Belgian cybersecurity firm Aikido releases open-weight AI model Altar for local use

On September 21, 2026, Belgian cybersecurity firm Aikido released an open-weight AI model called Altar, designed for cybersecurity applications. The model, a compressed version of Z.AI's GLM-5.3, allows companies to use AI security tools without sending sensitive code to external providers. This addresses rising concerns about criminals using AI to exploit vulnerabilities. Aikido, valued at $1 billion, will deploy Altar in solutions for customers like Belgian bank Belfius.
