The 30-Second Constraint in Clinical Workflows

When you are automating real-time clinical workflows, latency is not an optimization target. It is a hard constraint.

The doctor finishes a visit. The AI scribe generates the note. The note needs to be in the chart before the next patient walks in. That gives you maybe 30 seconds, sometimes less.

Why Most Agent Architectures Are Too Slow

Most computer use agent architectures cannot hit this window. A multi-layer agent hierarchy burns multiple model calls per action at two to four seconds each. A ten-step workflow takes a minute or more in inference time alone, before any actual clicking happens.

Even a simpler architecture with one model call per action needs about two to three seconds per step. A ten-step workflow takes twenty to thirty seconds. Possible, but tight.

Three Levers for Reducing Automation Latency

There are three levers for getting automation latency down:

Reduce the number of steps. If the agent has done this workflow before, it should know the optimal path. No exploratory clicks, no wrong turns. A ten-step exploration becomes a six-step execution.

Reduce per-step latency. This means architectural choices: fewer model calls per action, smaller models where possible, caching context between steps. Every extra model call in the loop adds seconds.

Reduce startup time. Pre-warm the environment. Keep the application open and logged in. Have the patient chart ready. Start the automation at the point of action, not from a cold desktop.

The Practical Result

We combine all three. The first time an automation runs on a new workflow type, it takes longer because the agent is learning the path. After a few runs, memory kicks in: the agent knows the route, skips the exploration, and executes the minimal set of actions needed.

The practical result: standard documentation workflows consistently complete within the required window after the initial learning period. Not by making models faster (we cannot control that), but by making the agent smarter about which actions to take and eliminating everything unnecessary.
