Evaluation is part of Sutro, but it’s not the whole product. Sutro turns expert feedback into optimized, reusable AI Functions that can run on any model and at any scale.
Sutro helps you teach models your team’s standards, compare their quality and cost, and turn them into reusable AI Functions. Decision models like Jev and Clef can power those Functions when the task calls for structured choices rather than free-form text.
Yes. Sutro supports images, PDFs, and web search capabilities today. Additional modalities and custom tool calling are available on a per-request basis.
Sutro is model-agnostic, and we support a mix of open-source and proprietary models. Small, open-source models commonly outperform larger proprietary models on expert-aligned data processing tasks. Sutro helps automatically find the best model for your needs.
Yes. Sutro can be managed as SaaS or entirely self-hosted. You can bring your own provider keys and cloud credentials in either case.
Sutro is designed to be more robust, accurate, and scalable than prompt engineering, and more data efficient, portable, and re-trainable than fine-tuning or RL. We encourage you to try it out and see for yourself!
