How to choose
Price is only the first filter
Use this table to eliminate models that do not fit your unit economics, then benchmark the remaining candidates on your own task for output quality, latency, rate limits and operational reliability.
GPT-5 Nano currently has the lowest tracked input-token price in this OpenAI set. That does not automatically make it the lowest-cost model for every workload because output ratios, caching, long-context rules and tool usage can change the result.
