About

CTGT builds a model-agnostic platform using mechanistic interpretability to enforce policies, prevent hallucinations, and provide audit trails for AI in high-risk enterprise environments. It converts SOPs and regulations into machine-readable rules that AI follows automatically, enabling Fortune 500 companies in finance, insurance, and media to deploy reliable generative AI. This solves the alignment and reliability bottleneck by intervening at the model's representation layer without fine-tuning or prompts.
