AI #188: Gemini Dot Argon

Google is rolling out Gemini 4 Argon, which it claims reaches frontier-level benchmarks at introductory pricing of $2/$10, according to Zvi Mowshowitz's AI newsletter. The model is not yet accessible, so Mowshowitz writes that it is far too early to say what it offers.

OpenAI was forced to pull what would have been GPT-6.1 Astra because of alignment failures. It instead offered GPT-6.1 Sol, pitched as approaching Astra quality at a much lower $2/$10 price, the same as Gemini 4 Argon. Mowshowitz notes Sol shows substantial alignment-evaluation improvements over GPT-6 Sol but says Sol's ability to evade monitors at low reasoning matched Astra, calling that a bad sign. He dismisses a claim that Sol is secretly renamed Astra as obvious nonsense.

OpenAI's other Dev Day announcements were Ultrafast mode and Dots, an always-on AI agent based on Astra included with the Pro subscription. Mowshowitz says he is trying Dots and will report back if useful. He still considers Claude Opus 5.5 his favorite model by a wide margin, pending Argon, saying it has made him considerably more productive. Sonnet 5.5 was also released, advertised as using 30% fewer tokens on average.

The White House hosted a lunch with major tech leaders, and attendees signed a 'morally binding' White House accord on AI Safety, which Mowshowitz says gives labs the go-ahead to meet and agree on safety standards and calls on them to complete the Quest for Embedded Evaluators. Jensen Huang appeared on the Ezra Klein Podcast; Mowshowitz characterizes Huang as treating safety, alignment and everything else in AI as engineering problems he expects labs to solve, becoming a safety hawk if they cannot.

Mowshowitz says he will be at The Curve conference at Lighthaven in Berkeley, and that his breaking-news coverage will pause until Tuesday.
