OpenAI 将免费用户从 GPT-5.6 Sol 迁移至较弱的 Luna 模型
openai 改进了付费用户的 gpt-5.6 sol，并将免费用户限制在较弱的 gpt-5.6 luna 模型。这限制了免费用户使用 openai 最强大的推理能力。
openai enhanced gpt-5.6 sol with direct answers and a 68% reduction in factual errors compared to gpt-5.5 instant. paid subscribers now control response depth via a slider to toggle between quick answers and deep reasoning. conversely, free users will be downgraded to gpt-5.6 luna, losing access to the more powerful sol model despite receiving unlimited text chats. this move prioritizes conversion, forcing users who need reliable reasoning to pay.
