ChatGPT (GPT-5.6 Sol) and Llama (Meta's Llama 4 Maverick) represent two fundamentally different approaches to AI. ChatGPT is a polished cloud platform with built-in tools, plugins, and a subscription model. Llama is an open-source model you can download, run locally, and fine-tune without paying per-token API fees.
The prompting strategies that maximize results differ significantly between these two. ChatGPT benefits from its rich ecosystem and system instructions. Llama benefits from clear, direct prompts and can be customized at the model level through fine-tuning. Here's how to get the best from each.
