Granite-34B-Code-Instruct-8k-2048-Calibration-FP8

Premium FP8 quantization with 2,048 code-optimized calibration samples

This is a premium FP8 quantized version of ibm-granite/granite-34b-code-instruct-8k featuring rigorous code-optimized multi-dataset calibration for production-grade reliability. Quantized by TevunahAi on enterprise-grade hardware.

🎯 Recommended Usage: vLLM (Required)

For 34B models, vLLM is essential for practical deployment. Premium FP8 quantization makes this flagship code model accessible on high-end consumer GPUs.

Quick Start with vLLM

pip install vllm

Python API:

from vllm import LLM, SamplingParams

# vLLM auto-detects FP8 from model config
llm = LLM(model="TevunahAi/Granite-34B-Code-Instruct-8k-2048-Calibration-FP8", dtype="auto")

# Generate code
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:

vllm serve TevunahAi/Granite-34B-Code-Instruct-8k-2048-Calibration-FP8 \
    --dtype auto \
    --max-model-len 8192

Then use with OpenAI client:

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-2048-Calibration-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, A100 80GB, RTX 6000 Ada)
• ✅ Native FP8 tensor core acceleration
• ✅ Premium 2048-sample code-optimized calibration
• ✅ Flagship code generation quality

⚠️ 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.

<details> <summary>Transformers Example (Multi-GPU Required - Click to expand)</summary>

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

# Requires multi-GPU or 80GB+ single GPU
model = AutoModelForCausalLM.from_pretrained(
    "TevunahAi/Granite-34B-Code-Instruct-8k-2048-Calibration-FP8",
    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-2048-Calibration-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))

Requirements:

pip install torch>=2.1.0 transformers>=4.40.0 accelerate compressed-tensors

System Requirements:

• ~68GB+ VRAM (decompressed to BF16)
• Multi-GPU setup or A100 80GB / H100 80GB
• Not practical for most deployments

⚠️ Critical: Use vLLM instead. Transformers is only viable for research/testing with multi-GPU setups.

📊 Model Details

🏆 Premium Code-Optimized Calibration

This model was quantized using TevunahAi's premium code-focused calibration process:

Calibration Details

• Total Samples: 2,048 (4-8x industry standard)
• Datasets Used: 4 diverse sources
• Coverage: Comprehensive across coding and reasoning tasks

Why Premium Calibration for Code Models?

Most FP8 quantizations use 256-512 samples from generic datasets. TevunahAi uses 2,048 samples across 4 diverse datasets, ensuring:

• ✅ Superior code generation quality across languages
• ✅ Better handling of complex programming patterns
• ✅ Robust STEM reasoning (math, logic, algorithms)
• ✅ Consistent performance on edge cases
• ✅ Production-grade reliability for enterprise code generation
• ✅ Quality retention: ~97-98% vs ~95-96% for standard quantization

When deploying flagship code models, premium calibration is essential.

🔧 Why FP8 for 34B Code 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 prosumer GPUs
• ✅ Premium calibration maintains code quality

Without FP8:

• ❌ BF16 requires ~68GB VRAM (A100 80GB or multi-GPU)
• ❌ Limited deployment options
• ❌ Higher infrastructure costs

FP8 quantization transforms 34B from "data center only" to "high-end workstation deployable".
