AI Frontier: Google Gemini-4 Argon

The era of almost frontier models means we only have one leader. SI insanity, DevDay confusion, price increases and token share disruption. Also Hegseth American Protectionism.

Gemini. It only took Google seven months (February to September) to release their next frontier model. But how many days will it be frontier level?

Hey Everyone,

So what’s going on at the AI frontier this week? I wanted to check out and round-up some of the AI news this week that caught my attention.

Frontier Models

As we anticipated, Google announced their Gemini 4 Argon model this week. Alphabet says its built to sustain deep reasoning across complex, long-horizon workflows. It’s last flagship model was way back in February and it’s difficult to understand what took them seven months to launch another one. We’ll know more on post October 1st after cybersecurity testing, but the first signs look promising.

It appears to truly put Astra GPT-6 behind us. Astra OpenAI’s frontier model was only seemingly frontier for 19 days, before Opus 5.5 was announced.

Google Gemini-4 Argon

Meanwhile in the span of 2026 Google saw another huge exodus of top AI researchers (e.g. DiscoveryLoop) and talent. It’s also not clear if Google will have an answer for the personal assistant wars of Muse, Instinct, Grok Bot and Dots. Have you tried them?

• Instinct

• Grok Bot

• Dots

The other companies most likely to make a Muse competitor for the B2C space are ByteDance and Google.
