Cost Reduction per Token with SLMs
Why Small Language Models (SLMs) Are Critical for Autonomous Agents
Autonomous agents require high-frequency, iterative loops. SLMs offer sub-second inference times, crucial for maintaining agent 'flow' and preventing timeouts. They ensure data sovereignty by running locally, vital for critical infrastructure. Economically, SLMs cost 10-30x less per token, making pervasive AI agents viable by leveraging a fixed-cost model of electricity and hardware amortization.
Mixture of Experts (MoE) Architecture
MoE architecture, like Minimind-MoE, decouples model capacity from inference cost. A gating network routes tokens to specific experts, meaning only a fraction of parameters activate per inference step. This enables high reasoning power on resource-constrained edge hardware, making it ideal for low-latency execution and edge deployment without bottlenecking transactional checks.

Commercial Tools & Headless Autonomy
Benchmarking against the Gemini CLI sandbox revealed it requires interactive authentication ("Sign in"), rendering it unusable for headless, autonomous agent workflows. This highlights a critical divergence: commercial tools prioritize human-in-the-loop safety over machine-in-the-loop autonomy, where our transactional approach excels.
Proxmox/EVPN Testbed
Experiments were conducted on a custom Data Center Testbed simulating a production cloud environment. It utilized Proxmox VE 9.0 for LXC containers and VM with GPU passthrough, and Ethernet VPN (EVPN) with VXLAN encapsulation for network isolation, ensuring agents are strictly isolated in a specific Virtual Network Identifier. Storage leveraged ZFS-backed volumes for potential future snapshot performance.
AIOps
Transactional Safety for Network Orchestration
Extending to AIOps for Cellular Networks
The principles of atomic execution and state validation are directly transferable to AIOps for 5G/6G Core networks. Configuration changes in these networks are analogous to 'tool calls', where an invalid change can take down a network slice. Adapting this transactional sandbox into an Intent-to-Action controller can ensure safe and reliable network orchestration.
Federated Learning with Small Language Models
The compact size of SLMs makes them suitable for edge devices (routers, base stations). Future work can involve agents learning from local failures, sharing gradient updates locally instead of sending all sensitive data to a central cloud. This allows a fleet of network repair agents to collectively improve their 'repair policies' without exposing sensitive network topology data.
Turning Safety Signals into Learning Signals
The sandbox's refusal of destructive commands acts as a negative reward signal for the agent. Implementing 'Sandbox-Aware Prompting'—explicitly informing the agent it's in a transactional sandbox—can help it interpret 'Policy Violation' errors as a boundary constraint requiring a logical plan revision, improving reasoning over time.
