FAQPage Schema
How do I run RL post-training for large language models using Megatron and SGLang?▼

Run RL post-training for large language models using slime to orchestrate structured workflows, data buffers, and rollout tooling with Megatron and SGLang. It provides pre-configured scripts to easily launch baseline experiments.

Can I use slime to train Qwen3, DeepSeek, and Llama3 models?▼

Yes, slime supports RL post-training for Qwen3, DeepSeek V3/R1, Llama3, and GLM-4.x model families. It includes pre-configured scripts to ensure robust and reproducible experiments across these architectures.

What's the best way to implement asynchronous or multi-turn GRPO training?▼

Implement asynchronous and multi-turn GRPO training using slime's structured workflows. It provides rollout orchestration and tool use configurations to manage these complex training cycles effectively.

How do I manage data prompts and reward modeling for LLM rollouts?▼

Manage data prompts and reward modeling for LLM rollouts using slime's flexible data buffer. It enforces configurable prompts and reproducibility safeguards to ensure robust experimentation.

Why do I need a data buffer for LLM reinforcement learning experiments?▼

You need a data buffer for LLM reinforcement learning to manage rollout orchestration and evaluation configurations. Slime uses this buffer to enforce reproducibility safeguards and maintain structured training workflows.
