AI Skills for
Gemini 4 Carbon.
Carbon is the talk of the AI world right now. Here’s the honest picture — what’s confirmed, what’s rumor — and the skills that will be ready on day one.
As of Oct 11, 2026. We update this page as news breaks.
✅ Confirmed
- Business Insider reported (Oct 9, 2026) that Google staff are testing an internal Gemini 4 build codenamed Carbon on Jetski, Google’s internal coding platform.
- Google declined to comment. No public benchmarks for Carbon exist.
- Gemini 4 “Argon” was unveiled Sep 30, 2026. Google’s internal codenames (Argon, Barium, Carbon) don’t map 1:1 to public names.
🔍 Rumor — treat with care
- One anonymous employee told BI that Carbon “feels like Opus 5.5” for coding — a single source, who added it needs more testing.
- Unknown whether Carbon ships as an Argon update or a separate Gemini 4 model.
- No release date. Google may never release it publicly under this name.
