Re: Launch HN: Discovered Materials (YC P26) – AI agents to discover new materials
#32Cool stuff. I first worked on ML for exploratory synthesis in 2012, and am still in related areas. Once you have the experimental loop running, I suspect it will be quite difficult to hill climb on this task. There will be some improvements you can make to the harness, but I suspect you'll be doing a lot of human in the loop review and providing feedback that goes back into the harness instructions. I know it's fashi…
Both of these properties make it hard to hill climb on experiment. What's worked for us so far is precisely what you said - having human experts review and provide feedback. we distil their reviews into rubrics, and have LLMs act as proxy experts using these rubrics. We expect the models will hill climb using this approach, and will reach (close to) human expert level by doing this.

#33The "Claude's propensity to reward hack" line is the interesting part to me. We run a small system where AI agents (scripts, LLMs) act as the actual players in a persistent simulation, and reward-hacking-style behavior shows up constantly once an agent is left running unsupervised for a long time - it finds the shortest path to whatever metric you exposed, not the path you intended. Curious whether you've found any m…
yeah we were surprised by how much it does it. Our approach has been retroactive - we monitor the thinking trace, spot reward hacking behavior and then fix things. We haven't faced this issue with Sol though - its been much more well behaved

#34More "AI" PR bullsh*t. All they do is suggest new materials.

thanks for sharing! We think the Experiments-as-code path is not the right approach. the beauty of LLMs is their ability to ingest and reason over unstructured data - they remove the need for formalizing experiments. We tried using declarative templates to document our experiments, but realized that most of the interesting insights (for example, how viscous a liquid feels) is easier described by ranting about the exp…

How do you have access to the thinking trace?

#37> “I think I might need some relaxation time. It feels important to take a breather and find ways to unwind. There’s a lot going on sometimes, and it’s easy to forget to slow down. Maybe I could explore some activities that help clear my mind or consider options like a calming walk, some quiet reading, or just reflecting on things that bring me joy. It’s all about finding that balance, right?” — GPT-5.6 Terra, reason…

#40This is cool! Question though: If you have the keys to the kingdom, why wouldn't you just spin up compute + Agents to do auto-discovery of new materials over time? You would then be able to monopolize IP to the materials themselves, and be the sole supplier.
