Did Google announce Gemini 4 with a new Argon flagship AI model in September 2026?

Yes. On September 30, 2026, Alphabet’s Google announced a new top-tier artificial intelligence model called “Argon” to anchor its Gemini 4 generation of models, according to Reuters. A company spokesperson said Argon is larger than Google’s previous advanced “Pro” models and is being provided to select cybersecurity partners, with no public release timeline given.

Google said Argon is its most performant model yet for complex workloads and compared it to frontier models such as OpenAI’s Astra and Anthropic’s Opus on key coding and cyber benchmarks. Source: Reuters.
