   Nebius reports up to 5x faster RL training steps with an auto-tuner

   AINebius reports an internal auto-tuner that optimizes training, inference, and environment execution in the reinforcement learning loop. Across 210 runs on NVIDIA B300 GPUs, all eight tested jobs improved, with steps 1.42x to 4.93x faster and a median of about 3.5x. The author quotes Nebius noting that nearly doubling inference throughput did not shorten the RL step, because sandbox execution absorbed the gain.

The trend compares only continuously observed participants, so its scope may be smaller than the current heat total. Hover or tap for hourly heat; use arrow keys with a keyboard.
