GPT-4o mini is already one of the cheapest options in its tier. For budget-critical workloads, consider caching common requests to save more.
The three highest-leverage ways: (1) route requests to a cheaper model where possible, (2) cache identical requests so you don't pay twice for the same response, (3) set hard monthly budgets that block requests when exceeded. TrackCost automates all three at the gateway layer.
GPT-4o mini supports up to 128,000 tokens of context. For comparison with other models, use the TrackCost savings calculator.
