Using Anthropic’s Opus 5.5 in Claude Projects, the author let a single “orchestrator” agent spin off additional agents to research, graph, layout, and cite data, turning weeks of work into minutes.  The resulting charts illustrate how the AI landscape has shifted from a single dominant model—GPT‑4—to a rotating lead among twenty models from Anthropic, Google and OpenAI.\n\nAccording to the post, 180 AI models now outperform GPT‑4 at its launch, and 19 of those can run on a modern smartphone.  The METR Long Horizon Benchmark shows the amount of work an AI can accomplish with a single prompt doubled eight times, growing from a four‑minute task in 2024 to 17 hours of human work by April 2026; some studies suggest the capacity may already exceed 17 weeks.  At the same time, the cost of answering a Google Proof Q&A exam fell from 30 cents per answer to four hundredths of a cent.  The author argues that these rapid gains are reshaping how people collaborate with AI, moving from chat‑based “centaur” work to autonomous agents that can generate content such as videos with minimal human direction.","keyPoints":["180 AI models now surpass GPT‑4’s launch performance, 19 can run on a modern smartphone.","METR benchmark shows work capacity doubled eight times, from a 4‑minute task in 2024 to 17 hours by April 2026.","Cost of Google Proof Q&A exam dropped from 30 cents per answer to four hundredths of a cent."],"whyItMatters":"The accelerating model improvements and falling costs enable businesses and creators to automate complex tasks, shifting workflows from manual prompting to autonomous AI agents that can produce content at scale.","category":{"slug":"models","name":"Generative AI & Models","url":"https://digestai.news/category/models"},"entities":{"companies":["Anthropic","Google","OpenAI"],"models":["GPT-4","Opus 5.5","Midjourney"],"people":[]},"firstPublishedAt":"2026-10-20T15:57:59Z","updatedAt":"2026-10-20T15:57:59Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"One Useful Thing","title":"30 Months on the Exponential (in Charts)","url":"https://oneusefulthing.org/p/30-months-on-the-exponential-in-charts","publishedAt":"2026-10-20T15:57:59Z","type":"newsletter","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":{"title":"DeepSeek's Rapid AI Service and Benchmark Race","url":"https://digestai.news/thread/deepseek-launches-search-and-fetch-apis-at-0-75-per-1-000-requests","storyCount":3},"cite":{"text":"Digest AI, \"Co-Existence released, uses Anthropic Opus 5.5 to chart 30 months of AI progress\", 20 October 2026, https://digestai.news/story/co-existence-released-uses-anthropic-opus-5-5-to-chart-30-months-of-ai","publisher":"Digest AI","title":"Co-Existence released, uses Anthropic Opus 5.5 to chart 30 months of AI progress","datePublished":"2026-10-20T15:57:59Z","url":"https://digestai.news/story/co-existence-released-uses-anthropic-opus-5-5-to-chart-30-months-of-ai"},"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.
