Prospector makes scientific graph reasoning local

Prospector’s real breakthrough is systems efficiency: it turns graph navigation into a learnable policy instead of outsourcing every reasoning step to a frontier model.

• –Reaches near-frontier accuracy on the semiconductor benchmark while using a fraction of hosted-model cost
• –Keeps proprietary graphs on local hardware, with reported support for GPU and Mac-based offline serving
• –Frozen weights transfer to bio-inspired materials, PFAS, and materials-property graphs
• –The released code, adapters, graphs, and evaluation harness make the approach unusually reproducible
• –Results remain bounded by LLM-extracted graphs and a citation gate that checks retrieved-edge membership more than full semantic correctness
