MAITO’s local translation uses AI models stored on your computer. This guide shows you how to download, manage, and remove these models.
Understanding Models
What Are Translation Models?
Translation models are AI files that power MAITO’s local translation:
- File Format: ONNX (Open Neural Network Exchange)
- Size: 2-8GB per model
- Storage:
%APPDATA%\Pangaia Software\MAITO\Models - One-time Download: Download once, use forever offline
Available Model Families
Rosetta Models
- Optimized by Pangaia Software
- Trained specifically for translation
- 32 languages supported
- 2.5GB size
- Fastest inference speed
Accessing Model Management
Open Settings → Translation tab → Local AI Translation section
You’ll see five areas:
- Installed Models - Models already on your device
- Model Benchmarking - Test the performance of your models
- Storage Information - Disk space usage
- Available Models - Models available for you to download
- Local Translation Settings - Settings to tweak the inner workings of the local translation engine

Downloading Models
Viewing Available Models
The Available Models list shows:
- Model name
- Size
- Type (CPU/GPU optimized)
- Compatibility with your hardware
- Recommendation status (⭐ for recommended)
Rosetta models appear first in the list.
Download a Model
- Browse the Available Models list
- Find a model that interests you (Rosetta recommended)
- Click the Download button next to it
- Monitor download progress
- Wait for completion
Download Progress Shows:
- Percentage complete
- MB downloaded / Total MB
- Estimated time remaining
- Cancel button

Recommended Models
MAITO automatically recommends models with a ⭐ icon based on your hardware. These recommendations ensure optimal performance for your system.
Canceling Downloads
If you need to cancel:
- Click Cancel button during download
- Partial files are automatically cleaned up
- You can restart the download later
Setting Default Model
After downloading:
- Go to Installed Models section
- Find and select your newly downloaded model
- Click Set as Default
- This model will be used for all translations

Note that the selected model in the screenshot is a sample, you may have downloaden another variant.
Managing Downloaded Models
Viewing Available Models
The Available Models section shows:
- Model name
- File size
- Download date
- Status (Active/Inactive)
- Actions (Remove, Benchmark, Set as Default)
The currently active model is highlighted.
Switching Between Models
To switch which model MAITO uses:
- Click Set as Default on the desired model
- MAITO reinitializes with the new model (2-3 seconds)
- Next translation uses the new model
Model Comparison
Download multiple models and switch between them to find which provides the best balance of speed and quality for your needs!
Removing Models
To free up disk space:
- Locate model in Available Models
- Ensure it’s not the active model (switch to another first)
- Click Remove button
- Confirm deletion
- Model files are permanently deleted
You Cannot Remove:
- The currently active model
- Models that are downloading
Storage Information
The Storage Information section displays:
Three-Segment Breakdown:
- Models: Space used by all downloaded models
- Other: Cache, logs, temporary files
- Available: Free space remaining on drive
Visual Progress Bar:
- Blue: Models
- Gray: Other (non-MAITO) data on your disk
- Green: Available space

Low Disk Space
If available space drops below 2GB, you may encounter issues downloading new models or translating long texts. Consider removing unused models.
Model Recommendations
For CPU-Only Systems
Recommended: Rosetta 4B CPU
- Optimized for CPU inference
- Fast on modern processors
- Works on any x64 Windows system
- 2.5GB download
For GPU Systems
Recommended: Rosetta 4B DML
- DirectML GPU acceleration
- Faster than CPU version
- Requires compatible GPU
- 2.5GB download
For Low-End Systems
If your device assessment showed “Poor” or “Fair”:
Recommended: Rosetta 4B CPU
- Best performance on limited hardware
- Smallest memory footprint
- MAITO auto-adjusts context window
- Still works, just slower
Experiment Freely
Models don’t conflict with each other. Download several, test them all, keep your favorites, and remove the rest!
Troubleshooting
”Download Failed” Error
Solutions:
- Check internet connection
- Verify sufficient disk space (need 2x model size temporarily)
- Disable VPN temporarily
- Check firewall isn’t blocking MAITO
- Retry download (it resumes from where it left off)
“Cannot Remove Model” Error
Cause: Trying to remove the active model.
Solution:
- Download/activate a different model first
- Then remove the unwanted model
Model Downloaded But Won’t Load
Solutions:
- Check model appears in Installed Models
- Verify file size matches expected size (not truncated)
- Remove and re-download the model
- Check anti-virus didn’t quarantine files
- Ensure sufficient RAM available
Very Large “Other” Storage
Cause: Cached data, logs, temporary files accumulated.
Solutions:
- Settings → Advanced → Clear Cache
- Manually delete logs:
%APPDATA%\Pangaia Software\MAITO\logs - Restart MAITO
Best Practices
Download Strategy
- Start with Recommended: Download MAITO’s recommended model first
- Test Performance: Benchmark it (see Benchmark Guide)
- Try Alternatives: If unsatisfied, try other models
- Keep Favorites: Remove models you don’t use
Storage Management
- Monitor Space: Check storage info regularly
- Remove Unused: Don’t hoard models you never use
- Keep Active Models: Maintain 2-3 models for different use cases
- Plan for Updates: Models may be updated, need space for new versions
Model Selection
Prioritize:
- Speed: If translation speed matters most → Rosetta DML
- Compatibility: If CPU-only system → Rosetta CPU
- Experimentation: If curious → Download multiple, compare
- Quality: All Rosetta models have excellent quality
Advanced: Manual Model Installation
For advanced users, models can be manually placed:
Location: %APPDATA%\Pangaia Software\MAITO\Models
Structure:
Models/
├── Rosetta-4B-CPU-INT4/
│ ├── model.onnx
│ ├── model.onnx.data
│ └── config.json
└── Rosetta-4B-DML-INT4/
├── model.onnx
└── ...
After manual placement:
- Restart MAITO
- Model appears in Installed Models
- Set as default to use
Advanced Users Only
Manual model installation is not recommended for most users. Use the built-in download feature to ensure correct installation and configuration.
