OpenAI has introduced GPT-6 Sol and GPT-6 Luna to its GPT-6 range, which are faster and more affordable versions of the models trained using methods similar to those used with GPT-6 Astra, as OpenAI has stated. The company is cutting the API prices for Sol and Luna by 50% when compared to the promotional rates of GPT-5.6. GPT-6 Astra, which was launched this month, is still OpenAI's best model in all respects.
