Aug 21 (Reuters) - OpenAI said on Friday it is cutting the prices of its frontier GPT-5.6 Sol model for developers by more than 20% for the next three months, as the ChatGPT maker faces growing competition from Anthropic and Chinese AI models.
Here are more details:
• The price cuts are effective on OpenAI's application programming interface, or API, and are rolling out across eligible plans for credits on its agentic AI product ChatGPT Work and its coding tool Codex, OpenAI said.
• Pricing for Pro, Plus and Business subscriptions remains unchanged, the company said.
• GPT-5.6 Sol is now priced at $4 per 1 million input tokens and $20 per 1 million output tokens for standard short-context use, according to OpenAI's pricing table. That compares with previous prices of $5 and $30, respectively.
• OpenAI late last month slashed prices of its smaller models. It cut prices for the mid-tier GPT-5.6 Terra model by 20% and for the lower-cost Luna model by 80%.
• Anthropic lists its frontier Claude Fable 5 model at $10 per 1 million input tokens and $50 per 1 million output tokens, while its Claude Opus 5 model is listed at $5 per 1 million input tokens and $25 per 1 million output tokens.
