torchforge-rl-training

torchforge-rl-training is a skill for Claude Code, Codex from davila7/claude-code-templates. It costs 49 tokens per session (2,611 once invoked), scanned A, original, MIT.

A PyTorch library for training language models with reinforcement learning, where model behavior improves from reward signals. It keeps the training algorithms separate from the systems that distribute work across GPUs.

In plain words
What is it for?
Use it to test algorithms such as GRPO, DAPO, or SAPO and train agent-like language models from one GPU to large distributed setups.
Why use it?
It reduces the infrastructure code needed to experiment with different reinforcement-learning methods and scale training.

About the project

Claude Code Templates is a command-line tool and catalogue for configuring Anthropic’s Claude Code with agents, commands, settings, hooks, integrations, skills, and project templates. Developers use it to browse and install reusable components for their coding workflows. The catalogue includes many of these Claude Code components.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

torchforge-rl-training scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

torchforge: PyTorch-Native Agentic RL Library

torchforge is Meta's PyTorch-native RL library that separates infrastructure concerns from algorithm concerns. It enables rapid RL research by letting you focus on algorithms while handling distributed training, inference, and weight sync automatically.

When to Use torchforge

Choose torchforge when you need:

  • Clean separation between RL algorithms and infrastructure
  • PyTorch-native abstractions (no Ray dependency)
  • Easy algorithm experimentation (GRPO, DAPO, SAPO in ~100 lines)
  • Scalable training with Monarch actor system
  • Integration with TorchTitan for model parallelism

Consider alternatives when:

  • You need production-ready stability → use miles or verl
  • You want Megatron-native training → use slime
  • torchforge is experimental and APIs may change

Key Features

  • Algorithm isolation: Implement RL algorithms without touching infrastructure
  • Scalability: From single GPU to thousands via Monarch
  • Modern stack: TorchTitan (training), vLLM (inference), TorchStore (sync)
  • Loss functions: GRPO, DAPO, CISPO, GSPO, SAPO built-in

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
