I do not, but John's old videos on the idea of making a language and addressing the modern problems of archaic languages has been cited many times.

Here is a list with his videos where he goes from conception to something tangible: https://www.youtube.com/watch?v=TH9VCN6UkyQ&list=PLmV5I2fxai...

The first video is from September 17, 2014.

Zig's first commit was Aug 5, 2015.

Odin has first commit in Jul 7, 2016.

tbf there was a general systems language renaissance circa 2015, following Mozilla sponsoring Rust in 2009 and its impending 1.0 in 2015. Jai, Zig, and Odin were all contemporaries in that wave.

The language is in closed beta, there isn't exhaustive details available. You can see interviews and some details on YT if you look up Jon(athan) Blow with suitable topics.

I meant that I had not heard that both Zig and Odin were inspired by Jai

Oh at least ginger bill does, I remember bill talking about odin's context feature which was loosely inspired by jai.
