Brute force computation is not enough for intelligence. Clever new methods are needed. The science of AI is far from finished. IMHO

Want faster language model inference? MDraft trains diffusion drafters with multi-draft on-policy distillation, boosting accepted draft lengths for more efficient speculative decoding!
[1/8] Can we improve parallel drafters with on-policy distillation? Introducing MDraft: on-policy distillation for diffusion drafters. At T=1, mean acceptance length vs. DFlash: • Qwen3-4B: +11.9% • Qwen3-8B: +13.4% Same inference, just swap the drafter checkpoint! 🧵

I know many PhD students are questioning what their paths mean as AI accelerates scientific discovery. That anxiety deserves to be taken seriously. I wrote some reflections in a recent blog post. My students found them helpful, so I’m sharing them more widely. I hope it offers a little light as we navigate this strange time. Please share it with someone who might need it. pages.cs.wisc.edu/~sharonli/…

I've posted some slides on my website outlining OpenAI's approach to disproving the exponential time hypothesis: msellke.com/Files/ETH-False-… The outline skips some steps, so it gains a smaller power of log(n) in the exponent than the fully optimized algorithm.

Generating proteins -> ??? -> Testing them in the lab The missing piece is SELECTBENCH – evaluating your generations before sending them to the lab - We design metrics to evaluate your model on the selectivity task - We collect three datasets of ON/OFF targets from different sources and of different difficulty levels - We study how modern generative models perform on these tasks (far from perfect) - With SELECTBENCH, the question of generating proteins becomes the question of the throughput of your model! - Check it out at #neurips2026 and benchmark your model using the code from github.com/lovetaro/selectbe… This is one of the links in our long chain of works on generating selective proteins (see my slides for the synthesis docs.google.com/presentation…)
A molecule can bind the right protein and still be the wrong drug. Why? Because it might also bind proteins we don't want it to, potentially causing serious side effects. 📄 Paper: arxiv.org/abs/2610.24124

Parallel Decoding Distillation (PDD) is taking off 🛫 We’ve only released PDD end of July and it’s already adopted in: - Alibaba’s MiniMax H3: huggingface.co/alibaba-pai/M… - WorldPlay2’s causal distillation: worldplay2.github.io/ - FastVideo’s FastH3 Omni: haoailab.com/blogs/fastvideo… - NVIDIA’s large language continuous diffusion model: arxiv.org/pdf/2610.02665 - Amazon’s generative forecasting model: arxiv.org/abs/2610.22358 - NVIDIA’s & MSR’s extensions to parametric student trajectories: alan-lanfeng.github.io/PTD & arxiv.org/pdf/2610.18472 We’ll be open-sourcing our implementation soon - stay tuned!
Having worked with many distillation methods for accelerating diffusion & flow models, I’m still blown away by the simplicity of Parallel Decoding Distillation (PDD). 1️⃣ State-of-the-art quality and diversity with variable NFE 2️⃣ First to scale trajectory-distillation to few-step video generation PDD is about as cheap and simple as it gets: 🎯single, regression-based MSE loss using 1 student & 1 detached teacher forward ❌NO data required ❌NO adversarial loss or alternating training ❌NO JVP or finite-difference approx. ❌NO additional time-embedding or trainable models (e.g. fake score, discriminator) ❌NO stabilization tricks (e.g. normalization, clipping, warm-up)

Exciting to see the community building on FastGen and pushing distillation techniques forward! 🚀 This cool new work builds on ideas from our PDD and PiFlow, exploring novel parameterizations of student heads. Great to see these ideas evolving!
Excited to introduce Simplified Matching Distillation (SMD) for few-step diffusion🧵 No auxiliary score model. No adversarial training. No generator modification. You will get: • Photorealistic appearance • High-quality dynamics • Memory-efficient training • Mode covering with diverse outputs SMD works well across images, video, joint audio–video, and 3D gen, validated across model scales up to 33B parameters. Besides, SMD supports: - Multi-teacher capability merging (like OPD in LLM) - Cross-model capability transfer - Bidirectional teacher to causal distillation Full release. Paper, code, model and data.

1/4 Today, we’re releasing Mercury 3. Mercury 3 is by far our most powerful model and the most intelligent diffusion LLM ever released. It outperforms GPT-6 Luna and Haiku 5.5 on quality while running at 1000+ tok/sec.

A nice presentation by @paveltyletski on Diffusion Gemma: 4x faster text generation. I think that text diffusion will not only be 4x faster and 10x more energy efficient, but eventually it will also be of higher quality, and supersede autoregressive LLMs. youtu.be/3n5RN7i8h2Y?si=YkYz… via @YouTube
