🥽 What is AI Tinkerers?
AI Tinkerers is a meetup designed exclusively for practitioners who possess technical, machine learning, and entrepreneurial backgrounds and are actively building and working with foundation models, such as large language models (LLMs) and generative AI. If you’re deeply passionate about creating LLM-enabled applications, have hands-on experience in building such systems, and are eager to connect with like-minded individuals who share your level of commitment, then this group is the perfect fit for you. With AI Tinkerers meetups taking place in multiple cities, we cater to a dedicated community of practitioners.
🌍 Who is this for?
👉 It’s AI Tinkerers, not AI enthusiasts. We screen attendance to active builders with a shared level of expertise in order to create a collaborative environment ideal for early-stage discovery and innovation.
Prior attendee stats: This exclusive community of 7,284 technical professionals comprises 45% machine learning specialists, 40% agentic systems builders, and 30% infrastructure engineers. Distinguished by a 30% founder-to-member ratio and researchers from Google DeepMind and Meta, members actively pioneer real-world autonomous agents, custom Model Context Protocol servers, and hardware-accelerated AI.
