> Our strongest frontier model, Gemini 4 Carbon, is now available.
> 
> Built for deeply complex, long-horizon workflows that push a frontier model’s intelligence, Carbon delivers frontier performance in agentic workflows across complex knowledge work, software engineering and web development, cybersecurity, and scientific reasoning.
> 
> While Gemini 4 Argon remains the ideal model for the majority of software engineering and knowledge work, Carbon steps in for your hardest tasks that push a model to its limits — from complex, multi-step debugging to open-ended scientific research.
> 
> Available starting today:
> — Consumers: use it in the @GeminiApp and AI Mode in Search for Google AI Ultra subscribers
> — Developers and Enterprises: build via the API in @GoogleAIStudio and @AndroidStudio, Google @Antigravity for Google AI Ultra subscribers, and Gemini for business
> — Scientists and Researchers: apply for a chance to get 6 months free via @Antigravity
> — Cybersecurity Defenders: apply to join the Fairwind Program for access to Carbon for cyber
> 
> Watch how Carbon brings reasoning and coding together, turning avian research into an interactive 3D simulation of a songbird’s vocal organ that synthesizes the sounds of six bird species live.
