Thinking on, Z.AI's recommended sampling, same serving setup for both models. Single runs on a few hundred questions
move by about a point either way. None of these benchmarks was used to build the model.
† Measured on an earlier build of the same edit.
Effort setting
AZ-Focus works best at max or high effort, where most of the hesitation is. At low effort GLM-5.3-Flash
already thinks very little, and the edit costs accuracy without saving much (BBH 80.0% vs 83.5%, MMLU-Pro 83.0% vs
84.2%). Use the original if you run at low effort.
Usage
Same architecture, tokenizer and chat template as GLM-5.3-Flash (the template is Z.AI's, revision a6c167b, which keeps
image and video input working in engines that check for it). The routed experts are EXL3 4 bpw with the mcg
codebook; load it with an engine that supports GLM-5.3-Flash's EXL3 layout. The difference shows in thinking mode;
with thinking off, output length is unchanged.
Limitations
- Agentic coding is about 3 points below the original on SWE-bench Verified (two runs of 100 tasks). If long agent
runs are your main use, compare both on your own tasks.
- Low effort: see above.
- Other languages, very long contexts and multi-hour agent sessions haven't been measured separately yet.
