Text AI · Subscription vs API
ChatGPT Plus vs APIMost solo users overpay on the flat plan.
Verdict
ChatGPT Plus is $20.00/mo regardless of usage. The API charges per token — roughly $0.4 per million input tokens for GPT-4.1 mini. The break-even point is roughly 50M tokens/month at GPT-4.1 mini pricing, or 130M tokens/month if you use GPT-4.1. Most solo users send under 2M tokens per month — meaning the API costs under $1.
