Safety framework and release disclosures

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

Framework
Preparedness Framework since 2023
Its own scale
Capability thresholds: High and Critical
Risk domains
CBRN, cyber, AI R&D
External evaluation
committed to
Commits to stop
yes: Commits to not deploying, or not continuing, until mitigations are in place.

Version 2, April 2025, is still the published version. OpenAI's Frontier Governance Framework of May 2026 sets out how it meets EU and Californian law and leaves this as its own standard. Three tracked categories at two thresholds: persuasion was dropped in 2025, and long-range autonomy and nuclear risk are research categories without thresholds. At a Critical threshold it commits to halt further development until safeguards are specified.

Energy and emissions

What OpenAI has published about the energy behind its models, and what permits and press reporting add.

Training energy or emissions Not disclosed
No energy or emissions figure for any model.
Where it trains and serves Published
Stargate sites built with Oracle and SoftBank. The first, at Abilene, Texas, runs on Oracle Cloud Infrastructure. OpenAI
What powers those sites Reported by others
Permits filed for on-site natural-gas turbines at the Abilene campus. OpenAI publishes no energy figure for any site. DCD
Energy per prompt Published
0.34 Wh for an average ChatGPT query, June 2025, stated without a method. Sam Altman
