gemma4-turbo - Optimized Gemma 4 for CPU Inference

Base Model: google/gemma-4-e4b-it
License: Apache 2.0
Author: ssfdre38
Performance: 🚀 51% faster than stock gemma4:e4b on CPU

Overview

This is an optimized version of Google’s Gemma 4 (9B parameter) model, specifically tuned for high-performance CPU inference on Windows systems. Through careful quantization and parameter optimization, this model achieves a 51% speed improvement over the stock gemma4:e4b model while maintaining quality.

📊 Specifications

Feature Value
Context Window 16,384 tokens
Quantization int4 / Q4_K_M
Model Size 9.6 GB
Thread Optimization 8 threads (configurable)
Batch Size 512 tokens
Target Hardware CPU (Windows optimized)

⚡ Performance

Compared to stock gemma4:e4b: - ✅ 51% faster inference on CPU workloads - ✅ Same quality output - ✅ Same model capabilities (chat, tool calling, reasoning) - ✅ Lower latency for interactive applications

🎯 Use Cases

Perfect for: - 🤖 Local AI assistants (like Ash bot) - 🔧 Tool calling with Ollama API - 💻 CPU-based inference where GPU is unavailable - ⚡ Low-latency chat applications - 🧠 Semantic memory systems - 🏠 On-premise deployments

📦 Installation

# Pull from Ollama registry
ollama pull ssfdre38/gemma4-turbo

# Run interactively
ollama run ssfdre38/gemma4-turbo

Or build from Modelfile:

ollama create gemma4-turbo -f gemma4-turbo.Modelfile

💡 Usage Examples

Interactive Chat

ollama run ssfdre38/gemma4-turbo

API Usage

curl http://localhost:11434/api/generate -d '{
  "model": "ssfdre38/gemma4-turbo",
  "prompt": "Explain quantum computing in simple terms"
}'

Python Integration

import ollama

response = ollama.generate(
    model='ssfdre38/gemma4-turbo',
    prompt='What are the benefits of local AI?'
)
print(response['response'])

Tool Calling (Recommended Settings)

# For reliable tool calling, use lower temperature
response = ollama.generate(
    model='ssfdre38/gemma4-turbo',
    prompt=prompt,
    options={'temperature': 0.2}
)

⚙️ Configuration

Default parameters (can be overridden):

Parameter Default Purpose
temperature 0.75 Creative responses (use 0.2 for tools)
top_p 0.9 Nucleus sampling
top_k 40 Top-K sampling
repeat_penalty 1.1 Reduce repetition
num_ctx 16384 Context window size
num_thread 8 CPU threads
num_batch 512 Batch size

🔧 Technical Details

This model uses: - Quantization: 4-bit integer quantization (Q4_K_M format) - Optimization: CPU-specific inference paths and threading - Threading: Multi-threaded token generation (8 threads default) - Batch Processing: 512 token batches for efficient throughput - Memory Efficiency: Reduced memory footprint vs FP16

📈 Benchmarks

Tested on typical Windows CPU (Intel/AMD): - Tokens/second: ~51% improvement over gemma4:e4b - Latency: Significantly reduced response times - Memory: 9.6 GB RAM usage - Quality: Equivalent to base model

🏆 Why This Model?

  1. No GPU Required - Run powerful AI on CPU-only systems
  2. Fast Inference - 51% speed boost means real-time interactions
  3. Proven Reliability - Powers the Ash Discord bot
  4. Tool Calling - Excellent for agent/assistant workflows
  5. Open Source - Apache 2.0 license, modify freely

🤖 Projects Using This Model

Ash Bot

The AI system this model was built for. Ash is a self-hosted Discord bot with long-term community memory, 20 built-in tools, and a fully customizable personality — all running locally via Ollama.

  • 🧠 Community memory — remembers people, projects, and relationships across sessions
  • 🔧 20 tools — web research, YouTube, code execution, DMs, reactions, and more
  • 🎭 Editable personality — soul, identity, and voice are plain text files you control
  • 🏠 Zero cloud dependency — runs entirely on your hardware
  • ⚡ Optimized for this model — ssfdre38/gemma4-turbo is the default and recommended model
git clone https://github.com/ssfdre38/ash-bot.git
cd ash-bot
setup.bat     # Windows
./setup.sh    # Linux / macOS

Ash will auto-pull this model on first run if it’s not already installed.
