⚡ Quick Start

🔧 Setup (run once)

!pip install -q huggingface_hub

import os
import site
from huggingface_hub import hf_hub_download

# --- CONFIGURATION ---
repo_id = "IamPradeep/Bonsai-27B-GGUF-Colab-Prebuilt-GPU"

# ------------------------------------------------------------------------------
# 1. Download + extract the pre-compiled binary package
# ------------------------------------------------------------------------------
print("1. Downloading pre-compiled binary package...")
bin_zip_path = hf_hub_download(repo_id=repo_id, filename="llama_bin.tar.gz")

# Extract the binaries into a folder called 'llama_bin'
!mkdir -p ./llama_bin
!tar -xzvf {bin_zip_path} -C ./llama_bin

# Grant executable permissions to the binary
!chmod +x ./llama_bin/llama-cli

# ------------------------------------------------------------------------------
# 1b. Install the CUDA 12 runtime libraries required by the pre-built binary
# ------------------------------------------------------------------------------
print("📥 Installing CUDA 12 runtime libraries...")
!pip install -q nvidia-cuda-runtime-cu12 nvidia-cublas-cu12 nvidia-cuda-nvrtc-cu12

# ------------------------------------------------------------------------------
# 2. Download model
# ------------------------------------------------------------------------------
print("\n2. Downloading model (this takes <=1 minute for 3.8 GB)...")
model_path = hf_hub_download(repo_id=repo_id, filename="Bonsai-27B-Q1_0.gguf")

# ------------------------------------------------------------------------------
# 3. Environment setup — put the extracted dir AND the pip‑installed CUDA
#    libraries on LD_LIBRARY_PATH so the loader can find libcudart.so.12.
# ------------------------------------------------------------------------------
nvidia_lib_dirs = []
for pkg in ("cuda_runtime", "cublas", "cuda_nvrtc"):
    pkg_path = os.path.join(site.getsitepackages()[0], "nvidia", pkg, "lib")
    if os.path.isdir(pkg_path):
        nvidia_lib_dirs.append(pkg_path)

existing = os.environ.get("LD_LIBRARY_PATH", "")
parts = ["./llama_bin"] + nvidia_lib_dirs
if existing:
    parts.append(existing)
os.environ["LD_LIBRARY_PATH"] = ":".join(parts)

🤖 Text Inference

# Run the text model!
system_prompt = "You are a helpful AI assistant."
prompt = "Explain quantum computing in simple terms."

print(f"\n--- Running text inference with Bonsai-27B-GGUF ---\n")

!./llama_bin/llama-cli \
  -m "{model_path}" \
  -ngl 99 \
  -sys "{system_prompt}" \
  -p "{prompt}" \

👁️ Vision / Multimodal Inference (Live Upload)

You can also run vision tasks by downloading the vision projector (mmproj) and uploading an image directly inside Google Colab:

from PIL import Image
from google.colab import files

# 1. Download Vision Projector
print("Downloading Vision Projector (~629 MB)...")
mmproj_path = hf_hub_download(repo_id=repo_id, filename="Bonsai-27B-mmproj-Q8_0.gguf")

# 2. Live Image Upload
print("\n" + "="*50)
print("📸 PLEASE UPLOAD AN IMAGE FROM YOUR DEVICE:")
print("="*50)

uploaded = files.upload()

if not uploaded:
    print("\n❌ No file was uploaded!")
else:
    # Save the uploaded file path
    image_filename = list(uploaded.keys())[0]
    image_path = f"./{image_filename}"
    
    print(f"\n✅ Uploaded successfully: {image_filename}")
    display(Image.open(image_path))

    # 3. Run Multimodal Inference
    system_prompt = "You are an expert AI vision assistant. Provide clear, detailed, and accurate descriptions of images."
    prompt = "Describe what you see in this image in detail."

    print(f"\n🤖 Running Vision Inference on {image_filename}...\n")

    !./llama_bin/llama-cli \
      -m "{model_path}" \
      --mmproj "{mmproj_path}" \
      --image "{image_path}" \
      -sys "{system_prompt}" \
      -p "{prompt}" \
      -ngl 99 \
      --temp 0.2 \
      -n 2048 \
      --reasoning off     # Use "on" to enable reasoning/thinking

💡 Notes

• Model Download Speed: The default Bonsai-27B-Q1_0.gguf file is ~3.8 GB. Downloading it inside Colab typically takes < 1 minute depending on network throughput.
• Other Variants Available: This repository hosts alternative quantizations and vision projector files:
• Language Models: Bonsai-27B-F16.gguf (53.8 GB), Bonsai-27B-dspark-bf16.gguf (7.29 GB), and Bonsai-27B-dspark-Q4_1.gguf (1.79 GB)
• Vision Projectors (mmproj): Bonsai-27B-mmproj-BF16.gguf (931 MB) and Bonsai-27B-mmproj-Q8_0.gguf (629 MB)

Simply adjust the filename parameter in hf_hub_download to load your preferred variant.

• Architecture: Uses 1-bit quantization, delivering high reasoning capability while keeping GPU VRAM requirements to a minimum.
