Free AI model cost calculator

Pick any of 354 open models and a workload to see the genuinely cheapest way to run it — free on your own machine, on a rented GPU at the vendor's real price, or via your own API key. Honest, $0-markup math — no account or key needed.

For example, Llama 3.1 8B Instruct (8B, Meta) on a long chat costs $0 on your own machine if you have about 8 GB of VRAM at Q4_K_M, about $0.26/hr on a rented NVIDIA RTX 3090 24GB, or about $0.03/1M tokens via your own API key.
