[cost\_intel] Paying reasoning costs for simple pattern-matching queries

Deploy a tiny classifier \(Llama 3.1 8B or GPT-4o-mini\) to route 80% of simple queries \(retrieval, extraction\) to cheap instruct models \($0.001/1k tok\) and 20% complex reasoning \(math, security\) to o1/o3. This achieves 95% of full-reasoning accuracy at 15-20% of the cost.

Journey Context:
Query complexity is predictable. Simple queries are pattern matching; hard queries require planning. Using o1 for everything is 25x overpriced. The classifier costs $0.0001/query, negligible. The 'one model for all' anti-pattern destroys ROI. FrugalGPT proves cascading yields better accuracy-cost frontier than any single model.
