The rStar2-Agent framework boosts a 14B model to outperform a 671B giant, offering a path to state-of-the-art AI without ...

This similarity primarily arises from mainstream RL algorithms such as PPO/GRPO, which use gradient clipping mechanisms to ensure training stability. This mechanism smooths the model's evolutionary ...

However, behind this competition, a huge bottleneck quietly limits the speed of all players—compared to pre-training and ...

CoreWeave, Inc. (NASDAQ: CRWV), the AI Hyperscaler™, today announced a definitive agreement to acquire OpenPipe Inc, a ...

Mira Murati’s Thinking Machines Lab debuts with a $2B-backed project tackling nondeterminism in AI, aiming to deliver ...

What if the very techniques we rely on to make AI smarter are actually holding it back? A new study has sent shockwaves through the AI community by challenging the long-held belief that reinforcement ...

CoreWeave hopes the YC-backed startup will help it expand up the stack and cash in on enterprises developing AI agents.
