What Is an AI Agent Harness? How Better AI Setup Makes Agents More Reliable

Show Notes

An AI agent harness may be the most important part of an AI tool you never see. Models get most of the attention, but the real difference often comes from everything around the model: what information it can access, which tools it can use and where people need to stay in control.

In this week’s episode, Jess and Kyle unpack AI agent harnesses, the increasingly important setup behind AI agents. They explore why two tools using the same model can feel completely different, why more context is not always better, and what to look for when you are choosing an AI tool for your business. They also discuss the AI harnesses you are already using, and why the future of better, faster and cheaper AI may have less to do with the next model release than you think.
