Golang Weekly - The smallest Go binary

The Smallest Go Binary - 5KB? — I thought this sounded a bit silly at first, especially dated April 1st, but the author (also the main maintainer of purego) had an interesting use case: they wanted to use Go’s assembler but not Go’s runtime. Turns out it’s possible, with a lot of fiddling around. Note: You will almost certainly never need to do this yourself, but it's fun to see the parts involved in doing so.

Tokenizer: Pure Go Implementation of OpenAI's Tokenizer — When you use OpenAI’s GPT, input and output is delivered in ‘tokens’ which are not the same as characters, syllables or words, but somewhere in between. Truly mindboggling.
