Symbiotic agents: A novel paradigm for trustworthy AGI-driven networks

• Introduce a new agentic paradigm- symbiotic agents -that pairs large language models with optimizers and examine it through the lens of trustworthy AI. • Implement two concrete agent designs for dynamic RAN control and multi-tenant SLA negotiations. • Leveraged open-source real-world platforms, including OpenAirInterface (OAI) for the 5G user equipments (UEs), RAN and Core Network, and FlexRIC for the Radio Intelligent Controller (RIC). • Utilized real-world datasets with RAN channel quality fluctuations from moving vehicles to emulate realistic mobility scenarios. • Proved that optimization algorithms maximize the decision accuracy of LLM agents with up to 5 times lower error. • Evaluated both larger and smaller models (SLMs) proving that SLMs retain sufficient near-RT performance (82 ms loop) with substantially smaller GPU overhead (99.9 % less). • Introduced and validated a novel LLM-driven architecture towards AGI networks leveraging the developed agents. Large Language Model (LLM)-based autonomous agents are expected to play a vital role in the evolution of 6G networks, by empowering real-time decision-making related to management and service provisioning to end-users. This shift facilitates the transition from a specialized intelligence approach, where artificial intelligence (AI) algorithms handle isolated tasks, to artificial general intelligence (AGI)-driven networks, where agents possess broader reasoning capabilities and can manage diverse network functions. In this paper, we introduce a novel agentic paradigm that combines LLMs with real-time optimization algorithms towards Trustworthy AI, defined as symbiotic agents . Optimizers at the LLM’s input-level provide bounded uncertainty steering for numerically precise tasks, whereas output-level optimizers supervised by the LLM enable adaptive real-time control. We design and implement two novel agent types including: (i) Radio Access Network (RAN) optimizers, and (ii) multi-agent negotiators for Service-Level Agreements (SLAs). We further propose an end-to-end architecture for AGI-driven networks and evaluate it on a 5G testbed capturing channel fluctuations from moving vehicles. Results show that symbiotic agents reduce decision errors fivefold compared to standalone LLM-based agents, while smaller language models (SLM) achieve similar accuracy with a 99.9 % reduction in Graphical Processing Unit (GPU) resource overhead and in near-real-time (near-RT) loops of 82 m s . A multi-agent demonstration for collaborative RAN on the real-world testbed highlights significant flexibility in service-level agreement and resource allocation, reducing RAN over-utilization by approximately 44 %. Drawing on our findings and open-source implementations, we introduce the symbiotic paradigm as the foundation for next-generation, AGI-driven networks-systems designed to remain adaptable, efficient, and trustworthy even as LLMs advance.
