That means that the most powerful models today are much more powerful than the most powerful models of a month ago, but it also means that today's fast models today are a lot more powerful than the fast models of a month ago.\n\nEven if you pay close attention to new models, 1 it's easy to focus on power at the frontier and overlook the \"93% as good and\n\nI drafted the first 90% of this blog post last Friday morning and only finished it now. Everything above is [significantly more true now](https://www.anthropic.com/news/claude-opus-5) than it was when I started writing it. So, this post is itself an example of LLM progress punishing (relatively, at least) normal-speed production.\n\nThis is a tricky subject to write about, just on an audience-relationship level. To a first approximation, there are two groups of readers: one group is paying little or no attention to the models powering the AI products they use, and the other is paying *very* close attention to them.[↩](https://www.natemeyvis.com/feed/#fnref-1)\n\nAgain, by \"professional-quality\" I don't mean \"as good as expert philosophers within their expertise,\" I mean \"comparably useful to professionally trained philosophers outside their expertise but being careful and doing their homework.\"[↩](https://www.natemeyvis.com/feed/#fnref-2)\n\nThat is, approximately two months old.[↩](https://www.natemeyvis.com/feed/#fnref-3)", "url": "https://wpnews.pro/news/try-the-very-fast-models", "canonical_source": "https://www.natemeyvis.com/try-the-very-fast-models/", "published_at": "2026-07-27 15:25:00+00:00", "updated_at": "2026-07-27 15:40:16.822811+00:00", "lang": "en", "topics": ["large-language-models", "generative-ai", "ai-products"], "entities": ["Anthropic", "Claude Opus 5", "Nate Meyvis"], "alternates": {"html": "https://wpnews.pro/news/try-the-very-fast-models", "markdown": "https://wpnews.pro/news/try-the-very-fast-models.md", "text": "https://wpnews.pro/news/try-the-very-fast-models.txt", "jsonld": "https://wpnews.pro/news/try-the-very-fast-models.jsonld"}}
