Why high: an exact fingerprint shared with 8 models.
Z.ai: GLM 5 Turbo is Z.ai's model, and its measured tokenizer sits in Z.ai's own signature group alongside its sibling models. Measured models from Aion Labs carry the same vocabulary, which reads as reuse of Z.ai's tokenizer line and questions nobody's authorship; they are listed under "Shares this fingerprint" below.
| We checked | What we found | Where it came from |
|---|---|---|
| How it counts tokens | Counts every one of the 50 test strings exactly like 8 other models | tk_133b086c |
| 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 5 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-5 Turbo is a new model from Z.ai designed for fast inference and strong performance in agent-driven environments such as OpenClaw scenarios. It is deeply optimized for real-world agent workflows...
