I can't speak for what you consider sucking, but there is a significant difference between Mistral and Kimi or Gemini. I find the others to be usable for my needs.
Is it not? It's html and javascript. And not even attempting to draw details that other models do.
When I try other html / js prompts it also lacks behind china models from over half a year ago. I mean worse then GLM 4.7.
