GenAI Connect or GenAI Agent— how do you choose?

Faced with a choice between creating a GenAI Connect rule or a GenAI Agent, I sought advice from my network and used AI tools like Claude and Copilot. I found the distinction is simple:

GenAI Connect handles a single prompt with one response for one task, while a GenAI Agent is a managed AI worker capable of reasoning and acting across multiple steps.

Here are some key questions to help decide which solution to use:

Q: Is your AI designed to perform actions or simply generate output?

A: If your AI needs to make decisions and initiate tasks, the GenAI Agent is the best fit. If its main function is to produce content or extract information, opt for the GenAI Connect rule—it’s quicker, more straightforward, and easier to manage.

Q: Does your AI require ongoing conversations, or is the same information needed each time?

A: For scenarios where a conversational approach is necessary, choose a GenAI Agent, since it remembers conversation history and context. If you just need a one-time question or action, a GenAI Connect rule will do the job efficiently.

Q: Does your AI need to access extensive data sources, or just a handful of properties?

A: When your needs are limited to a few data points, GenAI Connect can quickly extract them from unstructured data. If your solution must pull information from multiple data sources (like case histories or system records), a GenAI Agent is necessary.

Q: Is summarizing information a requirement?

A: Both GenAI Connect and GenAI Agents can summarize data. However, if summarization is your only goal, select GenAI Connect for a simpler and faster solution.

How do you decide which AI to use?

Love the article Elaine, great subject. I also look at GenAI Connect when I need to take free form text and convert to structured data model. One example is currently a step agent has one output. If I have multiple outputs I want to capture to the case from my step agent, I have it output my content in some type of formatted response to the single output property. i then put a GenAI Connect right after the step agent and use that to extract the set of data from the output and write it to multiple case properties. We have provided feedback to product to put that capability in the agent.

You have my vote on putting this capability in the agent. What a great use case!

Thanks for starting this comparison and for framing it around practical decision criteria rather than abstract definitions.

The way you contrast GenAI Connect with GenAI Agents aligns well with how Pega positions these capabilities: GenAI Connect is best suited for bounded, single purpose interactions such as extraction, summarization, or transformation, while GenAI Agents are designed to operate across multiple steps within a governed workflow.

One useful way to think about the trade off is control versus flexibility.

GenAI Connect gives you tighter predictability and simpler governance when the task is well defined, whereas agents introduce conversational memory and reasoning, which can be powerful but must be carefully scoped to avoid unintended behavior.

Another important dimension is lifecycle management. Connect rules are often easier to test and reason about in isolation, while agents require more attention to observability and human in the loop design.

I would be interested to hear how others have made this choice in real implementations?

What signals or constraints in your projects pushed you toward one approach over the other, and where did you find the boundaries between the two were less obvious than expected?

@laucf I originally went down the path of using a GenAI Connect rule because my use case was very specific. I wanted to provide guidance to a user for a specific edge case that requires a great deal of research and is time consuming.

I pivoted to using an agent when I realized the GenAI Connect rule wouldn’t be enough. I needed the AI to not look only research and provide summaries, but also look at all of the case history and data. I also needed the user to be able to have a back and forth conversation.
