OpenAI expands GPT-6 lineup with cheaper Sol and Luna models

OpenAI on Tuesday expanded its GPT-6 AI lineup with two models priced at half the promotional rates of their predecessors, while offering some of the capabilities of its flagship Astra.

The launch of low-cost GPT-6 Sol and GPT-6 Luna follows the rollout of GPT-6 Astra, a faster model for handling more tasks than previous iterations, earlier this month.

This comes as AI companies focus on reducing the cost of running increasingly capable models.
