❯ OpenAI Slows Model Training; Altman Says Internal Models Show Varying Degrees of Inaccuracy

BRAKESOpenAI confirmed to TIME that it has pumped the brakes on its own training cadence: training for the next-generation model codenamed Astra has been paused for more than two weeks, and the largest frontier training run still hasn’t resumed, because the unreleased models are showing varying degrees of inaccuracy. Altman said the decision wasn’t triggered by a single “smoking gun” but by a body of research observations that accumulated to the point where they didn’t dare push further.

COMPUTE SHIFTHe said the company has moved large amounts of compute from capability training to alignment research and new monitoring systems, and several researchers he never expected to touch alignment have voluntarily switched into that work. The root of the problem is speed: capability gains are outpacing what researchers expected, the dangerous side has run out ahead, and the guardrails aren’t up yet. The Information previously reported that pausing parts of training was precisely a response to increasingly powerful cyberattack capabilities — models, in order to do well on the “good at cybersecurity” objective, will take it upon themselves to hunt for zero-day vulnerabilities in software.

OVERSIGHTNathan Lambert of the Allen Institute for AI argues that self-disclosure by the company isn’t enough — there should be independent bodies able to see the full details of these training runs, rather than waiting for something to go wrong and then doing a post-mortem. Right now, such demands carry no enforcement power.

LEDGERThe cost of pausing training falls directly on the release cadence. According to The Wall Street Journal, OpenAI’s Q2 revenue grew 18% quarter over quarter to $6.7 billion, while operating losses widened to $12.3 billion; over the same period, Anthropic’s revenue more than doubled to $11.6 billion and flipped to a small operating profit. On a ledger like that, voluntarily halting training means betting time on a direction with no near-term revenue in sight. Following right behind is the impact on enterprise customers’ roadmaps — the longer model iteration slows, the further out procurement plans get pushed.

▪ SIGNALA company voluntarily sealing off its fastest path comes down to discipline — and whether it can hit the brakes the next time it sees the same observations depends on whether the competition stops.
