The facts

  1. The release targets computer use, visual reasoning, coding and writing. ChatGPT access includes Plus, Pro, Enterprise and Edu plans. [1][2]

  2. The API model is named gpt-6.1-terra. Standard prices per million tokens are US$1 for input, $0.05 for cached input and $5 for output. [1]

  3. OpenAI positions Terra for faster, lower-cost work and says GPT-6.1 Sol and GPT-6 Astra remain preferable for its most complex coding tasks. [1]

  4. Published speed and benchmark comparisons are OpenAI's claims; they do not establish equivalent gains on every real-world task. [1][2]

Still unconfirmed

  • Independent performance across different workloads remains to be established.
