Integration Examples
🔧 Python Integration
import requests
import json
def query_koala(prompt, system_message="You are a helpful assistant."):
"""Query Koala 13B via Ollama API"""
url = "http://localhost:11434/api/generate"
payload = {
"model": "koala:13b",
"prompt": prompt,
"system": system_message,
"stream": False,
"options": {
"temperature": 0.7,
"top_p": 0.9
}
}
response = requests.post(url, json=payload)
return response.json()['response']
# Example usage
result = query_koala(
"Explain photosynthesis in simple terms",
"You are an educational tutor. Explain concepts clearly and provide examples."
)
print(result)🌐 Web Integration
// Node.js integration with Express
const express = require('express');
const { exec } = require('child_process');
const app = express();
app.use(express.json());
app.post('/api/chat', async (req, res) => {
try {
const { message, context } = req.body;
const command = `ollama run koala:13b "${message}"`;
exec(command, (error, stdout) => {
if (error) {
return res.status(500).json({ error: error.message });
}
res.json({
response: stdout.trim(),
model: 'koala-13b',
context: 'conversational'
});
});
} catch (error) {
res.status(500).json({ error: error.message });
}
});
app.listen(3000, () => {
console.log('Koala API server running on port 3000');

🤔 Frequently Asked Questions
How does Koala 13B differ from other conversational models?
Koala 13B was specifically fine-tuned on dialogue datasets with emphasis on clear communication and user accessibility. Unlike general-purpose models, it prioritizes conversational coherence and approachable language over complex reasoning capabilities.
What are the hardware requirements for running Koala 13B locally?
Minimum requirements include 16GB RAM, 10GB storage space, and a 6+ core CPU. GPU acceleration is optional but recommended with 8GB+ VRAM for optimal performance. The model runs efficiently on modern consumer hardware.
Is Koala 13B suitable for enterprise applications?
Yes, Koala 13B is suitable for customer-facing applications where clear communication and user experience are priorities. It's particularly effective for educational support, customer service, and content moderation scenarios where approachable responses are valued.
How does Koala 13B handle safety and content moderation?
The model incorporates constitutional AI training for safety compliance and includes built-in content filtering. However, deployment should include additional safety measures and human oversight for production applications, especially in educational or customer service contexts.
