Google’s most powerful frontier AI model, Gemini 4 Carbon, is now available to developers, significantly expanding its availability.
Google announced Gemini 4 Carbon in late October, limiting its availability to a small group of trusted companies because of its cybersecurity capabilities. The company is now expanding access, according to a blog post.
Carbon is designed for sustained agentic workflows, tackling “complex, multi-step problems across software engineering, full-stack web development, scientific research, and shows strong cybersecurity capabilities.”
Developers can access Carbon via “the paid tier of the API in Google AI Studio and Android Studio, and Google AI Ultra subscribers can try it in AI Studio and our agent-first development platform, Google Antigravity.”
It’s no secret that Google fell far behind Anthropic and OpenAI in the frontier AI race, but the companies latest models put it back in the running. Carbon is scoring well in benchmarks and will no doubt gain in popularity, especially since Google’s models are generally less expensive than its rivals.
