Finally understand embeddings - And you will never have to search for the right emoji again
Embeddings are the foundation of how Large Language Models understand the world. Yet, when you try to read about them, you are bombarded with scary words like tensors, matrices, and multi-head attention. No need! Let's try and actually get a grip on how embeddings work. Join Elias Schecke and Dennis Schulz to understand how powerful embeddings can be as a tool for Natural Language Processing. Of course, they will bring their own demo application that adds a correct, fitting, and tasteful emoji to whatever chat message you feed it with - so your parents will finally be able to pick the correct emoji when writing to you.
Elias and Dennis will explain why they translate language into high-dimensional vectors. Then, they will build a sample application for emoji search, explaining semantic search, finetuning, and multi-modal embeddings along the way. They will also give an overview over benchmarks and how to scale your semantic search application.

Automating the Web: TNG's Web AI Navigator
What if a digital teammate could click, read, and type across the web and your internal tools - so you don’t have to? Meet TWAIN, TNG’s Web AI Navigator: a multi-agent system that actually gets work done. From filing and updating Jira issues, digesting Confluence pages, and booking travel to triaging and replying to emails, TWAIN autonomously navigates real workflows instead of stopping at suggestions.
Dr. Maxim Stykow and Alexander zur Bonsen will share how they built it and what they learned the hard way. Under the hood, TWAIN combines browser automation, internal API access, and LLM planning, with the Model Context Protocol (MCP) enabling a plug-and-play ecosystem of tools for “infinite” extensibility.
Join the talk for:
• Live, end-to-end demos of TWAIN handling tasks that usually take multiple tabs and many clicks.
• Architecture patterns for robust AI agents at work, not just in labs.
• Battle-tested solutions to messy realities: SSO/auth flows, flaky DOMs, context limits, rate limits, and error recovery.
• How they bake in privacy-first principles while keeping the experience conversational - and a little bit magical.
You’ll leave with practical patterns, gotchas to avoid, and checklists you can reuse to bring similar agents into your own environment. This talk is for engineers, architects, and product folks who want AI that moves the needle from “chat” to “ship”. Bring your questions and your toughest workflows.

Sparse Models are the future: A deep dive into Mixture-of-Experts
The limits of scalability have been reached. AI training compute has increased by 10^21 since AlexNet, but these models can’t just get bigger forever. The most powerful language models today use less than 10% of their parameters for any given token, achieving significant computational savings while maintaining high quality. The efficiency comes from Mixture-of-Experts (MoE) architectures, which route different inputs to specialized expert networks instead of activating all parameters, saving compute. Drawing from latest trillion-parameter model design choices, this talk will cover why sparse architectures through MoE represent the most viable path for efficient AI scaling in production systems.

Dirty trenches & clean code - What to learn from a telco’s Cloud-first strategy
OXG was founded in 2023 as subsidiary of Vodafone to build a fiber network telco as cleanly as possible: pulling fiber cables using a modern Cloud-first approach for the tech stack.
This worked - mostly. Today OXG employs a mixture of self-built and third-party components. While the glue components holding the proprietary business logic come as shiny, server-less, Cloud-native, fully-scripted one-click-deployment artifacts, like every other company OXG is still bound by reality.
Setting up some of the not-so-Cloud-native applications felt like smuggling a dinosaur onto a spaceship – complete with hard-coded passwords, expensive extra luggage, suspicious security findings, and a boarding process that involved three deployment pipelines and a lot of coffee.
This talk will give an overview of the ups and downs of the last two years including the reason why holding a gym membership is the same as having a backup & recovery plan.

Autonomie, Robotik, KI - und der Mensch
According to robotics research, robots are able to perform tasks autonomously in more and more contexts of action. With the help of artificial intelligence, robots can learn to adapt to different environments and challenges. We are then talking about artificially intelligent autonomous robots. How does this adaptive, technically autonomous behaviour of a robot relate to human autonomy, which we regard as a constitutive element of personhood?
This talk examines this question from the perspective of technology assessment. In which contexts does it make sense to allow autonomous robots to act instead of humans? When is collaboration between humans and robots the method of choice? And in what way does human autonomy meet technical autonomy in this collaboration? The different degrees of autonomy in autonomous driving can be used as an example here.

Conversational, Generative, Contextual: A framework for AI-era product design
The traditional user experience (UX) design paradigm is no longer applicable in the context of AI. It is not possible to design deterministic user flows when systems generate different outputs from identical inputs. Most AI failures aren’t model failures—they’re context failures.
This talk outlines pragmatic methods for designing AI-powered products, encompassing four pivotal dimensions: non-deterministic UX patterns, generative UI systems, context engineering workflows, and enterprise risk assessment. Learn about concrete methods for testing unpredictable systems, measuring effectiveness without traditional metrics, and communicating the design intent that makes or breaks AI implementations.
You’ll leave with an actionable framework, assessment tools, and design & communication patterns — moving beyond AI hype to systemic design practice.
