Epoch AI

Epoch AI has established itself as one of the most credible independent voices tracking AI progress, and its nonprofit, donor-funded structure gives it a degree of neutrality that vendor-run leaderboards can't match. FrontierMath is the standout product: a genuinely difficult benchmark of unpublished, expert-level math problems that exposed how far frontier models still are from real mathematical reasoning when top models initially solved under 2% of problems, a useful corrective to inflated benchmark claims elsewhere. The Epoch Capabilities Index and AI Benchmarking Hub add a more holistic view of model capability over time, while its open data explorers on training compute, AI data centers, chip sales, and company financials are a genuinely unique resource, drawing on satellite imagery and permit data that few other organizations bother to compile. Everything is free and much of it openly licensed, which is remarkable given the research quality on display. This isn't a polished consumer product, and navigating the breadth of datasets and benchmarks takes some familiarity with the field, but for researchers, journalists, and policymakers who need rigorous, independent AI trend data, Epoch AI is close to unmatched.
