Evaluate Prompts at Scale

Progress past the “vibe check” and add some engineering rigor with quantitative evaluation. Use popular eval metrics or define your own.

Deploy Changes With Confidence

Github-style release management for your prompts & prompt chains. Datadog-style monitoring and observability. A tight feedback loop across it all – catch edge-cases in prod and add to your eval set.

The Four Pillars of Building LLM Applications

Whether you use Vellum or not, building a production-grade AI application requires investment in four key areas.

Your data is your moat. Feed your prompts data unique to your company and customers to create personalized experiences.

Rapid iteration is crucial. Quickly iterate on prompts, compare different models side-by-side, test out new prompt chains, and evaluate your outputs at scale.

GPT-4, meet software development best practices. GenAI development still requires good ol’ fashioned unit testing, version control, release management, and monitoring.

Tighten those feedback loops. Catch edge-cases in production, add them to your eval set, and iterate until it passes. Replay old requests against new models to gain confidence before shipping.

Full Stack Engineer @ Lavender

Eric Lee

Prior to our partnership with Vellum, a prototype would take 3-4 designers and software engineers a couple weeks to create a prompt, compare across models, fine tune, deploy to an APi and then build a frontend for. Now, many of our prototypes are bouilt within 1 week.
