OpenAI's GPT-6 Astra: Peter Gostev demos 3D London and a 150k-line codebase
OpenAI · youtube · 2026-09-07
OpenAI's official channel posted a conversation with Peter Gostev on his first impressions of GPT-6 Astra:
- Generative 3D: built a dynamic 3D London that moves through different historical eras
- Large codebases: improved an app with around 150,000 lines of code
- Experience gains: more natural feedback, greater reliability, and complex tasks with less supervision
The video covers his overall take on the model's long-horizon autonomy and engineering practicality.
