Open source · Field workflows first

Agentic AI for
construction.

AI that executes real construction workflows — from highway bids to hyperscale sites. Built by contractors, for contractors.

Small model in training

Test mud1 — the model we are building

This is the real small LoRA model (weights on your machine via Ollama / desktop), not the hosted website assistant. Ask construction questions. Weak answers go into the next training set.

Local mud1 = Openmud LoRA weights on your machine. Hosted mud1 = RAG + cloud model for everyday use on the site. Both learn from your questions.
