Aikido Security released Altar-1, an open-weight security model derived from Z.AI’s GLM-5.3 to run on customer-controlled infrastructure. It compresses GLM-5.3 from 1,506.7 GB in BF16 down to 328 GB and can run on a single vLLM node with 4x NVIDIA H200 GPUs. Deployment in closed or air-gapped networks becomes feasible by using public weights, with some fidelity and CVE-recall tradeoffs after expert pruning.
