Free tools

Working calculators and utilities for teams that run their own models. Free, unlimited, no account; they run in your browser.

Pick a model, quantization, and context length; see exactly what memory it needs and which GPUs fit.

Dataset size, epochs, and method to GPU-hours and dollars, at current market rates.

Per-line format checks, token counts, and cost estimates. Your data never leaves the browser.

More on the way: LLM price comparison, self-hosted vs API break-even, and agent cost-per-task. Built from the same live data that runs the platform.
