Cohere announced a major step toward securing the AI supply chain by introducing model signing on all Cohere Command models hosted on Hugging Face.
As organizations increasingly rely on third-party AI models, the risk of tampering, data leakage, and hidden backdoors has grown.
Model signing, via cryptographic signature, assures integrity, provenance, and claimed properties, so organizations know exactly what the origin and state of the AI artifact they deploy is.
By doing so, companies can write and enforce automated security policies with model signing, thereby easing compliance with security regulations and allowing them to confidently deploy trusted models.
This initiative complements Cohere’s work with CoSAI, a coalition that shapes industry-wide standards for the distribution of trustworthy models.
Today, developers can independently verify signatures using open-source tools, while a step-by-step verification guide accompanies signed models on Hugging Face.
As AI models become more deeply embedded in critical infrastructure, Cohere believes that model signing will eventually be as fundamental to security as SSL certificates are to the web.
The company invites developers to try its signed models today and book a demo to find out more about best practices in deploying secure AI.
