OpenAI cuts GPT-5.6 Sol API prices by over 20%
Technology
OpenAI cut prices for its frontier GPT-5.6 Sol model on the API by more than 20% for the next three months, rolling out across eligible plans for credits on ChatGPT Work and Codex.
Now, it's $4 per million input tokens and $20 per million output tokens (down from $5 and $30).
If you're on Pro, Plus, or Business subscriptions, though, your prices stay the same.
OpenAI discount saves developers money
This price cut puts OpenAI well ahead of rivals like Anthropic (whose Claude Fable 5 model costs much more) and follows recent discounts on other OpenAI models too.
It's a clear move to help developers save money and keep OpenAI competitive as AI tools get more crowded.
