OpenAI has released GPT-6.1, offering two new models: Terra and Sol. The primary question for users is when to choose Terra over Sol, as benchmark results appear mixed and cost-effectiveness depends heavily on the specific task. Terra is positioned for tasks like specified computer use, visual checks, and writing from existing material, especially when cost and speed are critical and corrections are minimal. Sol, on the other hand, is recommended for more complex coding tasks where its performance may outweigh its slightly higher cost. AI
IMPACT Provides guidance on selecting between two new OpenAI models, Terra and Sol, based on task type and cost-effectiveness.
