In short. OpenAI says ChatGPT shopping review summaries use public website reviews and that reviews and ratings are not verified by OpenAI.

Definition: OpenAI says ChatGPT may show model-generated product review summaries based on reviews from public websites. Its shopping help states that reviews and ratings are not verified by OpenAI.

Key facts

OpenAI's shopping help says a review summary highlights common user likes and dislikes drawn from reviews on public websites.
The same help article says reviews and ratings are not verified by OpenAI, so a displayed summary has no OpenAI verification status.
ChatGPT may use reviews when it considers which products fit a query, alongside the query, context, price, availability, and ease of use.
OpenAI says shopping research may use merchant product data supplied through the Agentic Commerce Protocol, publicly available product information, and other retail sources.
OpenAI's shopping research help says the system reads retailer and other public sites in real time, but information can be wrong or out of date.

What does OpenAI say about review verification?

The answer is no. OpenAI documents the review summary as a model-generated explanation of recurring likes and dislikes in reviews from public websites. The same paragraph makes the verification status explicit: reviews and ratings are not verified by OpenAI.

That statement concerns the reviews and ratings themselves. The page also says that some product labels are generated from information available to the model and are not verified statements. A review summary should therefore be read as generated product information with a stated public-web source, rather than as a review audit or an OpenAI approval.

How are public reviews used in shopping results?

OpenAI says ChatGPT can consider reviews when it decides which products are relevant to a user's intent. It also considers the query and context, such as Memory or Custom instructions, and can weigh other factors such as available options, price, and ease of use. The help page warns that not all available products will necessarily appear.

The source description is broad. It identifies reviews from public websites, while product titles and descriptions may be simplified from information received from third-party providers. Merchant and product metadata can also come directly from merchants or from third-party providers. The documentation leaves the required review platform unspecified.

What does shopping research add?

OpenAI's shopping research help describes a separate research flow for comparing products and building a buyer's guide. It may use merchant product data supplied through the Agentic Commerce Protocol, publicly available product information, and other relevant retail sources. It can compare attributes including price, features, reviews, and other key details.

The same documentation says shopping research results are based on publicly available retail sites, with product pages read directly and sources cited. It also says that shopping research reads information from retailers and other public sites in real time but can make mistakes, because prices, stock, and discounts change. Some retailers block automated access, in which case shopping research may skip those sources or rely on other sites with similar products.

These details describe how information can be collected and summarized; the review verification step remains undocumented. The explicit verification status remains the one in the shopping help: OpenAI does not verify the reviews and ratings.

What should a reader check?

OpenAI recommends verifying that products meet specific needs before purchase. For shopping research, it also tells readers to confirm the final price, taxes, fees, shipping costs, availability, size, and color on the retailer's website. Those checks address changing product information; the review summary still has the verification status stated above.

For a review claim, open the linked product or retailer page and read the underlying review material when it matters to the decision. The OpenAI documentation supports treating the ChatGPT text as a summary of public material, with possible omissions or model errors, rather than as an independently verified rating record.
