Safety framework and release disclosures

The frontier safety framework Microsoft has published, and what it published at each release since January 2025.

Framework
Frontier Governance Framework since 2025
Its own scale
Risk levels per capability: low, medium, high, critical
Risk domains
CBRN, cyber, AI R&D, loss of control, manipulation
External evaluation
committed to
Commits to stop
yes: Commits to not deploying, or not continuing, until mitigations are in place.

Revised in February 2026 to align with the EU Code of Practice and the Californian and New York frontier AI laws, adding loss of control and harmful manipulation. Commits to pause development and deployment of a model whose risk cannot be sufficiently mitigated. Covers models in scope of those laws, and Microsoft's substantial fine-tunes of other developers' models.

Power is Epoch's estimate from imagery and permits, IT power where it states one. Confidence is Epoch's own label for each owner or user. AI Data Centers Epoch AI Licence CC-BY-4.0 Updated several times a week Retrieved , today 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.
