+        ### Actual Performance (Updated {get_current_time()})
         
-        1. **Use Fast Mode** - Mistral 7B generates in 5-15 seconds
-        2. **Enable Turbo Mode** - Reduces tokens and processing time
-        3. **Smaller Images** - Upload images under 1MB for faster analysis
-        4. **Simple Designs** - Complex layouts take longer
+        | Mode | Model | Real Speed | Quality |
+        |------|-------|------------|---------|
+        | **Ultra Fast** | Mistral-7B | ⚡ 5-10s | ★★★★ |
+        | **Fast** | Llama-8B | ⚡ 8-15s | ★★★★ |
+        | **Balanced** | Mixtral-8x7B | ⚡ 15-25s | ★★★★★ |
+        | **Quality** | Llama-70B | 30-45s | ★★★★★ |
