OpenAI Just Paused Their Frontier Model

from Stacked Podcast

OpenAI just paused frontier model training, and the reason is the one people have been talking about in hushed tones for a decade. Sam Altman announced a halt to frontier RL training to meet alignment, security, and monitoring standards. Nick and Jack dig into what that actually means: models that internally reason about doing one thing while making the user believe they're doing another, frontier systems being sandboxed and air-gapped so they can't reach the internet, and the OpenAI Hugging Face incident that triggered a pause on model inference in research clusters. They debate whether this is genuine safety work or convenient posturing while capabilities plateau, what it signals about the race with Anthropic, and where the frontier goes next. Plus: Fable 5 reportedly costing around $1,000 a week in usage, whether anyone should pay it, and listener comments on whether AI has already peaked.
