We recently started using LLUMO. Earlier we were a bit skeptical that it will increase our workload and might delay our project timelines, but it streamlined our end-to-end LLM project. We are now doing double the tests we used to run in a day and have automated benchmarks to measure quality of prompts and output.

What’s so special about LLUMO?

LLUMO is the only tool that gives you smart prompts for your basic prompts and lets you start experimenting in the right direction. Plus, you can test every LLM provider at one place, fine-tune prompt and model configuration. The best part is that you get a 4Cs framework to evaluate your prompt performance right away, you don’t even need target test values to measure these 4Cs, we have built our own proprietary AI models to evaluate these scores and have tested them on 100k+ prompts and output combinations.

Does LLUMO give me real-time analytics?

Yes. LLUMO gives real-time analytics for development and production environments. We gave 4 types of analytics – Quality, Economic, Growth and Technical. We also gave you the most advanced prompt evaluation framework - 4Cs (Confidence, Context, Clarity and Cost).
