From the SKILL.md

# slime: LLM Post-Training Framework for RL Scaling slime is an LLM post-training framework from Tsinghua's THUDM team, powering GLM-4.5, GLM-4.6, and GLM-4.7. It connects Megatron-LM for training with SGLang for high-throughput rollout generation. ## When to Use slime **Choose slime when you need:** - Megatron-LM native training with SGLang inference - Custom data generation workflows with flexible data buffers - Training GLM, Qwen3, DeepSeek V3, or Llama 3 models - Research-grade framework with production backing (Z.ai) **Consider alternatives when:** - You need enterprise-grade stability features → use **miles** - You want flexible backend swapping → use **verl** - You need PyTorch-native abstractions → use **torchforge** ## Key Features - **Training**: Megatron-LM with full parallelism support (TP, PP, DP, SP) - **Rollout**: SGLang-based high-throughput generation with router - **Data Buffer**: Flexible prompt management and sample storage - **Models**: GLM-4.x, Qwen3, DeepSeek V3/R1, Llama 3 ## Architecture Overview ``` ┌─────────────────────────────────────────────────────────┐ │ Data Buffer │ │ - Prompt initialization and management │ │ - Custom data generation and filtering

About this skill
What does the slime-rl-training skill do?

Provides guidance for LLM post-training with RL using slime, a Megatron+SGLang framework. Use when training GLM models, implementing custom data generation workflows, or needing tight Megatron-LM integration for RL scaling.

How do I install it?

Run `npx skills add Orchestra-Research/AI-Research-SKILLs --skill slime --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From Orchestra-Research/AI-Research-SKILLs, a repository with 11,391 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
