TogetherAI Open-Sources XoRL for Zero Train-Inference Mismatch in MoE RL

TogetherAI open-sourced XoRL, a distributed RL framework that achieves zero train-inference mismatch for large MoE models by tightly aligning computation at the kernel level. It significantly improved Wordle task performance with Qwen3.6-35B-A3B, with River API outperforming Tinker.
