What each one is
Vellum. A personal AI assistant that lives in the secure Vellum Cloud, has its own identity, and actually does things in the world.
Venice. Venice is a private AI platform that provides access to leading AI models with privacy-focused features.
Where Vellum is ahead
Vellum passes search discoverable, clear canonical domain, clear product positioning, public docs discoverable, llms.txt published, llms-full.txt / full agent docs, api discoverable, mcp discoverable, package / cli discoverable and machine-readable metadata, and Venice does not. That is discover, whether an agent can find the product at all without being told it exists.
It also holds understand: pricing understandable. Venice misses it.
And on adopt, self-service signup, no mandatory sales call, free trial or free allowance, fast time to first request, copyable quickstart, official typescript sdk, official python sdk, cli available and mcp integration available. Venice misses those.
What neither does
Both fail agent compatibility verified. If your agent needs any of those, you will be building it yourself either way.
