About GPT-5.6 Terra
OpenAI positions GPT-5.6 Terra between Sol and Luna, balancing intelligence and cost. It corresponds roughly to the mini tier in earlier GPT families. Compare it with Sol on moderately complex tasks where a reliable structure matters and the strongest model may be unnecessary.
Work with GPT-5.6 Terra
Bring your context
Start with your own brief and source material so the response addresses the actual task.
Set a clear outcome
Ask for a memo, an explanation or a structured draft, with the constraints that matter.
Compare responses
Try the same task with another available model to examine differences in reasoning and writing.
Review the evidence
Check facts, source references and assumptions before sharing the result.
A task to try
Start with this example, then adapt the brief to your own material.
- Convert a product brief into a structured requirements list with acceptance criteria and follow-up questions.
- Specify the audience, intended format and any information the answer must include.
- Ask the model to separate source facts from assumptions and unanswered questions.
- Review the response against your source material and request targeted revisions.
