OpenAI has announced a reduction in the cost of two models of the GPT-5 series.6. The Luna model has fallen in price by eighty percent. Now it costs $0.20 per million input tokens. The output tokens will cost $1.20 per million. Previously, these figures were $1 and $6, respectively. The Terra model received a more modest price reduction. The cost has decreased by twenty percent. Entry tokens are now worth $2 per million. The output tokens are estimated at $12 per million. The price of the flagship Sol model remained unchanged. OpenAI has also introduced a Fast mode for Sol. This mode increases the processing speed by 2.5 times. The cost of the accelerated version is twice as high as the standard one. The company claims that the intelligence of the model does not decrease.

Reduced prices affect the consumption of the quota of paid subscriptions. Models now consume fewer credits in Codex and ChatGPT Work. Subscription prices and quota volumes remain the same. OpenAI explains the price reduction by increasing the efficiency of the systems. The GPT-5.6 Sol model independently optimized production GPU cores. This helped to reduce maintenance costs by twenty percent. Improved speculative decoding has increased the efficiency of token generation. This figure has increased by more than fifteen percent. CFO Sarah Friar described this relationship. Developed intelligence stimulates the widespread distribution of products. Widespread distribution supports additional investments. More investment improves the intelligence and overall efficiency of the system.

The next day, Friar reported a billion active users. More than two million companies use OpenAI models. The company did not specify the audience measurement period. Previously, ChatGPT had over 900 million weekly users. User engagement grows over time. Six months later, people are sending 50% more messages. They use ChatGPT for twice as many tasks. In 2025, OpenAI's revenue was $13.07 billion. At the same time, the company lost $21 billion. Only about 50 million users paid for a subscription. Fixed-rate subscriptions can become unprofitable. This happens with heavy use of services. Lower prices can push for wider distribution. Analysts warn of possible pressure on margins. The company continues to invest in computing infrastructure.
