How should images be submitted when GPT-4o analyzes them?
When using Chat Completions, include a text question and an image_url image block in the content array of the user message, and place the image address in image_url.url. detail can be auto, low, or high. It is recommended to also specify whether you want recognition, comparison, or explanation, rather than submitting only an image without a task objective.
Can GPT-4o directly return generated images?
The gpt-4o on this page is used to understand text and images and generate text responses; it is not an image-generation entry point. If you need text-to-image generation, style changes based on reference images, or combined assets, choose gpt-4o-image or a dedicated image model. Understanding images and creating images are different delivery workflows, so first clarify whether the final output should be text or an image.
How should I choose between GPT-4o and gpt-4o-mini?
For combined image-and-text understanding, content explanation, and multilingual expression, prioritize evaluating GPT-4o; for simple and repetitive text tasks, try gpt-4o-mini first. It is recommended to compare key information retention, formatting stability, and number of revisions using the same set of real samples, then decide whether GPT-4o is needed rather than judging performance based only on the model name.
How can I make GPT-4o continue the previous discussion?
When using Chat Completions, place relevant history in messages; when using Responses, organize input and related conversation content according to the documentation. Provide the latest materials, revision goals, and key constraints each round; for longer tasks, retain periodic summaries and a final version that can be checked independently.
Does GPT-4o include web access and code execution?
Tool workflows should be organized according to the tool definitions and result formats of the selected public interface. The model is responsible for planning, explaining results, and generating call suggestions; querying, running code, and writing are completed by the execution environment provided by the application. Actual completion status should come from tool returns and verification records, and cannot be determined solely from the model's description.
