# Sensitivity Levels

> Tuning the strictness of Krixai detection models

### Sensitivity Levels

Krixai allows you to adjust the sensitivity of its detection models to balance false positives and false negatives for your specific use case.

| Level              | Behavior                                  | False Positive Rate | Use Case                                                             |
| ------------------ | ----------------------------------------- | ------------------- | -------------------------------------------------------------------- |
| `low`              | Only catch high-confidence attacks (>95%) | Very low            | High-traffic consumer apps where blocking legitimate users is costly |
| `medium` (default) | Balanced detection (>85% confidence)      | Low                 | Most applications                                                    |
| `high`             | Aggressive detection (>70% confidence)    | Moderate            | Regulated industries, sensitive data environments                    |
| `paranoid`         | Catch everything remotely suspicious      | Higher              | Internal tools, legal/compliance environments                        |

### Overriding Sensitivity via Header

You can configure the default sensitivity in your dashboard, or override it on a per-request basis:

```bash theme={null}
# Set sensitivity per-request
curl https://api.krixaisecurity.com/v1/chat/completions \
  -H "X-Krixai-Key: kx-live-..." \
  -H "X-Krixai-Sensitivity: high" \
  ...
```
