**License:** MIT

## 2. SGLang Installation

Please refer to the [official SGLang installation guide](../../../docs/get-started/install) for installation instructions.

## 3. Model Deployment

This section provides deployment configurations optimized for different hardware platforms and use cases.

### 3.1 Basic Configuration

**Interactive Command Generator**: Use the configuration selector below to automatically generate the appropriate deployment command for your hardware platform, quantization method, and capabilities. SGLang supports serving GLM-5.1 on NVIDIA H100, H200, B300, GB300, and AMD MI300X/MI325X/MI355X GPUs.

import { GLM51Deployment } from '/src/snippets/autoregressive/glm-51-deployment.jsx'

<GLM51Deployment />

<Warning>
  All recipes here run the DSA indexer top-k on the default `--dsa-topk-backend sgl-kernel`. Other top-k backend choices have not been fully validated on GLM-5.1.
</Warning>

### 3.2 Configuration Tips

- Speculative decoding (MTP) can significantly reduce latency for interactive use cases.
- **DP Attention**: Enables data parallel attention for higher throughput under high concurrency. Note that DP attention trades off low-concurrency latency for high-concurrency throughput — disable it if your workload is latency-sensitive with few concurrent requests.
- The `--mem-fraction-static` flag is recommended for optimal memory utilization, adjust it based on your hardware and workload.

- **H100 and H200**: FP8 is the recommended deployment path.
- **B300 and GB300**: NVFP4 is the recommended deployment path. Use `nvidia/GLM-5.1-NVFP4` with `--quantization modelopt_fp4`. Use `tp=8` on B300 and `tp=4` on GB300. The CUDA 13 image variant is required for B300 and GB300.
- **AMD GPUs**: BF16 and FP8 checkpoints run on MI300X/MI325X/MI355X at tp=8. On MI355X (gfx950), the MXFP4 checkpoint `amd/GLM-5.1-MXFP4` is also supported at tp=4 with `--kv-cache-dtype fp8_e4m3`. All AMD paths pass `--dsa-prefill-backend tilelang --dsa-decode-backend tilelang`, `--chunked-prefill-size 131072`, and `--watchdog-timeout 1200` (20 minutes for weight loading). FP8 uses approximately half the memory of BF16 (~89 GB/GPU vs ~175 GB/GPU). EAGLE speculative decoding is supported on AMD GPUs: MI300X/MI325X (gfx942) and MI355X (gfx950), but it **requires `--disable-custom-all-reduce`** — the aiter custom all-reduce kernel deadlocks during EAGLE verify at high concurrency, so without this flag the server will hang.
- For other configuration tips (MTP, DSA kernel, Context Parallel, HiSparse, NVFP4, Index Cache), see the [DeepSeek-V3.2 cookbook page](../DeepSeek/DeepSeek-V3_2). GLM-5.1 and DeepSeek-V3.2 share the same model structure, so the optimization techniques are common.
- Use `--json-model-override-args '{"index_topk_pattern": "FFSFSSSFSSFFFSSSFFFSFSSSSSSFFSFFSFFSSFFFFFFSFFFFFSFFSSSSSSFSFFFSFSSSFSFFSFFSSS"}'` to enable the [IndexCache](https://github.com/THUDM/IndexCache) method for GLM-5.1. This can improve serving efficiency with only a small accuracy loss. If you are running rigorous accuracy evaluations, do not enable this feature.

### 4.3 Basic Usage

For basic API usage and request examples, please refer to:

- [SGLang Basic Usage Guide](../../../docs/basic_usage/send_request)

### 4.4 Advanced Usage

#### 4.4.1 Reasoning Parser

GLM-5.1 supports Thinking mode **by default**. Enable the reasoning parser during deployment to separate the thinking and content sections. The thinking process is returned via `reasoning_content` in the streaming response.

To disable thinking and use Instruct mode, pass `chat_template_kwargs` at request time:

- **Thinking mode** (default): The model performs step-by-step reasoning before answering. No extra parameters needed.
- **Instruct mode** (`{"enable_thinking": false}`): The model responds directly without a thinking process.

**Example 1: Thinking Mode (Default)**

Thinking mode is enabled by default. The model will reason step-by-step before answering, and the thinking process is returned via `reasoning_content`:

```python Example
from openai import OpenAI

client = OpenAI(
    base_url="http://localhost:30000/v1",
    api_key="EMPTY"
)

# Thinking mode is enabled by default, no extra parameters needed
response = client.chat.completions.create(
    model="zai-org/GLM-5.1-FP8",
    messages=[
        {"role": "user", "content": "Solve this problem step by step: What is 15% of 240?"}
    ],
    max_tokens=2048,
    stream=True
)

# Process the stream
has_thinking = False
has_answer = False
thinking_started = False

for chunk in response:
    if chunk.choices and len(chunk.choices) > 0:
        delta = chunk.choices[0].delta

        # Print thinking process
        if hasattr(delta, 'reasoning_content') and delta.reasoning_content:
            if not thinking_started:
                print("=============== Thinking =================", flush=True)
                thinking_started = True
            has_thinking = True
            print(delta.reasoning_content, end="", flush=True)

        # Print answer content
        if delta.content:
            # Close thinking section and add content header
            if has_thinking and not has_answer:
                print("\n=============== Content =================", flush=True)
                has_answer = True
            print(delta.content, end="", flush=True)

print()
```

