Key point
Early testers report that Gemini 4 Carbon offers noticeably better 3D generation than Argon but runs two to four times slower, with frontend and UI capabilities remaining weak.
Details
- Gemini 4 Carbon has entered an Early Access Program (EAP) for partners and is currently being tested on LM Arena, with a public release expected soon.
- Early outputs indicate Carbon is noticeably better than Gemini 4 Argon at 3D tasks, though frontend and UI generation remains weak.
- The model is significantly slower than Argon, with testers reporting speeds roughly two to four times slower depending on the task.
- Google's Trusted Tester Agreement requires testers to keep unreleased models and outputs private, making the public sharing of Carbon results on X a breach of protocol.
- Google processed around 25 trillion tokens in the first 72 hours after the Argon launch, suggesting a need for rapid iteration to maintain momentum.
- Competitors are also preparing new models, including OpenAI's GPT-6.1 Terra and Anthropic's Fable 5.5, which are reportedly reaching partners.
