Confidence thresholds determine how the platform categorizes each AI response into high, medium, or low confidence bands, and what minimum search relevance the orchestrator requires before it is willing to stream an answer at all. These bands drive escalation rules, dashboard metrics, and audit records — tuning them is one of the fastest ways to change how the AI assistant behaves without touching any content.

The Confidence Thresholds page combines the band slider with the Minimum Reranker Threshold control.
Confidence Bands
The upper panel displays a dual-handle slider ranging from 0% to 100%. Drag the handles to set two boundaries that split every scored response into three bands:
- High confidence — responses scoring above the upper threshold (default: 90%)
- Medium confidence — responses scoring between the two thresholds (default: 60%–90%)
- Low confidence — responses scoring below the lower threshold (default: below 60%)
The slider uses a color gradient — green for high, yellow for medium, and red for low — so you can see the relative size of each band at a glance.
Previewing the Impact
When you adjust either threshold, a reclassification preview appears below the slider. The preview analyzes the last 30 days of conversation data and shows:
- Current vs. proposed counts — how many conversations fall into each band under the current and proposed thresholds
- Reclassification impact — which conversations would move between bands (for example, from medium to low or from low to medium)
This helps you understand the effect of a change before you save it.
The preview uses 30 days of historical data. If your tenant is new or has low conversation volume, the preview may show limited results — make small threshold changes and watch the dashboard for a day or two before tightening them further.
Minimum Reranker Threshold
The second panel on the page holds a single slider labelled Minimum Reranker Threshold. This control sets the minimum search relevance score that the orchestrator requires from your knowledge base before it will generate an answer at all. It operates earlier in the pipeline than the confidence bands — the reranker threshold is a gate that decides whether a response is worth producing, whereas the confidence bands classify responses that have already been produced.
| Detail | Value |
|---|---|
| Range | 0.0 to 1.0 |
| Step | 0.05 |
| Marks | 0, 0.3, 0.5, 1.0 |
Use the slider to tune how strict the knowledge base match must be. The orchestrator compares the highest reranker score from the retrieval step against this threshold:
- If the best match meets or exceeds the threshold — the orchestrator proceeds, streams an answer, and scores it for confidence as usual
- If every result falls below the threshold — the orchestrator aborts the generation step and returns a low-confidence status without producing an answer
A higher threshold (for example, 0.7) forces the assistant to stay silent on questions where no confidently-matching content exists, which is the right choice for compliance-sensitive tenants. A lower threshold (for example, 0.2) lets the assistant attempt an answer even when the knowledge base signal is weak, which is useful for tenants with a small knowledge base that still prefer a best-effort response over nothing at all.
The Minimum Reranker Threshold affects every query, not just low-confidence ones. Raising it will reduce the total number of answers the assistant is willing to stream — monitor the dashboard's Total Requests and Success Rate metrics after any change.
Saving Threshold Changes
Adjust the Thresholds
Drag the band slider to change the High and Medium boundaries, and drag the Minimum Reranker Threshold slider to change the relevance gate. You can change one or both in the same edit.
Review the Preview
Check the reclassification preview under the band slider to confirm the impact of your proposed bands.
Save Changes
Click Save Changes at the bottom of the page. The button is disabled until you make a change. To undo your edits without saving, click Discard.
Changing thresholds affects how future conversations are classified and which escalation rules trigger. Existing audit records retain their original confidence scores, so historical data is not rewritten.
Field Reference
| Field | Description | Range | Default |
|---|---|---|---|
| High Threshold | Minimum score for the High confidence band | 0–100% | 90% |
| Medium Threshold | Minimum score for the Medium confidence band | 0–100% | 60% |
| Minimum Reranker Threshold | Minimum reranker score required before the orchestrator streams an answer | 0.0–1.0 (step 0.05) | Tenant-specific |
