Citaition now measures your brand's visibility across four conversational AI engines: ChatGPT, Gemini, Perplexity, and Claude, powered by claude-haiku-4-5.

Claude is the strictest surface we measure – it searches the web less often and produces fewer citations per response than the other three engines. Adding it broadens coverage but may shift headline scores down by roughly 1 percentage point on average, reflecting the genuinely harder visibility conditions on this surface.

This is a coverage expansion, not a model replacement. Your existing data from ChatGPT, Gemini, and Perplexity is unchanged. Claude data is blended in with equal weight. A “Coverage expanded” annotation marks the date on your visibility trend chart.

We have updated the analysis model used for ChatGPT responses from gpt-4o-mini-search-preview to gpt-4o-mini.

The new model was validated through a structured dual-run campaign across twelve brands spanning four industries. Mention-rate fidelity was confirmed within the ±10 percentage-point threshold for every brand tested (worst-case delta: −0.4 pp; median: +1.0 pp).

Citation counts under the new model are lower – around 2.3 per response versus 4.4 before. This is a measurement fix, not a drop in coverage. The previous number included citations parsed from the response text, which were often unreliable; the new number counts only the sources the model returns directly. Fewer citations, but every one is verifiable.

A comparison panel showing side-by-side metrics from both models is available on your visibility tab for 30 days. A permanent annotation marks the transition date on the visibility trend chart.
