GPT Image 3 Agent is a free online conversational AI agent that combines image generation and photo editing in one workspace. It keeps prompts, reference photos, and chosen results connected, allowing users to generate new visuals, edit photos with references, and refine any result through follow-up instructions. The workspace offers three image models: GPT Image 2 by OpenAI, Nano Banana Pro (Gemini 3 Pro Image) by Google, and Nano Banana 2 (Gemini 3.1 Flash Image) by Google. Users can start from a text prompt or an uploaded photo, and the agent maintains context across edits, so each follow-up starts from the right visual state.
What is GPT Image 3?
GPT Image 3 is a conversational AI agent for photo editing and visual creation. It takes text instructions and optional reference photos as input, and produces edited or newly generated images. The agent runs in a web browser at gptimage3.dev and is an independent service that uses models from OpenAI and Google, as stated on the page.
Key Features
- Conversational workspace — Keep prompts, reference photos, selected model, and generated results connected in one conversation, so follow-ups don't require rebuilding the prompt.
- AI photo editor — Edit photos with references, change one detail at a time, compare edits, and continue from any result without repeating the full brief.
- Reference-based creation — Use an uploaded image as a reference to create new visuals while preserving structure, materials, colors, and key design details.
- Multiple image models — Choose from GPT Image 2 (OpenAI), Nano Banana Pro (Gemini 3 Pro Image), and Nano Banana 2 (Gemini 3.1 Flash Image) by Google.
- Free online access — No cost mentioned for using the agent; the page emphasizes free online access.

How does GPT Image 3 work?
The agent works conversationally: you describe a task in plain language, optionally upload a reference photo, and the agent generates or edits an image. Each follow-up instruction is applied to the previously selected result, so you can refine details without restarting. The workspace keeps the prompt, reference photos, chosen model, and generated results connected throughout the session.
