Conf42 Prompt Engineering 2026

About

Conf42 Prompt Engineering is a single-day online conference examining how developers design, test and maintain the instructions that drive large language model systems. It forms part of the Conf42 series of free, fully remote technical conferences. Prompt engineering has moved from an informal craft to a discipline with real engineering weight — versioning, evaluation, regression testing and cost control all now apply. The conference addresses that shift, covering systematic prompt design, evaluation harnesses and benchmarks, retrieval integration, structured output and tool calling, and the management of prompt behaviour as underlying models change beneath production systems. Speakers are drawn from teams operating language model applications rather than from research settings, keeping the material grounded in deployment reality. The remote format removes travel cost and opens attendance across time zones, with recordings available following the live event. For software engineers, machine learning practitioners and product teams building on large language models, this online AI conference provides a focused survey of prompt engineering practice as it consolidates into standard tooling and process.
