Abstract We ran everything in one Azure subscription. Leads and sales, installations and steering energy systems. Everyone had access. Most resources were created manually. It was unclear who owned what. As the tech org grew from 100 to 300 people, reinventing security and scaling individually stopped working. We'll cover how we approached platform building as gardeners rather than architects: observing what already works, replicating it, and letting rituals emerge before encoding them. We'll look at some mistakes we made along the way and what we learned from each. *Dayana Mick* **It works… but no one understands it: The hidden problem in DevOps** For several years, I kept asking the same question to senior developers, staff engineers, and mentors: “What is a build?” I rarely got a clear answer. Not because people didn’t know, but because the mental model had faded somewhere between Terraform, Ansible, Kubernetes, and “just run this command.” At some point, I realized I could run pipelines, deploy services, and fix things just enough to move forward, but explaining what was actually happening was much harder. And I was not the only one. This talk is about a pattern I’ve seen across every company I’ve worked at. Systems that work, but are not really understood. Teams running platform commands from memory. Platform teams becoming bottlenecks. Incidents where even experienced engineers hesitate. And situations where people rely on tools without a clear sense of what is actually happening underneath. With AI, this is only accelerating. This is a talk for anyone who has ever copy-pasted a command, watched it work, and decided not to ask further questions. It is especially relevant for junior and mid-level engineers navigating DevOps complexity, and for teams who are trying to scale tooling without losing shared understanding.

Are you a software engineer, product owner, or HR professional navigating the shift toward an AI-driven world? Join us for an in-person meetup in Berlin, where we bridge the gap between high-stakes AI implementation and the rapidly evolving European labor market. 🙌 Special thanks to our host, Blue Card Agency, for supporting the community and providing the venue for this event! 🔔 Agenda 🔹 Welcome & Intro A brief opening by our hosts from Blue Card Agency. 🔹 Talk 1: "Beyond the LLM Hype: Process Discovery is the Real Bottleneck" Speaker: Patrick Bunk, Co-Founder & Lead Architect Automating 120k PDF forms a year in a regulated manufacturing environment isn't just about "reading text" — it's about surviving the messy reality of human logic. In this talk, we’ll dive into a real production case where the biggest challenge wasn't the model, but the "uncomfortable truth": rules live in people’s heads, exceptions conflict, and "correct" is negotiable until you write it down. 🔹 Talk 2: "The Present and Future of the Labor Market with AI" Speaker: Milana Alenina, HR Partner How is AI actually changing the way companies hire and value work? We’ll explore the structural shifts happening right now in the European market, from the need for candidates to be "machine-readable" to how organizations are redesigning themselves to fit the new reality. ⚡️ What’s in it for you? We’re skipping the surface-level AI hype to talk about what’s actually happening in the trenches. Come for the real-world war stories of automating regulated workflows, stay for a brutally honest look at how AI is rewriting the rules of recruitment and organizational value in Europe. It's a chance to cut through the "vibes" and see the actual mechanics of the shift — followed by drinks and networking with fellow builders and strategists. 📌 Attendance is free, but spots are limited — register now to save yours! 📅 Date: 21st of April 📍 Location: Ziegelstraße 2, Berlin 🎤 About the Speakers: Patrick Bunk, Co-Founder & Lead Architect — Expert in building robust AI pipelines and navigating the complexities of high-stakes automation. Milana Alenina, HR Partner with 11+ years of experience who experiments with AI tools across various HR functions.

