Release ThinkTwice reasoning models on Hugging Face #1
Description
Hello,
I'm Niels and work as part of 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/2604.01591.
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.
Would you like to host the model checkpoints you've pre-trained using the ThinkTwice framework (the versions of Qwen3-4B and OLMo3-7B) on https://huggingface.co/models?
Hosting on Hugging Face will give you more visibility/enable better discoverability. We can add tags in the model cards so that people find the models easier, link it to the paper page, etc.
If you're down, leaving a guide here. If it's a custom PyTorch model, you can use the PyTorchModelHubMixin
class which adds from_pretrained and push_to_hub to the model which lets you to upload the model and people to download and use models right away.
If you do not want this and directly want to upload model through UI or however you want, people can also use hf_hub_download.
After uploaded, we can also link the models to the paper page (read here) so people can discover your model.
You can also build a demo for your model on Spaces, we can provide you a ZeroGPU grant, which gives you A100 GPUs for free.
Let me know if you're interested/need any guidance :)
Kind regards,
Niels

Hi Niels,
Thank you for reaching out. We're glad that our paper got featured!
We've actually already uploaded the artifact to Hugging Face here:
https://huggingface.co/difanjiao/ThinkTwice-Qwen3-4B-Instruct and https://huggingface.co/difanjiao/ThinkTwice-Olmo3-7B-Instruct
We'd love to have it linked to the paper page if possible. Please let us know if there's anything else we should do on our end.
Thanks again for your support.
Best regards,
Difan

Hey @difanj0713, it's great to see that you've uploaded the artifacts to the Hugging Face hub.
However, it seems they are not yet linked to the paper page. Could you link them by mentioning the paper URL (preferably https://huggingface.co/papers/2604.01591, otherwise the arXiv abstract or PDF URL) in the README of the Hugging Face model repos?
This will make the artifacts automatically show up on the paper page.
See also here for more information: https://huggingface.co/docs/hub/model-release-checklist#write-a-comprehensive-model-card
Additionally, would it be possible to mention/link the Hugging Face models in the README of this Github repo? Thanks

All done! Thanks for your help again.

Thanks so much @difanj0713 for uploading the ThinkTwice models to the Hugging Face hub and linking them to the paper page. The models are now discoverable on https://huggingface.co/papers/2604.01591 and the README looks great with the badges.
If you haven't already, feel free to claim the paper page by clicking on your name on the paper page - this will display it on your Hugging Face profile.
Thanks again for making your artifacts available on the hub.
