Large Language Model Testing Tool
The definitive test of AI reasoning. A browser-based tool for testing and evaluating large language models in real-time.
Jul 27, 2025The quick brown fox pangram lookup test. Create a language that maps real words to words within the target word list. Then ask the LLM to figure out the sentence and then fill in the missing word(s). Make sure to pick a unique seed number to ensure the LLM has not already solved the puzzle.
Generate the output and pass on to a large language model, and then check the result.
While the input and seeding is deterministic, be careful as the word list or process may change if you reload the page and the server refreshes the list.
