Baseten vs Vespa

Baseten scores higher on the AgentReady, 59/100 against 56/100. They differ on 3 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Baseten. Baseten is an AI inference platform that provides the fastest model runtimes, cross-cloud high availability, and seamless developer workflows.

Vespa. Vespa.ai develops the Vespa AI Search Platform, a distributed serving engine that unifies retrieval, ranking, machine learning inference, and real-time serving for business-critical AI applications.

Where Baseten is ahead

Baseten passes no mandatory sales call and agent-compatible signup flow, and Vespa does not. That is adopt, whether an agent can get a key and make its first successful call without a human in the loop.

Where Vespa is ahead

Vespa passes limits / constraints documented, and Baseten does not. That is understand, whether an agent can read the docs and work out how the API behaves before calling it.

What neither does

Both fail mcp discoverable, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, programmatic credential creation, mcp integration available, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified. If your agent needs any of those, you will be building it yourself either way.

Score, pillar by pillar

The AgentReady splits into four pillars, scored separately, because a product can be easy to find and still impossible to adopt.

Discover. Both sit at 87/100 here. Baseten misses mcp discoverable; Vespa misses mcp discoverable.
