Can reasoning models become overly reliant on chain-of-thought examples? 🤔 Our #ACL2026 work shows excessive CoT supervision is not always beneficial, and gives a recipe for tuning the CoT fraction to improve novel-task accuracy. 🧵 Website: kvignesh1420.github.io/cot-icl-lab

A fascinating reality check for AI coding agents. The new NanoGPT-Bench reveals that current agents (e.g., Claude Code and Codex) only recover 9.3% of human progress on AI R&D tasks.

Can coding agents do research? We release NanoGPT-Bench, an internal eval we’ve used to test agents on an AI R&D problem with months of human progress Codex, Claude Code, Autoresearch recover only 9.3% of human progress, mostly tuning hyperparams & ignoring algorithmic research

Proteo-R1 (ICML 2026), the first reasoning protein foundation model for protein design, is out! 🚀🧬 Most protein design models generate structures without ever *reasoning* about which residues matter. We think that's backwards. Human protein engineers👩‍🔧 don't work this way. They identify critical interaction residues first — charged anchors, hydrophobic hotspots, specificity-determining motifs — and only then optimize geometry around those decisions. ━━━━━━━━━━━━━━━━ 🔬 THE CORE IDEA ━━━━━━━━━━━━━━━━ A dual-expert architecture that explicitly decouples molecular understanding from geometric generation: → ⚡A multimodal LLM (understanding expert) analyzes protein sequences, structures, and text to identify key functional residues governing binding and specificity → ⚡A diffusion model (generation expert) then co-designs sequence + structure — but with those residues locked in as hard constraints ━━━━━━━━━━━━━━━━ 📐 HOW IT'S TRAINED ━━━━━━━━━━━━━━━━ Three-stage curriculum: ① Multimodal Alignment — freeze the LLM, train projections to bridge ESM-2 + AF3-style structural features into language space ② Structural Reasoning Mid-Training — unfreeze the LLM, teach it residue grounding → pairwise geometry → interface localization → hotspot prediction ③ Joint Reasoning-Guided Design — end-to-end on antibody-antigen complexes. Gradients from the diffusion objective flow back through the reasoning expert. ━━━━━━━━━━━━━━━━ 📊 RESULTS ━━━━━━━━━━━━━━━━ Evaluated on simultaneous multi-CDR redesign and the RAbD CDR-H3 benchmark: ✅ Best RMSD & DockQ on RAbD — redesigned H3 loops are geometrically accurate *and* docked well ✅ Lowest backbone dihedral divergence (JSDbb) among all baselines ✅ Reduced intra- and inter-chain steric clashes ✅ Generated sequences score lower perplexity than native antibodies under IgLM & AbLang ✅ Plug-and-play: swapping the diffusion backend to UniMoMo still improves RMSD and IMP ━━━━━━━━━━━━━━━━ 💡 WHY IT MATTERS ━━━━━━━━━━━━━━━━ Proteo-R1 isn't just a better antibody design model. It's a blueprint for coupling deliberative LLM reasoning with any physical generative process — interpretable, modular, and backend-agnostic. 📄 Paper: arxiv.org/abs/2605.02937 💻 Code: github.com/smiles724/Prot… 🌐 Demo: smiles724.github.io/r1/ Great thanks to my wonderful collaborators Weihao Xuan, Heli Qi, @Hanqun_CAO, Heng-Jui Chang, @KKuanPang @XiangruTang Zehong Wang, @hcwww_ , @KejunYing @lupantech Chiho Im, Seungju Han, @richardxp888 @tikgiau.

@KexinHuang5 Super useful feature. Congrats on 🚀 progress!

