Summary by CodeRabbit

• New Features
  • Improved model loading to allow specifying a checkpoint name during speedup operations. This provides more flexibility when selecting and accelerating models.

Walkthrough

The SpeedupMixin.speedup method was updated to accept an optional ckpt_name parameter, which is now forwarded to the booster function. The OneDiffCheckpointLoaderSimple.onediff_load_checkpoint method was also updated to pass ckpt_name when invoking speedup. No other logic or control flow was changed.

Changes

File(s)	Change Summary
onediff_comfy_nodes/_nodes.py	Updated SpeedupMixin.speedup to accept and pass ckpt_name; updated OneDiffCheckpointLoaderSimple.onediff_load_checkpoint to pass ckpt_name to speedup.

Poem

A patch for the speedy, a hop for the name,
Now ckpt_name travels through the code’s gentle frame.
From loader to booster, the parameter flows,
Like a rabbit with secrets that only it knows.

Tip

⚡️ Faster reviews with caching

• CodeRabbit now supports caching for code and dependencies, helping speed up reviews. This means quicker feedback, reduced wait times, and a smoother review experience overall. Cached data is encrypted and stored securely. This feature will be automatically enabled for all accounts on May 16th. To opt out, configure Review - Disable Cache at either the organization or repository level. If you prefer to disable all data retention across your organization, simply turn off the Data Retention setting under your Organization Settings.

Enjoy the performance boost—your workflow just got faster.

46-81: Good addition for checkpoint-based caching!

The addition of the ckpt_name parameter to the speedup method and passing it to the booster function is a good fix for the quantization cache issue. By using the checkpoint name as an identifier rather than just a temporary UUID, this enables more persistent caching based on the actual model being loaded. This should improve performance when the same checkpoint is loaded multiple times across different sessions.

238-252: Successfully propagating checkpoint name to the speedup function

This change properly forwards the checkpoint name from the loader to the speedup method, completing the fix for the quantization cache. Now the booster can use the checkpoint name for caching purposes rather than relying solely on temporary UUIDs.
