Sam Witteveen — 'Flint - The First RSI Coding Model?'
Sam Witteveen looks at Flint, Recursive's open mixture-of-experts coding model built with its automated research system, covering speed, benchmarks, the team behind it, how to run it, and a demo on an RTX PRO 6000.
Sam Witteveen tests Recursive's Flint, a fast open coding model its makers say was largely built by an automated research system.
What is it?
'Flint - The First RSI Coding Model?' went up on Sam Witteveen's channel on 23 October 2026. The video covers Flint, Recursive's first public model: a fast mixture-of-experts coding model aimed at competing with Qwen3.8 and similar open coding models.
How does it work?
Chapters cover Flint's speed, its benchmark results, how to run it, and the team behind Recursive, then finish with a hands-on demo on an RTX PRO 6000 GPU. The description links Recursive's launch post, the Hugging Face model page and an NVFP4 GGUF build.
Why does it matter?
Recursive claims its RSI (recursive self-improvement) system did much of the research behind Flint, which is a bold claim for a model people can download today. A hands-on run on local hardware helps developers judge whether the speed and coding quality hold up outside the launch post.
Who is it for?
