I wish they wouldn't call them "open source models". They aren't open source. They didn't publish the training data. They didn't publish the tools they used to train the model. They published the weights. It's an "open weight model", a term that it seems nearly everyone has agreed is appropriate. Why is this company not using it?
Sorry, where exactly is "data" in "source"? I can understand not wanting to call it open source if they don't give you the algorithm and software used for training, but wanting the training data too? That's completely different
You can‘t reproduce the LLM without the same data
