We asked it the same everyday questions as every other model in chatmodel, one try each. This is exactly what came back.

My neighbour watered my plants for two weeks while I was away. Write a short, warm thank-you note I can leave with a small gift. Keep it under 80 words.

Dear [Neighbour's Name],

Thank you so much for watering my plants while I was away. It was such a relief knowing they were in good hands, and I came home to them looking wonderful! I really appreciate your kindness and helpfulness.

Please accept this small gift as a token of my gratitude.

Warmly,

[Your Name]

In plain words

GLM 5 is a chat assistant from Zhipu AI, the company behind the GLM models. It’s the first version of the GLM 5 line in chatmodel, and the app describes it as an advanced model.

It thinks before it answers and it reads PDFs. It doesn’t understand photos, and it doesn’t search the web.

How to get the most out of it

  1. Upload the document itself. It can read the whole thing, so there’s no need to copy parts.
  2. Ask about your situation. “I want to leave in March, what do I need to do?” beats “summarize this”.
  3. Ask for steps in order. It’s good at turning a messy task into a checklist.
  4. Double-check the rules with the official source before acting on them.

How it compares with the rest of the family

GLM 5.1 is the next version and can also read PDFs. GLM 5.2 adds photos. GLM 5.3 is a newer full model, and GLM 5.3 Flash is its lighter, quicker version. If documents are your main use, GLM 5 and 5.1 are the ones that read PDFs.

When to pick another model

To chat with a long document in one click, try PDF chat. For recent information, choose GPT 5.5.
