Nightly Release Info

Dynamo publishes nightly builds from main every day. 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 past nightlies ship.

What Gets Published

Every night (around 08:00 UTC) the Nightly CI pipeline builds main at a single commit 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.

Nightly deliberately does not publish the 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.

Installing Nightly Containers

Nightly images live in their own -nightly NGC repositories so they cannot be pulled accidentally in place of a stable image. Each nightly is published with:

• a floating :latest tag — always the most recent nightly;
• an immutable :YYYYMMDD-<shortsha> tag — a specific night’s build;
• a -cuda13 alias — pins CUDA 13 explicitly.

$
# 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
$
$
# Pin a specific nightly
$
docker pull nvcr.io/nvidia/ai-dynamo/vllm-runtime-nightly:20260710-abc1234

Installing Nightly Wheels

Nightly wheels are published to the NVIDIA prerelease index at pypi.nvidia.com, not the public PyPI. They are Linux (manylinux) builds for the Python versions in the Support Matrix; install on a supported Linux host or inside a Linux container. Nightly versions follow PEP 440 dev versioning, X.Y.Z.devYYYYMMDD.

$
# Latest nightly (uv — recommended)
$
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
$
pip install --pre --extra-index-url https://pypi.nvidia.com/ ai-dynamo==1.3.0.dev20260710

Backend extras such as ai-dynamo[vllm] 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/install command, see the Quickstart.

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

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