Start from the best open models
Training frontier models from scratch is expensive. Kuartal starts from the strongest open-weight models available and re-checks them every quarter.
How a Cortex is trained.
Train on an industry's work
Each model is constrained to one industry's scope, so its capacity goes into understanding that work and doing something about it.
Split the job across specialists
Separate models handle language, retrieval, speech, documents and safety, with a router choosing which one answers.
Keep retraining
As a client keeps feeding its Cortex data, Kuartal keeps teaching it, so it matures and handles new complexity.
