Quick Start: Loading a Model

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained(
    "mistralai/Mistral-Small-4",
    torch_dtype="auto",
    device_map="auto"  # Automatic GPU/CPU distribution
)
tokenizer = AutoTokenizer.from_pretrained("mistralai/Mistral-Small-4")

inputs = tokenizer("Explain quantum computing", return_tensors="pt").to(model.device)
output = model.generate(**inputs, max_new_tokens=256)
print(tokenizer.decode(output[0], skip_special_tokens=True))

Deployment Tiers

  • Inference API: Serverless, pay-per-request
  • Inference Endpoints: Dedicated GPU instances, production SLAs
  • TGI (Text Generation Inference): Self-hosted, optimized serving
🐳 TGI Container:
docker run --gpus all -p 8080:80 -v ./data:/data ghcr.io/huggingface/text-generation-inference:latest --model-id mistralai/Mistral-Small-4
