Vercel, a cloud computing platform for web developers, has recently modified its terms of service. The most relevant change concerns the training of artificial intelligence models. According to the new terms, Vercel will use the code of users on hobby or free plans to train its own models.

Affected users have a 10-day period to exercise their right to opt out of this practice. Failure to opt out within this period implies implicit acceptance of the use of their code for Vercel's model training.

This change raises important questions about data privacy and sovereignty, especially for those developing applications with specific compliance requirements. For those evaluating on-premise deployments, there are trade-offs to consider, as highlighted by the analytical frameworks available on /llm-onpremise.
