Short answer: start on Free. Upgrade only if a published limit interrupts real work more than once a week. Exact localized Plus prices were not consistently exposed on OpenAI’s official pricing page during the last check, so verify openai.com/chatgpt/pricing before you pay.
What is official
OpenAI lists ChatGPT Free, Go, Plus, Pro, Business, and Enterprise. Free is $0. Paid self-service plans are billed per user per month. Enterprise is sales-assisted. Our last official-source check (2026-08-25) did not treat unofficial third-party dollar amounts as list prices.
What paying is for
- Higher usage limits when Free interrupts a weekly workflow
- Priority access to newer models and advanced features
- Business or Enterprise terms when client files cannot sit on a consumer chat plan
A one-week test
Use Free on your three real tasks. Write down every limit hit. If it happens five or more times, open the official pricing page and compare that cost to an hour of your time. See also Is ChatGPT worth it? and the ChatGPT review.
