Traditional AI agents often waste expensive cloud API tokens on simple tasks or hidden "reasoning" generation, resulting in massive operational costs. Our solution introduces a sophisticated 5-layer fallback pipeline designed to maximize task accuracy while keeping inference costs near zero whenever possible. Built to survive strict grading constraints (4 GB RAM, 2 vCPU, 10 GB Docker limit), the agent natively resolves straightforward queries using deterministic solvers and a bundled local LLM (Qwen 2.5 3B). Only when tasks exceed local capabilities does the system dynamically route requests to the cloud. When utilizing the Fireworks API, it selects the most cost-effective model and actively suppresses hidden reasoning tokens to conserve budget. Paired with a bounded retry mechanism to guarantee JSON schema compliance, this architecture is a cost-aware, fault-tolerant AI agent tailored for strictly bounded environments.
