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.

Creating world class AI experiences requires extensive prompt testing, fast deployment and detailed production monitor. Luckily, Vellum provides all three in a slick package. The Vellum team is also lightning fast to add features, I asked for 3 features and they shipped all three within 24 hours!

Founder, Feeling Good App

Aman Raghuvanshi

I love the ability to compare OpenAI and Anthropic next to open source models like Dolly. Open source models keep getting better, I’m excited to use the platform to find the right model for the job

Co-Founder & CEO, Pyq

Jonathan Gray

We’ve migrated our prompt creation and editing workflows to Vellum. The platform makes it easy for multiple people at Encore to collaborate on prompts (including non technical people) and make sure we can reliably update production traffic.

Founder & CEO, Encore

Edvin Fernqvist

Having a really good time using Vellum - makes it easy to deploy and look for errors. After identifying the error, it was also easy to “patch” it in the UI by updating the prompt to return data differently. Back-testing on previously submitted prompts helped confirm nothing else broke.

Vellum gives me the peace of mind that I can always debug my production LLM traffic if needed. The UI is clean to observe any abnormalities and making changes without breaking existing behavior is a breeze!

Co-Founder & CEO, Uberduck

Michael Zhao

Our engineering team just started using Vellum and we’re already seeing the productivity gains! The ability to compare model providers side by side was a game-changer in building one of our first AI features

Co-Founder & CTO, Vimcal

Jasen Lew

We’ve worked closely with the Vellum team and built a complex AI implementation tailored to our use case. The test suites and chat mode functionality in Vellum's Prompt Engineering environment were particularly helpful in finalizing our prompts. The team really cares about providing a successful outcome to us.
