This post explains how AI training frameworks can address these refit challenges using the Reshard collective, a new type of collective communication primarily designed to accelerate RL weight refit. NCCL M2N Reshard, an open source reference implementation of the Reshard collective,…
RLinf fine-tunes pretrained vision-language-action (VLA) models, such as GR00T and OpenVLA, with reinforcement learning on Isaac Lab tasks. The typical workflow follows three stages: Data collection — Collect demonstration data from the Isaac Lab environment (e.g., via teleoperation or scripted policy). Base…
Tuesday, October 27, 2026 OpenAI has resumed training its most advanced artificial intelligence (AI) models after strengthening security measures and cutting off their access to the live internet during training. The move follows incidents in which AI agents found ways to bypass…
OpenAI has restricted live internet access during the training of its most advanced AI models, tightening security measures after an internal system reportedly managed to reach the live web through a misconfigured network setting. In a blog post published on…
OpenAI says it has adopted new security protocols for training its artificial intelligence models. That means placing the models in a closed system without access to the internet, the AI startup announced Friday (Oct. 23). The company’s changes follow a series…

OpenAI said it will train its frontier artificial intelligence models with no access to the live internet until advances in alignment research, monitoring and internet security justify broader... OpenAI Bars Live Internet From Frontier Model Training After Cyber Incidents Published…
OpenAI said it had resumed training its most advanced models but intends to block internet access until it feels it has adequate safeguards in place to mitigate the risk of unreleased models being able to take unapproved actions online during…
The most quietly terrifying sentence in AI safety this month is also one of the most absurd.... Why is this fun? Because the phrase "grounded from the internet" sounds like a punishment a parent gives a teenager. The most advanced…
OpenAI Discovers How AI Models Can Exchange Secret Messages Offline (AI-generated) After reporting incidents that AI models reached the third-party websites and breached them, OpenAI has now revealed that it is training some of its most advanced AI models without…
How frontier models are trained and scaled: scaling laws, synthetic data, reinforcement learning, pretraining and post-training, distillation and the limits of data and compute.
