> Trained using the Chinchilla formula, these models provide the highest accuracy for a given compute budget. I'm confused as to why 111 million parameter models are trained with the Chinchilla formula. Why not scale up the training data? If you're training smaller models, surely optimizing performance is better than optimizing total compute. Seems like a silly misunderstanding of the Chinchilla paper, but I'm sure I…
True. There was a good blog post published about this a few weeks ago: https://finbarr.ca/llms-not-trained-enough/ Money quote for those who don't want to read the whole thing: ''' When people talk about training a Chinchilla-optimal model, this is what they mean: training a model that matches their estimates for optimality. They estimated the optimal model size for a given compute budget, and the optimal number of t…
I'm not so convinced, especially if people are doing multiple training runs for hyperparameter tuning, cleaning data, fixing bugs, etc.
I would be very interested in knowing what portion of OpenAI's compute budget is training. I would not be surprised if it was a significant minority.
