OpenAI's new GPT-6.1 Terra scores 57.6% on OpenAI's Agents' Last Exam at medium effort. So does GPT-6 Astra. Terra costs $0.29 a task. Astra costs $4.82. That is 16.6x apart for the same score. The catch: on Terminal-Bench 4.0 at max effort, Terra gets 50.3% and Astra gets 58.2%. OpenAI's own page says GPT-6.1 Sol and GPT-6 Astra "remain the better choice" for the most complex coding tasks.
