OpenAI Launches GPT-6 Sol and Luna, Cutting API Prices by 50%
OpenAI has added two new models, GPT-6 Sol and Luna, to its GPT-6 lineup, trained with methods similar to those behind GPT-6 Astra and priced at roughly half the API cost. The company says the smaller models carry over Astra's gains in coding, computer use, factuality and alignment, while Astra remains its strongest offering.
