In 27 minutes, GPT-6 Astra creates 5K and 10K running routes from OSM data
↗
Simon Willison used ChatGPT Work with GPT-6 Astra to generate 5K and 10K running routes from OpenStreetMap data, producing GPX and GeoJSON files.
This demonstrates that large language models can now perform complex geospatial tasks by leveraging external data sources like OpenStreetMap. However, the lack of transparency about the code executed raises concerns about reproducibility and trust in AI-generated outputs.

ChatGPT Work with GPT-6 Astra used Nominatim and Overpass to locate an address and download OpenStreetMap roads and trails.
The tool generated 5K and 10K running routes and provided them as embedded visualizations and downloadable GPX and GeoJSON files.
The actual code run was not visible in the ChatGPT UI, which Simon Willison called an anti-feature.
