It’s been a few weeks since OpenAI introduced GPT-6 Astra and took the internet by storm. Now, the company is introducing new, more cost-effective GPT-6 models for users who need a powerful AI model at a considerably lower price.

OpenAI announced the launch of GPT-6 Sol and GPT-6 Luna today, and the company is focused on showing how affordable and capable both models are. API pricing for both GPT-6 Sol and Luna has been reduced significantly compared to GPT-5.6 Sol and Luna. Both are now 50% cheaper to use.
