BNF (Backus-Naur Form) is a metasyntax notation: it formally specifies the context-free grammar (syntax) of a programming language or communication protocol.

BNF, or Backus-Naur Form, is the foundational metasyntax used to define the formal grammar of a language, first introduced by John Backus and Peter Naur for the Algol 60 report in 1960. The notation employs *production rules* to specify how a non-terminal symbol (e.g., ) can be expanded: the rule ::= expansion states that the symbol on the left can be replaced by the sequence of symbols on the right. Terminals (literal characters like `+` or `if`) and non-terminals comprise the expansion, with the vertical bar (`|`) indicating alternatives. This precise, recursive structure enables parser generation and serves as the basis for modern extensions like EBNF and ABNF.

### [You don't need the Internet to use an LLM](https://nashville.aitinkerers.org/talks/rsvp_-iX7E_vYXM4)

This demo shows multiple ways to leverage the power of LLMs without interacting with remote web services. The models will be run in a local and portable manner, covering how to tweak the parameters used to dictate how various models run in resource-constrained environments.
