Airbnb Widens Access to GPT-6 Astra and OpenAI Frontier Models

Airbnb has signed a new agreement with OpenAI granting its engineering and product teams broader access to frontier models, including GPT-6 Astra, via OpenAI APIs and Amazon Bedrock. The expansion builds on existing use of Codex and models such as GPT-5.6 Sol, Terra, and Luna through an internal AI assistant for software development and remote AI agent creation. Early GPT-6 Astra deployments show productivity gains in non-coding tasks, with one user completing strategic document work in 3-4 model passes versus 20+ with prior models. Beyond development, Airbnb applies OpenAI models across search, fraud detection, guest and host support, and insurance claims processing, with ambitions to extend AI-powered capabilities across a broader travel super-app.
