Under a new agreement, Airbnb is giving its engineering and product development teams broader access to OpenAI frontier models, including GPT‑6 Astra.
The expansion builds on Airbnb’s use of Codex and longstanding collaboration with OpenAI. Airbnb engineers use an internal AI assistant for writing software and creating remote AI agents powered by Codex and models like GPT‑5.6 Sol, Terra, and Luna.
The new agreement gives Airbnb broader access to OpenAI models through OpenAI APIs and Amazon Bedrock. It arrives amid accelerating adoption of GPT‑6 Astra among developers, builders, and enterprises, many of which were already benefiting from the improved price-performance and efficiency of GPT‑5.6 Terra and Luna.
Airbnb’s early use of GPT‑6 Astra has shown strong results beyond coding. Astra helps Airbnb engineers accelerate their work by tracking down hard bugs, shaping system designs, and brainstorming engineering approaches. 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 help support experiences across search, fraud prevention, guest and host support, and insurance claims. This deep use of AI and machine learning across its marketplace helps the company better understand what guests are looking for, identify potentially fraudulent content or claims, help guests when travel plans change, and ensure hosts get insurance payouts faster and easier.
As Airbnb brings more of the trip into one app—across homes, services, experiences, airport pickups, car rentals, and more—OpenAI frontier models can give the teams building those features more powerful tools to move faster and explore what comes next.
