About Black
A black-box evaluation of how AI-generated tests find functional bugs in live APIs. The harder question is whether those tests find bugs. Each system receives only a JSON schema and one valid sample payload, then must generate API test cases that expose failures in a live reference API. The evaluation uses APIEval-20 v1.0, a black-box benchmark contributed by KushoAI. Because KushoAI is also one of the evaluated systems, this report includes the methodology, workflow definitions, repeated-run setup, and robustness checks so readers can understand where the performance difference comes from.
About Cerver
Infrastructure for AI sessions. One API for transcript, model, and compute. Run any agent on any compute, and switch mid-session without losing the thread. Swap the model or the machine under a live session: next month's model is a config change, not a rewrite. Why CFOs love it Every run attributed, per product, per user. Caps on by default: one runaway agent can't write the invoice. Every run leaves a transcript: an audit trail by default.
