LSI offers paired cybersecurity models to limited design partners

Lean SuperIntelligence announced offense and defense AI models for on-premise security work, available only to a limited set of design partners. It also says it closed a pre-seed round but disclosed neither its size nor a full investor list. Claims that its models beat frontier systems are vendor claims; a public model artifact or independent benchmark was not verified. Broad customer availability is not established.
