As TechCrunch reports, OpenAI launched the GPT-6 Astra earlier this month, which was billed as the company's most powerful and capable model, as well as the "world's best model" for a variety of tasks including computing and programming. The lab is now expanding the GPT-6 generation with updated versions of the smaller Sol and Luna models. The company claims that “GPT-6 Astra introduced a new generation of intelligence; these models extend its benefits, making this intelligence more effective and accessible.” The first Sol and Luna series models were introduced earlier this year and represent different levels in the OpenAI model hierarchy. Sol is designed for complex tasks like programming, while Luna is more suited to clerical work—"tasks with high volume and a clear purpose, such as summarizing documents, extracting information, or answering quick questions." OpenAI also highlights significant improvements in efficiency and accessibility—particularly through significantly reduced prices for API access. The 6 Series models will be available at half the price of the 5.6 Sol and Luna Series models, which OpenAI attributes to improvements in caching and inference. The company is so
It claims that its newest models are better at producing virtually accurate answers and notes that they have lower programming error rates. “In our internal estimate of actual accuracy, based on anonymized real-life conversations where users pointed out errors in our models, GPT-6 Sol makes approximately half as many errors as its predecessor, achieving Astra-level reliability at a significantly lower cost,” the announcement states. As is typical with new OpenAI model releases, the company claims that its newest offerings are superior to those of its main competitor, Anthropic. The company has repeatedly claimed that the GPT-6 Sol and Luna perform significantly better than Anthropic's top models, such as Fable and Opus. Notably, Anthropic released the new version of Opus 5.5 just 90 minutes before OpenAI's release, reflecting the intense competition between the two companies. New versions of Sol and Luna are now available on ChatGPT Work and Codex for most paid accounts, while Luna will be available in the desktop app and for Free and Go users.
