 - Performance on highly specialized technical domains may vary
 - Very long contexts (150K+ tokens) may require substantial VRAM
+- Image understanding works best with clear, well-lit images
 - The model is primarily optimized for English, with varying performance on other languages
+- Function calling requires well-structured prompts and tool definitions
 - Not suitable for real-time applications requiring sub-second latency without optimization
+- Vision capabilities are optimized for static images, not video
+- Tool execution requires external implementation of actual tool functions
