       | 
       | It's notably lacking newer models (4.5 Opus, 4.6 Sonnet) and
       | models from Gemini.
       | 
       | LLMs appear to naturally progress in short leaps followed by
       | longer plateaus, as breakthroughs are developed such as chain-of-
       | thought, mixture-of-experts, sub-agents, etc.

             | asked it to make a web version and it did. (Though for some

         | also the tendency to go overboard on spamming everything with
