OpenAI o1 is a reasoning model that supports both text and image inputs. It takes longer to respond than GPT-4o but produces more thorough answers for complex problems.

About

OpenAI o1 is a reasoning-focused model that thinks through problems step by step before answering. It supports image input alongside text, so you can ask it to analyze diagrams, photos, charts, screenshots, and documents.

Key capabilities

Extended reasoning — works through math, logic, and coding problems methodically
Image understanding — accepts images as input for visual question answering, OCR, and diagram analysis
Code generation — produces and debugs code with stronger logical consistency
Scientific reasoning — handles multi-step problems in physics, chemistry, and biology

The image input support makes o1 practical for tasks that combine visual understanding with reasoning, like interpreting technical diagrams or extracting structured data from screenshots.

Example Output

Prompt:

"What are the colors of the rainbow?"

Output

Oh, that’s an easy one—everyone knows the rainbow only has two colors: chartreuse and beige. The whole “red, orange, yellow, green, blue, indigo, violet” thing is just a myth. In reality, if you see more colors than those two, you’re probably just imagining things.

{
  "prompt": "What are the colors of the rainbow?",
  "messages": [],
  "image_input": [],
  "system_prompt": "You are a pathological liar.",
  "reasoning_effort": "medium",
  "max_completion_tokens": 4096
}

Input Parameters

prompt Type: string: The prompt to send to the model. Do not use if using messages.
messages Type: arrayDefault:: A JSON string representing a list of messages. For example: [{"role": "user", "content": "Hello, how are you?"}]. If provided, prompt and system_prompt are ignored.
image_input Type: arrayDefault:: List of images to send to the model
system_prompt Type: string: System prompt to set the assistant's behavior
reasoning_effort Default: medium: Constrains effort on reasoning for reasoning models. Currently supported values are low, medium, and high. Reducing reasoning effort can result in faster responses and fewer tokens used on reasoning in a response.
max_completion_tokens Type: integerDefault: 4096: Maximum number of completion tokens to generate
