GPT-5 Image
GPT-5 paired with OpenAI's image generator: chat, then create or edit images in the same conversation, with image input. Good for iterating on visuals in plain words. No tool calls, and expensive per message. GPT-5 Image Mini is the cheaper option; Nano Banana Pro is worth comparing.
GPT-5 Image is a legacy model. Its successor, Nano Banana 2.1, is faster or cheaper - and chats that used GPT-5 Image move to it automatically.
