Together AI introduces distribution-aware speculative decoding to accelerate RL rollouts by up to 50%

Jul 11, 2026

Together AI has announced a new technique called distribution-aware speculative decoding (DAS) that can speed up reinforcement learning (RL) rollouts by up to 50% without degrading reward quality. The method addresses the bottleneck of rollout generation in RL post-training by adaptively applying speculative decoding. The announcement was made on the Together AI blog.

Why it matters: This advancement could significantly reduce the time and cost of RL post-training, making it more practical for large-scale AI model development.
