Describe a part, and CytherCAD writes the program that builds it: a compact autoregressive model produces executable parametric construction programs, constrained decoding restricts invalid geometry as it generates, and a geometry kernel checks the result. It runs on-prem, private and air-gapped.

CytherAI’s product: validated by CytherAI’s own test, with no deployment claimed. CytherAI chose the 192 descriptions from the Text2CAD dataset (48 for each of four kinds of operation, across its four levels of detail) and ran the test itself: one part for each description from each of CytherCAD’s two ways of reading it. A part is invalid if it does not build or fails the kernel’s check; a valid part is not necessarily the part described. In May 2026 the check was tightened to count a failed fillet or boolean step as invalid, and the test has not been run again since. Figures published for other systems with the Text2CAD dataset come from its authors’ own test, on other descriptions with another check, and are not compared here.
