Quick Start

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

# Load model and tokenizer
model_name = "YangWu001/intervention_english"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype=torch.float16,
    device_map="auto"
)

# Example: Ask about intervention study design
prompt = """How should I design a randomized controlled trial to evaluate 
the efficacy of a novel drug for Type 2 diabetes?"""

inputs = tokenizer(prompt, return_tensors="pt").to(model.device)

# Generate response
outputs = model.generate(
    **inputs,
    max_length=512,
    temperature=0.7,
    top_p=0.9,
    do_sample=True
)

response = tokenizer.decode(outputs[0], skip_special_tokens=True)
print(response)

Advanced Usage: Research Assistance

# Example 1: Literature review assistance
prompt = """Summarize the recent advances in CAR-T cell therapy for 
hematological malignancies, focusing on efficacy and safety profiles 
from Phase II/III clinical trials in the past 3 years."""

# Example 2: Clinical trial protocol design
prompt = """Design a comprehensive Phase II clinical trial protocol for 
a novel checkpoint inhibitor in metastatic melanoma. Include:
1. Primary and secondary endpoints
2. Inclusion/exclusion criteria
3. Sample size calculation (with power analysis)
4. Statistical analysis plan
5. Safety monitoring procedures"""

# Example 3: Statistical interpretation
prompt = """I have clinical trial results with p=0.045, effect size d=0.3, 
n=120. The 95% CI for the treatment effect is [0.02, 0.58]. How should I 
interpret these findings in terms of clinical significance? What are the 
implications for clinical practice?"""

# Example 4: Regulatory guidance
prompt = """What are the key FDA requirements for accelerated approval 
of oncology drugs? What endpoints are acceptable and what post-marketing 
commitments are typically required?"""

# Generate responses
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)

📚 Knowledge cutoff: Training data may not include the most recent research developments (post-2024)
🔍 Domain boundaries: Performance is optimized for biomedical interventions; may be less accurate for basic science or non-intervention research
🎯 Specialized focus: Better at clinical trials and intervention research than laboratory/bench research

Optimization Tips

Memory Optimization

# Load model with reduced precision
model = AutoModelForCausalLM.from_pretrained(
    "YangWu001/intervention_english",
    torch_dtype=torch.float16,  # Half precision
    device_map="auto",
    low_cpu_mem_usage=True
)

# Optional: 8-bit quantization for even lower memory
from transformers import BitsAndBytesConfig
quantization_config = BitsAndBytesConfig(load_in_8bit=True)

model = AutoModelForCausalLM.from_pretrained(
    "YangWu001/intervention_english",
    quantization_config=quantization_config,
    device_map="auto"
)

Speed Optimization

# Faster generation with adjusted parameters
generation_config = {
    "max_new_tokens": 512,
    "temperature": 0.7,
    "top_p": 0.9,
    "top_k": 50,
    "repetition_penalty": 1.1,
    "do_sample": True,
    "num_beams": 1,  # Greedy decoding (faster)
    "pad_token_id": tokenizer.pad_token_id,
}

outputs = model.generate(**inputs, **generation_config)

Batch Inference

# Process multiple queries efficiently
prompts = [
    "Explain Phase I trial objectives",
    "What is intention-to-treat analysis?",
    "Define non-inferiority margin"
]

# Batch tokenization
inputs = tokenizer(prompts, return_tensors="pt", padding=True).to(model.device)

# Batch generation
outputs = model.generate(**inputs, max_length=256)
responses = [tokenizer.decode(out, skip_special_tokens=True) for out in outputs]

Configuration	Tokens/sec	Quality	VRAM
FP32, greedy	~15	Good	4GB
FP16, greedy	~30	Good	2GB
