Earlier this week Atlas AI was honored with one of @googlecloud 's most significant recognitions -- 2024 Partner of the Year in the category of Industry Sustainability Solutions. Watch our CEO @AbeTarapani's acceptance speech below. #GoogleCloudPartnerAwards @gcloudpartners
A paper blatantly plagiarized our CTM paper (see some of their verbatim copy&paste below). Feeling bad for my junior collaborators @gimdong58085414 and @JCJesseLai who worked so hard on this.

We sadly found out our CTM paper (ICLR24) was plagiarized by TCD! It's unbelievable😢—they not only stole our idea of trajectory consistency but also comitted "verbatim plagiarism," literally copying our proofs word for word! Please help me spread this.
Very excited about this work: diffusion models finally bridging the gap with autoregressive models on language!

Announcing Score Entropy Discrete Diffusion (SEDD) w/ @chenlin_meng @StefanoErmon. SEDD challenges the autoregressive language paradigm, beating GPT-2 on perplexity and quality! Arxiv: arxiv.org/abs/2310.16834 Code: github.com/louaaron/Score… Blog: aaronlou.com/blog/discrete-… 🧵1/n
We’ve seen Sora, StableDiffusion, GPT-4 transform generative AI for language and computer vision… but can we improve generative models for remote sensing? We present DiffusionSat, a powerful generative foundation model for satellite imagery! arxiv.org/abs/2312.03606 1/8
We analyzed what LLMs know about the world, uncovering more problematic biases
Check out our Stable Diffusion checkpoints fine-tuned with DPO (Direct Preference Optimization, outstanding paper runner up at Neurips). Paper: arxiv.org/abs/2311.12908

🧠Tired of text-only image generation control? Don’t have resources to train for your own tasks? Annoying long sampling time? 📣 Introducing Manifold Preserving Guided Diffusion (MPGD) to solve all these problems! Learn more: kellyyutonghe.github.io/mpgd/ and in 🧵👇 #GenerativeAI
We figured out how to use parallel-in-time solvers (Picard) to accelerate arbitrary computation graphs. You trade parallel compute (use more GPUs) to reduce wallclock time, adding concurrency to otherwise sequential computations. Big speedups on text-to-3D generative models!

Can you give ChatGPT a location and ask it to predict average income, population density, or home value? 😮 …We present GeoLLM, a powerful method for extracting geospatial knowledge from LLMs! Even rivals satellite imagery for prediction tasks 🔥 arxiv.org/abs/2310.06213 1/6
Great work led by my student @linqi_zhou !

📢 Diffusion models (DM) generate samples from noise distribution, but for tasks such as image-to-image translation, one side is no longer noise. We present Denoising Diffusion Bridge Models, a simple and scalable extension to DMs suitable for distribution translation problems.
🔥SOTAs for ONE-step generation, surpassing all GANs, diffusions! Consistency Trajectory Model, co-fisrt author work with Sony's intern, @gimdong58085414 achieves new SOTA FID 1.98 on ImageNet 64 with 1-step! Project page: consistencytrajectorymodel.github.io/CTM/ (w/ @StefanoErmon @mittu1204)
Our work, DOODL, on improved classifier guidance for diffusion models with off-the-shelf classifiers was accepted at #ICCV2023! Enables cool applications like out-of-vocabulary image generation and improved aesthetics. Code: github.com/salesforce/DOO… Paper: arxiv.org/pdf/2303.13703…
Recent GANs are as good as diffusions in quality and run very fast (1 NFE). Our new GAN-based approach StyleSAN-XL scores SOTA in image generation! #GenerativeAI #imagegeneration The code and pretrained are available, so check its quality!

@sirbayes One reason might be because we haven't discovered an elegant generative model for discrete data like text yet. We are just stuck at a local optimum with autoregressive models, similar to how we were stuck with GANs for so long. Discrete diffusions might be the way out.

What was @SlackHQ thinking? This UI upgrade is one of the worst changes I've ever seen in a product I use everyday. Made something that was almost indispensable now unusable. Did you actually test these changes carefully? With people who really use slack? Across many workspaces?
Checkpoints for Diffusion-DPO trained SDXL and SD-1.5 are now available from @meihuadang and @StefanoErmon at the @StanfordAILab! SDXL-DPO obtains 70% win rate over SDXL and is smaller! (1/2) SDXL-DPO: huggingface.co/mhdang/dpo-sdx… SD1.5-DPO: huggingface.co/mhdang/dpo-sd1…
