Release UI-TARS-1.5 and UI-TARS-2 models on Hugging Face
Hi @lovesnowbest 🤗
Niels here from the open-source team at Hugging Face. I discovered your work through Hugging Face's daily papers as yours got featured: https://huggingface.co/papers/2509.02544. The paper page lets people discuss about your paper and lets them find artifacts about it (your models for instance), you can also claim the paper as yours which will show up on your public profile at HF, add Github and project page URLs.
I noticed in your GitHub README for the ui-tars project (https://github.com/bytedance/ui-tars) that you are offering "early research access" to your top-performing UI-TARS-1.5 model. This paper itself introduces UI-TARS-2, which shows even further improvements.
It'd be great to make these newer checkpoints (UI-TARS-1.5 and UI-TARS-2) available on the 🤗 hub to improve their discoverability and visibility, making them easily accessible to the broader research community. We can add tags so that people find them when filtering https://huggingface.co/models.
Uploading models
See here for a guide: https://huggingface.co/docs/hub/models-uploading.
In this case, we could leverage the PyTorchModelHubMixin class which adds from_pretrained and push_to_hub to any custom nn.Module. Alternatively, one can leverage the hf_hub_download one-liner to download a checkpoint from the hub.
We encourage researchers to push each model checkpoint to a separate model repository, so that things like download stats also work. We can then also link the checkpoints to the paper page.
Let me know if you're interested/need any help regarding this!
Cheers,
Niels ML Engineer @ HF 🤗
Hi， thanks for inviting. Surely we will consider that seriously!
+1! Please release these models on HuggingFace!
Many are eagerly awaiting UI-TARS-2 and the continued open-source efforts around this new state of the art process. Thank you for your hard workk!
