🤖 Red Candle: Run LLMs Directly from Ruby — An interesting new library that uses some Rust under the hood, but with no need for Python or third party LLM APIs: just interact with the LLM right from Ruby. Supports Gemma, Llama 3, and Mistral models for now. It worked on my Mac (though the TinyLlama model in the examples is of questionable utility!) but your mileage may vary. GitHub repo.

▶ Build a Blog in 15ish Minutes with BrutRB — Rails did pretty well out of having several ‘build a blog in 15 minutes’ videos over the years, so it’s great to see one for the new Brut framework too. A great way to pick up how to use it. David Bryant Copeland |
