We are excited to feature **Marzieh Fadaee**, who is currently Head of Cohere Labs at **cohere** and will discuss "**Scaling LLMs Across Languages**", 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**: Scaling has driven progress in language models, but improvements in peak performance often fail to translate across languages. In this talk, I show how multilingual models expose the limits of scale and highlight the importance of balanced performance. I argue for a shift from optimizing peaks to lifting the floor, through better data, design, and evaluation illustrated through Tiny Aya. **Bio**: Marzieh Fadaee is the Head of Cohere Labs, where she leads research on fundamental problems in artificial intelligence. Her work spans multilingual language models, data-efficient learning, model evaluation, and trustworthy AI, with a focus on building systems that are robust, inclusive, and globally impactful. She co-leads the Aya initiative that brought together over 3,000 collaborators worldwide to create the world's largest multilingual instruction dataset and the development of a series of state-of-the-art multilingual language and vision models. Before joining Cohere Labs, Marzieh was the Research Lead at Zeta Alpha Vector, where she pioneered innovative approaches to knowledge discovery and organization. She holds a PhD from the University of Amsterdam where she conducted foundational research on neural machine translation. Her research has been published in top venues such as NeurIPS, ACL, EMNLP, and ICLR, and she frequently serves as a mentor and advisor in the global AI research community. 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.

You built, you broke, and now you will learn! Agentic coders are a major breakthrough for developers, making work easier (then at times more challenging!) Think about how these tools evolved from providing simple code blocks to actively rewriting the code inside IDE. As we, developers, engineers and designers, who are still learning how to use them, we need to understand the reasoning behind these tools and follow some best practices. **Kiro Bootcamp - Learn from the Experts** In light of all these, we kept our promise and are happy to organize a half-day long Kiro Bootcamp for you. Thanks to **Rackspace Technology** we will be gathering in WeWork, inviting experts from AWS to introduce you Kiro, explain the critical parts, help with getting the most out of it. This is a hands-on workshop with a practical deep dive into starting-up, running and optimizing Kiro. You work through independent tasks that you can pick and choose from, learning how to build, deploy, and operate your ideas on Kiro IDE. By the end of the workshop, we aim that you understand how Kiro works, what things you have to take into account at spec-driven development, and how you can integrate your Kiro IDE to external and internal tools. This workshop is aimed at developers, designers, cloud specialists and product developers. While it is not necessary to have extensive knowledge on AI development, it is ideal that you install Kiro in your device and try to build some minor projects in advance. **When?** 5th of May\, Tuesday\,\| 12:00 \- 17:00 **Where?** WeWork - Stresemannstraße 123, 10963 Berlin **How?** Fill out this form to apply.

Join us for our next Berlin Collaborative Modelling session — a hands-on workshop where we'll build a Context Map from scratch. Context Maps make the big picture of a system explicit: which bounded contexts exist, how they relate to each other, and where the friction, dependencies, and power dynamics between teams actually live. They help you make better decisions about integration strategies, team ownership, and where to invest in clean boundaries versus where to accept pragmatic compromise. To get there, we'll use Event Storming as our starting point — laying out domain events to discover natural clusters of behavior, then drawing boundaries around them to identify candidate bounded contexts and subdomains. From there, we'll sketch out the relationships between contexts and discuss what patterns like Customer/Supplier, Conformist, or Anti-Corruption Layer look like in practice. What to expect: This is a collaborative, stickies-on-the-wall kind of evening. No laptops needed, no prior DDD experience required — just curiosity about how to make sense of complex systems. We'll work through a shared example domain together, so everyone starts from the same place.

### **🌿 Watercolour Herbarium: A Sensory Workshop** Do you know which herbs boost memory? Which ones calm your body, support digestion, or help you sleep? Join us for a unique 4-day watercolour journey where art meets nature, observation, and everyday wisdom. **In this workshop, we will create our own illustrated herbarium — a personal catalogue of plants — while working directly from real, fresh herbs from my little balcony garden.** You’ll learn how to observe their shapes, textures, and colours, and translate them into delicate watercolour studies. But this is more than painting. Each day, we’ll explore a different selection of herbs like oregano, rosemary, mint, basil and more — learning how they grow, what they’re traditionally used for, and how they can support your body and wellbeing. **We’ll touch them, smell them, paint them… and even taste them in teas and infusions,** engaging all our senses to truly connect with each plant. ✨ What to expect: * Guided watercolour sessions (all levels welcome) * Real herbs to observe and paint from life * Gentle introduction to herbal knowledge & home remedies * A growing collection of your own illustrated herbarium * A calm, sensory, and inspiring atmosphere * Tips about how to grow these herbs at home during this spring By the end of the 4 days, you’ll leave not only with a beautiful series of paintings, but also with a deeper understanding of the plants around you — and how they can become part of your everyday rituals. The workshop includes **four classes**, but you’re also welcome to join individual sessions (when available). To receive the registration form and full details, please contact: 📩 **hola.berlinartclub@gmail.com** **When:** Tuesday 5 - 12 - 19 - 26 May From 6 to 7.30 PM **Where:** Friedrichshain, Berlin (You will receive the exact address by e-mail) **Price:** 85€ for the whole month (4 classes) Single class 25€ / Paypal & Bank Transfer **Material:** You will need a watercolour set, watercolour paper (or sketchbook) and brushes.

The common wisdom goes: data is either transactional or analytical, and workloads are OLTP and OLAP-shaped to match. The reality of generating and using data is different, and often we need a bit of both. The pg_lake extension brings OLAP workloads to OLTP Postgres. This talk will explore the pg_lake extension, including how to build it, and demos of using it with modern data workloads in object storage like Amazon S3. We’ll create simple data pipelines with no ETL and high performance analytics. **I Didn't Know Postgres Could Do That!** by Robert Treat, Principal Database Engineer at AWS and PostgreSQL Major Contributor. PostgreSQL is often thought of as "The Database for DBAs", but what more and more developers are finding out is that what makes Postgres "The Worlds Most Advanced Open Source Database" is its wide array of features, many of which are really geared towards engineers building applications on top of Postgres. In this talk, we'll look at some of the features in Postgres you may not have seen in other database systems, and talk about how you can make use of those features in your applications. Queries, indexing, data types, and more will all be up for discussion as we show you examples of just what Postgres can do.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.
