Overview

Free tool — ThunderKittens. High-performance GPU kernel primitives for fast attention and matmul workflows used by LLM stacks

What this tool does

Reach for "ThunderKittens" whenever you need a reliable tool for real work across ChatGPT, Claude, Gemini, and Cursor. High-performance GPU kernel primitives for fast attention and matmul workflows used by LLM stacks On OpenRuna it sits inside a connected graph of related tools, tools, and datasets, so branching into adjacent resources is one click away. Copy it into your assistant of choice and sharpen the result with a couple of follow-up turns.

Use cases

  • Fork it as a baseline and layer in your own project context, constraints, and examples.
  • Keep it in a shared library as the canonical version of this tool for your organisation.
  • Combine it with related tools and prompts in the same OpenRuna category to build an end-to-end workflow.
  • Reach for it during planning or review sessions when you want consistent, AI-assisted structure.

Example output

Ask the model to apply "ThunderKittens" to your scenario and it returns a structured answer — clear sections, actionable steps, and assumptions stated upfront — ready to paste into docs, tickets, or code comments. A short follow-up turn usually tightens the result to exactly what you need.

Tips by platform

Claude

In Claude, paste the full tool as your first message or add it to Project instructions, then ask Claude to confirm assumptions before it executes. For longer tools, iterate inside the artifact panel.

ChatGPT

ChatGPT responds well when you paste this tool and immediately give one concrete example of your input. Use a reasoning-capable model for multi-step work.

Cursor

Add this tool to your Cursor rules and invoke it from Agent mode for repeatable results. Link back to its OpenRuna page in the rule so the source stays discoverable.
