The first framework that can post train DeepSeek V4-pro on a single-node?

SphereLab has open-sourced Orbit, a framework capable of reinforcement learning post-training of trillion-parameter models like DeepSeek V4 on a single node. The release aims to lower the hardware barrier for fine-tuning large language models, potentially enabling broader access to advanced AI customization.

We just opensourced a project called Orbit, which can RL post train trillion scale LLMs like deepseek v4. We found it pretty cool Looking forward to some comments - Tim Blog post: https://spherelab.ai/orbit/ reply
