# Nightly Releases

import { ReferenceStyles } from "../../../components/ReferenceStyles";
import { NightlyBuilds } from "../../../components/NightlyBuilds";

<ReferenceStyles />

Dynamo publishes nightly builds from `main`. Nightlies let you try the latest features and backend upgrades before they land in a stable release. This page covers what nightly publishes, how to install it, and which backend versions the current and recent nightlies ship.

<Warning>
**Nightly builds are experimental and are not QA-validated.** They are built from the tip of `main` and may contain bugs, breaking changes, or incomplete features. Use [stable releases](/dynamo/dev/reference/release-artifacts) for production workloads.
</Warning>

## Recent Nightlies

<NightlyBuilds />

## What Gets Published

Every night, the [Nightly CI pipeline](https://github.com/ai-dynamo/dynamo/blob/main/.github/workflows/nightly-ci.yml) builds `main` and publishes:

- **Container images (CUDA 13):** `vllm-runtime-nightly`, `sglang-runtime-nightly`, and `tensorrtllm-runtime-nightly` to NGC.
- **Python wheels:** `ai-dynamo`, `ai-dynamo-runtime`, and `kvbm` to the NVIDIA prerelease index at [pypi.nvidia.com](https://pypi.nvidia.com/).

Nightly deliberately does **not** publish EFA image variants, `dynamo-frontend`, `kubernetes-operator`, `dynamo-planner`, `snapshot-agent`, Helm charts, or Rust crates. For those, use a [stable or pre-release build](/dynamo/dev/reference/release-artifacts).

## Installing Nightly Containers

Nightly images live in their own `-nightly` NGC repositories so they cannot be pulled accidentally in place of a stable image. Runtime containers use a floating `:latest` tag for the most recent nightly build.

```bash
# Always the latest nightly
docker pull nvcr.io/nvidia/ai-dynamo/vllm-runtime-nightly:latest
docker pull nvcr.io/nvidia/ai-dynamo/sglang-runtime-nightly:latest
docker pull nvcr.io/nvidia/ai-dynamo/tensorrtllm-runtime-nightly:latest
```

The old nightly docs also described immutable `:YYYYMMDD-<shortsha>` container tags. Those tags are not currently visible for the recent NGC nightly images, so use `:latest` unless you have a specific tag from the publish job.

## Installing Nightly Wheels

Nightly wheels are published to the NVIDIA prerelease index at [pypi.nvidia.com](https://pypi.nvidia.com/), not the public PyPI. They are Linux manylinux builds for the Python versions in [Compatibility](/dynamo/dev/reference/compatibility); install on a supported Linux host or inside a Linux container. Nightly versions follow PEP 440 dev versioning, `X.Y.Z.devYYYYMMDD`.

```bash
# Latest nightly (uv)
uv pip install --pre --extra-index-url https://pypi.nvidia.com/ ai-dynamo

# Latest nightly (pip)
pip install --pre --extra-index-url https://pypi.nvidia.com/ ai-dynamo

# Pin a specific nightly wheel
uv pip install --pre --extra-index-url https://pypi.nvidia.com/ "ai-dynamo[vllm]==1.4.0.dev20260803"
```

Backend extras such as `ai-dynamo[vllm]` and `ai-dynamo[sglang]` use the same flags. For TensorRT-LLM, use the nightly container rather than a PyPI extra.

## Backend Versions

Nightlies track `main`, so the backend versions they ship change as `main` advances. To find which nightly or stable build ships a given backend version, and get the exact pull or install command, use the build selector in the [Kubernetes Quickstart](/dynamo/dev/kubernetes/getting-started/quickstart#install-dynamo).

To confirm the exact versions a specific nightly shipped, read them from the pulled image:

```bash
docker run --rm nvcr.io/nvidia/ai-dynamo/vllm-runtime-nightly:latest pip show vllm
```
