Use cases

• Generate short code snippets in Python and other languages
• Answer reasoning questions with step-by-step explanations
• Run as a lightweight fallback model on edge devices

Pros

• Competitive performance relative to much larger models on code and math tasks
• Small size enables fast inference on CPUs and low-vRAM GPUs
• Open-source weights allow full customization and offline use

Cons

• Limited context window (2048 tokens) restricts handling of long prompts
• Outperformed by specialized code models like CodeLlama on complex programming tasks
• Not suitable for general chat or diverse open-domain dialogue
