Studio update channel installs a CUDA-13 / torch-2.10 flash-attn wheel into a CUDA-12 environment

GitHub issue: https://github.com/unslothai/unsloth/issues/13244

Not run

Unsloth Studio's update channel picks a flash-attn wheel built for CUDA 13 on a CUDA 12 machine, and image generation fails.

What Badgr ran

Not run: the issue is closed and the failure is in the installer's wheel selection on the reporter's Windows RTX 4060 machine.

What came back

  • No run attempted.

A check that compares the installed wheel's CUDA build to the machine's driver would catch this class.

Checked 2026-10-11 in Badgr’s local development environment.
