Building a large language model from scratch requires significant expertise, computational resources, and a large dataset. The model architecture, training objectives, and evaluation metrics should be carefully chosen to ensure that the model learns the patterns and structures of language. With the right combination of data, architecture, and training, a large language model can achieve state-of-the-art results in a wide range of NLP tasks.

Glad to hear, you found it useful, Julia!
Please let me know of other topics, where we could drop a hint or two…
