Smeltcore - Which AI models actually run on your GPU

Hi Product Hunt 👋 Every time I wanted to run a new open model locally I hit the same wall: "will this actually fit on my GPU?" The real numbers were out there — but scattered across Reddit threads, blog posts and GitHub issues, half of them untested. Mostly you'd just get vendor marketing, guesses, or "just buy a 4090." So I built Smeltcore: those numbers pulled into one place, each linked to its source and sanity-checked. Pick your GPU (RTX 3060 → 4090, or Apple Silicon) and see every model it can run — with real speed and peak-VRAM numbers and a plain verdict: runs, tight fit, or won't fit. 84 models, 27 GPUs, 800+ step-by-step install recipes for llama.cpp, Ollama, ComfyUI and MLX. Free, no signup, CC BY-SA. No invented numbers. Every benchmark links to its source, "doesn't fit" is a first-class answer, and community submissions go through a review gate. It started as a spreadsheet for myself and turned into this. Would love your feedback — especially which model × GPU pairs you're missing. And if you've benchmarked something, there's a /contribute form 🙏
