Reinforcement Learning in the era of LLMs requires scalable, distributed systems to push the boundaries of reasoning and alignment. Today - we release Atropos - our RL environments framework.
https://github.com/NousResearch/Atropos…
Atropos is a rollout framework for reinforcement learning with foundation models that supports complex and diverse environments for advancing the capabilities of foundation models.
This is the first of three parts of our overall Reinforcement Learning Framework for scalable, distributed RL - the next two are an adapted inference engine and a GRPO trainer.
In Greek mythology, Atropos was the eldest of the three Fates. While her sisters spun and measured the threads of mortal lives, Atropos alone held the shears that would cut these threads, determining the final destiny of each soul. Just as Atropos guided souls to their ultimate fate, this system guides language models toward their optimal potential through reinforcement learning.
