---
## 1. Model Introduction

[Llama-3.3-70B-Instruct](https://huggingface.co/meta-llama/Llama-3.3-70B-Instruct) is Meta's latest 70 billion parameter instruction-tuned language model, featuring improved performance and efficiency over Llama 3.1. With a 128K token context window and enhanced capabilities across reasoning, coding, and multilingual tasks, Llama 3.3 delivers state-of-the-art results while maintaining accessibility for production deployment.

**Key Features:**

- **Enhanced Performance**: Improved instruction following, reasoning, and task completion over Llama 3.1
- **Tool Calling**: Native support for function calling and tool use scenarios
- **Multilingual Support**: Optimized for 8 languages (English, German, French, Italian, Portuguese, Hindi, Spanish, and Thai)
- **Extended Context**: 128K token context window for processing long documents and complex tasks
- **Efficient Deployment**: 70B parameters enable deployment on single GPU with AMD MI300X

**License:**
Llama 3.3 is licensed under the Llama 3.3 Community License. See [LICENSE](https://huggingface.co/meta-llama/Llama-3.3-70B-Instruct/blob/main/LICENSE) for details.

For more details, please refer to the [official Llama models repository](https://github.com/meta-llama/llama-models).

## 2. SGLang Installation

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

For SGLang CPU installation, please refer to the [CPU version installation guide](../../../docs/hardware-platforms/cpu_server#installation).

## 3. Model Deployment

This section provides deployment configurations optimized for AMD GPUs (MI300X, MI325X, MI355X) and Intel Xeon CPUs.

### 3.1 Interactive Configuration

**Interactive Command Generator**: Use the configuration selector below to automatically generate the appropriate deployment command for your AMD GPU setup.

import { Llama33Deployment } from "/src/snippets/autoregressive/llama33-70b-deployment.jsx";

<Llama33Deployment />

### 3.2 Configuration Tips

**AMD GPU Deployment:**

- All AMD GPUs (MI300X, MI325X, MI355X) support TP=1 for both BF16 and FP8 variants
- **FP8 Model Variant**: Use AMD's optimized `amd/Llama-3.3-70B-Instruct-FP8-KV`
- **Tool Calling**: Enable with `--tool-call-parser llama3` for function calling support
- **Higher Throughput**: Optional TP=2 or TP=4 can be used for increased throughput

**Xeon CPU Deployment:**

Please refer to the `Notes` part in the serving engine launching section in [the SGLang CPU server document](../../../docs/hardware-platforms/cpu_server#launch-of-the-serving-engine) to better understand how to configure the arguments, especially for TP (tensor parallel) and NUMA binding settings.

## 4. Model Invocation

### 4.1 Basic Usage

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

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

### 4.2 Advanced Usage

#### 4.2.1 Tool Calling

Llama 3.3 70B Instruct supports native tool calling. Enable the tool parser during deployment:

```shell Command
python -m sglang.launch_server \
  --model-path meta-llama/Llama-3.3-70B-Instruct \
  --tool-call-parser llama3 \
  --tp 1 \
  --host 0.0.0.0 \
  --port 30000
```

**Python Example:**

```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": {
                    "location": {
                        "type": "string",
                        "description": "The city name"
                    },
                    "unit": {
                        "type": "string",
                        "enum": ["celsius", "fahrenheit"],
                        "description": "Temperature unit"
                    }
                },
                "required": ["location"]
            }
        }
    }
]

# Make request
response = client.chat.completions.create(
    model="meta-llama/Llama-3.3-70B-Instruct",
    messages=[
        {"role": "user", "content": "What's the weather in Tokyo?"}
    ],
    tools=tools,
    temperature=0.7
)

# Check for tool calls
message = response.choices[0].message
if message.tool_calls:
    tool_call = message.tool_calls[0]
    print(f"Function: {tool_call.function.name}")
    print(f"Arguments: {tool_call.function.arguments}")
```

**Handling Tool Call Results:**

```python Example
# After executing the function, send the result back
def get_weather(location, unit="celsius"):
    # Your weather API call here
    return f"The weather in {location} is 22°{unit[0].upper()} and sunny."

# Build conversation with tool result
messages = [
    {"role": "user", "content": "What's the weather in Tokyo?"},
    {
        "role": "assistant",
        "content": None,
        "tool_calls": [{
            "id": "call_123",
            "type": "function",
            "function": {
                "name": "get_weather",
                "arguments": '{"location": "Tokyo", "unit": "celsius"}'
            }
        }]
    },
    {
        "role": "tool",
        "tool_call_id": "call_123",
        "content": get_weather("Tokyo", "celsius")
    }
]

final_response = client.chat.completions.create(
    model="meta-llama/Llama-3.3-70B-Instruct",
    messages=messages,
    temperature=0.7
)

print(final_response.choices[0].message.content)
# Output: "The current weather in Tokyo is 22°C and sunny. A perfect day!"
```

#### 4.2.2 Long Context Processing

Leverage the 128K context window for processing long documents:

```python Example
from openai import OpenAI

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

# Example with long document
long_document = "..." * 10000  # Your long document here

response = client.chat.completions.create(
    model="meta-llama/Llama-3.3-70B-Instruct",
    messages=[
        {"role": "user", "content": f"Summarize this document:\n\n{long_document}"}
    ],
    temperature=0.7,
    max_tokens=1000
)

print(response.choices[0].message.content)
```

## 5. Benchmarking

Use the SGLang benchmarking suite to test model performance with different workload patterns:

### 5.1 Basic Benchmark Command

```bash Command
python -m sglang.bench_serving \
  --backend sglang \
  --dataset-name random \
  --num-prompts 1000 \
  --random-input 1024 \
  --random-output 1024 \
  --max-concurrency 16
```

### 5.2 Adjusting Benchmark Parameters

**Input/Output Length**: Adjust `--random-input` and `--random-output` to test different workload patterns:

- Short conversations: `--random-input 1024 --random-output 1024`
- Long outputs: `--random-input 1024 --random-output 8192`
- Long inputs: `--random-input 8192 --random-output 1024`

**Concurrency Levels**: Adjust `--max-concurrency` to test different load scenarios:

- Low concurrency (latency-focused): `--max-concurrency 1 --num-prompts 100`
- Medium concurrency (balanced): `--max-concurrency 16 --num-prompts 1000`
- High concurrency (throughput-focused): `--max-concurrency 100 --num-prompts 2000`
