VibeThinker-1.5B: Compact AI Model Achieves High Performance At Scale
8 days ago 高效码农Exploring VibeThinker-1.5B: A Compact AI Model That Thinks Like the Big Ones Have you ever wondered if a small AI model could tackle tough math problems or write code as well as those massive ones that take up server farms? It sounds counterintuitive—after all, the tech world often pushes for bigger models with billions or trillions of parameters to get better results. But what if the key isn’t just size, but smarter training? That’s where VibeThinker-1.5B comes in. This 1.5 billion-parameter model, developed by a team at Sina Weibo, flips the script. It uses a fresh approach to post-training that …
DreamGym: Revolutionizing Synthetic RL for AI Agents with Synthesized Trajectories – Ultimate Guide
9 days ago 高效码农Scaling Agent Learning Through Experience Synthesis: An Introduction to DreamGym What Is DreamGym and Why Does It Matter for AI Agents? DreamGym is a groundbreaking framework that makes reinforcement learning (RL) for large language model (LLM) agents more practical by creating synthetic experiences instead of relying on expensive real-world interactions. At its core, it addresses the biggest hurdles in training AI agents—like high costs, limited task variety, unreliable feedback, and complex setups—by using a reasoning-based model to generate diverse, high-quality data. This approach allows agents to learn effectively in a controlled, scalable way, leading to better performance in real applications …
