pytorch-fsdp

pytorch-fsdp is a skill for Claude Code, Codex from nobodyohm-web/Thot. It costs 17 tokens per session (522 once invoked), scanned A, a copy of pytorch-fsdp, MIT.

A PyTorch tool that splits a large model across devices by dividing its data, parameters, and computation. This lets models that are too large for one device be trained across several devices.

In plain words
What is it for?
Use it when developing or debugging fully sharded distributed training, including model wrapping, checkpoints, sharding strategies, and mixed-precision training.
Why use it?
It reduces the memory needed on each device, helping you train larger models without copying the complete model everywhere.

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

pytorch-fsdp 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 6d ago.

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.

Origin

This is a copy

100% identical to pytorch-fsdp — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Pytorch-Fsdp Skill

Assistance with pytorch-fsdp development, generated from official documentation.

When to Use This Skill

This skill should be triggered when:

  • Working with pytorch-fsdp
  • Asking about pytorch-fsdp features or APIs
  • Implementing pytorch-fsdp solutions
  • Debugging pytorch-fsdp code
  • Learning pytorch-fsdp best practices

Quick Reference

The full common-patterns catalog (~157k chars of runnable FSDP snippets) lives in references/common-patterns.md — load it with read_file when you need wrapping, sharding-strategy, checkpoint, or mixed-precision examples. Start there rather than reconstructing FSDP incantations from memory.

Reference Files

This skill includes comprehensive documentation in references/:

  • other.md - Other documentation

Use view to read specific reference files when detailed information is needed.

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.
