Rollouts Not Always Bottleneck in LLM and Robot Training
carlosdponx · x · 2026-07-05
In discussing training bottlenecks, carlosdponx points out that 'bottleneck' needs more specific definition: when training LLMs or robot policies in simulation, rollouts are often a key bottleneck, but exceptions exist. He cites @jsuarez's PufferLib work as a counterexample, showing rollouts are not always the bottleneck.
