Risks

Low, just an additional API option (that's really fast)

Background

Venice.ai is an artificial intelligence platform that provides access to advanced AI models, prioritizing user privacy by storing data only in the user's browser. It offers a paid version, Venice Pro, with higher limits and customization options, which is also available for free to users holding 1 Morpheus (MOR) token. The platform supports document uploads and image generation, and has a presence on Twitter, Farcaster, and Instagram.
