Under a new agreement, Airbnb is providing its engineering and product development teams with broader access to OpenAI's frontier models, including GPT-6 Astra. This expansion builds on Airbnb's use of Codex and its longstanding collaboration with OpenAI. Airbnb engineers currently use an internal AI assistant for writing software and creating remote AI agents, powered by Codex and models such as GPT-5.6 Sol, Terra, and Luna. The new agreement gives broader access to these models through OpenAI APIs and Amazon Bedrock.

Airbnb Expands Access to OpenAI Frontier Models, Including GPT-6 Astra
In engineering workflows, GPT-6 Astra has been used to assist with debugging, system design, and brainstorming. In one test involving strategic documents and other non-coding work, one Airbnb user reported reaching impressive output in 3–4 passes, compared with 20+ rounds using other models.
Airbnb also uses OpenAI models to support experiences across search, fraud prevention, guest and host support, and insurance claims. The use of these models helps improve guest experience during travel plan changes and helps accelerate insurance payouts for hosts.
