A couple of weeks ago I was invited to OpenAI's headquarters for a "preview event", for which I had to sign both an NDA and a video release waiver. I suspected it might relate to either GPT-5 or the OpenAI open weight models... and GPT-5 it was!

OpenAI had invited five developers: Claire Vo, Theo Browne, Ben Hylak, Shawn @swyx Wang, and myself. We were all given early access to the new models and asked to spend a couple of hours (of paid time, see my disclosures) experimenting with them, while being filmed by a professional camera crew.

The resulting video is now up on YouTube. Unsurprisingly most of my edits related to SVGs of pelicans.
