Airbnb has entered a new agreement to provide its engineering and product development teams with broader access to OpenAI frontier models, including GPT-6 Astra. This expansion builds on the company's existing use of Codex and collaboration with OpenAI, extending access through OpenAI APIs and Amazon Bedrock.

  • Airbnb engineers utilize an internal AI assistant powered by Codex and models like GPT-5.6 Sol, Terra, and Luna for software writing and remote AI agents.
  • Early testing of GPT-6 Astra showed strong results beyond coding, with one user achieving impressive output in 3–4 passes compared to 20+ rounds with other models.
  • The company uses OpenAI models to support search, fraud prevention, guest and host support, and insurance claims across its marketplace.

This deep integration of AI helps Airbnb better understand guest needs, identify fraudulent content, and streamline processes as the company consolidates trip services into a single app.
