+
+> **AMD Developer Hackathon 2026** · Trained on AMD Instinct™ MI300X · ROCm 7.2
+
+## Model Description
+
+OncoAgent v1.0 9B is a **QLoRA fine-tuned LoRA adapter** built on top of [Qwen/Qwen3.5-9B](https://huggingface.co/Qwen/Qwen3.5-9B), specialized for **clinical oncology triage and treatment recommendation**.
+
+This is the **Tier 1 (fast triage)** model in the OncoAgent multi-agent system, optimized for:
+- Rapid cancer type classification and routing
+- Clinical entity extraction (symptoms, staging, biomarkers)
+- First-pass treatment recommendations based on NCCN/ESMO guidelines
+

+
+## Dataset
+
+Trained on [MaximoLopezChenlo/OncoAgent-Clinical-266K](https://huggingface.co/datasets/MaximoLopezChenlo/OncoAgent-Clinical-266K), a curated oncology dataset combining:
+
+- **PMC-Patients** — Real clinical case presentations
+- **PubMedQA** — Evidence-based medical Q&A
+- **OncoCoT** — Chain-of-thought oncology reasoning (synthetic)
+- **NCCN/ESMO Guidelines** — Structured guideline extracts
+
+## Usage
+
+```python
+from peft import PeftModel
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+# Load base model
+base_model = AutoModelForCausalLM.from_pretrained(
+    "Qwen/Qwen3.5-9B",
+    device_map="auto",
+    torch_dtype="bfloat16",
+)
+tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen3.5-9B")
+
+# Load LoRA adapter
+model = PeftModel.from_pretrained(
+    base_model,
+    "MaximoLopezChenlo/OncoAgent-v1.0-9B",
+)
+
+# Inference
+messages = [
+    {"role": "system", "content": "You are a clinical oncology specialist."},
+    {"role": "user", "content": "55yo female, Grade 1 endometrioid adenocarcinoma..."},
+]
+inputs = tokenizer.apply_chat_template(messages, return_tensors="pt")
+outputs = model.generate(inputs, max_new_tokens=1024)
+print(tokenizer.decode(outputs[0], skip_special_tokens=True))
+```
+
+## vLLM Deployment (AMD MI300X)
+
+```bash
+# Serve with vLLM on ROCm
+python -m vllm.entrypoints.openai.api_server \
+    --model Qwen/Qwen3.5-9B \
+    --enable-lora \
+    --lora-modules oncoagent=MaximoLopezChenlo/OncoAgent-v1.0-9B \
+    --dtype bfloat16 \
+    --tensor-parallel-size 1 \
+    --gpu-memory-utilization 0.45
+```
+
+## Architecture
+
+OncoAgent v1.0 9B serves as the **Tier 1** model in a dual-tier architecture:
+
+```
+Clinical Case → Router → [Tier 1: 9B] → Specialist → Critic → Output
+                    ↓
+              (Complex cases)
+                    ↓
+              [Tier 2: 27B] → Specialist → Critic → Output
+```
