Noob questions (I don't know anything about LLM, I'm just a casual user of ChatGPT) - is what Mistral does better than Meta or OpenAI? - will LLM become eventually open-source commodities with little room for innovation or shall we expect to see a company with a competitive advantage that will make it the new Google? in other words, how much better can we expect these LLM to be in the future? should we expect significant progress or have we reached to diminished returns (after all, this is only statistical prediction of next word, maybe there's an intrinsic limitation of this method) - are there some sorts of benchmarks to compare all these new models?
