Google unveils Gemini 4 Argon and claims the top spot ahead of OpenAI and Anthropic
Behind since spring 2026, the group had promised a Gemini 3.5 Pro in May before abandoning it, judged too weak. On 30 September it presents Gemini 4 Argon, its new frontier model (the most advanced in its range), billed as superior to OpenAI's GPT-6 Astra, to Claude Fable 5.1 and to Anthropic's Claude Opus 5.5. According to Koray Kavukcuoglu, chief AI architect and vice-president of Google DeepMind, the model reaches "frontier performance in complex workflows", from software engineering to knowledge work in law and finance, through to cyber defence. Access stays restricted for now to "trusted testers" in cybersecurity, the model being judged too powerful for an immediate release. Internally, according to Bloomberg, employees doubt its real results, particularly in coding. In a single model, Google claims to have caught up several generations, while its competitors were launching dozens of them.
