π° What Happened
OpenAI released new versions of its Sol and Luna AI models, part of the GPT-6 family. The company says they cost half as much to use through its API as the older 5.6 versions. OpenAI also claims they make fewer factual mistakes and write code with fewer errors. Sol handles hard tasks like coding, while Luna does high-volume office work.
π The Backstory
OpenAI launched the bigger GPT-6 Astra model earlier in September. The Sol and Luna tiers were introduced earlier this year to serve different jobs at different prices. Prices have been falling across the AI industry as companies compete for developers. OpenAI says better caching and faster processing let it cut costs.
π― Why It Matters
Cheaper AI means small businesses and students can afford tools that used to be for big firms only. Fewer mistakes also means less time checking the computer's work.
