OpenAIGPT-6.1 Terra
An OpenAI model for interpreting images, working with application screens and producing clear written responses.
Plain-English overview
What GPT-6.1 Terra actually is
GPT-6.1 Terra accepts text and images and returns text. Use it for visual document analysis, screen-based workflows and writing tasks.
Reasoning ranges from none to max, with medium as the default. Tool calling requires the Responses API.
Good fit for
- Visual document analysis
- Computer-use workflows
- Writing and editing

Pricing & comparisons
Estimate your cost
Set your usage. Your estimate updates as you type.
Example: 6,000 input tokens for 10 pages, plus a 500-token summary. Page lengths vary; adjust the numbers below.
One run sends your input to the model once and receives an answer. Tokens are pieces of text: input is what you send, output is the answer you receive.

The route matters.
OpenAI says API inputs and outputs are not used for model training by default. Default abuse-monitoring logs may be retained for up to 30 days; qualifying organizations can request other controls.
This is a concise reading of the cited provider material, not legal advice. A third-party gateway can have different storage, routing, training, and residency terms from the model maker's direct API.

Price comparison
One price per model, using the same input/output mix. We weight each API rate by its share of one million total tokens and use the lowest matching reviewed route. This is a comparison rate, not a cost per task or a quality score. Tokenizers, caching, reasoning and long context can change your actual bill.
