I are working on releasing a post about it: ceramic is extremely cheap and works well for broad, preliminary searches; seltz is very fast; brave has strong general internet coverage, but might not be the best for domain-specific queries like financial research; exa is particularly strong for entity and people search but can be bad at latest news, while parallel has been performing well under high concurrency.

Those are some examples. You may want to choose the best providers for your use case, that is exactly why we are building telem.ai!
