GPT-5 mini

OpenAI's cheap fast tier — strong-enough quality for high-volume work

GPT-5 mini is OpenAI's lightweight tier — cheap, fast, and strong enough for the bulk of production traffic that doesn't need frontier reasoning. The natural pick when you need OpenAI compatibility but don't want to pay frontier prices for routine work. Pairs well with GPT-5 in router patterns (mini-first, escalate on complexity).
