The article examines the application of large language models for network incident diagnosis within AIOps. Traditional network management methods are shown to become ineffective under exponentially growing telemetry data volumes. Key LLM applications are analyzed: automated log analysis, localization of root causes of failures, natural language network interaction, and multi-agent systems. Technology limitations are considered: LLM hallucinations, excessive agency, vulnerability to attacks, privacy concerns, and computational complexity. It is concluded that LLMs open new opportunities for intelligent automation of network diagnostics.
