- You need to run AI at scale without per-token costs \u2014 generating thousands of reports, processing large datasets<\/li>\n
- You want to fine-tune a model on your specific codebase or domain<\/li>\n
- You need offline capability \u2014 field operations, secure environments<\/li>\n
- DPDP Act compliance requires data to stay in India on your infrastructure<\/li>\n<\/ul>\n
Use commercial (Claude\/ChatGPT) when:<\/strong><\/p>\n\n- You need the absolute best quality for complex reasoning tasks<\/li>\n
- You’re doing low-volume, high-value tasks where quality matters more than cost<\/li>\n
- You don’t have GPU hardware and don’t want to invest in it<\/li>\n
- You need the largest context windows<\/li>\n<\/ul>\n
Getting Started \u2014 Ollama<\/h2>\nOllama is the easiest way to run open source LLMs locally. It works on Mac, Linux, and Windows.<\/p>\n # Install Ollama\r\ncurl -fsSL https:\/\/ollama.com\/install.sh | sh\r\n\r\n# Pull and run a model\r\nollama run llama3.3\r\n\r\n# Run smaller model (works on CPU, no GPU needed)\r\nollama run phi4\r\n\r\n# Run code-specific model\r\nollama run qwen2.5-coder:7b\r\n\r\n# List available models\r\nollama list\r\n\r\n# Ollama exposes a local API on port 11434\r\ncurl http:\/\/localhost:11434\/api\/generate -d '{\r\n \"model\": \"llama3.3\",\r\n \"prompt\": \"Explain what a closure is in JavaScript\"\r\n}'<\/code><\/pre>\nHardware Requirements<\/h2>\n\n\n\n| Model Size<\/th>\n | Minimum RAM<\/th>\n | Recommended<\/th>\n | GPU?<\/th>\n<\/tr>\n<\/thead>\n | \n\n| 3B\u20137B models (Phi-4, Gemma)<\/td>\n | 8GB RAM<\/td>\n | 16GB RAM<\/td>\n | Optional (CPU works)<\/td>\n<\/tr>\n | \n| 13B\u201314B models<\/td>\n | 16GB RAM<\/td>\n | 32GB RAM<\/td>\n | Recommended<\/td>\n<\/tr>\n | \n| 30B\u201334B models<\/td>\n | 32GB RAM<\/td>\n | 64GB RAM + GPU<\/td>\n | Required for speed<\/td>\n<\/tr>\n | \n| 70B models (Llama 3.3)<\/td>\n | 64GB RAM<\/td>\n | 80GB VRAM (A100)<\/td>\n | Required<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n For most developers: a MacBook Pro with M3 chip and 32GB RAM runs 7B\u201314B models excellently.
