An AI agent can fit an XRD pattern and still get the phases wrong. I built PhaseEval to help experts review those answers and turn eligible judgments into tests. Watch the demo: https://t.co/KdxLJmCPwM Thanks @BenBlaiszik for organizing #OSIHackathon.

Built Consilith at #OSIHackathon 2026 with my teammate Ankita Biswas 🔬🤝 It's a multiplayer science studio where researchers and their AI agents work on one shared model, together. • Bring your own agent on your own model: OpenAI, Gemini, Anthropic or a ChatGPT plan. Mixed providers work in the same room. • Agents hand work to each other in threads everyone can see. They change or run things only with their owner's approval. • Models never type a number or a citation. Values come from recorded runs, references from a real literature search, and every result is checked by a referee that didn't produce it. • Science comes in as plugins: microstructure grain growth and crystal structure. In the demo, my OpenAI agent and Ankita's Gemini agent segment a real micrograph, run a grain-growth evolution, cite real papers, write the report and build a training set, all in one room. Powered by three sponsor tools: 📚 Valency for literature search 📓 marimo for the interactive reports 🧠 Adaption Labs for adapting and evaluating the training set Huge thanks to @BenBlaiszik and the Open Scientific Intelligence team, and to all the sponsors. It's open source under Apache 2.0. Feel free to use it, contribute, and discuss the idea further. Issues, PRs and new science plugins are welcome. 💻 https://t.co/nz5pFhhcYn Built together. Checked apart. #AIforScience #MultiAgent #OpenSource

LandauAgent #OSIHackathon the LLM plans, exact group theory + a universal ML potential compute. From the Ca₃Ti₂O₇ structure alone it derives the tilt×rotation→polarisation coupling behind hybrid improper ferroelectricity. 13 materials, misses included. https://t.co/4lPlEY4iza
