Today is Antoine Guedon's PhD! Already pretty cool visuals right at the start.

Annnnnd it's a reject!

Scale is a religion and if you go against it, you're a heretic and you should burn, "despite [the reviewers] final ratings".

But scale is still not necessary!

Side note: First time swinging reviews up (from 2,2,4,4 to 2,4,4,5) does not get the paper accepted. Strange days.

Dear bsky friends, I have a question: Do you really think that the visual quality of these images is so bad that the research that produced them is deeply flawed?
And if I told you that the model was mostly trained on ImageNet with a bit of artistic fine-tuning at 1024 resolution, still really bad?

Does a smaller latent space lead to worse generation in latent diffusion models? Not necessarily! We show that LDMs are extremely robust to a wide range of compression rates (10-1000x) in the context of physics emulation.

We got lost in latent space. Join us 👇

Next week, I'll be in Strasbourg for the GRETSI (@gretsi-info.bsky.social) to present a small discovery on transformers generalization we made with Simon and Jérémie while working on generative recommender systems. I love these "phase transition" plots.

Congrats to the Dino team for the DinoV3 release!

Seeing it outperforms CLIP on "cultural knowledge" based task like geoloc make me very hopeful for it working really well in VLMs!

Nicolas Dufour @nicolasdufour.bsky.social · Aug 18

🌍 Geoloc is a fantastic downstream benchmark:

- Requires fine-grained visual understanding (textures, vegetation, road signs, architecture)

- Tests global generalization

- Forces models to pick up real-world cues

That’s why DinoV3 shining here is such a big deal 🚀

Nicolas Dufour @nicolasdufour.bsky.social · Aug 18

Even crazier 🤯 DinoV3 works in some out-of-distribution setups too — as long as there are geographical cues 🌄🗺️

(Remember: the network is trained only on road images!)

Where DinoV2 totally failed, DinoV3 is holding up 👊

The setup 👉 We use our riemannian flow matching model PLONK (CVPR25: Around the World in 80 Timesteps: A Generative Approach to Global Visual Geolocation) 🌍

We simply swap StreetCLIP with DinoV3 as a drop-in backbone, and train on OpenStreetView-5M.

And boom 💥 — DinoV3 wins.

🚀 DinoV3 just became the new go-to backbone for geoloc!
It outperforms CLIP-like models (SigLip2, finetuned StreetCLIP)… and that’s shocking 🤯
Why? CLIP models have an innate advantage — they literally learn place names + images. DinoV3 doesn’t.

I had the privilege to be invited to speak about our work "Around the World in 80 Timesteps" at the French Podcast Underscore! If you speak french, i highly recommend it they did a great job with the montage!

1/ Can open-data models beat DINOv2? Today we release Franca, a fully open-sourced vision foundation model. Franca with ViT-G backbone matches (and often beats) proprietary models like SigLIPv2, CLIP, DINOv2 on various benchmarks setting a new standard for open-source research.

Really cool work! I've seen that you haven't used registers but seem to have smooth latents anyway. Is this a consequence of having the matryoshka loss that require both global and local knowledge?
Have u tried using registers?

✨Thrilled to see EurIPS launch — the first officially endorsed European NeurIPS presentation venue!

👀 But NeurIPS now requires at least one author to attend in San Diego or Mexico (and not just virtually as before). This is detrimental to many. Why not allow presenting at EurIPS or online?

A bit disappointed by the PAMI TC meeting, mostly repetitions of what’s been said at the opening, the "open discussion" slide was really just there to *exist* but no discussion/vote took place, no topic was debated. What space is left to reflect on our community and what we stand for as scientists?
