Details
- Sam Altman announced GPT-6 Sol and GPT-6 Luna as successors to the GPT-5.6 family.
- OpenAI says the models improve intelligence, alignment, work output, coding, computer use, and other capabilities.
- The models are priced at roughly half the previous generation’s per-token rates, with additional savings possible on a per-task basis.
- GPT-6 Sol is listed at $2 per million input tokens and $10 per million output tokens.
- GPT-6 Luna is listed at $0.10 per million input tokens and $0.50 per million output tokens.
- Sol and Luna are available through the OpenAI API, with access also rolling out in ChatGPT Work and Codex for eligible paid users.
- Luna is additionally available to Free and Go users through the desktop app, while the models are not yet available in Chat.
- The release combines claimed capability gains with lower operating costs, targeting broader use of coding, automation, and computer-use workloads.
Impact
The release puts pressure on competing model providers by pairing stronger claimed performance with a substantial reduction in API pricing. Lower inference costs could accelerate deployment of agentic coding and computer-use applications, where repeated model calls make economics especially important. The main market question is whether independent evaluations confirm meaningful gains over GPT-5.6 rather than only improved cost efficiency. Wider availability across paid ChatGPT tiers and Luna access for free users also expands OpenAI’s distribution advantage.
