pytorch

pytorch is a skill for Claude Code, Codex from G1Joshi/Agent-Skills. It costs 17 tokens per session (309 once invoked), scanned A, original, MIT.

A guide to PyTorch, a Python framework for building and training neural networks, which are computer models that learn from data.

In plain words
What is it for?
Use it for AI research, neural-network training, model compilation, attention-based models, and managing computation across devices or multiple GPUs.
Why use it?
It provides a common way to experiment with models, inspect them during execution, and prepare them for faster production use.

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 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 8d 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.

What it actually says

PyTorch

PyTorch is the dominant framework for research and production AI. v2.5 (2025) solidifies torch.compile and introduces FlexAttention.

When to Use

  • Research: 99% of new papers (Arxiv) use PyTorch.
  • Production: Recommended for almost all new DL projects.
  • Performance: torch.compile provides C++ level speed with Python ease.

Core Concepts

torch.compile

Just-in-Time (JIT) compilation of your model. model = torch.compile(model) -> 2x speedup.

Dynamic Graphs (Eager Mode)

Debug line-by-line (print(tensor.shape) works).

Fabric / Lightning

High-level wrappers to simplify training loops and multi-GPU setup.

Best Practices (2025)

Do:

  • Use torch.compile: It is now stable and essential for H100 performance.
  • Use FlashAttention: Use the scaled dot product attention (SDPA) kernel for Transformers.
  • Use PyTorch 2.x: PyTorch 1.x is legacy.

Don't:

  • Don't code .cuda() manually: Use .to(device) or Fabric to handle device placement.

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.

pytorch is a skill published in the GitHub repository G1Joshi/Agent-Skills (12 stars, last pushed 6mo ago), licensed MIT. It adds 17 tokens to every session and 309 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
