The Artificial Analysis Intelligence Index is a composite benchmark published by Artificial Analysis, an independent AI benchmarking company. It combines results from a set of evaluations covering areas such as reasoning and knowledge, agentic coding and terminal use, agentic knowledge work, scientific research workflows, long-context reasoning and hallucination rate. Version 5 is the latest iteration referenced by creators, with models ranked by a single aggregate score.
According to a YouTube creator's summary, Gemini 4 Carbon ranks first on this version with a score of 59, ahead of Claude Opus 5.5 at 58 and GPT-6 Astra at 57. The site also reports related measures, including cost per task, time per task, a Coding Agent Index, a Cyber Index and a Decision Index, plus capability breakdowns by domain such as finance, legal, healthcare and engineering. The details of the v5 methodology were not included in the provided page text.
The index is viewed as charts and leaderboards on the Artificial Analysis website, which also offers model and API provider comparisons on speed, latency and price. Results are published by the vendor, so users depend on its testing choices and update schedule.
