Earlier this month, OpenAI launched GPT-6 Astra, which it heralded as its strongest and succesful mannequin but, and the “world’s finest mannequin” for a wide range of actions, together with laptop work and coding. Now, the lab is increasing the GPT-6 technology with up to date variations of the smaller Sol and Luna fashions.
“GPT-6 Astra launched a brand new technology of intelligence; these fashions lengthen its advantages by making that intelligence extra environment friendly and accessible,” the corporate writes.
The primary fashions within the Sol and Luna sequence have been launched earlier this 12 months, representing totally different tiers in OpenAI’s hierarchy of fashions. Sol is designed for advanced duties like coding, whereas OpenAI says Luna is extra applicable for clerical work — “high-volume duties with a transparent purpose, like summarizing paperwork, extracting info, or answering fast questions.”
OpenAI can also be emphasizing huge enhancements in effectivity and affordability — most notably, through a considerable worth drop for API entry. The 6 sequence fashions can be out there at half the price of the 5.6 sequence of Sol and Luna, a worth drop that OpenAI attributes to enhancements in caching and inference.
OpenAI additionally claims that its latest fashions are higher at producing solutions which might be factually correct, and notes that they’ve a decrease error fee in the case of coding.
“On our inside factuality analysis, which is predicated on de-identified real-world conversations the place customers flagged errors by our fashions, GPT-6 Sol makes about half as many errors as its predecessor, reaching Astra-level reliability at a lot decrease price,” the announcement reads.
As is typical with OpenAI’s new mannequin releases, the corporate is claiming that its latest choices outshine these of its main competitor, Anthropic. The corporate repeatedly claims that GPT-6 Sol and Luna deal with duties considerably higher than Anthropic’s high fashions — like Fable and Opus.
Notably, Anthropic launched a brand new model of Opus 5.5 simply 90 minutes earlier than OpenAI’s launch, reflecting the extreme competitors between the 2 firms.
The brand new variations of Sol and Luna are actually out there in ChatGPT Work and Codex for many paid accounts, and within the ChatGPT API, whereas Luna can be out there within the desktop app and for Free and Go customers. OpenAI expects to roll out the fashions to ChatGPT (the app and web site) progressively all through the day.
