AI agents need robust 'harness engineering' beyond just the model

Harness engineering is presented as a crucial aspect of building effective AI agents, focusing on the systems surrounding the language model rather than just the model itself. This approach involves creating layers of control for information, execution, and feedback to ensure safety and reliability, especially when using smaller, more error-prone models. A practical demonstration allows users to experiment with these concepts in a browser, showcasing how guardrails and review processes can mitigate risks in domains like healthcare and drug discovery.

    Harness Engineering for AI Agents: Hands On Tutorial

    <p>Most people judge an AI agent by the model inside it. Swap in a bigger model, get a better agent. That is only half the story. The other half is everything wrapped around the model: what it is allowed to look up, which actions get stopped before they happen, who signs off on t…
