Summary of ChangesHello @fzyzcjy, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request refactors the weight version update mechanism within the system. It addresses an architectural concern by relocating the logic for updating the weight version from the HTTP server's endpoint handlers to the underlying tokenizer management and communication layers. This change promotes a cleaner separation of concerns, ensuring that weight version tracking is managed directly by the components responsible for model weight updates, rather than by the API interface.

Code Review
This pull request refactors the weight version update logic, moving it from the HTTP server layer to the manager/communicator layer. This is a good architectural improvement that enhances separation of concerns. My main feedback is regarding the code duplication introduced by this change. The logic for updating the weight version and its corresponding message is repeated in four different methods across two files. I've suggested extracting this into a shared helper method to improve maintainability.
| if success and obj.weight_version is not None: | ||
| self._update_weight_version_if_provided(obj.weight_version) | ||
| message += f" Weight version updated to {obj.weight_version}." |

This logic for updating the weight version and message is duplicated in a few places (update_weights_from_tensor, update_weights_from_ipc in this file, and update_weights_from_disk in python/sglang/srt/managers/tokenizer_manager.py).
To improve maintainability and reduce redundancy, consider extracting this logic into a helper method within the TokenizerCommunicatorMixin class. Since TokenizerManager inherits from this mixin, the helper will be available in all required locations.

| self._update_weight_version_if_provided(obj.weight_version) | ||
| message += f" Weight version updated to {obj.weight_version}." |

This is another instance of the duplicated logic for updating the weight version. Extracting this to a shared helper method would make the code more DRY (Don't Repeat Yourself).

This is another instance of the duplicated logic for updating the weight version. Since TokenizerManager inherits from TokenizerCommunicatorMixin, a helper method defined in the mixin could be used here as well to avoid repetition.

e.g. engine api will not have this feature before the code change, also the location can be improved
