The higher‑end GPT‑6.1 Astra was postponed for safety reviews. Google unveiled Gemini 4 Argon, which scored 77.9% on the DeepSWE v1.1 coding benchmark (ahead of Claude Opus 5.5’s 74.2%) and 68% on the CWE‑bench v1 security test, while expanding its output token window to 1 million tokens and initially offering it through the Fairwind Program for cyber‑defense teams. Anthropic released Claude Sonnet 5.5, delivering over 30% faster response generation than Sonnet 5 and cutting effective cost by using fewer tokens; it achieved 70.6% on Terminal‑Bench 4.0, beating Opus 5.5’s 66.4%. These back‑to‑back launches compress a weeks‑long cadence of major model updates into a few days, highlighting shifting strategies around safety, early‑access programs, and cost structures for developers and businesses.","keyPoints":["OpenAI released GPT-6.1 Sol and introduced a $500/month Pro 500 plan with 25× higher usage limit.","Google launched Gemini 4 Argon, scoring 77.9% on DeepSWE v1.1 and expanding token limit to 1 million.","Anthropic unveiled Claude Sonnet 5.5, 30% faster than Sonnet 5 and achieving 70.6% on Terminal‑Bench 4.0."],"whyItMatters":"The simultaneous releases raise the performance bar for coding and security tasks while new pricing and safety delays reshape cost and availability for developers and businesses.","category":{"slug":"models","name":"Generative AI & Models","url":"https://digestai.news/category/models"},"entities":{"companies":["OpenAI","Google","Anthropic"],"models":["GPT-6.1 Sol","GPT-6.1 Astra","Gemini 4 Argon","Claude Sonnet 5.5"],"people":[]},"firstPublishedAt":"2026-10-04T15:35:00Z","updatedAt":"2026-10-04T16:55:00Z","sourceCount":2,"hasPrimarySource":false,"sources":[{"outlet":"note.com","title":"[AI News] 2026.10.04_Summary of Last Week's Latest Model Releases","url":"https://note.com/sora_data_ai/n/ndfeed8abb2b6?hl=en","publishedAt":"2026-10-04T16:55:00Z","type":"press","primary":false,"lead":true},{"outlet":"note.com","title":"[AI Summary] October 3, 2026 AI News Roundup — A daily record researched and written by AI —","url":"https://note.com/hiro924164/n/nb73833bedbf2?hl=en","publishedAt":"2026-10-04T15:35:00Z","type":"press","primary":false,"lead":false}],"sourceNotes":null,"discussions":[],"thread":{"title":"Gemini Launch Sparks AI Engineering Arms Race","url":"https://digestai.news/thread/google-announces-gemini-4-argon-frontier-model","storyCount":4},"cite":{"text":"Digest AI, \"OpenAI, Google, and Anthropic launch new AI models in late September\", 4 October 2026, https://digestai.news/story/anthropic-invests-100-million-to-train-10-000-engineers","publisher":"Digest AI","title":"OpenAI, Google, and Anthropic launch new AI models in late September","datePublished":"2026-10-04T15:35:00Z","url":"https://digestai.news/story/anthropic-invests-100-million-to-train-10-000-engineers"},"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.
