I also use Perplexity APIs, specifically their combined web search tool + decent models. Useful combination and easier that what I used to do: using a search API like Brave and rolling my own code to combine LLM and search.

That said I have been having too much fun running Melisearch to build a local search index for many web sites that I use for reference and combine that with a small Python app that also uses local models running on Ollama. I will probably wrap this into an example to add to one of my books: not that practical but fun.
