They wrote 20 articles that month, doubling from 10 in September, and saw followers rise from 21 to 77, page views from 303 to 989, likes from 43 to 249, and impressions from 4,386 to 27,945.\n\nThe author tried GPT‑6 on ChatGPT, then canceled ChatGPT Pro, and shifted API usage to Claude Max, cutting monthly AI spend from about 100,000 yen to about 45,000 yen. They also tested new models Gemini 4 Argon, GPT‑6.1 Terra, Genie 4, and Gemini 4 Carbon but stayed with Opus 5.5. Claude Duet was not yet available in Japan, and 1Password for Agents was adopted at no extra cost.\n\nThe review notes that Opus 5.5, released September 22, matches Fable 5.1 performance and is 20% cheaper than Opus 5. The author used it to produce videos and articles, costing about 3 yen for narration audio per 53‑second clip and 800 yen for a 35‑minute video. They plan to test Claude Duet and new Claude models in November.","keyPoints":["Opus 5.5 released September 22, priced 20% lower than Opus 5.","Author wrote 20 articles in October, doubling from 10 in September.","Author canceled ChatGPT Pro after GPT‑6 release, reducing AI spend from 100,000 yen to 45,000 yen."],"whyItMatters":"The review shows how new Claude and OpenAI models affect solo‑entrepreneur productivity and cost, illustrating adoption patterns and pricing shifts that shape AI usage for small creators.","category":{"slug":"models","name":"Generative AI & Models","url":"https://digestai.news/category/models"},"entities":{"companies":["OpenAI","Anthropic","Google","Meta","1Password"],"models":["Opus 5.5","GPT-6","GPT-6.1 Terra","Gemini 4 Argon","Gemini 4 Carbon","Claude Haiku 5.5"],"people":[]},"firstPublishedAt":"2026-10-31T03:38:00Z","updatedAt":"2026-10-31T03:38:00Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"note.com","title":"October Review | Opus 5.5 was the right choice, dots and Muse didn't fit","url":"https://note.com/leapre/n/ne53ce2efd3cd?hl=en","publishedAt":"2026-10-31T03:38:00Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":{"title":"The Race Toward Autonomous Enterprise AI","url":"https://digestai.news/thread/anthropic-opens-claude-duet-research-preview-for-us-pro-and-max-users","storyCount":6},"cite":{"text":"Digest AI, \"Author reviews Opus 5.5, dots and Muse AI secretaries\", 31 October 2026, https://digestai.news/story/author-reviews-opus-5-5-dots-and-muse-ai-secretaries","publisher":"Digest AI","title":"Author reviews Opus 5.5, dots and Muse AI secretaries","datePublished":"2026-10-31T03:38:00Z","url":"https://digestai.news/story/author-reviews-opus-5-5-dots-and-muse-ai-secretaries"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
