The new defensive tool employs a pruned and quantized architecture to provide AI capabilities that approach frontier performance. Its lightweight design enables the system to fit on one 4 H200s node, reducing the hardware requirements for organizations deploying specialized security infrastructure.

Aikido designed the Altar 1 release to allow users to maintain ownership of their security systems rather than relying on closed-source assistants. The model is based on the GLM 5.3 framework and marks the company's first open-weight model aimed at the defensive AI market.
