Reading this guide is free. Mistral Large 4 is a 1 trillion parameter model you can try free in the browser with a Mistral account, download free as open weights, or use through the paid API.
The browser path needs a free Mistral account. Mistral's pricing page lists a Free plan with limited messages, limited web searches, and limited coding sessions. We saw Sign up while signed out; we didn't create an account.
The download path is free but heavy. The full checkpoint is about 1 TB across 54 files. The smallest published copies, community GGUF quantizations from Unsloth, are about 233 GB, and the model needs at least that much memory to run. Mistral's own serving recipe uses 8 server GPUs. We didn't run it locally; we checked the published sizes.
The API path is pay per use: $0.70 per million input tokens, $0.07 per million cached input tokens, and $2.10 per million output tokens, as of October 29, 2026.
Level: intermediate. Nothing to install for the browser path. The self-host path is a server project.
