Tried depth-upscaling Cosmo-1b by duplicating 6 layers, then LISA-training on a dataset reasonably similar to the original one in an attempt to 'self-repair'.

Not sure if it worked out exactly how I pictured but the nous eval's not overall much worse than the original at least.

(Took I think about 8 hours for, I want to say, ~80 million tokens on one RTX 3090?)

Thought about doing LORA first but I couldn't get peft_layers_to_transform working on axolotl and decided to go straight to LISA.

It's probably good(?) for (random selection of layers) to get experience trying to work around (random thick doubled layers) in some kind of brain-exercise sense anyway.

Capabilities assessment vs original and upscaled version:

I'm not sure this helped.
