OpenAI launched GPT‑6 Sol and Luna, and the API costs half
NEWS · OPENAIOn September 22, OpenAI released Sol and Luna: faster, cheaper models that bring almost all the power of GPT‑6 Astra, its strongest model. In the API they cost half of what the previous version did.
They are already in ChatGPT and Codex on paid plans. On the free plan, you can try Luna in the desktop app.
For your business, in plain terms: what was expensive yesterday costs half today.