We're back and excited to feature **Nouamane Tazi**, who is currently a Research Engineer at **HuggingFace** and will discuss "**Scaling LLM Training to Thousands of GPUs**", lasting approximately 45 minutes. After the talk, seize the opportunity to connect with fellow AI enthusiasts to share ideas and questions while enjoying free drinks and pizza. **Door close by 7.15pm, so please come early! Also, "attend"ing (RSVP) here on Meetup is strictly necessary to be guaranteed entry.** Please note that Meetup has recently been quite keen on promoting its Plus program. However, you are not obligated to purchase it, as both our events and the platform remain free. **Who is this event for?** This event is open to everyone interested in state-of-the-art AI research. We especially design it for students, PhD candidates, academic researchers, and industry professionals with a research focus in machine learning. **Abstract**: Training large language models at scale introduces a cascade of systems bottlenecks absent at smaller scales: from communication overhead and memory fragmentation to subtle numerical instabilities that surface only across thousands of devices. This talk covers the practical design choices behind scaling LLM training to thousands of GPUs: what parallelism strategies work (and when they break), how to keep training runs efficient and stable, and the engineering trade-offs that shape modern pretraining infrastructure. The presentation aims to be accessible to a broad ML audience, drawing on real-world experience from large-scale open-source training runs at Hugging Face. **Bio**: Nouamane Tazi is a Machine Learning Research Engineer at Hugging Face, specializing in training and scaling large language models. He is a co-author of SmolLM3 and The Ultra Scale Playbook, and his research spans NLP, deep learning, and scalable AI infrastructure. We are [BLISS](https://bliss.berlin/) e.V., the **AI** **organization** in Berlin that **connects like-minded individuals** who share great interest and passion for the field of machine learning. This summer 2026, we will, again, host an exciting speaker series on site in Berlin, featuring excellent researchers from cohere, ETH Zürich, University of Oxford, HuggingFace, and Stanford University.

Join our in-person meetup on April 24th to hear talks from experts on cutting-edge topics across AI, ML, and computer vision. **[Register to reserve your seat.](https://voxel51.com/events/berlin-ai-ml-and-computer-vision-meetup-april-24-2026)** Space is limited! **Date, Time and Location** Apr 24, 2026 5:30 PM - 8:30 PM [MotionLab](https://motionlab.berlin/) Bouchéstraße 12/Halle 20 12435 Berlin **Kaputt: A Large-Scale Dataset for Visual Defect Detection** We present a novel large-scale dataset for defect detection in a logistics setting. Recent work on industrial anomaly detection has primarily focused on manufacturing scenarios with highly controlled poses and a limited number of object categories. Existing benchmarks like MVTec-AD (Bergmann et al., 2021) and VisA (Zou et al., 2022) have reached saturation, with state-of-the-art methods achieving up to 99.9% AUROC scores. In contrast to manufacturing, anomaly detection in retail logistics faces new challenges, particularly in the diversity and variability of object pose and appearance. Leading anomaly detection methods fall short when applied to this new setting. To bridge this gap, we introduce a new benchmark that overcomes the current limitations of existing datasets. With over 230,000 images (and more than 29,000 defective instances), it is 40 times larger than MVTec and contains more than 48,000 distinct objects. To validate the difficulty of the problem, we conduct an extensive evaluation of multiple state-of-the-art anomaly detection methods, demonstrating that they do not surpass 56.96% AUROC on our dataset. Further qualitative analysis confirms that existing methods struggle to leverage normal samples under heavy pose and appearance variation. With our large-scale dataset, we set a new benchmark and encourage future research towards solving this challenging problem in retail logistics anomaly detection. The dataset is available for download under [https://www.kaputt-dataset.com](https://www.kaputt-dataset.com). *About the Speaker* [Sebastian Höfer](https://www.linkedin.com/in/sebastian-h%C3%B6fer-891178121/) is an Applied Science Manager at Amazon Fulfillment Technologies & Robotics, leading machine learning and computer vision research for large-scale robotics and warehouse automation. He received his PhD from the Robotics & Biology Lab at TU Berlin, focusing on Sim2Real transfer and robotic perception. His recent work, “Kaputt: A Large-Scale Dataset for Visual Defect Detection” (ICCV 2025) [37], established a major benchmark for industrial anomaly detection, reflecting his expertise at the intersection of academic research and real-world deployment. **Data Foundations for Vision-Language-Action Models** Model architectures get the papers, but data decides whether robots actually work. This talk introduces VLAs from a data-centric perspective: what makes robot datasets fundamentally different from image classification or video understanding, how the field is organizing its data (Open X-Embodiment, LeRobot, RLDS), and what evaluation benchmarks actually measure. We'll examine the unique challenges such as temporal structure, proprioceptive signals, and heterogeneity in embodiment, and discuss why addressing them matters more than the next architectural innovation. *About the Speaker* [Harpreet Sahota](https://www.linkedin.com/in/harpreetsahota204/) is a hacker-in-residence and machine learning engineer with a passion for deep learning and generative AI. He’s got a deep interest in VLMs, Visual Agents, Document AI, and Physical AI. **Most AI Agents Are Broken. Let’s Fix That** AI agents are having a moment, but most of them are little more than fragile prototypes that break under pressure. Together, we’ll explore why so many agentic systems fail in practice, and how to fix that with real engineering principles. In this talk, you’ll learn how to build agents that are modular, observable, and ready for production. If you’re tired of shiny agent demos that don't deliver, this talk is your blueprint for building agents that actually work. *About the Speaker* [Bilge Yücel](https://www.linkedin.com/in/bilge-yucel/) is a Senior Developer Relations Engineer at deepset, helping developers build agentic AI apps with Haystack. Passionate about AI, she makes complex concepts approachable through hands-on tutorials, both online and at real-life events. **Operationalizing Computer Vision for Overhead Lines: Beyond the Demo** At first glance, visual inspection of high-voltage power lines seems straightforward: collect imagery, run one or two AI models, and report the findings. In practice, moving beyond a proof of concept reveals a range of issues that can make or break a campaign. Common concerns include data quality and coverage, scarcity of the most relevant cases and abundance everywhere else, variations in pylon geometry and asset types across regions, calibration and GIS alignment challenges, and a long tail of edge cases that emerge in real-world operations. This talk introduces Siemens Energy’s end-to-end overhead line inspection solution and shares key learnings from inspecting more than 10,000 km of power lines for real customers across several continents. We will show how raw 2D/3D data is transformed into structured information, delivering insights into asset inventory as well as defects, and supporting maintenance and planning decisions for critical infrastructure. The focus is on the combination of algorithmic building blocks and scalable processing, designed for robustness and consistency at scale, where even low error rates can become operationally significant. *About the Speaker* [Stefan Wakolbinger](https://www.linkedin.com/in/stefan-wakolbinger-aa0ba874/) is the Development Team Lead for AI & Analytics at SIEAERO, Siemens Energy's digital powerline inspection service. He leads the development of cutting-edge AI and analytics solutions that transform aerial powerline inspection through multi-sensor technology. His team creates digital twins of powerline infrastructure, automates fault detection, and monitors vegetation management—making powerline inspection safer, more precise, and more efficient. Stefan has been driving innovation in this role since September 2022. **Search your video library like a database** Drop in YouTube URLs or upload files and query content four ways: exact keyword matching, semantic search across transcripts, visual scene search via SigLIP2, and LLM-generated answers that synthesise across segments.

