Mstack just had a paper accepted at ICML. In AI, there are many ways to measure progress. One of the clearest signals is when your work earns recognition from the world’s top researchers. International Conference on Machine Learning is one of the most influential machine learning conferences globally, with an extremely competitive acceptance process. Getting in is not just about building fast — it reflects real technical depth and meaningful innovation. It’s been incredible to watch Mstack AI and Shreyans Chopra go from strength to strength: global demand → an R&D-first culture → a native AI approach to accelerating research → and now this milestone at ICML. To us, this is a strong signal that the flywheel is accelerating. What excites us most is that they’re not only building impactful products today, but also contributing to the frontier of what AI can become tomorrow. Huge congratulations to the entire team - proud to be part of the journey.
Thrilled to share that our paper "RETROSPECT: Proposal and Reranking for Single-Step Retrosynthesis" has been accepted at ICML 2026, AI for Science. Most single-step retrosynthesis systems collapse two distinct jobs — proposing disconnections and ranking them — into one stage. RETROSPECT pulls them apart and studies them as separate, reusable units. On the proposal side, we built the ChemAlign Transformer, an encoder-decoder SMILES model trained with hybrid root-aligned/random SMILES augmentation, Pre-LayerNorm, tied embeddings, EMA weights, and a Chemistry-Informed Neural Network loss (CINN). On the selection side, a LambdaMART reranker reorders the merged candidate pool using structural, reaction-template, upstream-score, and Quantum Descriptors. The practical takeaway is modularity. Because proposal and selection are decoupled, the ChemAlign Transformer can stand on its own or slot into larger ensemble-and-ranking pipelines, instead of being locked inside a single monolithic model. By proposing more accurate and more diverse disconnections, RETROSPECT can strengthen the multi-step route search that synthesis planning depends on — giving chemists better starting points when they work out how to actually make a molecule. We're actively hiring AI Researchers working at the intersection of AI/ML and Computational Chemistry — especially those excited about building chemistry-native AI systems, scientific reasoning models, and next-generation discovery platforms. Nice work done by Shreyas V, Ronit kumar choudhary, Arjun Verma and a thank you to the [ICML] Int'l Conference on Machine Learning AI for Science organizing team and reviewers.
