distributed-llm-pretraining-torchtitan

distributed-llm-pretraining-torchtitan is a skill for Claude Code, Codex from raphaelmansuy/edgecrab. It costs 83 tokens per session (2,641 once invoked), scanned A, original, no licence file.

A PyTorch-based system for pretraining large language models across many GPUs. It supports splitting model work and training data across devices so models such as Llama or custom models can be trained at large scale.

In plain words
What is it for?
Use it to pretrain LLMs on clusters ranging from several GPUs to hundreds of GPUs, with distributed checkpoints.
Why use it?
It addresses the memory and computing limits of training a language model on one machine or GPU.

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

distributed-llm-pretraining-torchtitan 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.

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.
