Best for
- Pipelines tuned and evaluated against GPT-5.4.
- Balanced coding and content workloads.
- Teams migrating gradually to GPT-5.6 Terra.
Good to know
- Reasoning efforts none through xhigh; the max level is exclusive to the GPT-5.6 line.
- gpt-5.6-terra is now the cheaper balanced tier ($2/$12 vs $2.50/$15) — new projects should usually start there.
- Requests above 272K input tokens bill at OpenAI long-context rates: 2× input and 1.5× output on the whole request.
