The SGLang team congratulated Whitecircle on launching Halo, their RL training platform, and detailed the integration: SGLang serves as Halo's primary rollout engine, running in an isolated serving environment that returns token IDs, logprobs, and MoE routing to the trainer, with weights synced over NCCL and generation overlapped across servers.
- Halo supports more than supervised fine-tuning: async RL and training with external environments
- The two teams partnered to make SGLang the core rollout infrastructure
