III. Implementation Guide

Recommended Deployment (vLLM)

# Installation Requirements
pip install vllm --upgrade  # Requires vLLM≥0.9.1

# Verify Dependencies
python -c "import mistral_common; print(mistral_common.__version__)"
# Should output ≥1.6.2

# Launch Service (Dual-GPU Parallel)
vllm serve mistralai/Mistral-Small-3.2-24B-Instruct-2506 \
  --tokenizer_mode mistral \
  --config_format mistral \
  --load_format mistral \
  --tool-call-parser mistral \
  --enable-auto-tool-choice \
  --limit_mm_per_prompt 'image=10' \
  --tensor-parallel-size 2

Note: Deployment requires approximately 55GB GPU memory (bf16/fp16 recommended)

Multimodal Implementation Example

from openai import OpenAI
client = OpenAI(base_url="http://localhost:8000/v1", api_key="EMPTY")

# Load System Prompt Template
system_prompt = "..."  # From SYSTEM_PROMPT.txt

# Build Multimodal Request
response = client.chat.completions.create(
  model="mistralai/Mistral-Small-3.2-24B-Instruct-2506",
  messages=[
    {"role": "system", "content": system_prompt},
    {"role": "user", "content": [
      {"type": "text", "text": "Analyze combat strategy in image"},
      {"type": "image_url", "image_url": {"url": "https://example.com/battle.png"}}
    ]}
  ],
  temperature=0.15,  # Recommended for balanced creativity
  max_tokens=131072
)

Sample Output:
“Current Pikachu (Lv42) vs. Pidgey (Lv17) recommends FIGHT:

  1. Significant level advantage (win probability >95%)
  2. Experience point rewards
  3. Low item consumption risk…”

Advanced Function Calling

# Define Calculation Tool
tools = [{
  "type": "function",
  "function": {
    "name": "my_calculator",
    "description": "Mathematical expression evaluation",
    "parameters": {
      "type": "object",
      "properties": {"expression": {"type": "string"}}
  }
}]

# Send Image-Based Math Problem
response = client.chat.completions.create(
  model=model,
  messages=[{
    "role": "user",
    "content": [
      {"type": "text", "text": "Compute all equations in image"},
      {"type": "image_url", "image_url": {"url": "https://example.com/math.jpg"}}
    ]
  }],
  tools=tools,
  tool_choice="auto"
)

# Process Tool Calls
for tool_call in response.choices[0].message.tool_calls:
  if tool_call.function.name == "my_calculator":
    expression = json.loads(tool_call.function.arguments)["expression"]
    result = eval(expression)  # Execute calculation

Typical Output:
[{"expression": "19 - (8 + 2) + 1"}, {"expression": "6 + 2 × 3"}]

IV. Transformers Integration

from transformers import Mistral3ForConditionalGeneration
from mistral_common.protocol.instruct import ChatCompletionRequest

# Load Model & Tokenizer
model = Mistral3ForConditionalGeneration.from_pretrained(
  "mistralai/Mistral-Small-3.2-24B-Instruct-2506",
  torch_dtype=torch.bfloat16
)
tokenizer = MistralTokenizer.from_hf_hub(model_id)

# Build Multimodal Input
messages = [
  {"role": "user", "content": [
    {"type": "text", "text": "Battle strategy recommendations"},
    {"type": "image_url", "image_url": {"url": image_url}}
  ]}
]
tokenized = tokenizer.encode_chat_completion(ChatCompletionRequest(messages=messages))

# Generate Output
output = model.generate(
  input_ids=torch.tensor([tokenized.tokens]),
  pixel_values=torch.tensor(tokenized.images[0]),
  max_new_tokens=1000
)
decoded_output = tokenizer.decode(output[0])

V. Optimization Best Practices

  1. Temperature Calibration
    Recommended temperature=0.15 balances creativity/accuracy (adjust to 0.2-0.3 for conversational AI)

  2. System Prompt Customization
    Always use the official SYSTEM_PROMPT.txt:

    def load_system_prompt():
        file_path = hf_hub_download(repo_id=model_id, filename="SYSTEM_PROMPT.txt")
        return open(file_path).read().format(name=model_name, today=current_date)
    
  3. Long-Context Utilization
    Leverage 131K token window with max_tokens=131072 for document processing

  4. Error Handling Protocol

    try:
        response = client.chat.completions.create(...)
    except APIError as e:
        if "CUDA out of memory" in str(e):
            print("Insufficient VRAM - Reduce tensor-parallel-size or enable memory optimization")
