Tools
Five calculators and generators, plus the two indexes behind them. Every figure they produce is computed from the model index on this site, not typed in by hand.
- VRAM Calc
Estimate VRAM for any quantized LLM — or any model on Hugging Face — with a verdict for your card or mixed cards, the speed ceiling, the wait before the first token, how many people it can serve, and the memory to fine-tune it.
- CLI Gen
Generate runnable llama.cpp, Ollama, vLLM and ExLlamaV2 commands for any indexed model, including Docker and Compose variants.
- Format Wizard
Answer three questions about your hardware and priorities to get a quantization format, runtime and quant level that actually run together.
- Compare
Put two quantized models side by side: parameters, context, VRAM at your chosen context length, speed and quality loss.
- Feel the speed
Stream one sentence at a card's measured or scaled token rate, side by side with another card. Bandwidth ceilings are labelled and are not played back as a speed.
Quick answers by card
The calculator's three follow-up answers — speed, which quant level, longest context — worked out in advance for the most common cards, plus a lookup for the errors people hit when a model will not load.
- How fast
Tokens per second for the models that fit the most common cards: a calibrated estimate from each card's own measured run, and the upper bound its memory bandwidth sets.
- Which quant
Which quant level to download for each recommended model on the most common cards: every level sized at 4K context, and the highest-quality one that fits comfortably.
- How much context
The longest context each recommended model keeps comfortably on the most common cards, with the default fp16 KV cache and with the cache quantized to q8_0 or q4_0.
- Error lookup
The messages llama.cpp, Ollama, vLLM, ROCm and Docker print when a model will not load or will not use the GPU — each quoted from the project's own source, with what it means and what fixes it.
Browse by hardware or format
- GPU pages
One page per card — 78 of them — listing which of the 125 indexed models fit it comfortably at 4K context, at what quant level, with how much headroom.
- Format comparisons
4 head-to-head pages — GGUF vs AWQ, GGUF vs EXL2 and the rest — on hardware support, runtime and the models this index ships in both formats.
