Hello, world. We’re Principled Machines. Language models are one form of intelligence. We’re building Cortex to combine them with algorithms, solvers, and reusable methods. Our bet: better models make the system around them more powerful. principledmachines.com/resea…
Reasoning as a systems problem — Principled Machines

Reasoning as a systems problem — Principled Machines

Frontier models are the kernel of a capable system, but far from a complete reasoning engine. A model can propose a plan, but reliable reasoning also needs executable representations, enforced...

Sharing an early result: Sierra verified Cortex at 73.2% on τ³-benchmark. We build algorithmic complements to LLMs. We don’t fight what models do well. We fill in the rest. principledmachines.com/resea…
Cortex on τ³-bench — Principled Machines

Cortex on τ³-bench — Principled Machines

On τ³-bench banking, Cortex passed 73.2% of tasks, against 55.2% for the best published model. Sierra's own paper shows that finding the documents is half the problem. We describe how Cortex handles...
