Paper:
GEPA: Reflective Prompt Evolution Can Outperform Reinforcement Learning (ICLR 2026)
https://arxiv.org/pdf/2507.19457
The paper introduces GEPA, a highly efficient prompt optimizer that uses natural language reflection and Pareto-based search to adapt language models to complex tasks. It significantly outperforms reinforcement learning methods like GRPO and prior optimizers like MIPROv2 by requiring up to 35x fewer rollouts while achieving higher accuracy.

📍 Location & Registration

• We are welcomed at the inpeek AG office (Bogenschützenstrasse 9) in the PostParc building next to the train station.
• Although meetup.com limits the capacity to 10 registrations (we don't pay for additional capacity), the event is not limited. If you don't secure an ordinary spot, just join the waitlist, you'll still be very welcome! This helps us plan and know how many people to expect.
• The event will be held in english
