Airbnb widens access to GPT‑6 Astra and OpenAI frontier models 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.
