Benchmark profile
Abstraction and Reasoning Corpus for AGI v2 (ARC-AGI-2)
A benchmark measuring fluid intelligence and novel abstract reasoning through visual grid puzzles. Models must identify patterns in input-output pairs and generate the correct output for unseen inputs. Considered the hardest public reasoning benchmark — average individual human performance is 66%.
Data verifiedGPT-5.5 leads the ARC-AGI-2 leaderboard on BenchLM's July 2026 update with 85%, ahead of GPT-5.4 Pro (83.3%) and Gemini 3.1 Pro (77.1%), across 12 tracked models.

Expert-level — hardest public reasoning benchmark
ARC-AGI-2 extends the original ARC benchmark with harder puzzles designed to test genuine fluid intelligence. Four major AI labs (Anthropic, Google, OpenAI, xAI) now report their model performance on this benchmark. Average individual human performance is 66%, the human panel completion rate is 100%, and the grand prize threshold is greater than 85%. Top frontier models reach 75-85 in BenchLM's tracked data, making it one of the few benchmarks that still separates current reasoning systems.
