Base vs instruct/chat models
Most of the recent LLM checkpoints available on 🤗 Hub come in two versions: base and instruct (or chat). For example, 
tiiuae/falcon-7b and tiiuae/falcon-7b-instruct.
Base models are excellent at completing the text when given an initial prompt, however, they are not ideal for NLP tasks 
where they need to follow instructions, or for conversational use. This is where the instruct (chat) versions come in. 
These checkpoints are the result of further fine-tuning of the pre-trained base versions on instructions and conversational data. 
This additional fine-tuning makes them a better choice for many NLP tasks.  
Let's illustrate some simple prompts that you can use with tiiuae/falcon-7b-instruct 
to solve some common NLP tasks.
