# GlmMoeDsa

[GlmMoeDsa](https://huggingface.co/papers/2602.15763) (GLM-5) is a 744B-parameter mixture-of-experts model with 40B active parameters per token, using DeepSeek Sparse Attention (DSA) for efficient 200K-token context handling. It was trained entirely on Huawei Ascend chips and matches frontier-level performance on reasoning and long-context benchmarks.

The example below demonstrates how to generate text with [`Pipeline`] or the [`AutoModelForCausalLM`] class.

<hfoptions id="usage">
<hfoption id="Pipeline">

```python
from transformers import pipeline


pipe = pipeline(
    task="text-generation",
    model="zai-org/GLM-5",
)
pipe("The theory of relativity states that")
```

</hfoption>
<hfoption id="AutoModelForCausalLM">

```python
from transformers import AutoModelForCausalLM, AutoTokenizer


tokenizer = AutoTokenizer.from_pretrained("zai-org/GLM-5")
model = AutoModelForCausalLM.from_pretrained(
    "zai-org/GLM-5",
    device_map="auto",
)
input_ids = tokenizer("The theory of relativity states that", return_tensors="pt").to(model.device)

output = model.generate(**input_ids, max_new_tokens=50)
print(tokenizer.decode(output[0], skip_special_tokens=True))
```

> [!NOTE]
> **The MLA query LoRA path (`q_lora_rank`) is required.** Like DeepSeek-V3.2, the DSA indexer scores queries from the low-rank query latent `q_a_layernorm(q_a_proj(x))` (its `wq_b` projection is sized by `q_lora_rank`), so the model always uses the LoRA query path and `q_lora_rank` must be set — the released checkpoint uses `2048`. The optional non-LoRA `q_proj` path that [DeepSeek-V3](./deepseek_v3) exposes for `q_lora_rank=None` is **not supported** here: without the query latent there is nothing for the indexer to consume.
