DeepSeek calls three times the number of OpenAI, and OpenAI chooses to be free if the discount is invalid

On 7 August, according to the local time, on 6 August, OpenAi announced that the free user default model would be upgraded to GPT-5.6 Luna and open to unlimited text chats, which would directly benefit about a billion ChatGPT users worldwide. Yesterday, DeepSeek announced a plan to increase the price of API services as a whole in the near future, with a significant increase expected. Disparities reflect the emergence of an open source model of domestic production, which is pushing the global AI pricing system upside down。
