Short answer
Where available, OpenAI may estimate attribution for conversions it can't link directly, using aggregated patterns. Reported totals may include these modeled conversions, so they can differ from what your own systems record.
Sanity checks
- Compare Ads Manager conversions with CRM records for the same dates and time zone
- Track leads by UTM in your CRM independently
- Watch for sudden jumps when consent rates change
- Use the same yardstick across all channels
