The company highlighted a new “Effort” setting that lets users choose how deeply the model thinks, and cited an example where the model rewrote legacy code with near‑top‑tier accuracy while saving time and money.\n\nOpenAI revealed on the same day—reportedly only about 90 minutes later—that it is launching two GPT‑6 variants, Sol and Luna, each priced at roughly half of previous models. Sol is aimed at tasks requiring deep reasoning such as writing or coding, while Luna targets high‑volume, lighter tasks like document summarisation. OpenAI also said hallucination rates have dropped, though the models now more often refuse to answer when uncertain.\n\nBoth announcements stress affordability over raw intelligence, a shift that could make generative AI more accessible for everyday work and personal use. The simultaneous price cuts suggest a competitive push to broaden adoption among users who were previously deterred by cost.","keyPoints":["Anthropic's Claude Opus 5.5 promises near‑top‑tier performance with lower pricing and an \"Effort\" depth setting.","OpenAI introduced GPT‑6 Sol and Luna, each priced at about half of earlier models.","OpenAI reports reduced hallucinations but increased refusal to answer uncertain queries."],"whyItMatters":"Lower‑cost, high‑performing models can expand AI adoption in businesses and among consumers, while the shift toward cautious answering may affect reliability expectations.","category":{"slug":"models","name":"Generative AI & Models","url":"https://digestai.news/category/models"},"entities":{"companies":["Anthropic","OpenAI"],"models":["Claude Opus 5.5","GPT-6 Sol","GPT-6 Luna"],"people":["Naoki Theme"]},"firstPublishedAt":"2026-09-22T13:40:00Z","updatedAt":"2026-09-24T09:30:00Z","sourceCount":14,"hasPrimarySource":false,"sources":[{"outlet":"note.com","title":"Gentle AI Newspaper - For those in their 50s and 60s / Easy for beginners","url":"https://note.com/happy_quail3968/n/n988bf808399c?hl=en","publishedAt":"2026-09-24T04:01:00Z","type":"press","primary":false,"lead":true},{"outlet":"finance.yahoo.com","title":"OpenAI's GPT-6 Just Got 50% Cheaper — Box CEO Says AI Agent Opportunity Could 'Dramatically' Expand: 'What an Insane Day'","url":"https://finance.yahoo.com/technology/ai/articles/openais-gpt-6-just-got-163017280.html","publishedAt":"2026-09-24T09:30:00Z","type":"press","primary":false,"lead":false},{"outlet":"note.com","title":"The End of GPTs and the New Direction of ChatGPT Shown by GPT-6: AI Shifts from 'Smart Chat' to 'AI That Does Work'","url":"https://note.com/kotori_gadget/n/n3fb957b2b0d8?hl=en","publishedAt":"2026-09-24T08:09:00Z","type":"press","primary":false,"lead":false},{"outlet":"note.com","title":"OpenAI's New Models 'GPT-6 Sol' and 'Luna' Arrive!
