Putting Jeff-1 out into the world, this is an attempt at a Jev like model, built on qwen 4b. - Jeff does the job, can be ran locally. But I will say it is over confident, so id say use this to make a better jeff than me. https://huggingface.co/GestaltLabs/Jeff-1 I also included a how to train your own Jeff, this has been a cheap project as I have been able to do it on google collab entirely. It is a good first attempt, I have since had some realizations that will lead to the next version, currently in development.
