Testing GPT-5.2 Performance Specs in Copilot

This article shares tests conducted on the Linux.do forum, evaluating the juice value of the GPT-5.2 model in Codex and Copilot. Test results show that Copilot’s spec is medium and cannot access the gpt-5.2 xhigh version. Users explored the model’s performance limitations by calculating the juice number divided by 2 multiplied by 10 divided by 5. This finding provides a reference for understanding the practical applications and performance boundaries of AI models, revealing the differences in specifications among AI services.
