AI Tinkerers Tokyo - Toranomon Meetup - February 19, 2026 

AI Tinkerers is the curated builders’ network for engineers, founders, and researchers focused on shipping real AI systems. We are a high-trust room for candid technical work—where code beats decks and demos replace theory.

Join us for our third meetup in Toranomon, Minato, Tokyo. We are convening 50 active builders to trade breakthroughs and dissect the implementation details of what’s being built right now, from specialized agentic coding models to new low-cost, high-performance inference platforms.

Registration is required and space is highly limited. Please complete the form above ↑.

Live Demos: Architecture, Trade-offs, and What Broke

We are looking for short, technical show-and-tell presentations. This is a stage for builders, by builders. We want to see your messy experiments, creative hacks, and technical discoveries in action.

Your 8-minute demo should answer: “How did you build this interesting thing?” not “Why should someone use this product?”

We prioritize:

• Live code walkthroughs, not slides.
• Deep implementation notes, not product pitches.
• Novel workflows, agentic setups, and context-engineering trade-offs.
• A respectful place to share unfinished work.

🎤 Submit Your Demo Proposal

If you are actively building and ready to pop the hood on your project, we encourage you to apply now. Presenters are prioritized for attendance.
