Deep Dive Into The Technical Architecture
Let’s understand the technical architecture of both the tools precisely.
Ollama Architecture

Data Flow Examples
1. You send a request
User sent a request in the first place.
2. Rest API receives it
- Validates the JSON format
- Checks if the model name is valid
- Passes request to Model Manager
3. Model Manager Processes
// Simplified Go code inside Ollama
func (m *ModelManager) HandleRequest(req *GenerateRequest) {
model := m.LoadModel(req.ModelName) // Load from File System
if model == nil {
return error("Model not found")
}
return m.inference.Generate(model, req.Prompt) // Send to Inference Engine
}
4. File System Interaction
- Model Manager asks, “Do I have Llama 3.2 loaded in memory?”
- If not: “Load model files from ~/.ollama/models/blobs/…”
- Reads gigabytes of model weights into RAM
5. Inference Engine Works
// Simplified C++ inference process
std::string generate_response (const Model& model, const std::string& prompt) {
auto tokens = tokenize(prompt); // Convert text to numbers
auto output = model.forward(tokens); // AI magic happens here
return detokenize(output); // Convert back to text
}
6. GPU Layers Accelerate
- Mathematical operations get offloaded to the GPU.
- Instead of the CPU doing 1 calculation at a time.
- A GPU does thousands simultaneously.
7. Response Flows Back
Now the response flows back from
Inference Engine → Model Manager → REST API → Your application
LM Studio Architecture

User Flow Example
Step 1: Click “Download Model”
User Interface (GUI)
↓ “Download Llama 3.2”
Python Backend
↓ Downloads model files
Model Registry
↓ Stores in ~/LMStudio/models/
Step 2: Select Model For Chatting
User Interface
↓ “Use Llama 3.2 for chat”
Python Backend
↓ model = load_model(“llama-3.2”)
Inference Engine
↓ Loads into memory
GPU Managers
↓ Allocates GPU memory
Step 3: Type A Message
// What happens in the Electron GUI (React code)
function sendMessage() {
const userMessage = document.getElementById('chat-input').value;
// Send to Python backend
fetch('http://localhost:1234/v1/chat/completions', {
method: 'POST',
headers: {'Content-Type': 'application/json'},
body: JSON.stringify({
model: 'current-model',
messages: [{role: 'user', content: userMessage}]
})
})
.then(response => response.json())
.then(data => {
// Display AI response in GUI
displayMessage(data.choices[0].message.content);
});
}
Step 4: Python Backend Process
# Simplified backend processing
@app.post("/v1/chat/completions")
async def chat_completion(request: ChatRequest):
# Get current model from Model Registry
model = get_loaded_model()
# Prepare conversation context
conversation = build_conversation_context(request.messages)
# Send to Inference Engine
response = await model.generate(
conversation,
max_tokens=request.max_tokens,
temperature=request.temperature
)
# Return formatted response
return {
"choices": [{"message": {"content": response}}]
}
