Summary
Section titled “Summary”Human in the loop is described as a design pattern in which an agent pauses for human approval before taking its next action. Production agents can handle routine tasks while seeking human input for high-stakes actions. The examples include asking permission to upload a video or send a message on someone’s behalf. The speakers add that strong teams do not aim for full autonomy immediately, but instead design systems that divide work intelligently between humans and agents.
Key points
Section titled “Key points”- Human in the loop is a design pattern for pausing an agent until a human approves its next action.
- Production agents can handle routine work without interrupting the human.
- Human approval is most useful for high-stakes actions.
- Uploading a video is given as an example of an action an agent might ask permission to take.
- Sending a message on someone’s behalf is another example that may warrant human involvement.
- The speakers caution against aiming for full autonomy on day one.
- Teams can design systems to divide work intelligently between humans and agents.

| 00:35 | Dividing work between humans and agents | The speakers argue that teams should not seek full autonomy immediately, but should intelligently divide work between humans and agents. |

Full transcript (original language)
Section titled “Full transcript (original language)”00:00 What is human in the loop? - I’m glad I don’t have this one. - I should have given Sean this one. I would say that human in the loop is sort of a design pattern where the agent pauses and waits for a human to approve before sort of like taking the next action. I think the best production agents use this very deliberately, right? So like you’ll let the agent handle the routine and you only interrupt for like a really high stakes action. For example, like, hey Sean, is it cool if I upload this video to YouTube? - Yeah. - Okay, not bad. How about if I send this message on your behalf to Harrison?
00:35 Probably not. I’d say the best teams, sort of like shipping the best agents, just aren’t really going for a full autonomy on day one. There’s sort of like building systems where humans and agents can divide the work very intelligently.
