Aikido Security released Altar-1 ——their first open-weight security model. According to MarkTechPost, the model is described as a compressed version of GLM-5.3 from Z.AI with a size of 328.

Altar-1 is intended to operate within an infrastructure controlled by the customer. The model is used in Aikido Machine—an autonomous device for penetration testing in local and isolated networks.

The significance of the release lies in an attempt to combine autonomous security testing with the customer's control over the runtime environment. However, the only available material is a publisher metadata résumé rather than a detailed technical description or independent verification.
