+### Quick Start with vLLM
+
+```bash
+pip install vllm
+```
+
+**Python API:**
+
+```python
+from vllm import LLM, SamplingParams
+from transformers import AutoTokenizer
+
+# vLLM auto-detects FP8 from model config
+llm = LLM(model="TevunahAi/NextCoder-14B-FP8", dtype="auto")
+
+# Prepare prompt with chat template
+tokenizer = AutoTokenizer.from_pretrained("TevunahAi/NextCoder-14B-FP8")
+messages = [{"role": "user", "content": "Write a Python function to calculate fibonacci numbers"}]
+prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
+
+# Generate
+outputs = llm.generate(prompt, SamplingParams(temperature=0.7, max_tokens=512))
+print(outputs[0].outputs[0].text)
+```
+
+**OpenAI-Compatible API Server:**
+
+```bash
+vllm serve TevunahAi/NextCoder-14B-FP8 \
+    --dtype auto \
+    --max-model-len 4096
+```
+
+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/NextCoder-14B-FP8",
+    messages=[
+        {"role": "user", "content": "Write a Python function to calculate fibonacci numbers"}
+    ],
+    temperature=0.7,
+    max_tokens=512,
+)
+
+print(response.choices[0].message.content)
+```

-Quantized on professional hardware to ensure quality and reliability:
-- **CPUs:** Dual Intel Xeon Max 9480 (224 threads, 128GB HBM2e)
-- **GPU:** NVIDIA RTX 5000 Ada Generation (32GB VRAM) with native FP8 support

-- **Software:** Ubuntu 25.10 | Python 3.12 | PyTorch 2.8 | CUDA 13 | llm-compressor 
+This model can be loaded with `transformers`, but **will decompress FP8 → BF16 during inference**, requiring ~28GB+ VRAM. For 14B models, **vLLM is strongly recommended** for practical single-GPU deployment.

-### Requirements
+**Requirements:**

-pip install torch>=2.1.0  # FP8 support requires PyTorch 2.1+
-pip install transformers>=4.40.0
-pip install accelerate
+pip install torch>=2.1.0 transformers>=4.40.0 accelerate compressed-tensors
 ```
 
 **System Requirements:**
-- PyTorch 2.1 or newer with CUDA support
-- NVIDIA GPU with FP8 support (Ada Lovelace or newer: RTX 40xx series, RTX 5000 Ada, H100, etc.)
+- **~28GB+ VRAM** (decompressed to BF16) - requires multi-GPU or high-end single GPU
 - CUDA 11.8 or newer
-- ~28GB VRAM for inference (or use multi-GPU with device_map="auto")
+- PyTorch 2.1+ with CUDA support
+
+**⚠️ Warning:** Most consumer GPUs will struggle with transformers inference at this size. Use vLLM for practical deployment.

+
+## 🔧 Why FP8?
+
+### With vLLM/TensorRT-LLM:

+- ✅ **Faster inference** via native FP8 tensor cores
+- ✅ **Single GPU deployment** on 24GB+ cards

+- ✅ **Minimal quality loss** (sub-1% perplexity increase)
+
+### With Transformers:
+- ✅ **Smaller download size** (~14GB vs ~28GB BF16)
+- ✅ **Compatible** with standard transformers workflow
+- ⚠️ **Decompresses to BF16** during inference (no runtime memory benefit)
+- ❌ **Requires 28GB+ VRAM** - impractical for most setups
+
+**For 14B models, vLLM is essential for practical deployment.**
