Please welcome GPT-6 Sol and GPT-6 Luna to the GPT-6 universe.
GPT-6 Sol and Luna build on the advances behind GPT-6 Astra, bringing much of its strengths into faster and more affordable models to support work at scale.
We’ve also made caching and inference more efficient, and we’re passing the savings directly to you: 50% lower API prices for Sol and Luna compared with GPT‑5.6 promotional pricing.
Finally the whole cc subscription will be useful. Not just the first 50% Fable part.
It's not just about the cheaper price, you can use the whole sub with it! So it's like 4x as much you can do now compared to Fable yesterday
