents, Programming, Scientific Reasoning, and General. Results are less saturated this time, with top models peaking at 50 points compared to 73 in the previous version.

At the top of the cost table is GPT-5.2 (xhigh) with a total cost of $2,322, followed by Grok 4 ($1,574) and Claude 4.5 Opus ($1,510). Gemini 3 Pro Preview trails significantly behind at $988. | Image: Artificial Analysis

The updated index swaps three older tests (AIME 2025, LiveCodeBench, and MMLU-Pro) for a fresh set: AA-Omniscience checks model knowledge across 40 topics while flagging hallucinations, GDPval-AA tests models on practical tasks across 44 professions, and CritPt tackles physics research problems. Artificial Analysis says it ran all tests independently using a standardized approach, with full details available on its website.
