🧮 How the Intelligence Works

5-Factor Scoring Algorithm

The intelligent selector uses a sophisticated mathematical model with weighted factors:

Hardware Tier Classification

• EXTREME (64+ GB RAM, 16+ cores) - Can run 70B+ models
• VERY HIGH (32-64 GB RAM, 12+ cores) - Optimal for 13B-30B models
• HIGH (16-32 GB RAM, 8-12 cores) - Perfect for 7B-13B models
• MEDIUM (8-16 GB RAM, 4-8 cores) - Suitable for 3B-7B models
• LOW (4-8 GB RAM, 2-4 cores) - Limited to 1B-3B models

Apple Silicon Optimization

Special handling for Apple Silicon with unified memory:

• Dynamic VRAM calculation based on total system memory
• Architecture performance boost (+15% multiplier)
• Thermal efficiency consideration for sustained performance
