From APIs to Agents: Control, Identity, and What Breaks Along the Way
From APIs to Agents: Control, Identity, and What Breaks Along the Way
Riverty Tech Night in collaboration with KI Park and cloud ahead Most of what we've built over the last \~15–20 years assumes a static frame of reference: Apps talk to services over APIs. You know who's calling what, you can stick a gateway in front of it, apply some policy, and move on. Agents don't really fit that model. They don't just call an API and return. They decide what to do, call a tool, look at the result, call something else, maybe involve another agent, loop through an LLM a few times… all the while, doing onbehalf of the user, with permissions that aren't always obvious. It's not always clear who is actually doing something. It's not obvious what the full execution path looks like. And the access control models we're used to — user → service, service → service fall part. We'll dig into what actually breaks when you start wiring agents into real systems, especially around identity and access control. Things like: \- how \(or if\) you assign identity to an agent \- what it means for an agent to act "on behalf of" someone \- how you enforce policy when the flow isn't predefined \- and how you get any kind of visibility into what just happened We'll also look at some of the patterns starting to emerge: agents talking to other agents, tools being invoked dynamically, and why a mediation layer (ie, agentgateway) must be built from the ground up with this in mind. \-\-\-\-\-\- Speaker \-\-\-\-\-\- Christian Posta ([Solo.io](http://solo.io/)) Christian is a globally recognized expert in cloud-native architecture, service mesh, and distributed systems. As Global Field CTO at [Solo.io,](http://solo.io,/) he works with enterprises to design and implement next-generation platforms—and is now at the forefront of AI-native infrastructure and agent systems. \-\-\-\-\-\- Who should attend? \-\-\-\-\-\- This meetup is for people who are building or thinking about the next generation of enterprise systems: Platform engineers and architects, Cloud-native practitioners, AI engineers working with agents and LLMs, Anyone exploring how AI changes system design \-\-\-\-\-\- How to join \-\-\-\-\-\-\- This time, the meetup will be in the premises of Riverty in Kantstrasse 17, Berlin (4th Floor of Living Berlin mall). Riverty will provide pizza and drinks. Please bring your ID as you will need to sign an NDA (we are a regulated entity).
BLISS x juna.ai Workshop: Open-Ended Algorithm Discovery with LLMs
BLISS x juna.ai Workshop: Open-Ended Algorithm Discovery with LLMs
**⚠️ IMPORTANT: REGISTRATION MANDATORY ⚠️** Registration on **Luma** is **REQUIRED** to attend this event. **Link: https://luma.com/7zfk3orp?utm_source=meetup** Your registration is subject to host approval. You must complete the registration process on lu.ma to receive the full event location details and confirmation of your attendance. **Please note: Without approved registration on Luma, you will NOT be able to access the event location or attend.** We are excited to host a **BLISS x juna.ai workshop** featuring **Dr. Nima Siboni (senior RL Engineer)**, who will guide us through an interactive session on algorithm discovery with LLMs. **​​​ Title: The Heuristic Scientist: Open-Ended Algorithm Discovery with LLMs** **📅 Date: 03.06.2026** **🕕 Time: 18:00** 📍 Location: TU Berlin Marchstrasse 23 [Room 0.011] ​​​The session will last around 2 hours, followed by a networking session with juna.ai and fellow AI enthusiasts (and free pizza!🍕). Bring your laptop! **​Abstract:** Large language models are increasingly useful not only for writing code, but for exploring the space of possible algorithms. In this hands-on workshop, we will look at how LLMs can act as “heuristic scientists”: generating candidate strategies, turning ideas into executable code, testing them against concrete objectives, and refining them through feedback. The workshop centers on the general discovery loop behind LLM-assisted heuristic generation. Participants will learn how to structure problems for algorithm discovery, prompt models to propose interpretable heuristics, evaluate those heuristics with simulations or benchmarks, and use the results to guide further search. We will also discuss when simple prompting is enough, when training or fine-tuning may help, and how to keep generated heuristics understandable, testable, and auditable. ​By the end of the session, participants will have built a small discovery loop of their own and will understand the practical trade-offs involved in using LLMs for open-ended algorithm discovery: creativity versus control, exploration versus verification, and automation versus human judgment. ​ **⚡ FINAL REMINDER ⚡** **You MUST register and be approved on Luma to attend. The event location will only be visible after your registration is confirmed by the host. Link: https://luma.com/7zfk3orp?utm_source=meetup** *** We are **BLISS e.V.**, Berlin’s AI community connecting like-minded individuals passionate about machine learning and data science.

