The platform allows users to test prompt performance with more than 150 LLMs, enabling them to configure their own models as needed. Users can optimize prompts for various factors, including output quality, robustness, cost, and speed. Promptmetheus ships with 15 providers out of the box, but users have the flexibility to configure their own models as well.
One of the key features of Promptmetheus is its ability to compose structured prompts using text and data blocks, allowing for rapid iteration through different versions. The platform includes automatic evaluators that can be configured to validate completions against specified requirements, ensuring high-quality outputs.
Users can organize their work into projects, tracking relevant statistics on a dashboard. The model catalog allows for testing prompts across various LLMs, and users can define variables at both the project and prompt levels to maintain flexibility and consistency. Completion quality can be rated and visualized, providing insights into performance across different models and variants.
Promptmetheus also offers cost estimation features for completions based on various models and configurations. Changes can be synced in real-time across devices and team members, and users can export prompts and completions in multiple formats, including .txt, .csv, .xlsx, or .json. The platform is designed for both individual users and teams, with features that cater to collaborative environments.
