AI engine that turns advanced-materials discovery into a search
Chemistry, structure, architecture and process are held in one object, giving the engine a unified substrate that molecular-only models lack.
Candidate materials are generated from the experiments that surround them in vector space, so predictions stay anchored to real-world results.
The engine treats negative results as high-value information, using them to rule out large regions of the design space faster than positive results alone.
For teams without materials expertise, Mimir's scientists take requirements and deliver a working prototype rather than just a report or a model.
