LM Studio 0.3.28 is now available as a stable release. Update in‑app or download the latest version.

New: Model variant picker in My Models

When you download a staff picked model, you can often choose between multiple variants of the model. For example, you might be able to choose an MLX and a GGUF variant of the same model, or between different quantizations (e.g. 4-bit, 6-bit, or 8-bit).

Starting in 0.3.28, you can now quickly select which variant will be used by default when you load the model, either in the app, API calls, or with the CLI.

Quickly select which model variant will be used by default

This will work for any model.yaml with multiple sources, including models you create yourself. See more in the docs.

Improved RAM/VRAM usage estimation

  • Significantly improved RAM/VRAM usage estimation in the following cases:
    • Mixed quantizations
    • Models with inaccurate parameter labels in metadata
    • Non‑transformer models

Misc UI polish

Fixed lots of UI flickers on My Models page, and fixed model parameter counts not displaying for some models.
