The Story

We call your voice agent, you get a pass/fail in your pipeline. The testing infrastructure for AI voice agents.

VoiceGremlin Start testing Test your Voice Agent from CI E2E testing for AI phone agents - real phone calls, real audio, any functional test, via REST API.

Real phone calls for true end-to-end validation Building automated tests against a phone agent represents a major side-quest for your DevOps team, but skipping that test is dangerous - if the support line isn't working, how would your customers tell you? VoiceGremlin calls your voice agent's number from a real carrier line so that your e2e test really covers everything: the SIP integration, STT/TTS, and the agent's functional behavior. LLM as Tester, LLM as Judge With an intelligent support agent, the user's intent is the test case. This means there's no need for a test case repository or brittle scripted conversation paths - just pass in a plain English description of what you want to validate. Our agent calls yours and role-plays as a customer, and once the call is complete, the transcript is then passed to a Judge LLM which evaluates your agent's behavior against your test goal. The final pass/fail is supplied by inference, not keyword matching or regex. Ridiculously easy to implement The VoiceGremlin API was designed around one goal: fast, easy implementation. Your CI or test framework makes two calls: the first one to pass us the phone number and test case, and the second to get the result. There's no SDK and no test case repository to manage. If your tests know how to call an API, the story to build and

AI stories from Hacker News. Browse trending and recent posts, and see the AI percentage on each Hacker News page. JavaScript is needed to load the live feed. You can also browse AI stories on Hacker News Search . Some people are making Hacker News without AI. This is the opposite, only AI news. We discover posts from Hacker News’s rankings and recent submissions, without an AI keyword search. We read accessible articles and use an AI model to judge whether AI is a central topic, not just a passing mention. Results are cached and new posts are reviewed in the background. Trending balances points and recency; new sorts by time; top this week sorts by points. The percentage uses the same classifications for every post in HN’s top-story ranking , 30 posts per page. “Read” means article or submission content was analyzed. When an article is blocked, a confident headline classification may be used and is marked “title only”; otherwise the topic stays unknown. A range shows the minimum and maximum AI share while unknowns remain. Hover over a block to see its classification. These are model estimates, and HN’s displayed pages may differ.

Llm::request tries each endpoint in turn; one that fails is marked down for 60 s and the next is asked.
