SGLang(@sgl_project):Congrats to the Halo team (@whitecircle) on the launch! 🎉 SGLang powers Halo rollouts as the primary engine. It runs in an isolated serving environment, returning token IDs, logprobs, and MoE routing to the trainer, with weights synced over NCCL and generation overlapped across servers. Excited to partner with the Halo team!

Halo is not limited to supervised fine-tuning. It supports async RL and training with external environments. We are excited to partner with the @sgl_project team to make it the primary engine for rollouts.
