DeepSeek's call volume is three times that of OpenAI, and after discounts proved ineffective, OpenAI opted for a free model.

On August 6 local time, OpenAI announced that the default model for free users has been upgraded to GPT-5.6 Luna, and unlimited text chatting has been made available, benefiting approximately one billion ChatGPT users worldwide. Yesterday, DeepSeek released an announcement stating that it plans to significantly raise the pricing of its API services in the near future. The contrasting actions of raising and lowering prices reflect the rise of domestic open-source models, which is forcing a reconstruction of the global AI pricing system.
