The 1st workshop on Inter-networking challenges for AI (INet4AI), collocated with ACM CoNEXt'25, was held on the 1st of December 2025 in Hong-Kong. The workshop was inspired by ongoing discussion in the IRTF on research challenges for (inter-)networking technologies for AI workloads.

This full day workshop explored some of the networking challenges of large-scale distributed AI workloads in environments, characterized by node and network heterogeneity, as well as dynamically changing resource availability and utilization. During this inaugural edition, researchers from both academia (HKUST, ETH Zurich, Politecnico di Milano, University of Napoli, Tsinghua University, TU Munich) and industry (Huawei, AMD, Microsoft, and others) discussed possible solutions to address the challenges raised by Internet-scale distributed AI systems with four workshop paper presentations and three invited talks. In this report, we will first give a summary of the workshop papers and invited talks. Then we will draw some general remarks regarding the ongoing efforts done in our community to address INet4AI challenges.
