Context windows grow, agents drift: PetsApp CEO to demo prompt ablation live
dscape · x · 2026-09-03
Lisbon AI event preview: PetsApp co-founder and CEO Thomjen Ko will live-dissect his own company's prompt architecture, arguing that the bigger the context window, the less reliable the agent gets — key instructions quietly lose their grip, a failure mode he calls "instruction drift".
Highlights:
- PetsApp runs AI copilots across hundreds of vet clinics — a production-grade case study
- He'll decompose prompts into competing foci, run ablation tests, and restructure prompts to hold critical instructions
- Ko is a Cambridge-trained vet, 2024 RCVS Impact Award winner, and creator of the open-source Focal Prompt toolkit
