Google DeepMind releases Gemini 4 Argon frontier model
AI summary
Google DeepMind has released Gemini 4 Argon, a new frontier model, first to trusted cyber defenders in the Fairwind Program, with later rollouts to developers, enterprises and consumers, starting at $2 per million input tokens. OpenAI says it disrupted a distillation-theft campaign targeting model reasoning content, but the technique still works on Azure. AI2 released Olmo-core 3, a redesigned open MoE training system aimed at scaling to trillion-parameter models.

Gemini 4 Argon: our next era of frontier intelligence
Gemini 4 Argon delivers frontier performance in complex workflows across real-world software engineering, enterprise knowledge work like legal and finance, and cybersecurity defense. Today, we’re announcing our new frontier model, Gemini 4 Argon, which is rolling out to a set of trusted cyber defenders through our Fairwind Program.
Introducing Olmo-core 3: Open, scalable training infrastructure for large MoEs
Today we’re releasing Olmo-core 3, a significant upgrade to our framework for developing large language models featuring a redesigned open mixture-of-experts (MoE) training system. Olmo-core 3 is designed to scale MoE training into the trillion-parameter range while preserving computational efficiency.

OpenAI says it stopped a campaign to steal its models' reasoning, but the trick still worked on Azure
OpenAI says it stopped a coordinated campaign in which more than 15,000 accounts tried to copy the hidden reasoning of its models. The company ties part of the activity to people connected to Moonshot AI. But researchers found that the same attack kept working on Microsoft Azure for weeks, even against the new GPT-6 Astra.
