📦 Model Loading Issues

Model Won’t Load

Problem: GGUF model fails to load or shows error.

Solutions:

  1. Check file format: Must be .gguf extension 
    ✅ model.gguf
❌ model.bin
❌ model.safetensors
  2. Check file integrity: Re-download if corrupted
    • Verify file size matches source
    • Check MD5/SHA256 hash if available
  3. Check RAM availability:
    • Model needs ~1.5x its file size in RAM
    • Close other applications
    • Try a smaller model
  4. Check file permissions:
    • Ensure read access to the model file
    • Try moving to a different directory

“Out of Memory” Error

Problem: System runs out of RAM when loading model.

Solutions:

  1. Use a smaller model: | Your RAM | Max Model Size | |———-|—————| | 4GB | ~2GB model | | 8GB | ~5GB model | | 16GB | ~12GB model |

  2. Use higher quantization:
    • Q2_K or Q3_K are smallest
    • Q4_K_M is good balance
  3. Reduce context length:
    • Lower from 4096 to 2048 or 1024
  4. Close other applications:
    • Browsers use significant RAM
    • Close unused programs

Model Loads But Doesn’t Respond

Problem: Model loads successfully but chat doesn’t work.

Solutions:

  1. Wait for full initialization: Some models take time after loading
  2. Check status bar: Ensure it shows “Ready”
  3. Try a simple prompt: Start with “Hello”
  4. Restart the application: Sometimes helps with initialization
  5. Try a different model: Model may be incompatible

Slow Model Loading

Problem: Model takes very long to load.

Solutions:

  1. Use SSD storage: Models load faster from SSD than HDD
  2. Enable GPU acceleration: Offload layers to GPU
  3. Use smaller models: Larger models take longer
  4. Check disk health: Slow disk can cause delays

💬 Chat Issues

No Response from AI

Problem: AI doesn’t respond to messages.

Solutions:

  1. Check model is loaded: Status bar should show model name
  2. Wait for processing: Check for “Processing…” indicator
  3. Try shorter prompts: Very long prompts may timeout
  4. Restart application: Clear any stuck states

Slow Responses

Problem: AI responses take too long.

Solutions:

  1. Enable GPU acceleration: 
    # For NVIDIA GPUs
pip uninstall llama-cpp-python
pip install llama-cpp-python --extra-index-url https://abetlen.github.io/llama-cpp-python/whl/cu121
  2. Reduce max tokens: Lower response length limit
  3. Use smaller model: Faster inference
  4. Increase CPU threads: In settings
  5. Close background apps: Free up resources

Repetitive or Low-Quality Responses

Problem: AI gives repetitive or poor quality answers.

Solutions:

  1. Adjust temperature: Try 0.7-0.9 for more variety
  2. Increase repeat penalty: Set to 1.1-1.2
  3. Use better model: Larger models give better responses
  4. Improve prompts: Be more specific and detailed
  5. Clear chat history: Start fresh conversation

Chat History Lost

Problem: Previous conversations disappear.

Solutions:

  1. Enable auto-save: In settings
  2. Export important chats: Use export feature
  3. Check storage location: Ensure write permissions
  4. Don’t clear cache: Avoid clearing app data

✨ Smart Floating Assistant Issues

Button Doesn’t Appear

Problem: The ✨ button doesn’t show when selecting text.

Solutions:

  1. Check model is loaded: Smart Floater needs a model
  2. Select more text: Minimum 5 characters required
  3. Check addon is enabled: Open addon panel to verify
  4. Wait a moment: Button appears after brief delay
  5. Try different application: Some apps block clipboard access

Button Appears But Nothing Happens

Problem: Clicking the button doesn’t open the menu.

Solutions:

  1. Check for popup blockers: Some security software blocks popups
  2. Try clicking again: May need a second click
  3. Check screen position: Popup may be off-screen
  4. Restart addon: Stop and start from addon panel

Processing Fails

Problem: Summarize or Comment action fails.

Solutions:

  1. Check model is loaded: Required for processing
  2. Try shorter text: Very long text may timeout
  3. Check error message: Provides specific guidance
  4. Restart application: Clear any stuck states

Clipboard Issues

Problem: Smart Floater interferes with clipboard.

Solutions:

  1. This is normal: Smart Floater temporarily uses clipboard
  2. Clipboard is restored: Original content is restored after
  3. If content lost: Undo (Ctrl+Z) in source application
  4. Disable if problematic: Turn off in addon settings

🔧 Performance Issues

High CPU Usage

Problem: GGUF Loader uses too much CPU.

Solutions:

  1. Reduce thread count: In settings
  2. Use GPU acceleration: Offload work to GPU
  3. Use smaller model: Less computation needed
  4. Lower context length: Reduces processing

High Memory Usage

Problem: Application uses too much RAM.

Solutions:

  1. Use smaller model: Primary memory consumer
  2. Use higher quantization: Q2, Q3, Q4 use less RAM
  3. Reduce context length: Lower memory footprint
  4. Restart periodically: Clears accumulated memory

Application Freezes

Problem: GGUF Loader becomes unresponsive.

Solutions:

  1. Wait for processing: Long operations may cause temporary freeze
  2. Check Task Manager: See if still processing
  3. Force close if needed: End task and restart
  4. Use smaller model: Reduces freeze likelihood
  5. Report bug: If happens consistently
