Use when choosing an open-weight LLM and clearing it for use — which family and size fit the task, the hardware and the budget, and above all whether the license permits shipping. Owns the license-class map (OSI-open versus custom-community versus non-commercial), the always-verify-the-model-card rule, size-to-VRAM budgeting and the quant formats. This layer decides WHICH model and whether the license allows it, then hands off. NOT downloading or hosting on the Hub (that is `huggingface`), NOT…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Open weights — pick the model, then clear the license

This is the CHOICE layer. Given a task, a box, and a shipping constraint, it tells you *which*
open model to reach for and *whether the license lets you ship it*. It does not download, run,
serve, or fine-tune anything — it feeds the skills that do (see [Related skills](#related-skills)).

## The one rule (read before you name a model)

**Model names and their licenses change monthly. Never state a license from memory — open the
model card and confirm it, every time.** This file was authored against cards live in mid-2026;
by the time you read it, versions have shipped and terms have moved. So:

- Treat every specific version/license line below as **[verify the card]**, not as settled fact.
- State the license **class** (OSI-open vs custom-community vs restricted), then send the reader to
  the actual `LICENSE` / terms page for the exact model + size they intend to ship.
- The *decision framework* and the *class taxonomy* are the durable parts. The version list is the
  perishable part. Weight your trust accordingly.

Real, verified-mid-2026 examples of *why* this rule exists — all confirmed against the source, and

How to install

The exact contents, by fingerprint
mdr add ericrisco/rsc-harness/open-weights@sha256:e628511e0b4a547c

The line at the top of this page pins the label git:20260729.b663587, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
