Summary
According to a post on X by @Weyaxi, a write-up by Yağız Çalık of @aiand_ describes work presented at the SGLang Summit on reinforcement learning training across mixed hardware. The setup uses a two-node B300 trainer that receives rollouts from four chips across two vendors, including B300, H200 and AMD MI355X, connected over plain HTTP. With LoRA, each sync moves a 4 GB adapter instead of the 709 GB base model. The write-up reports that InfiniBand synced 6.5x faster than HTTP but saved under 2% of a step, and that adding a second MI355X rollout node nearly doubled output.

What happened
Yağız Çalık of @aiand_ wrote up work presented at the SGLang Summit: a two-node B300 trainer fed by rollouts from four chips across two vendors (including B300, H200 and AMD MI355X), all over plain HTTP.

Why it matters
For teams running reinforcement learning on AI accelerators, the reported figures suggest that LoRA adapter syncing over plain HTTP may be workable, since a faster InfiniBand link saved little per step. The results also point to rollout capacity as a lever, because one added node nearly doubled output in the described setup. Readers should check the full write-up for benchmark conditions, which the snippet does not show.
