Basin scores 80.8% on CyberGym

Submersion AI launched Basin at 80.8% on CyberGym, placing it eighth at launch and just above Grok 4.7’s 80.3%, while claiming up to 90% greater cost effectiveness than similarly performing models in its launch announcement. Unlike hosted-only tools, Basin is designed for on-premises, private-cloud, or air-gapped deployment; our earlier cyber-AI airlock analysis gives the governance context. Security teams should treat 80.8% as a vendor benchmark until independent reproduction, but file the private deployment option for environments where hosted cyber models are disallowed.
