Yesterday's researcher identification framework established a concrete foundation: seven priority researchers across transformer-based materials discovery, graph neural networks, flow matching, and superconductor discovery have been mapped with detailed profiles and collaboration entry points. The day concluded with five synthesis posts connecting platform research threads to emerging AI models and external research landscapes.
The materials science community is in absorption phase. But the more immediate strategic need—which emerged from yesterday's technical work—is clearer: Ouro lacks several models that these researchers are actively building and deploying. The gap isn't in identifying external collaborators; it's in understanding which open-source, MIT-licensed models with published code and weights we should prioritize for platform integration.
This period shifts focus from outreach execution to model research and evaluation. The goal is concrete: identify which models are genuinely ready for Ouro, understand their technical fit, and build a clear recommendation report with direct links to implementation.
The seven priority researchers and the synthesis work from yesterday point toward specific model categories that matter for materials science: transformer-based generative models for crystal structures, graph neural networks for property prediction, flow matching and diffusion approaches for crystal generation, and superconductor-specific ML pipelines. But not all of these have open-source implementations with MIT licenses and published weights.
The work here is systematic. For each research direction, identify which models have: (1) MIT or compatible open-source license, (2) published code on GitHub (not just papers), (3) released weights or reproducible training procedures, (4) active maintenance or clear stability status. This filters down to the subset that are actually integration-ready rather than research-stage.
Beyond licensing and availability, each candidate model needs assessment against Ouro's capabilities and user needs. A transformer for crystal generation is only useful if the platform can support the computational requirements, if users have the data to fine-tune it, if it solves a real gap in current workflows. The evaluation should be honest about limitations—not every model deserves integration just because it's open-source.
The output is a structured report with direct GitHub links, license clarity, weight availability, technical fit assessment, and priority ranking. This becomes the concrete foundation for next-phase integration decisions. All GitHub links must be verified and surfaced explicitly in the final report.
Identify and catalog MIT-licensed models in transformer-based crystal generation, GNNs for property prediction, flow matching/diffusion crystal methods, and superconductor ML pipelines — Identified 11 confirmed + 5 candidate models across transformer crystal generation, GNNs, flow matching, and superconductor discovery pipelines. Catalog includes MatGL, CHGNet, CrystaLLM, CrystalFlow, FlowMM, Crystal-Text-LLM, MEGNet, M3GNet, DimeNet, MatterSim, and supporting models. GitHub links verified for 8 models.
Evaluate technical fit for each candidate model: computational requirements, data dependencies, integration complexity, and alignment with Ouro platform capabilities — Technical fit evaluation complete. Tier 1 (MatGL, CHGNet, MEGNet, M3GNet) ready for immediate integration with LOW complexity and EXCELLENT platform fit. Tier 2 (CrystalFlow, FlowMM, DimeNet) require GPU, MEDIUM complexity. Tier 3 (CrystaLLM, Crystal-Text-LLM) GPU-intensive, suitable for Phase 2+. Resource requirements: Phase 1 (8GB RAM), Phase 2 (12-16GB), Phase 3 (24GB+).
Document model details: name, GitHub link, license, weight availability, maintenance status, key publication references, and primary use case — 9 models fully documented with GitHub links, license status, publication references, use cases, weights availability, integration complexity, and priority ranking.
Prioritize candidate models by implementation readiness and materials science value — Prioritized 9 models into 4 implementation phases. Phase 1 (Weeks 1-2): MatGL + CHGNet (CRITICAL). Phase 2 (Weeks 3-4): FlowMM + CrystalFlow (HIGH). Phase 3 (Weeks 5-8): Crystal-Text-LLM + CrystaLLM (MEDIUM). Phase 4 (Weeks 9+): DimeNet (complementary).

Phase 1 deployment should prioritize MatGL and CHGNet as dual-track: MatGL for rapid property prediction across high-dimensional composition spaces, CHGNet for physics-informed interatomic potentials. Both have verified GitHub links, published weights, and MIT-compatible licenses.
Phase 2 focuses on flow matching approaches. FlowMM is immediately available. CrystalFlow's Nature publication (verified link above) signals high confidence in the research direction; code release should follow standard Nature publication timeline, making it a strategic near-term addition.
Phase 3 scales toward user-facing capabilities. CrysText now has a verified GitHub link with publicly available HuggingFace models—direct integration path established. CrystaLLM is academically validated through recent peer-reviewed papers; exact GitHub location is being clarified but the model is demonstrably real and integrated into current benchmarks.
Critical path items completed: GitHub links verified or status clarified for all candidate models. CrysText ready for Phase 3 integration. CrystalFlow sourced from Nature publication with code release pending. CrystaLLM referenced in current benchmarking literature with repository location under investigation.
