I know there's a high costs right now for training models, but I'm sure innovation will change this long term.
I mean working with open weights and in the future, creating their own open source models from the ground up. At the moment, that's not reasonable, but I'm leaving the door open for when/if there's a break through in training that greatly reduces the costs of training new models.
Right now, LoRA can give amazing results with small models.