What if building production-ready predictive models was as simple as asking a question in plain English? Today, we’re launching Kumo Coding Agent Skills, an open-source library that turns coding agents like Claude Code and OpenAI Codex into experts at building advanced predictive models with the Kumo SDK. kumo.ai/company/news/i…

Thrilled that Biomni-AD won the $1M Alzheimer's Insights AI Prize at the AD/PD Conference in Copenhagen 🏆 Most AI tools answer a single question. Biomni-AD is a co-scientist agent. It explores hypotheses, integrates evidence across genetics, proteomics, neuroimaging & clinical data, and explains its reasoning so scientists can interrogate and build on it. Alzheimer's will affect 152M people by 2050. No single researcher can synthesize all that data at once. That's exactly where AI agents change the equation. Proud of the whole team. And it'll be freely available to researchers worldwide 🙏 stanforddaily.com/2026/04/15/bio…

Join me tomorrow to see KumoRFM-2 live! 🚀 The first foundation model to outperform supervised ML on enterprise data, scaling to 500B+ rows. Register here: events.zoom.us/ev/AhSNbvHBKR5…

KumoRFM-2 just became the first foundation model to outperform fully supervised machine learning on enterprise data. Scaling to 500B+ rows. We're doing a free live session to show you how it works. In this session, we'll: - Break down the innovations behind KumoRFM-2 - Demo real workflows end-to-end - Showcase use cases across sales, marketing, and fraud Speakers: - Jure Leskovec - Chief Scientist & Co-founder, Professor at Stanford - Disha Dubey - Data Science Lead - Vid Kocijan - ML Engineer Date: Tuesday, April 21, 2026 Time: 10:00 AM PDT Where: Online, free to attend Register here: events.zoom.us/ev/AhSNbvHBKR5…

@adibvafa Great job! Congrats on an exciting research!

We are excited to announce Biomni Lab has exited research preview and is now generally available! Over the last month, we received and incorporated valuable feedback from our global community of 10K+ scientists. We were amazed to learn that Biomni Lab power users accomplished ~20 months of work in just one. We are introducing a Pro tier (alongside the free tier) with higher usage limits, priority HPC access, and more concurrent tasks so our users can get even more done, faster. Accelerate your science today → biomni.phylo.bio

Exciting innovations on agentic AI for science at Philo's Biomni.

We've been building nonstop since our public launch, and this week we're officially celebrating with the Biomni community! 🚀 On Thursday, join us virtually for a live demo of Biomni Lab by co-founders @KexinHuang5 and @YuanhaoQ, plus recent product updates and how we think about evaluating AI agents in biology. On Friday, we'll feature demos + lightning talks from scientific co-founders @jure and @lecong, plus free swag, drinks, small bites, and plenty of time to mingle. We only have a few spots left, so RSVP soon. • Virtual: luma.com/l5ryjaij • South SF: luma.com/n8k8qb0n We can't wait to see you there!

Scientific analysis doesn’t stop when computation finishes. Results need to be clearly visualized and communicated to be shared and built upon. We’ve revamped visual outputs in Biomni Lab: • Automatic slide deck generation • Reports exportable to HTML, Word, or PDF with embedded figures • Substantial improvements to scientific figure quality Biomni Lab now takes rigorous analyses through to presentation-ready outputs. Try Biomni Lab: biomni.phylo.bio

The @Kumo_ai_team research team - Matthias Fey (creator of @PyTorch Geometric @PyG_Team, Head of Research), Federico Lopez (PhD Heidelberg), and Vid Kocijan (PhD Oxford) - will present their latest research on foundation models for relational data at @UniofOxford 's LoG² seminar. Topic: How Relational Foundation Models enable in-context learning across arbitrary database schemas using graph transformers - without retraining. This is an open event - Oxford ML researchers, PhD students, and anyone interested in the future of graph learning are welcome to attend. Feb 17, 1:00 PM Bill Roscoe Lecture Theatre, CS Department, University of Oxford Thank you @epomqo and @mmbronstein for hosting!

Quite exciting work on synthetic data generation that for the first time demonstrates scaling laws for graph/relational foundation models. Great work by @kvignesh1420 @_rishabhranjan_ @VHudovernik and our collaborators at @Kumo_ai_team and @SAP

LLMs won because they were native to text. Treating tables as flattened tokens was always a hack. Structured data needs its own foundation models — ones that understand schemas, relationships, and numerical semantics from the ground up. That’s where the real enterprise value is. The next big AI wave won’t be prose — it’ll be rows, columns, and relations. forbes.com/sites/rociowu/…
