# Very Long-Running Agents

## Very Long-Running Agents

By late 2026, deploying AI agents that run continuously for **days or even a full week** to complete complex tasks becomes standard practice.

### Where we are today
Researchers are already achieving **20–30 hour continuous runs**. The trajectory to multi-day is short.

### Compute scale
These agents will burn **millions of tokens in the background** per task. This is the cost regime where local tokenization (see [[prereq-llm-context-tokenization]]) and infrastructure matter.

### Workflow inversion
The traditional human-as-producer model **inverts**:

- Humans are **no longer primary producers** of work
- Humans become the **bottleneck** (see [[claim-humans-as-bottleneck]] and the supporting [[quote-humans-bottleneck]])
- The new human role: **review work, assign tasks, exercise good taste** to determine if agent output meets standard

### Open problem
Monitoring these agents is unsolved — see [[open-question-agent-monitoring]] and the recommended response in [[action-prepare-agent-monitoring]].
