Introducing Agent Mode: Agentic AI is now measured in the Arena.

Agent Mode can do deep research, create reports, generate images, build websites, debug code, and more.

It completes more complex tasks by using tools like web search, bash in a sandbox environment, image generation, file writing, and asking follow-up questions.

Frontier models are waiting for you in Agent Mode to take on real-world tasks. GPT-5.5, Claude Opus 4.7, Gemini 3.1 Pro, and top open models. Test them yourself.
