  "account": "OpenAI has upgraded its ChatGPT and Codex with a new GPT-6.1 Terra model, boasting faster performance and lower computer usage costs. This is the fourth model class introduced by OpenAI, following Luna, Sol, and Astra. GPT-6.1 Terra offers improved visual reasoning, computer usage, and writing while being more cost-effective. It is priced at 50% lower than the previous GPT-5.6 Terra, making it a more affordable option for automating computer-related tasks.\n\nOpenAI reports that GPT-6.1 Terra demonstrates significant improvements in error rates when handling prompts with low reasoning effort, dropping from 53.6% to 16.7%. The error rate at maximum effort has also decreased from 4.3% to nearly matching the rates of GPT-6 Astra and GPT-6.1 Sol. These advancements make GPT-6.1 Terra a step forward in intelligence and accuracy compared to its predecessor.\n\nThe new medium-sized model is currently available through ChatGPT Work, Codex, and API. For more information about the GPT-6.1 Terra model, visit the official OpenAI website.",
