# Model Early Access Builds

> **See also:** [Release Artifacts](/dynamo/resources/release-artifacts) for the stable release inventory and platform previews | [Support Matrix](/dynamo/resources/support-matrix) for hardware and platform compatibility

<Warning>
**Model early access builds do not go through QA validation.** They are experimental builds intended for early testing of a specific model. They may contain bugs, require pinned runtime flags, and receive no patch support. Use a stable release container for production workloads unless the build's GA path below says the recipe is promoted.
</Warning>

A **model early access build** packages a single model's recipe on one runtime container, tagged `X.Y.Z-<model>-dev.N` and cut from a side branch ahead of that model's launch — independently of the stable release cadence. When the model's backend patches land upstream in the versions a stable release ships, the recipe is **promoted** to the plain `:X.Y.Z` release container and the early access image is no longer needed.

Full-platform early access builds (`vX.Y.Z-dev.N`, covering all runtimes, wheels, crates, and Helm charts) are **platform previews** and are documented under [Early Access Artifacts](/dynamo/resources/release-artifacts#early-access-artifacts) instead.

**GA path legend:**

- **Promoted** — the recipe runs on the stock `:X.Y.Z` stable release container; the early access image is superseded.
- **Dev-only** — the model still requires this early access image (its patches are not yet in a stable release).
- **Recipe in GA** — the model ships as a recipe on the standard release container.
