Why high: an exact fingerprint shared with 6 models.
Z.ai: GLM 5V Turbo is Z.ai's model, and its measured tokenizer sits in Z.ai's own signature group alongside its sibling models. No other maker's measured model shares it so far.
| We checked | What we found | Where it came from |
|---|---|---|
| How it counts tokens | Counts every one of the 50 test strings exactly like 6 other models | tk_3eaaf3e0 |
| How its API is set up | Set up identically to 1 other listing, field for field | api_6d11701b |
| How much it can read and write | Reads up to 202,752 tokens at once, writes up to 131,072 | its own listing |
| Whether it thinks before answering | Reasons when asked to | its own listing |
| Who served our requests | Z.AI | we measured it, 3 September 2026 |

We sent Z.ai: GLM 5V Turbo fifty short pieces of text and recorded what each one cost it in tokens. The bars below are those costs. Two models built on the same tokenizer produce the same bars; a model built on a different one produces a different set, which is what makes this a fingerprint.
Overhead subtracted: 5 prompt tokens.
GLM-5V-Turbo is Z.ai’s first native multimodal agent foundation model, built for vision-based coding and agent-driven tasks. It natively handles image, video, and text inputs, excels at long-horizon planning, complex coding,...
