OpenAI says Radisson Hotels’ ChatGPT plugin converted visits to bookings at approximately 1.5 times Radisson’s organic-search rate during July–August 2026. That is an early company-reported comparison, not proof that the plugin caused more bookings: OpenAI’s case study gives no sample size, absolute conversion rates, or detailed measurement methodology.
What does the Radisson Hotels ChatGPT plugin do?
The plugin helps travelers discover Radisson hotels in ChatGPT. It can show hotel suggestions on a map, let users compare prices and amenities, and then send them to Radisson’s website to complete a booking. The case study describes discovery and comparison in ChatGPT, not a completed hotel transaction inside the chat.

OpenAI says that after a user installs the branded plugin, ChatGPT can surface it when relevant without the user first typing @RadissonHotels. The case study does not describe the underlying APIs or technical architecture in enough detail to establish how the experience is implemented.
How well did it convert compared with organic search?
OpenAI reports that the plugin’s visit-to-booking conversion rate was approximately 1.5 times Radisson’s organic-search rate in July–August 2026. The comparison is limited to that period and is reported by OpenAI; it is not an independently verified result.
#1 Best Overall
- Not redeemable at hotel locations or if you choose the Pay at Hotel option online
- Redemption: Online only
- No returns and no refunds on gift cards.
The case study does not provide either channel’s absolute conversion rate, the number of visits or bookings, or a precise definition of the organic-search cohort. Without those details, the figure indicates a reported relative difference but cannot show how many additional bookings the plugin generated or whether the result would hold at a different scale or over a longer period.
What does the 54% sponsored-campaign figure mean?
OpenAI says 54% of recorded checkout and booking events for Radisson sponsored campaigns in ChatGPT were attributed through view-through measurement. In other words, the reported attribution involved ad views; the case study does not establish that every event followed an ad click.
OpenAI does not state the number of events, the attribution window, or enough methodological detail to determine how much of the activity was incremental. The 54% figure should therefore be read as an attribution result, not as evidence that ads caused 54% of bookings.

How quickly was the plugin launched, and who worked on it?
OpenAI says Radisson worked with Accenture Song and OpenAI and built and launched the plugin in six weeks. The case study characterizes the work as agentic development but does not give project cost, team size, or a technical benchmark for the schedule.

What the early results establish—and what they do not
The case study offers an initial performance signal for a conversational hotel-discovery channel: OpenAI reports a higher visit-to-booking conversion rate than Radisson organic search over two months. It also describes a path from recommendations in ChatGPT to booking on Radisson’s own site.
- Reported: approximately 1.5 times the organic-search visit-to-booking conversion rate in July–August 2026.
- Not reported: absolute channel conversion rates, sample size, statistical uncertainty, or a full definition of the comparison group.
- Reported: 54% of recorded checkout and booking events for sponsored ChatGPT campaigns attributed through view-through measurement.
- Not established: that the plugin or sponsored ads caused incremental bookings.
For a meaningful comparison with another hotel app or discovery channel, readers would need matching time periods and conversion definitions, clarity on whether bookings finish in chat or on the hotel’s site, and an explanation of how click-through and view-through ad attribution are separated.
Rank #4
- Not redeemable at hotel locations or if you choose the Pay at Hotel option online.
- Redeemable online only
- No returns and no refunds on gift cards.
