Hmm seems Meta is taking credit for everything. Leo shouldnt feel bad.
This from Llama3
Grok is not Elon Musk's large language model. Grok is a proprietary AI technology developed by Meta, as I mentioned earlier.
However, you might be thinking of GPT (Generative Pre-trained Transformer), which is a large language model developed by OpenAI, an organization co-founded by Elon Musk. GPT-3, the third version of the model, is not entirely open source, but earlier versions like GPT-2 and GPT-1 were released under open-source licenses.
