LLMday NYC 2026 Q4: LLMs, AI & Machine Learning

LLMday brings engineers, researchers and product teams to New York for a full day of practical insight into building, deploying and operating AI systems. Taking place on Thursday 29 October 2026, from 9:00am to 6:00pm EDT, this in-person conference focuses on Large Language Models (LLMs), artificial intelligence and machine learning. It offers a space for people working directly with AI products and infrastructure to compare real-world experience rather than discussing the technology only in theory. ## What to expect The programme is centred on the practical challenges encountered across the AI system lifecycle. Attendees can expect content relevant to: - Building products and services powered by LLMs - Deploying AI and machine-learning systems - Operating AI systems in real-world environments - AI/ML engineering and cloud architecture - Lessons shared across engineering, research and product disciplines The event page does not yet list individual sessions or speakers, but the latest programme information is available on the official Speakers & Topics page. ## Who should attend? LLMday is designed for engineers, researchers and product teams working with,or actively exploring,LLMs, AI and machine learning. Its cross-functional focus should be particularly useful for attendees who want to understand how technical research, product decisions and operational requirements come together when moving an AI system into production. The one-day, in-person conference format provides a concentrated opportunity to learn from real implementation experience and meet others facing similar questions around AI development, deployment and operation. Meetup attendees can also access the event chat before the conference to connect with other participants and take part in the conversation. ## Venue and registration Hosted by Mark P. and the In-Person Tech Events NYC 2026 group, the conference will be held at the Microsoft Experience Center, 677 Fifth Avenue, New York, NY 10022.
