ZGCM-1 opens a 7.39B search model

ZGCM-1 is a 7.39B-parameter dense model for mathematics and tool-assisted search, publishing weights, training code, data resources, and a 256K-token context under an MIT model license. Its model card reports 97.13% on MATH-500 and 63.09% on WebWalkerQA, while the technical report makes clear these are author-run evaluations. Builders comparing local models should file it beside the archive’s open-weight adoption evidence, as a candidate for a reproducible search trial—not independent proof of frontier performance.
