Run configurations

Python 3.15

Run configurations now accept python: "3.15":

type: dev-environment
python: "3.15"
ide: vscode

The default Docker image now preinstalls Python 3.11 to 3.15. Runs use the preinstalled build instead of downloading Python on every container startup. See python.

Backends

Lium

The release adds experimental support for Lium. The lium backend supports GPU runs, private Docker images, and volumes.

projects:
  - name: main
    backends:
      - type: lium
        creds:
          type: api_key
          api_key: ...

dstack offer -b lium --group-by gpu

 10  B300:270GB:1..8    on-demand  8..10       lium

Lium volumes use S3-backed storage, grow with usage, and can be mounted in any Lium region, so size and region are omitted:

type: volume
backend: lium
name: my-volume

GCP TPUs

Important

TPU offers are no longer suggested by default. If you use TPUs with the gcp backend, enable them with tpu: true before upgrading.

TPU support is experimental, and TPU offers used to appear for anyone with a GCP backend. It is now opt-in:

projects:
  - name: main
    backends:
      - type: gcp
        project_id: my-project
        creds:
          type: default
        tpu: true

See GCP.

UI

Offers

The Offers page now shows CPU offers as well. Turn off the new GPU toggle to see CPU cards, group offers optionally, and filter by GPU vendor. Each offer shows its hourly price, with price ranges for grouped offers.

The Fleet page has a new Offers tab with the offers matching the fleet, which helps check available capacity, including for CPU-only SSH and Kubernetes fleets. Fleet instances are now shown below the General section.

User projects

The Projects tab on a user page now lists the projects the user owns or has joined, with their role in each.

Qwen3.8-Flash-Next coding agents

A new post shows how a single 4xH200 node, optimized with dstack presets, serves 16 concurrent Qwen3.8-Flash-Next coding agents with roughly 3x lower latency than the available providers.
