An article summarized by Reuters:

OpenAI has significantly reduced prices for two of its AI models, cutting the cost of its GPT-5.6 Luna model by 80% and its GPT-5.6 Terra model by 20%, while keeping pricing for its flagship Sol model unchanged. The move reflects growing pressure from businesses looking for more affordable AI tools and increasing competition from lower-cost Chinese AI companies.

The price cuts also increase pressure on rivals like Anthropic, whose Claude models remain more expensive despite their popularity with enterprise customers. OpenAI said improvements in GPT-5.6's efficiency allowed it to lower prices, making its smaller and mid-tier models capable of handling tasks that previously required more powerful, and more expensive, AI systems. Businesses will now pay substantially less per million tokens for both input and output when using Luna and Terra.

The broader AI industry is shifting toward usage-based pricing, where companies pay based on how much they use AI rather than a flat subscription fee. While the cost per token has generally fallen over the past year, businesses are facing less predictable bills as AI tasks become more complex and consume more tokens. Analysts say lower prices could drive wider adoption of AI, but they may also pressure the finances of companies like OpenAI and Anthropic ahead of potential public offerings.
