LLMday + Prompt Engineering Conference - London 2026 Q4

Good morning London, LLMday and the Prompt Engineering Conference are joining forces! This year, we’re bringing both communities together under one roof for a joint London event dedicated to LLMs, AI engineering and prompt engineering. The conference will run across 3 parallel tracks: 2 LLMday tracks and 1 Prompt Engineering Conference track, with tech sessions, hands-on workshops and plenty of opportunities to meet and connect with fellow AI engineers and enthusiasts. Whether you’re building with LLMs, working on AI systems, experimenting with agents, getting serious about prompt engineering, or just starting to explore the space, you’ll find plenty to dig into. We’re aiming for 30+ speaking sessions and 200+ attendees, with the schedule filling up over the coming months. LLMday is organized by Miko and Mark, the team behind LLMday, SREday and Conf42.The Prompt Engineering Conference is hosted by Maxim Salnikov. For the London edition, both teams are working together to create one bigger event. 3 tracks. 2 conferences. 1 ticket.
