OpenAI、無料ユーザーをGPT-5.6 Solからより弱いLunaモデルへ変更
OpenAIは有料ユーザー向けにGPT-5.6 Solを改良し、無料ユーザーはより弱いGPT-5.6 Lunaモデルに制限した。これにより、OpenAIの最も強力な推論能力への無料アクセスが制限される。
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.
