Where Groq is ahead

Groq passes llms-full.txt / full agent docs, and Cerebras does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: structured api reference and authentication documented. Cerebras misses those.

And on adopt, self-service signup, agent-compatible signup flow, fast time to first request and copyable quickstart. Cerebras misses those.

Finally, on operate, structured, predictable output. Cerebras misses it.

What neither does

Both fail clear canonical domain, openapi / spec quality, pricing understandable, request examples provided, response examples provided, errors and status codes documented, no mandatory sales call, programmatic credential creation, free trial or free allowance, cli available, 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.
