Autonomous task execution
Starts from a user request and runs an autonomous agent to work through the task rather than only answering in chat.
Arena Agent Mode
Arena Agent Mode runs autonomous AI agents for browsing, research, coding, and other real-world tasks. It also connects to an agent leaderboard for comparing model behavior on those workflows.
Overview
Agent Mode is Arena’s interface for running autonomous AI agents on real-world tasks. The page describes it as a place to browse, research, code, and complete tasks with an agent rather than a simple chat response.
The product is tied to Arena’s broader model comparison system. Users can try models in Agent Mode and compare how they perform on agentic work through the Agent Leaderboard, which ranks models using real sessions and signals such as tool reliability, task completion, steerability, bash recovery, and tool hallucination.
Core capabilities
Multi-step work in one session
Supports browsing, research, and coding as part of the same agent workflow.
File-assisted prompting
Lets users add files to the prompt area, which suggests the agent can work from uploaded context.
Agent performance comparison
Connects to Arena’s Agent Leaderboard, where model behavior is tracked on real agent sessions.
Per-signal evaluation
Surfaces performance signals such as tool reliability, task completion, steerability, bash recovery, and tool hallucination.
Leaderboard-backed model selection
Shows a model ranking view with support for comparing multiple frontier models on agentic tasks.
Practical use cases
End-to-end task execution
Use Agent Mode when you want an AI system to carry a task forward across browsing, research, and coding steps instead of only drafting a single response.
Working from uploaded context
Use the file drop area when your request depends on supporting materials, since the page shows a way to add files before starting the agent.
Model selection and benchmarking
Use the Agent Leaderboard to compare how different frontier models behave on agentic tasks before choosing one for a workflow.
Evaluating agent behavior
Use the leaderboard signals to inspect where a model is strong or weak, such as tool reliability, task completion, steerability, or bash recovery.
