OpenAI Slashes GPT-5.6 Sol API Prices for Three Months
In a strategic move to boost its market presence and respond to increasing competition, OpenAI has slashed the prices for its GPT-5.6 Sol API by more than 20% for a three-month period. The new pricing now stands at $4 per million input tokens and $20 per million output tokens, a significant decrease from prior rates. This cut follows recent reductions of 20% on its mid-tier GPT-5.6 Terra model and an 80% decrease for the affordable GPT-5.6 Luna model, underlining OpenAI's aggressive pricing strategy aimed at developers. The price adjustments come amidst intense competition from companies such as Anthropic and other emerging AI firms in China, with OpenAI now offering lower token rates compared to Anthropic's Claude Fable 5 and Claude Opus 5 models. While the price of the API for general use decreases, subscription costs for services like ChatGPT Plus, Pro, and Business will remain stable.