PBerg engineers - monthly meetup
PBerg engineers - monthly meetup
**This is 100% non-profit. The 15€ sign up fee for everyone is only to minimize last-minute cancellations. The total sum goes to a bar-tap that everyone can use to order drinks until the amount is used up. ‼️NO REFUNDS‼️** **‼️Please don't just show up without RSVPing here and paying the 15€. We have a separate room that has limited capacity and a specific drinks agreement with the bar - so splitting up the bill won't become a mess.‼️** **Small update on how your money get's used from May 2024 onwards:** As of this month, meetup.com has started charging me 34€ instead of 16€ per month. I've decided to distribute this fee evenly among all us participants every month. Example: In the last 12 meetups, the average number of attendees was 17. With 17 attendees I would effectively collect 230€ (after fees). I would now substract 34€ leaving us with 196€ that go to the bar. 15% get's tipped to the wait staff, in this case 30€, leaving us with 166€ effectively to order drinks. Hope everyone is cool with this system. :) Website: https://www.pberg-engineers.me WhatsApp groups: Please come and join us on WhatsApp! \- "PBerg Engineers \- NEWS" \- Only organizers can post announcements or polls \-\> https://chat\.whatsapp\.com/EqMJMmlCZO6LOOfAoG4yTj \- "PBerg Engineers \- DISCUSS" \- Everyone can post \-\> https://chat\.whatsapp\.com/LPuo76J83gF6IZMLUcM4u2 Please join those groups now if you're interested. :) All skill/education-levels welcome! :) Lightning Talks: \- TBD We'll also have a brief "Jobs: Lost & Found section". **Location:** From the street you will have to enter the right hand Cafe Chagall (yes, there are 2). Then, you go upstairs and our private room is in the far end corner of the building. We are a relaxed, non-formal meetup of like-minded software engineers who want to always keep learning and want to meet in physical reality over a drink or two.

Berlin Sprachcafé. Learn and practise German easily (A1-A2)
The Language Café is primarily aimed at people who are struggling with their mental health which can make it hard to go to regular courses. We want to create a safe space for everyone to learn and practise without pressure. Everyone is welcome! Please try to be on time so we can all get started together :) We mainly practise on a beginner/lower intermediate level and adapt to everyone's prior level of German. The Language Café will focus on teaching you the most important words and phrases and basic grammar in German. The content of the course is adapted to real life. (everyday life in Germany, dealing with authorities, etc.) We will cover different topics every week and you can join us anytime, since the topics do not necessarily build on each other. The Sprachcafé is for free. \*If you cannot make it please cancel your participation so someone else from the waiting list can join, thank you!\* \| \| \| \|

We've turned the entire learning experience into ***Comprehensible Input* through both simplified and traditional manga** with support for **Zhuyin**, **Pinyin**, **flashcards**, **audio**, **direct translation**, an integrated dictionary. We also specifically design region-specific language to reflect real-life usage in both **mainland Chinese Mandarin** and **Taiwanese Mandarin**, allowing you to naturally compare and explore the differences between the two, so you don’t end up saying something that makes perfect sense in Beijing, but gets you funny looks in Taipei 😏. Now, together with our good friend Matthias from **[Gemeinsam Chinesisch & Deutsch lernen](https://www.meetup.com/gemeinsam-mandarin-chinesisch-und-deutsch-lernen/events/308204343/?eventOrigin=group_upcoming_events),** we’re inviting you to our very first **in-person Mandarin Learner Meetup in Berlin** together! All levels are welcome, from beginners to advanced learners. Just come hang out, share your stories, laugh at our tone mistakes! As a community, we can learn from each other and turn Mandarin into a piece of cake! 🍰 **Come and join us!** 📱 App: [Wehanzi.com](https://wehanzi.com/) 📸 Free bite-sized resources: [Instagram](https://www.instagram.com/wehanzi/) 📚 More free tools: [wehanzi.app/menu](https://wehanzi.app/menu) **📍ABOUT THE MEETING SPOT** Please note that we will meet HERE, on the 3 wooden tree benches slightly left of the main entrance gate of Tempelhofer Feld: [https://maps.app.goo.gl/L8SuKJxoLLa8hXCdA](https://maps.app.goo.gl/L8SuKJxoLLa8hXCdA) We'll meet at the meeting spot first and then - depending on the weather - decide as a group to either walk around Tempelhofer Feld or go to a closeby restaurant to warm up and chat.

You can find more information here: [Digitale Leute Summit 2026](https://www.digitale-leute.de/summit/26/ "https://www.digitale-leute.de/summit/26/") **About Digitale Leute** Digitale Leute has always been about one thing: bringing together the people who shape digital products. The thinkers, the builders, the ones who care deeply about how technology is made and why it matters. Over the years, our community has grown – but we’ve missed the magic that only happens when you’re in the same room, sharing ideas, swapping stories, and sparking conversations that no Slack channel can replicate. So we decided: it’s time to bring our meetups back. **About SAP in Berlin** Located in the heart of European innovation, [SAP in Berlin](https://www.sap.com/germany/about/berlin.html "https://www.sap.com/germany/about/berlin.html") combines the power of a global company with the strength of a unique local ecosystem – we attract talent, shape SAP‘s image as a front-runner of innovation, and foster our position as market leader for enterprise application software in Berlin.
