307 AI models ranked on CritPt. Each row shows the model’s score next to its cheapest API price per 1M tokens where it has one, so you can weigh quality against cost.
Top model today
GPT-5.6 Sol (OpenAI) leads at 32%, from $5.00 per 1M input.
Each labelled name links to that model’s page. Curated to the cost-efficiency frontier, top scorers and cheapest so labels stay readable; the full field is in the leaderboard table below (and via “select all”). Reasoning models (extended “thinking” before answering) carry a ring around the dot.
Prices are on-demand list rates. Enterprise commitments can be materially lower. Cost per task uses best-effort token usage.
Frequently asked questions
What is the CritPt benchmark?
CritPt (Complex Research using Integrated Thinking, Physics Test) is a frontier physics benchmark of 71 unpublished, research-level challenges across 12 subdisciplines, created by more than 50 active physicists. Scored on accuracy in guess-resistant formats (numeric arrays, symbolic expressions, code), where the best current models solve only single-digit percentages unaided.
Which AI model scores highest on CritPt?
GPT-5.6 Sol (OpenAI) leads with 32%, from $5.00 per 1M input tokens.
How many models are ranked on CritPt?
307 models carry a CritPt score. Scores come from Artificial Analysis; where a model has a live API price it is verified against LiteLLM and OpenRouter, and models with no current price are listed without one.
