That is an early, company-reported comparison—not proof that the plugin caused more bookings. OpenAI’s case study does not disclose the conversion rates, sample size, or detailed measurement method.
What the Radisson Hotels ChatGPT plugin does
The plugin is a hotel-discovery experience inside ChatGPT. It can show Radisson hotel suggestions on a map, with pricing and amenities, so travelers can compare options while planning. The journey then continues to Radisson’s website to complete a booking; the case study does not say that guests pay or finalize reservations inside ChatGPT.

OpenAI says that, after installing the branded plugin, users no longer need to type @RadissonHotels for ChatGPT to surface it when relevant. That describes how the experience is invoked, not a guarantee that it will appear in every travel conversation.

How well is it converting?
In its October 7, 2026 case study, OpenAI reports that the plugin’s visit-to-booking conversion rate was approximately 1.5 times Radisson’s organic-search rate during July–August 2026. The comparison is limited to that two-month period and is presented by OpenAI as an early 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 provides neither the absolute conversion rates nor the number of visits and bookings behind the comparison. It also does not precisely define the organic-search cohort or explain the full measurement method. Readers therefore cannot determine the size or statistical reliability of the difference from the published figure alone, or conclude that using ChatGPT caused the higher rate.
What the 54% advertising figure does—and does not—show
OpenAI also says 54% of recorded checkout and booking events for Radisson sponsored campaigns in ChatGPT were attributed through view-through measurement. In other words, the case study assigns those events to ad views rather than describing them as necessarily following an ad click.
OpenAI does not state the event count, attribution window, or enough methodological detail to establish how many bookings the ads added. The 54% is an attribution figure, not evidence that ads caused 54% of bookings or produced incremental lift.

Build timeline and project context
OpenAI says the plugin took six weeks to build and launch, describing the work as agentic development. The case study does not provide a project budget, team size, or technical benchmark, so the timeline should not be treated as a general estimate for building other hotel integrations.
According to OpenAI, Radisson worked with Accenture Song and OpenAI. The case study describes Accenture as an OpenAI Elite Partner and says it had supported Radisson’s direct digital channel for seven years. It does not explain the underlying APIs or MCP server in enough detail to assess the implementation architecture.
Rank #3
- Not redeemable at hotel locations, bookings over the phone or if you choose the Pay at Hotel option online.
- Redeemable online only
- No returns and no refunds on gift cards.
For scale, the case study says Radisson Hotel Group brings together ten brands across EMEA and APAC, with more than 1,640 hotels in operation and under development. That is portfolio context; OpenAI does not say how many properties were available through the plugin.
How to interpret the early results
- Conversion: The approximately 1.5-times comparison is a promising signal reported by OpenAI for July–August 2026, but the missing rates, volumes, cohort definition, and methodology prevent an independent assessment of its size or cause.
- Booking flow: ChatGPT supports discovery and comparison; the documented path leads to Radisson’s site for booking.
- Advertising: The 54% figure uses view-through attribution, which should be kept separate from click-through results and causal lift.
- Comparisons with other channels: A meaningful comparison would need the same period and conversion definitions, plus clarity on where bookings complete, what inventory and information each channel displays, and how advertising attribution is counted. OpenAI’s case study does not supply enough figures for a full numerical comparison.
