Frontier AI developers compared

Models and compute are Epoch AI's list and estimates. Commits to stop is what each framework says, from the Frontier Safety Framework Index; card on the day counts releases since January 2025 in the Release Safety Disclosure Index. Sites and planned power are those Epoch's hub records the company as owning. A stated token volume covers whatever scope the company chose and does not compare across companies. Notable AI Models Epoch AI Licence CC-BY-4.0 Updated weekly Retrieved 2026-10-18, 10 days ago Inclusion is editorial ("notability criteria"), not exhaustive. Compute figures are frequently estimates; check the per-row confidence and notes columns before treating any value as measured. Cite Epoch AI, "Notable AI Models". https://epoch.ai/data/ai-models.

Frontier Safety Framework Index This site Licence MIT Updated quarterly Retrieved 2026-10-18, 10 days ago Data JSON CSV Our own reading of each developer's published safety framework and model cards. Every field is what the developer says about itself: these are self-assessments under self-written frameworks with no common scale and no external audit, and they are indexed here for exactly that reason. Not a ranking, and not a verification. Cite AI Safety Tracker, "Frontier Safety Framework Index". https://aisafetytracker.org/alignment/#frameworks. Retrieved 18 October 2026. Release Safety Disclosure Index This site Licence MIT Updated monthly Retrieved 2026-10-18, 10 days ago Data JSON CSV Our own reading of the system card, model card or safety report each developer published for each release Epoch AI lists from 2025, joined to Epoch's list. Every cell is what a developer says about its own model under its own framework: whether a card came out with the release, whether it reports dangerous-capability results, which government institutes it names as pre-release testers, and whether it says a risk threshold was reached. None of it is verified. A release Epoch adds after the last review is shown as awaiting review.

AI Data Centers Epoch AI Licence CC-BY-4.0 Updated several times a week Retrieved 2026-10-18, 10 days ago The largest AI sites Epoch has found, mostly in the United States. Epoch estimated in September 2026 that they hold 44% of the world's deployed AI compute, with a 90% interval of 23% to 81%. Power, compute and cost are Epoch's estimates from satellite imagery, permits and company statements; four in five IT power estimates fall within a factor of 1.4 of the true value. The owner is the owner of the chips, not necessarily of the building. Capacity after the date of retrieval is Epoch's projection. Coordinates are read from the hub's map page, which publishes them; the downloads do not. Cite Epoch AI, "AI Data Centers". https://epoch.ai/data/ai-data-centers.

AI Usage Disclosure Index This site Licence MIT Updated quarterly Retrieved 2026-10-18, 10 days ago Data 3 datasets Our own compilation of the token volumes, user counts and shares of use that companies and studies have put on the record, each linked to where it was stated. Scopes, units and token definitions differ between companies, so no two figures are comparable without the scope printed beside each. Figures known only through press reporting are marked as such. Not a market share estimate, and not a measure of any company's actual volume beyond what it chose to state. Cite AI Safety Tracker, "AI Usage Disclosure Index". https://aisafetytracker.org/usage/.
