All scored in AI Models & Inference.

What Exa does that Cerebras does not

Exa passes clear canonical domain, llms-full.txt / full agent docs, structured api reference, openapi / spec quality, authentication documented, pricing understandable, request examples provided, response examples provided, errors and status codes documented, self-service signup, programmatic credential creation, free trial or free allowance, fast time to first request, copyable quickstart, cli available, structured, predictable output, machine-readable errors, rate-limit behavior predictable, agent compatibility verified, and Cerebras fails them. That is the whole of the gap between the two scores, so if none of those matter to your agent the ranking above overstates the difference.

Why people look for an alternative

Cerebras fails clear canonical domain, llms-full.txt / full agent docs, structured api reference, openapi / spec quality, authentication documented, pricing understandable, request examples provided, response examples provided, errors and status codes documented, self-service signup, no mandatory sales call, agent-compatible signup flow, programmatic credential creation, free trial or free allowance, fast time to first request, copyable quickstart, cli available, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified. Each one is a place an unattended run stops, which is usually what sends someone looking in the first place.

Where Cerebras loses the points

Cerebras is weakest on understand at 23/100. Without a spec an agent has to guess at endpoints, and it guesses wrong. If that is the part your agent depends on, take the ranking above seriously; if it is not, Cerebras may still be the right pick.

What an agent runs into with Cerebras

These are the findings from the last audit on 2026-09-01. Each one is a place unattended software stops, which is the practical reason to look at the list above.

• Make signup self-serve; an agent cannot sit through a sales call.
• Publish an OpenAPI spec so agents can generate a client.
• Flesh out the OpenAPI: paths, schemas, and descriptions.
• Document error responses as an enum in your OpenAPI.
• Let agents create API keys programmatically.
• Return X-RateLimit / Retry-After headers so agents pace themselves.
• Publish an AGENTS.md or llms-full.txt with full agent context.
• Add request examples to your API reference.
