DSL hosts AI Tinkerers HK – Deep Dive
Dim Sum Labs partnered with AI Tinkerers HK to bring Deep Dives highlighting developers who are working in the GenAI/ML/CV in Hong Kong. The talk was hosted by Iulian Arcus, an events coordinator at Dim Sum Labs and a co-organiser at AI Tinkerers HK. Today we’ve had two talks: The first by Way Fai Godfrey Cheng who presented his work on designing a Neural Network based Snooker game tracking for a local club. He took us through his hardware purchase, labeling fails and wins, and the training pitfalls he faced. MobileNet-SSD won over Yolo for high framerate and local inference on a Nano Jetson. The second speaker Devansh Gandhi presented his approach to simulating Hong Kong opinions on a variety of topics. He starts by generating various personas with names, age, income brackets, and general life information. This seeds the LLM (Microsoft’s phi-3.5-mini) to answer from the perspective of the persona. However the answers weren’t very diverse. The next step was aligning the LLM using QLORA finetuning using local biases from Hofstede’s Six Cultural Dimensions . The fine tune called (Dlab-852-Mini) was evaluated against the mean of Hofstede’s results with some matching in certain categories but not all. Devansh then shows the generated answers for personas related to the then hot topic of changing the senior discount for public transport. Finally he compares the results with Deepseek which shows very small standard deviations in its personas, likely due to its training data and additional API guardrails. Comments from the public mentioned that phi-3.5 was trained on books only which is why the original evaluation answers felt overly formal. The session achieved its goal: deep dive into the details of the application, questions delved deeper into possible alternatives and insights from attendees.
The 2026 Meetup roadmap—Building on our 2025 momentum
As 2025 comes to a close, we’re reflecting on a transformative year for Meetup. For months, our focus has been on making Meetup more reliable and efficient for organizers, and more inviting and intuitive for the entire community. To that end, we introduced a series of improvements to the platform, including public group reviews, direct responses to individual reviews, and automatic events in Google Calendar . We cover these updates and more here on our blog . Since then, we’ve been working hard on an exciting new product roadmap, which includes three key initiatives: Launch a modern and delightful new Mobile experience Make community-building effortless Give members greater confidence to show up and connect With the new Mobile experience live as of December 18, 2025, we’re turning our focus to the other two initiatives, with product developments already underway for 2026. Below, we go into more detail about each of the three initiatives—why we believe they’re important for the community, and how we’re pursuing them. Launch a modern and delightful new Mobile experience In 2025 we gave Meetup its most significant redesign in years, aiming to create a more modern and welcoming experience for all members and organizers—both current and those joining now. As we explain in this article , our goal was to give the platform a more inspiring and human feel, while keeping its core identity and functionality fully intact. We rolled out the new design (one of our main roadmap points) on Meetup Web back in October, and have just finalized the Mobile design this December. All of this momentum sets the stage for a 2026 focused on deeper connection, easier organizing, and a more supported member experience. Make community-building effortless The Meetup community is unique in how it grows: With 75% of organizers having started as members, people don’t just find welcoming spaces here—they help create them. In 2025 we built on this strength with Meetup Starter , our free plan that eases first-time organizers into event creation. In 2026, we’re focusing even more on fostering organic community building by bringing organizers and members closer together and making the transition from member to organizer as intuitive as possible. Here are a few such updates we’re planning to release in the coming months: A single unified app. Next year, organizers and members will have one shared home on Meetup. No more separate Organizer app—just a unified experience that puts organizers closer to the member perspective and makes it easier to stay connected to their communities. Simplified attendance tracking. QR-code check-ins will provide a faster and more accurate way to track attendance, reducing confusion at the door and ensuring a smoother start to every event. With such targeted improvements, we believe the path to organizing events and building communities on Meetup will become noticeably smoother and more intuitive. Give members greater confidence to show up and connect Meeting new people can be exciting, but it can also feel daunting. Already having a sense of who you’ll meet—their age, background, what interests you might share with them—can help a lot. In 2026, we’re introducing updates that will help members show up with confidence, including the following: Richer member profiles. Profiles will include more meaningful details and additional photos, helping members get a clearer sense of who they might meet and what they may already have in common. Super Organizer badge. We’re introducing a badge that recognizes organizers with the highest-quality groups—those with strong engagement, activity, and ratings—to make it easier than ever for members to identify standout communities. Experimental connection tools. We plan to trial new ways to help members connect outside of events, aiming to ease social anxiety and create space for new friendships to flourish. Moving forward together As we head into 2026, our early focus will be on improving the moments that matter most across the entire Meetup experience—before, during, and after an event. We’ve shared just a few highlights here, but there’s much more already in the works to support these moments. As always, we’ll keep listening to our organizers and members as we decide what to focus on next, and as we explore new ways Meetup can help people feel more connected. Thank you for being part of this community, and for helping us shape what comes next at Meetup! — Chiara The post The 2026 Meetup roadmap—Building on our 2025 momentum appeared first on Meetup Blog .
