OpenAI brings GPT-6 to lower-cost everyday workflows
OpenAI released GPT-6 Sol and Luna for the API, Codex and ChatGPT Work, positioning them as faster, more affordable alternatives to Astra. The launch combines lower token prices with caching improvements and vendor-reported gains in coding, factuality and computer use. Availability is not the same across every ChatGPT surface, and benchmark results are not guarantees for a team's own tasks.
