“I was surprised that GLM 5.1 5.2 are not vision models - they are text input only. That's actually pretty uncommon these days. All of the OpenAI Anthropic Gemini models accept images, and so do the other leading open weight families - Gemma 4, Qwen 3.6, Kimi 2.x. In GLM's case image input would be useful because it's a model that scores very highly for tasks like web design, but without image input it can't take a screenshot and output HTML+CSS. Don't get me wrong, GLM is a phenomenal model, bu…”
