-- **Base Model:** [granite-34b-code-instruct-8k](https://huggingface.co/ibm-granite/granite-34b-code-instruct-8k)
-- **Quantization:** FP8 (E4M3 format)
-- **Quantization Method:** llmcompressor oneshot with FP8 scheme
-- **Calibration Dataset:** open_platypus (512 samples)
-- **Quantization Time:** 31.0 minutes
+## 🎯 Recommended Usage: vLLM (Required)
 
-## Usage
+For 34B models, **vLLM is essential** for practical deployment. FP8 quantization makes this flagship model accessible on high-end consumer GPUs.
+
+### Quick Start with vLLM
+
+```bash
+pip install vllm
+```
+
+**Python API:**
+
+```python
+from vllm import LLM, SamplingParams
+
+# vLLM auto-detects FP8 from model config
+llm = LLM(model="TevunahAi/granite-34b-code-instruct-8k-FP8", dtype="auto")
+
+# Generate
+prompt = "Write a Python function to calculate fibonacci numbers:"
+sampling_params = SamplingParams(temperature=0.7, max_tokens=256)
+
+outputs = llm.generate([prompt], sampling_params)
+for output in outputs:
+    print(output.outputs[0].text)
+```
+
+**OpenAI-Compatible API Server:**
+
+```bash
+vllm serve TevunahAi/granite-34b-code-instruct-8k-FP8 \
+    --dtype auto \
+    --max-model-len 8192
+```
+
+Then use with OpenAI client:
+
+```python
+from openai import OpenAI
+
+client = OpenAI(
+    base_url="http://localhost:8000/v1",
+    api_key="token-abc123",  # dummy key
+)
+
+response = client.chat.completions.create(
+    model="TevunahAi/granite-34b-code-instruct-8k-FP8",
+    messages=[
+        {"role": "user", "content": "Write a Python function to calculate fibonacci numbers"}
+    ],
+    temperature=0.7,
+    max_tokens=256,
+)
+
+print(response.choices[0].message.content)
+```
+
+### vLLM Benefits
+
+- ✅ **Weights, activations, and KV cache in FP8**
+- ✅ **~34GB VRAM** (50% reduction vs BF16's ~68GB)
+- ✅ **Single high-end GPU deployment** (H100, RTX 6000 Ada, A100 80GB)
+- ✅ **Native FP8 tensor core acceleration**
+- ✅ **Production-grade performance**
+
+## ⚠️ Transformers: Not Practical
+
+At 34B parameters, transformers will decompress to **~68GB+ VRAM**, requiring multi-GPU setups or data center GPUs. **This is not recommended for deployment.**
+

-### With Transformers
 ```python
 from transformers import AutoModelForCausalLM, AutoTokenizer
 import torch
 
+# Requires multi-GPU or 80GB+ single GPU
 model = AutoModelForCausalLM.from_pretrained(
     "TevunahAi/granite-34b-code-instruct-8k-FP8",
-    torch_dtype=torch.bfloat16,
-    device_map="auto",
+    device_map="auto",  # Will distribute across GPUs
+    torch_dtype="auto",
     low_cpu_mem_usage=True,
 )
-
 tokenizer = AutoTokenizer.from_pretrained("TevunahAi/granite-34b-code-instruct-8k-FP8")
 
 # Generate
 prompt = "Write a Python function to calculate fibonacci numbers:"
 inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
+
 outputs = model.generate(**inputs, max_new_tokens=256)
 print(tokenizer.decode(outputs[0], skip_special_tokens=True))
 ```
 
-### With vLLM (Recommended for production)
-```python
-from vllm import LLM, SamplingParams
+**Requirements:**
+```bash
+pip install torch>=2.1.0 transformers>=4.40.0 accelerate compressed-tensors
+```
 
-llm = LLM(model="TevunahAi/granite-34b-code-instruct-8k-FP8")
-sampling_params = SamplingParams(temperature=0.7, max_tokens=256)
+**System Requirements:**
+- **~68GB+ VRAM** (decompressed to BF16)
+- Multi-GPU setup or A100 80GB / H100 80GB
+- Not practical for most deployments
 
-prompts = ["Write a Python function to calculate fibonacci numbers:"]
-outputs = llm.generate(prompts, sampling_params)
-```
+**⚠️ Critical:** Use vLLM instead. Transformers is only viable for research/testing with multi-GPU setups.

+
+## 🔧 Why FP8 for 34B Models?
+
+### With vLLM/TensorRT-LLM:
+- ✅ **Enables single-GPU deployment** (~34GB vs ~68GB BF16)
+- ✅ **50% memory reduction** across weights, activations, and KV cache
+- ✅ **Faster inference** via native FP8 tensor cores
+- ✅ **Makes flagship model accessible** on high-end consumer/prosumer GPUs
+- ✅ **Minimal quality loss** for code generation tasks
+
+### Without FP8:
+- ❌ BF16 requires ~68GB VRAM (H100 80GB or multi-GPU)
+- ❌ Limited deployment options
+- ❌ Higher infrastructure costs
+
+**FP8 quantization transforms 34B from "data center only" to "high-end workstation deployable".**
