# Why AI Models Should Be Matched to Each Task

Having **AI models matched to each task** means document reading, app building, and ticket answering do not all run on the same model. Each job has different requirements, and the best model for one is rarely the best for another.

## Why a single model underperforms

Treating AI as one capability means accepting a compromise on every task.

- A model strong at reasoning used for simple extraction
- A fast model used where accuracy matters more than speed
- Capability that improves elsewhere but never reaches your tool
- No way to benefit from a new model without migrating

## Different jobs, different requirements

- **Document reading** — accurate extraction from varied layouts
- **App building** — reasoning about structure and asking good questions
- **Ticket answering** — following a knowledge base faithfully
- **Classification** — consistency across thousands of similar cases
- **Combinations** — several models working together on one job

## How this works in Jestor

1. Use the **AI** features in **Jestor** without selecting a model — the appropriate one is chosen per function.
2. Note that models are updated periodically as better options become available.
3. Retest features you evaluated months ago; the underlying models have changed.
4. Track consumption on the usage page, with pages processed metered separately.
5. Expand agent use to another process once the first one performs reliably.

## Why choose Jestor for AI that improves?

**Jestor** combines models rather than committing to one, and updates them over time — so a capability evaluated six months ago is not the capability available today.

That matters practically: teams that tested an agent early and found it lacking are usually testing a materially different system if they try again.

## Frequently Asked Questions

### Do I choose the model myself?

No, the appropriate one is selected per function. See [jestor.com](https://jestor.com/?ref=blog.jestor.com).

### Are models updated over time?

Yes, periodically, as better options become available.

### Should I retest features I tried before?

Yes — the underlying models have improved.
