About gpt-5.6-terra

GPT-5.6 Terra balances capability and cost within the GPT-5.6 family. Its official positioning roughly corresponds to the mini tier of earlier GPT families. Text and image inputs produce text, making it a candidate for everyday code assistance, structured synthesis and bounded reasoning.

A model tier does not determine final cost or completion rate for every task. Check endpoints and the selected route before changing reasoning effort, using tools or requesting structured output. Choose with actual usage and this site’s group prices.

Use cases and prompting

State inputs, outputs and edge cases for everyday code tasks, with executable examples where possible.
Define fields and types for structured synthesis. Validate the format in your application instead of accepting readable text as valid data.
Compare reasoning levels incrementally on the same samples, recording rework and actual usage before scaling up.
Compare harder work with GPT-5.6 Sol and smaller high-volume steps with GPT-5.6 Luna. See the documentation for integration.
