A cohort defines which calls AI QA evaluates and how many of them to sample. Configure it in the Create QA flow, then move on to resolution criteria.
QA cohort creation form with fields for cohort name, agent and call filters, and sampling percentage

The cohort creation form, where you name the cohort, filter calls, and set sampling.

1

Name the cohort

Give the cohort a unique name that indicates its purpose or filters, so it’s easy to find on the AI QA dashboard — for example, High-value customers Q4 or Support calls - week 1.

Filter calls by agent and criteria

Choose which calls to include based on the following filters:
  • Agents — Select one or more agents whose calls you want to analyze. Use this to focus on a single agent or compare performance across several.
  • Date range — The start date is required. The end date is optional; leave it blank to create a dynamic cohort that keeps adding new matching calls as they occur.
  • Call duration — Include or exclude calls by length. Filter out very short calls (for example, under 30 seconds) that carry little signal, or focus on longer calls that need more analysis.
  • Disconnection reason — Filter by disconnection reason.
  • Post-call analysis — Add custom filters based on your post-call analysis results.

Set the sampling percentage

Sampling controls how many of the filtered calls are actually analyzed, so you can manage volume and cost.
  • Percentage — The share of matching calls to include. Setting 50% analyzes half of all calls that match your filters.
  • Weekly max — A cap on how many calls are analyzed per week. Setting it to 100 keeps the cohort under 100 calls a week even if the percentage would allow more.
The weekly max is a ceiling. If the percentage yields fewer calls than the max, the percentage applies; if it yields more, the max applies.
