Aikido squeezes 753B model onto one node

🔥 What happened Aikido Security released Altar-1, an open-weight security model built on Z.AI's GLM-5.3. Through 4-bit quantization and REAP expert pruning, it shrinks from 1,506 GB to 328 GB – a 78 percent reduction. 💡 Why it matters The model runs on a single node with 4x H200 GPUs and fits air-gapped networks. On Aikido's internal CVE benchmark, it retains 92 percent of the parent's hit rate – with only a 5.2-point recall drop. ⚡ Our take Finally, a security model that doesn't ship customer data halfway around the world. Anyone still using closed-source APIs for pentesting has been asleep at the compliance wheel.
