Here are the 11 AI agents selected for their capabilities, use cases, flexibility, and relevance to current agentic AI adoption.

#1 ChatGPT Agent

ChatGPT Agent extends ChatGPT beyond conversational assistance by enabling it to carry out multi-step tasks using a combination of reasoning, web browsing, research, and computer interaction capabilities. Instead of only providing instructions or generating an answer, the agent can work through a task, interact with websites and supported tools, and produce an outcome with the user retaining control over important actions.

It is useful for workflows that require several steps, such as researching a topic, navigating websites, gathering information, working with files, and completing online tasks. ChatGPT Agent can combine information gathering with actions in the same workflow, making it more capable than a conventional chatbot for tasks that require interaction with external systems.

For business users, ChatGPT Agent can support research, analysis, reporting, planning, data-related work, and other knowledge-intensive workflows. Users can also provide instructions and review the agent’s progress, which makes it suitable for tasks where some level of human oversight is still required.

Key Features

• Computer interaction: ChatGPT Agent can interact with websites and computer interfaces to perform actions required to complete supported tasks rather than simply explaining the steps to the user.
• Web browsing and research: The agent can search for information across the web, gather relevant material, and use the results as part of a broader multi-step task.
• Multi-step task execution: Users can provide a higher-level objective and allow the agent to determine and execute multiple actions needed to work toward the requested outcome.
• File and data handling: ChatGPT can work with supported files and information as part of agentic workflows, allowing users to incorporate documents and other data into tasks.
• Tool usage: The agent can use supported tools and external capabilities during a task, allowing it to move between information gathering, reasoning, and execution.
• Task planning: ChatGPT Agent can break a complex objective into smaller actions and determine an appropriate sequence for completing the task.
• User oversight: Users remain involved in important workflows and can monitor or intervene when an action requires confirmation, helping maintain control over agent behavior.
• Broad workflow support: Because it combines reasoning, research, browsing, and computer interaction, it can support a wider range of tasks than AI agent tools designed for only one specific function.

Pricing: ChatGPT Agent is available with eligible paid ChatGPT plans. ChatGPT Plus is $20/month, while Pro is $200/month; Business and Enterprise plans are also available.
