On the Same Day, DeepSeek Raises Prices and OpenAI Gives Away Free Chat

On August 6, 2026, two AI companies made pricing moves in opposite directions on the same day. Chinese AI lab DeepSeek announced that it plans to raise the price of its API service, with a large increase. Hours later, OpenAI said that GPT-5.6 Luna would become the default model for ChatGPT free users, and that free and Go tier users would no longer face a fixed message cap for normal text chats.

DeepSeek built its name by selling access to its models at very low prices. For years, this low-cost strategy helped it win many enterprise and developer customers around the world. Now the company says it must charge more to keep up with computing costs and to fund future model training. The exact new price has not been shared, but DeepSeek warns that the increase will be significant.

OpenAI is moving the other way. By putting GPT-5.6 Luna behind the free tier, the company is betting that more users, even free ones, will become the foundation of future revenue. A new Think button lets users ask the model to spend more time on hard questions, although this still uses Luna rather than the more powerful GPT-5.6 Sol paid tier. Image, file, and tool usage stay limited.

Together, the two moves show a clear split in AI business models. Chinese labs are moving from subsidized growth to serious monetization, while American labs are doubling down on freemium to lock in user acquisition. For developers and businesses, the message is simple: AI pricing is no longer a one-way race to the bottom, and the cost of building on top models is starting to rise.
