Quality Test endpoint

Test the same prompt across multiple LLM providers

In this example, let's ask some questions about Paul Graham

He is best known for his work on the programming language Lisp, his former startup Viaweb (later renamed Yahoo! Store), cofounding the influential startup accelerator and seed capital firm Y Combinator, his essays, and Hacker News. He is the author of several computer programming books, including: On Lisp,[4] ANSI Common Lisp,[5] and Hackers & Painters.[6] Technology journalist Steven Levy has described Graham as a "hacker philosopher".[7] Graham was born in England, where he and his family maintain permanent residence. However he is also a citizen of the United States, where he was educated, lived, and worked until 2016."""
prompts = ["Who is Paul Graham?", "What is Paul Graham known for?" , "Is paul graham a writer?" , "Where does Paul Graham live?", "What has Paul Graham done?"]

Load Test endpoint

Run 100+ simultaneous queries across multiple providers to see when they fail + impact on latency

Duration Test endpoint

Run load testing for 2 mins. Hitting endpoints with 100+ queries every 15 seconds.
