PrimeIntellect-ai/prime-rl

It addresses the challenge of training large-scale agentic RL models efficiently by providing a fully asynchronous, high-throughput framework that scales to 1000+ GPUs. It solves the complexity of managing distributed training with FSDP2, vLLM inference, and multi-node deployment, while supporting a wide range of model families including MoE and multimodal models.

Developers can build and train large-scale RL agents for tasks like software engineering (SWE), agentic environments, and multimodal reasoning. The framework supports end-to-end post-training (SFT, RL, evals), and can handle frontier models like GLM-5 with advanced features like FP8 inference, PD disaggregation, and Mooncake KV offload. The ceiling includes training 1T+ parameter MoE models on 1000+ GPUs with expert and context parallelism.
