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 WhisperBar

A Mac menu bar app for writing and skimming. Dictate into any app and get business-casual text, or hear a short summary of anything you copy. WhisperBar cleans grammar, punctuation, and structure, then copies the finished text so you can paste it into Slack, email, or your AI chat. Raw dictation okay codex can you look at the checkout page and figure out why the coupon field is pushing the total down on mobile and maybe just fix the spacing but don't change the desktop layout .
