He previously ran Storyteller.ai and worked as an engineer at Square. Over two days he published\nseven Rust applications, each a \"clean-room reimplementation\" of a major Adobe Creative Cloud app, and said Anthropic's Claude Opus 5.5\nwrote them. The projects spread on Reddit and Hacker News over the weekend and went viral on GitHub. A week later, on October 7, he added\nequivalents of Microsoft Word, Excel and PowerPoint, AutoCAD and Pro Tools.\n\nThe apps are early alphas. Thomas puts feature parity at about 50%.\n\n## Why it matters\n\nIt is the most visible test so far of the claim that frontier coding agents make large, established desktop software cheap to copy.\nHow much of it is truly usable, and whether it survives a legal challenge, remains to be seen.","disputed":[],"related":[{"id":"2026-09-22-claude-opus-5-5","url":"https://postcutoff.com/e/2026-09-22-claude-opus-5-5/","date":"2026-09-22","date_precision":"day","short_title":"Anthropic releases Claude Opus 5.5","deck":"Fable-5.1-level performance at $4/$20, first model of the Claude 5.5 family","takeaway":"Opus 5.5 continues the 2026 pattern of Mythos-class capability moving down into cheaper tiers.","category":"model-release","category_label":"Model releases","importance":5,"confidence":"high","status":{"key":"confirmed","labels":["Confirmed"]},"sources":36,"official":16,"filed":"2026-09-29","updated":"2026-10-05","orgs":["Anthropic"]}],"people":[],"posts":[],"videos":[],"models":[],"changes":[{"date":"2026-10-09","type":"filed","text":"Created"}],"provenance":{"agents":[{"model":"Claude Opus 5.5","maker":"Anthropic","tool":"Claude Code"}],"filed":"2026-10-09","run":null,"sources_read":null,"updated":"2026-10-09","human_review":null,"version":null},"gaps":[{"model_id":"gpt-6-astra","name":"GPT-6 Astra","cutoff":"2026-04","days_after":160,"in_training_data":false},{"model_id":"claude-opus-5-5","name":"Claude Opus 5.5","cutoff":"2026-06","days_after":99,"in_training_data":false},{"model_id":"gemini-3-8-flash","name":"Gemini 3.8 Flash","cutoff":"2026-03","days_after":190,"in_training_data":false},{"model_id":"grok-4-7","name":"Grok 4.7","cutoff":"2026-05","days_after":129,"in_training_data":false}],"short_url":null}
