The new model comes with an API price 50% below GPT-5.6 Terra. On Terminal-Bench 4.0, it scores 50.3% at maximum effort. OpenAI also reports that, at low effort, the error rate fell from 53.6% to 16.7%.
Why it matters A cheaper frontier model puts pressure on prices across the whole industry and changes the math for anyone using the API at scale.
