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 Epho
epho runs claude code, codex, or opencode in the cloud. POST a message, stream back the work. no sdk, no daemon, no infra on your side. one request boots a fresh cloud environment with the harness you picked, clones your repos into it, connects your tools, hands it your prompt, and pipes everything back as it happens. sse streams back the whole run, tool calls, edits, the final answer. a chat is a durable conversation with a sandbox attached.
