GreptimeDB introduces a semantic layer that preserves OTLP metadata (instrument kind, unit, temporality) which is normally discarded at ingestion, enabling AIOps tools and LLM agents to understand system topology without guessing from column names.
Nankai University and Lenovo collaborated to propose Graph of States (GoS), a neuro-symbolic framework for general abductive reasoning, which uses explicit belief states and state machines to control multi-agent collaboration, achieving significant improvements in medical diagnosis and system fault diagnosis tasks. This work was accepted at ICML 2026.