About his keynote: "Data access and reuse are still unsolved, and AI agents are making it worse. This talk goes deeper into that problem: AI agents depend on reliable context (data, features, intermediate state) to make correct decisions. In practice, this context is tied to specific pipelines or infrastructure, leading to brittle systems when moving from prototype to production. I'll show how a plugin-based approach lets teams build deterministic context layers: separating what you compute from how you compute it, so the same feature definitions work on a laptop and in production. The talk includes a live demo where an AI agent discovers and queries data features programmatically. " **Behnaz Derakhshani: *"What If I Started Today?

Attendees will learn how to leverage these integrated features to build a more resilient and transparent developer experience. Discover how to transform your Datadog instance into a strategic asset for your platform’s success. **📅 19:15 - Logs as a First-Class Citizen - How Lightspeed Commerce evolved logs to unlock the full power of Datadog** **(30 min.)** **🎙️**Speaker: Rein Martha, Staff Software Engineer, Lightspeed Commerce When Lightspeed started with Datadog, we didn't begin with traces or metrics — we began with evolving our logs. Raw, unstructured, and full of noise. The first step was making them worth keeping: trimming duplicates, removing what no one ever read, and transforming what remained into structured, queryable signals. That foundation changed everything. Once logs became first-class — with clean attributes, consistent structure, and a clear purpose for every line — the rest of the observability stack followed naturally. Monitors built on log queries. Dashboards that actually meant something on incidents. Metrics generated directly from log attributes, giving us long-term retention without the cost of keeping everything raw. **📅 19:45 - Best Practices for Alerting with Datadog (30 min.)** **🎙️**Speaker: Santiago Gomez Saez, Datadog ambassador & Principal Cloud Architect @ **[dxone](https://www.dx.one.gmbh/)** Operational excellence is the main objective of SRE teams. Focusing on alerting, this talk shares common pitfalls and best practices on how and when to alert when incidents occur.

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
