Different products use different models, sources and context. Answers can also change between sessions in the same product. Compare the exact questions and citations before drawing a conclusion about why the brands differ.
Apply it to your business
Keep separate observations for each product and surface. Do not label one API response as a measurement of every consumer interface from that provider. Compare exact citations and record missing collections separately.
