Local AI Tools & Calculators
16 free interactive tools for running AI on your own hardware — work out how much VRAM a model needs, which GPU to buy, what you can run today, and how local stacks up against the cloud. Every tool is free, needs no signup, and gives instant results.
Calculators
Work out exactly what your hardware can handle — and what it costs.
VRAM Calculator
Enter model size + quantization → the exact GPU memory required to run it.
Quantization Calculator
Compare Q2–Q8, FP8, AWQ and BF16 VRAM for any model size.
AI Cost Calculator
Local hardware vs API (Claude, GPT-5.5, Gemini) — total cost and break-even point.
Apple Silicon AI Calculator
Pick your Mac (M1–M4 × Pro/Max/Ultra) → which models fit and expected tokens/sec.
Fine-Tuning VRAM Calculator
Enter your GPU → which models you can LoRA fine-tune, at which rank and context length.
MoE VRAM Calculator
Enter VRAM + RAM → which mixture-of-experts models (30B–120B) actually run with experts offloaded.
Image Model VRAM Calculator
Pick your GPU → which image models (FLUX.2, Qwen-Image, Z-Image) fit, and at which quant.
Find your model & hardware
Tell us what you have (or want to do) and get a specific, real recommendation.
What AI Model Can I Run?
Enter your GPU/RAM + use case → the best model you can actually run.
Can I Run Local AI? (Yes/No)
Tell us your OS, RAM, GPU and VRAM → instant yes/no + the runtime to use.
Which GPU to Buy
Pick a target model (7B–70B) + budget → the cheapest GPU that runs it.
AI Model Recommender
Select your task and hardware → the best local LLM, instantly.
Model Size Picker
Use case + GPU → a 7B / 14B / 32B / 70B recommendation with the model to use.
Coding Model Router
Pick your coding task + GPU → the best local coding model (Qwen3-Coder, Devstral…).
Leaderboards & comparisons
Live rankings and head-to-heads for models and coding tools.
Fix it
Pick the error you are seeing and get the fix for your setup.
