Summary
This weekly AI news roundup from Paul J Lipsky covers a busy week led by Google’s first look at Gemini 4 Argon and OpenAI’s annual DevDay.
Google introduced Gemini 4 Argon as its new frontier model, aimed at complex workflows, enterprise knowledge work such as legal and finance, and cybersecurity defense. Published benchmarks show it ahead of GPT-6 Astra, Claude Fable 5.1 and Claude Opus 5.5 on most tests, including knowledge-work evaluations. For now it is limited to cyber defenders and trusted testers, and the host voices some hesitation about how long it will stay ahead. Gemini also gained Skills this week.
The DevDay segment focuses on consumer-facing news. Before the event, OpenAI reportedly pulled the planned GPT-6.1 Astra release over safety concerns, now expected in October, and reduced the $200 Pro plan from 20x to 10x usage. At DevDay, OpenAI launched ChatGPT Dots, an agent that works on its own, and a Spaces feature for pages, visuals and meeting notes that deletes audio once notes are finished. GPT-6.1 Soul was also released, which OpenAI describes as offering near-Astra intelligence at a fifth of the price. It is available in Codex, ChatGPT Work and for Plus subscribers.
The video is a quick way to catch up on the week’s most important model releases, plan changes and product launches.
