Samuel Colvin opens the first Evals London.
Samuel created Pydantic and now runs the company behind Pydantic AI and Logfire. His keynote is about evaluation and prompt optimization.
After the talk we break into small discussion groups. Bring the eval problem you haven't cracked yet, say a judge you only half trust, or a test set that quietly stopped catching regressions.
Who should come: engineers and data scientists building on LLMs, product people who own AI quality, and researchers. No sales pitches, from the stage or in the groups.
Evals London is the sibling of evals.cz, which has run four meetups in Prague since February. All filled up and ran waitlists. Places here are limited too, so if you register and your plans change, please cancel so someone on the waitlist gets your spot.
Hosted by Dawn Capital, Europe's leading specialist B2B software investor, at their Soho office. Catering kindly sponsored by Pydantic.
Check-in opens at 18:00 in the lobby of Ilona Rose House. Building security needs your full name in advance, so please register with your first and last name. By registering you agree to Dawn Capital's event terms: https://drive.google.com/file/d/1u1i2WKT0NeoV-YslA-tcN4-xVO5CYhXv/view
