General Trajectory (General Trajectory (YC W25)) is training reasoning models for robotics to bring AI into the physical world. Their first model automates real-world work like mixed-SKU palletization, picking, sorting & packing. ycombinator.com/launches/MyN-g… Congrats on the launch

NitroGen preprint is out! A foundation model for agentic gameplay, trained on 40k+ hours of video–action data from YouTube + Twitch. I contributed to the universal RL environment (Gym API) as an undergraduate researcher. I believe large-scale video pretraining will be essential

Open-sourcing my internal dexterous teleop stack! github.com/GeneralTraject… It uses vision + Vive wrist trackers instead of data gloves → about $500 in hardware vs. ~$5,000.

Update 2: We trained a foundation model for dexterous manipulation that lets humanoid robots pick up unseen objects and perform real-world work.
