Model Early Access Builds
Per-model early access container builds shipped ahead of stable releases
See also: Release Artifacts for the stable release inventory and platform previews | Support Matrix for hardware and platform compatibility
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.
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 instead.
GA path legend:
- Promoted — the recipe runs on the stock
:X.Y.Zstable release container; the early access image is superseded.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.

v1.2.0 release
The Tag column shows the GitHub release tag. Unlike the single-image builds above, these previews publish per-arch/CUDA container tags (for example
vllm-runtime:1.2.0-deepseek-v4-cuda13-dev.3) — see each build’s Container Images table below for the pullable tags.
