OpenAI to cut GPT-5.6 Sol API prices by over 20%
OpenAI also slashed prices for its smaller Terra and Luna models last month.
OpenAI has reduced the prices of its GPT-5.6 Sol model for developers by over 20% for the next three months. The new prices are $4 per 1 million input tokens and $20 per 1 million output tokens. These changes apply to OpenAI's application programming interface and eligible plans for credits on its products ChatGPT Work and Codex.
The price cuts come as OpenAI faces growing competition from Anthropic and Chinese AI models. According to Investing.com, OpenAI previously priced GPT-5.6 Sol at $5 per 1 million input tokens and $30 per 1 million output tokens. The company has also recently reduced prices for its smaller models, including a 20% cut for the GPT-5.6 Terra model and an 80% cut for the Luna model.
Anthropic's pricing for its Claude models is listed as $10 per 1 million input tokens and $50 per 1 million output tokens for the Claude Fable 5 model, and $5 per 1 million input tokens and $25 per 1 million output tokens for the Claude Opus 5 model, according to Investing.com. Pricing for OpenAI's Pro, Plus, and Business subscriptions remains unchanged.