**Output Example:**

```text Output
=============== Thinking =================
1.  **Understand the Goal:** The user wants to find 15% of 240, and they want the solution explained step-by-step.

2.  **Identify the Core Mathematical Concept:** "Percent" means "per hundred" or "out of 100". Finding "X% of Y" translates to the mathematical operation: $(X / 100) \times Y$.

3.  **Step-by-Step Breakdown:**
    *   *Step 1: Convert the percentage to a decimal (or fraction).* 15% means 15 out of 100, which is $15/100$ or $0.15$.
    *   *Step 2: Multiply the decimal by the given number.* Multiply $0.15$ by $240$.
    *   *Step 3: Perform the calculation.*
        *   $0.15 \times 240$
        *   I can break this down further to make it easy to follow:
            *   $0.10 \times 240 = 24$ (which is 10%)
            *   $0.05 \times 240 = 12$ (which is 5%, half of 10%)
            *   $24 + 12 = 36$
        *   Alternatively, standard multiplication:
            *   $240 \times 15 = 3600$
            *   Move decimal two places left -> $36$
    *   *Step 4: State the final answer clearly.*

4.  **Draft the Response (incorporating the steps clearly):**
    *   *Introduction:* State the problem clearly.
    *   *Step 1:* Explain how to convert 15% to a decimal.
    *   *Step 2:* Explain the multiplication step.
    *   *Step 3:* Show the actual math (I'll provide the standard multiplication and the "mental math" trick as it adds value).
    *   *Conclusion:* Give the final answer.

5.  **Refine the Output (Self-Correction/Polishing during drafting):**
    *   *Drafting Step 1:* To find 15% of 240, first convert 15% into a decimal. Since percent means "per hundred," you divide 15 by 100. 15 ÷ 100 = 0.15.
    *   *Drafting Step 2:* Next, multiply this decimal by the number you are finding the percentage of (which is 240). So, calculate 0.15 × 240.
    *   *Drafting Step 3 (Standard way):* 0.15 × 240 = 36.
    *   *Adding the alternative mental math way:* It's often helpful to break it down into 10% and 5%.
        *   10% of 240 = 24 (move the decimal point one place to the left)
        *   5% is half of 10%, so half of 24 = 12
        *   Add them together: 24 + 12 = 36.
    *   *Final Answer:* 15% of 240 is 36.

6.  **Final Review against User Prompt:** Does it solve the problem? Yes. Is it step-by-step? Yes. Is it clear? Yes. (Proceed to generate output).
=============== Content =================
Here is the step-by-step solution to find 15% of 240:

**Step 1: Convert the percentage to a decimal.**
To convert a percentage to a decimal, divide it by 100 (or simply move the decimal point two places to the left).
* 15% = 15 ÷ 100 = **0.15**

**Step 2: Multiply the decimal by the number.**
Now, multiply the decimal (0.15) by the number you are finding the percentage of (240).
* 0.15 × 240 = **36**

*(Alternative mental math method for Step 2)*:
If you don't want to multiply by 0.15 directly, you can break 15% down into 10% and 5%:
* **10% of 240** = 24 (just move the decimal point one place to the left)
* **5% of 240** = 12 (5% is half of 10%, so just divide 24 by 2)
* **Add them together**: 24 + 12 = **36**

**Answer:**
15% of 240 is **36**.
```

**Example 2: Instruct Mode (Thinking Off)**

To disable thinking and get a direct response, pass `{"enable_thinking": false}` via `chat_template_kwargs`:

```python Example
from openai import OpenAI

client = OpenAI(
    base_url="http://localhost:30000/v1",
    api_key="EMPTY"
)

# Disable thinking mode via chat_template_kwargs
response = client.chat.completions.create(
    model="zai-org/GLM-5.1-FP8",
    messages=[
        {"role": "user", "content": "What is 15% of 240?"}
    ],
    extra_body={"chat_template_kwargs": {"enable_thinking": False}},
    max_tokens=2048,
    stream=True
)

# In Instruct mode, the model responds directly without reasoning_content
for chunk in response:
    if chunk.choices and len(chunk.choices) > 0:
        delta = chunk.choices[0].delta
        if delta.content:
            print(delta.content, end="", flush=True)

print()
```

**Output Example:**

```text Output
15% of 240 is 36.

Here is how to calculate it:
1. Convert the percentage to a decimal: 15% = 0.15
2. Multiply the decimal by the number: 0.15 × 240 = 36
```

#### 4.4.2 Tool Calling

GLM-5.1 supports tool calling capabilities. Enable the tool call parser during deployment. Thinking mode is on by default; to disable it for tool calling requests, pass `extra_body={"chat_template_kwargs": {"enable_thinking": False}}`.

**Python Example (with Thinking Process):**

```python Example
from openai import OpenAI

client = OpenAI(
    base_url="http://localhost:30000/v1",
    api_key="EMPTY"
)

# Define available tools
tools = [
    {
        "type": "function",
        "function": {
            "name": "get_weather",
            "description": "Get the current weather for a location",
            "parameters": {
                "type": "object",
                "properties": {

                    },
                    "unit": {
                        "type": "string",
                        "enum": ["celsius", "fahrenheit"],
                        "description": "Temperature unit"
                    }
                },
