Colocated async RL gains steam as observers speculate k3 uses it too
stochasticchasm · x · 2026-09-11
A technical observer notes that colocated asynchronous RL is becoming an increasingly popular training-infrastructure pattern, speculating that k3 follows the same approach.
- The author had assumed frontier labs were already doing this
- They guess that a focus on batch invariance plus synchronous training explains the emphasis on batch invariance in v4
- Switching to colocated async RL could yield significant throughput gains
Unofficial speculation about frontier lab training infrastructure, shared for technical discussion.
