About
Before you download gigabytes of model weights, know whether they'll actually fit. VRAMFit tells you the largest local large language model you can run on your hardware — whether that's an NVIDIA GPU's VRAM or the unified memory on an Apple Silicon Mac. Set your memory, pick a quantization, and get a clear, instant answer. Built for people who run models locally: llama.cpp, Ollama, LM Studio, and anyone deciding what GPU to buy next. WHAT IT DOES • Enter your VRAM (or Apple Silicon RAM) and instantly see what fits • Accounts for quantization — from full precision down to 4-bit and FP4 • Factors in context length and KV cache, the memory costs people usually forget • Switches between discrete GPU and Apple Silicon unified-memory math • Ships with a 2026 catalog of popular open models, sized for you FREE • The full calculator, with quantization, context, and FP4 • A starter set of 5 popular models • GPU and Apple Silicon modes VRAMFit Pro (one-time upgrade) • The complete 20-model 2026 catalog • Per-quantization memory breakdown for every model • Advanced tools: KV-cache compression and multi-token prediction estimates PRIVATE BY DESIGN VRAMFit runs entirely on your device. No account, no sign-in, no tracking, and nothing about you leaves your iPhone. The numbers you enter stay with you. Stop guessing whether a model will fit. Check first, download once.
