• This is one daily response per prompt/provider pair; model output can vary between runs.
• The fixed 12-prompt Vector Databases category does not estimate general market share or brand awareness.
• Presence share and citation share are relative only to the reviewed 16-brand universe; untracked brands are excluded from those denominators.
• OpenAI, Anthropic, and Google are both evaluated brands and configured model providers; no self-provider bias correction is applied.
