New version of ChemCrow out 🔥🔥 arxiv.org/abs/2304.05376 The LLM-powered chemistry assistant got major updates 💪 What's new? Robots synthesizing stuff, human/crow collaboration, novel molecules, safety, new evaluations + open source release! 🤩 See more 👇 1/8 #compchem

@rheejust @porterdotrun @FirstMarkCap @ycombinator @daltonc @ROWGHANI Huge congrats! Couldn't expect less from such a great team with a great product 🔥

I’m excited to announce that @porterdotrun has raised a $20M Series A to provide effortless app infrastructure in any cloud provider. Our round was led by @FirstMarkCap with participation from @ycombinator and strategic angels including @daltonc and @ROWGHANI. When we started Porter, we had one simple goal: allow startups to stop thinking about cloud infrastructure. Today, the fastest-growing AI companies from the seed-stage to IPO use Porter to manage hyper-growth infrastructure across AWS, Google Cloud, and Microsoft Azure. Our users scale individual clusters in each cloud provider to hundreds of machines and terabytes of RAM without DevOps overhead. We’ve more than doubled headcount over the past few months and are aggressively expanding the surface of what our platform can manage. We are on a mission to make using the public cloud utterly seamless. I’d like to thank our users, investors, and most importantly, the Porter team. As all of them know, we are only getting started. We’re actively hiring with offices in NY and SF, so if you’re interested in managing core infrastructure for the next generation of public companies or tackling the hardest devX problems, shoot me a DM.

You don’t like molecular dynamics? We get it. That’s why at this year’s LLM hackathon for Chemistry and Materials Science, we built not one, but ✨two✨ AI agents for molecular dynamics 👇

@porterdotrun @ZJoncev Thank you guys! it's been a really smooth experience, totally recommend

B-12 (YC S25) brings chemical super-intelligence into your lab, leveraging AI agents to plan and execute complex, multistep syntheses, turning months of R&D into minutes. Co-founders Andres Bran (@drecmb) and Zlatko Jončev (@ZJoncev) use Porter for production-ready infra without any DevOps overhead. Spend less time managing CI pipelines and more time innovating: porter.run/for-seed-stage…

Synthetic Society tests your product with AI-powered user simulations. Their agents mimic real users to catch bugs, bad UX, and edge cases. Ship faster, kill manual testing, and build with confidence. ycombinator.com/launches/O7g-s… Congrats on the launch, @aaronchewbani and @kavandoc!

b-12 (b12-labs.com) is building AI agents that help chemists design experiments and automatically run them on lab robots. They turn months of manual chemistry work into minutes of automated execution. Congrats on the launch @drecmb & @ZJoncev! ycombinator.com/launches/O3V-b…

This week we're in #ICLR2025 in Singapore 🇸🇬!! Do reach out to discuss the future of #AI and #Chemistry 🥂 llms, agents, new tools for chemists and new ways of doing chemistry 🚀

@chemFunMan Thank you!! We have had a great time at the Hawker centers 😅

@drecmb Enjoy Singapore! Try Laksa and Chicken Rice :)

Hello from Singapore 🇸🇬! Thrilled to be at #ICLR2025 presenting our work on fragment-based drug discovery 🧩. We go beyond virtual screening with a generative, structure-aware approach. 📃 openreview.net/forum?id=bZW1H… 🔗 github.com/rneeser/Latent… A thread 🧵👇

Thrilled to present our new work on Reinforcement Learning for 3D Crystal Diffusion Generation in #AI4Mat at #ICLR2025 ! We show that RL can optimize diffusion models for goal-directed crystal generation.

🔥 AutoAdsorbate 🔥 has been the workhorse of high throughput computation in heterogeneous catalysis modeling and ML @BASF for the previous few years. 🧵 Now it is available open source! #MatSci #CompChem Preprint: doi.org/10.26434/chemr… Code: github.com/basf/autoadsor…

AdsMT is finally out in @NatureComms 🥳 It is designed for rapid prediction of global minimum adsorption energy (GMAE) from surface graphs and adsorbate descriptors. Thanks to @XuHuang461675 , @pschwllr and @NCCR_Catalysis! Paper & code: nature.com/articles/s4146… @SchwallerGroup

Exciting new preprint! 🧪🤖 Our work shows how LLMs can steer search processes in chemistry! Great collaboration with: @drecmb @TheoNeukomm @d_armstr and @pschwllr in amazing @SchwallerGroup at @EPFL_en Check the demo for steerable retrosynthesis 🍿👇

We just released a preprint with my wonderful coworkers @drecmb @d_armstr @ZJoncev @pschwllr showcasing how LLMs can refine a search in the chemical space using natural language as their compass. Preprint can be found at arxiv.org/abs/2503.08537, more on that below: 1/🧵
