LLM post-training used to mean fine-tuning to a downstream task Robotics has been stuck in this setting, needing task-specific fine-tuning for best performance π07 changes this: It works out of the box & outperforms fine-tuned specialists Details: pi.website/pi07

Very happy to start sharing our work at Pi 🤖❤️ - a 3B pre-trained generalist model trained on 8+ robot platforms - a post-training recipe that allows robots to do dexterous, long-horizon tasks physicalintelligence.company/blog/pi0 What's exciting isn't laundry, but the recipe- a short 🧵

Disappointed with your ICLR paper being rejected? Ten years ago today, Sergey and I finished training some of the first end-to-end neutral nets for robot control 🤖 We submitted the paper to RSS on January 23, 2015. It was rejected for being "incremental" and "unlikely to have

LLMs like ChatGPT are becoming more fluent – how can we detect if something was written by a language model or a human? We developed DetectGPT: a method for detecting if a passage was written by a particular language model.

In light of tremendous AI advances & recent calls for pauses on AGI research, I've decided to pivot our lab's direction. Going forward, we’ll focus entirely on certain real-world applications (see thread 🧵 for details). It was a hard decision but I'm excited for our future work
