I assume you mean open weight models? I wish we had better open source models. It would make LLMs far less icky if we had nice clean open trained models. A breakthrough on the cost of training would be nice.
I'd put my work into that. Not the only option just an example.
Every great project takes time to build. It's possible.
Weights, datasets, code, multiple checkpoints...
I like their FlexOlmo concept.
