Siddarth(@siddarthv66):It’s fairly well known frontier labs use value functions now, but we still don't have good open value function infra. Here's something cool from my ongoing internship @MistralAI with @laurence_ai getting value functions to work Introducing - Prime Values > Clean hackable, independent abstractions built on top of prime-rl by @PrimeIntellect > First-class asynchronous value trainer and evaluator nodes, with no trainer bottleneck > Native value warmup support > Streaming replay buffer feeds value model exploiting its greater staleness/reuse tolerance Defaults validated to match or outperform mean-baseline GRPO on both single-turn and multi-turn tasks
