short_description: Explore a Transformers PR diff and its review threads
---

Interactive prototype of the unified diff panel for the Transformers CI dashboard.

This demo includes a saved public snapshot of
[huggingface/transformers PR #43451 — Add Molmo2](https://github.com/huggingface/transformers/pull/43451),
with 23 changed files and all 730 inline review comments and replies. The snapshot
was downloaded on October 10, 2026; it does not refresh from GitHub.

Use the file and comment filters to explore the changes. Reviews open by default;
select **Inline** for code review threads. **Show the line(s)** highlights the code,
including saved context for comments on an earlier revision.

Click a line number to add an inline comment, use **Reply** in a thread, or select
**Add comment** under the comment filters. These demo comments stay only in the
current page's memory, disappear on refresh, and are never posted to GitHub.

The server uses only Python's standard library and runs on the free CPU tier.
It has no GitHub credentials or access to the production dashboard.

The diff contains source code from Hugging Face Transformers, licensed under
Apache 2.0. Comments retain their authors and public GitHub attribution.
