Mini toolsArko T
By BitInf
Model family: Qwen
Arko T is a 4B parameter transformer initialized from Qwen3.5 4B and trained on 1.3M prompt to CAD program pairs to produce executable Build123d code from natural language. It formalizes a design state made of feature vocabulary, named parameters, constraints, construction history, and attachments, so generated designs stay editable rather than being static geometry. Benchmarked against seven frontier LLMs on 12 metrics across Text2CAD Bench, it scores best on 8 metrics and second best on 3 more, at roughly a tenth of the per benchmark cost, while running at 0.41 seconds per item on local GPUs.

Overview
Arko T is a 4B parameter model that converts natural language design requests into executable, parametric CAD programs. Unlike text to 3D systems that output static meshes, it preserves named features, parameters, and construction history so the result is an editable engineering design, not just a rendered shape.
