OpenAI weighs slowing cutting-edge AI, Altman tells staff

NVIDIA AI researchers walk through how the final Nemotron model checkpoints were built via post-training to boost model intelligence and enable agentic capabilities. The session covers the tools used and how the data pipeline was structured.

In a post on X, OpenAI's Adam Majmudar argues outsiders reasonably read the past two weeks as an orchestrated sequence of AI announcements, while those inside see a different pace of progress.

r/ExperiencedDevs thread asks when software engineering will get a counterpart to "A Severe Misalignment of AI in Mathematics," linking mathandai.org. The post drew no substantive detail beyond the comparison itself.

Matthew Berman's video examines DeepSeek's performance on a Rubik's Cube test, where the model fails the task.

ARC Prize says ARC-AGI-4 will benchmark autonomous open-ended innovation, keeping the effort open-source as a shared research target. The announcement notes humans still significantly outperform AI at open-ended tasks.

A Reddit user released smolbenchmark, a leaderboard for models that fit in 8GB of memory, ranked by decode speed, tokens per joule, and heat. It targets tablets and other low-power local hardware rather than GPU servers.
