Secure Orchestration
Who is talking about what
Steffen Hausmann
LangChainTalk
How We Built it: LangSmith Engine
Abstract
Steffen will walk through LangSmith Engine—an agent that analyzes traces, identifies recurring failure patterns, and suggests concrete next steps. He’ll cover its architecture and how teams operationalize the agent-improvement loop.
Yixuan Xu
ETH AI CenterTalk
From Open Model to Open Multimodal: Building Apertus 1.5
Abstract
Apertus 1.5 extends the open language-model initiative into a fully open multimodal foundation model spanning vision and audio. Its multimodal understanding comes directly from the LLM backbone, trained on discrete multimodal tokens rather than external encoders. The talk covers the team, journey, key ideas, and lessons learned.
Edgar Kussberg
SonarTalk
Now We Keep Agents Honest
Abstract
Rebuilding a 15-year-old code-analysis company for the agentic era—and the three things that bit the team along the way.
Max Rumpf
SIDTalk
How to Train a Frontier LLM with RL
Abstract
RL has driven many recent LLM intelligence gains, but its techniques remain poorly understood. Based on training SID-1, an agentic search model, this talk explores the infrastructure, challenges, data, and practical limits of reinforcement learning for frontier LLMs.
Roman Ackermann
Auth0Talk
Securing AI Agents — Workshop
Abstract
AI agents can call APIs, execute workflows, and act on behalf of users. But who controls what those agents are actually allowed to do? Join Roman for a hands-on workshop exploring how Auth0 secures AI-powered systems and automated workflows.

Details
AI agents increasingly call APIs, execute workflows, and act on behalf of users. This meetup brings together practical lessons from building agent-improvement systems, open multimodal models, agentic code analysis, reinforcement learning, and secure agent workflows.
