Ignore the model names. You can't pick "GPT Image 1.5" or ask for "DALL·E" — DALL·E was switched off on 12 May 2026 and GPT Image 1.5 is being retired from OpenAI's developer service on 1 December 2026. Any guide telling you to select one is out of date.
Go to chatgpt.com and sign up free with an email, Google or Apple account. Image generation is included on the free plan, so you can make pictures on day one without a card. ChatGPT isn't offered in every country, and OpenAI warns that getting around that can cost you the account.
You probably won't need to pay to try this, but you'll notice the ceiling quickly: OpenAI describes free image generation as limited and slower, and the cap on images is counted separately from the cap on chat messages — you can run out of pictures while text still works. The paid options are Plus and a cheaper Go plan beneath it, with prices varying by country.
One capability is genuinely behind the paywall rather than just rationed: OpenAI's help pages state that "Images with thinking" — where the model works through a complicated instruction before drawing — is available on Plus, Pro and Business. On the free plan, a request with several fussy requirements in it will come back partly wrong, and rephrasing won't fix it.
