LLMday is a global conference series focused on large language models, AI agents, and AI systems. Its in-person events bring together engineers, researchers, designers, founders, and other technology practitioners to share ideas, explore practical applications, and connect with peers. The conferences are aimed at communities working in AI and adjacent fields, including SRE, DevOps, and platform engineering.

LLMday organizes events across Europe and the United States, with a presence spanning more than eight countries. Its calendar includes conferences in cities such as San Francisco, Austin, New York, Tel Aviv, Hamburg, London, and Montevideo, as well as events that combine AI with data or platform engineering. The program includes talks and practical demonstrations, while opportunities to participate include submitting proposals to speak, sponsoring, or partnering with an event.

A network of ambassadors helps extend the community into cities around the world. Attendees and ambassadors describe LLMday as welcoming and community-driven, with conversations continuing beyond the formal sessions.
