Gemini 4 Carbon is built for complex software engineering, sustained agentic work, and cybersecurity defense. It has a 1M-token context window for working with large codebases and long inputs.

On engineering tasks, Carbon carries demanding work through multiple stages, with improvements in coding, full-stack web development, and scientific reasoning. Its cybersecurity capabilities span finding vulnerabilities, validating their risk, and developing patches. [Google also reports](https://blog.google/innovation-and-ai/models-and-research/gemini-models/introducing-gemini-4-carbon/) more reliable execution of multi-step plans, fewer unsupported claims, and better collaboration when requirements are ambiguous, helping agents follow through while respecting project constraints.

Use `google/gemini-4-carbon` as the model name:
