Google's Gemini 4 "Carbon" model is reportedly matching Anthropic's Opus 5.5 coding performance

Google's internal Gemini 4 'Carbon' variant reportedly matches Anthropic's Opus 5.5 coding performance on its internal Jetski platform.

Business Insider reports Google is testing Gemini 4 variants Argon, Barium, and Carbon, with Carbon deployed on Google's internal coding platform Jetski and said to outperform Argon on programming, comparing to Anthropic's Opus 5.5. Argon is Google's frontier reasoning model, with Flash, Omni, and Gemma filling other roles.

Gemini 4 is almost ready, says new Google DeepMind chief

Google DeepMind’s new chief says Gemini 4 is in refinement and should launch well before year-end.

Koray Kavukcuoglu, in his first media appearance as head of Google DeepMind, told The Information that Gemini 4 is in refinement and that Google wants to release an early post-training version well before the end of 2026. Google has not shipped a new flagship since the Gemini 3 series in November 2025. A Gemini 3.5 Pro update that CEO Sundar Pichai said would arrive in June was never released; Kavukcuoglu said the company instead focused on faster Flash models. He said OpenAI’s GPT-6 and Anthropic’s Mythos models, launched since Gemini 3, outperform it. Former DeepMind lead Demis Hassabis stepped down in August.
