Ollama Local LLM
Ollama is a CLI tool that downloads and runs open-source LLMs locally. Users can run Llama 2, Mistral, Phi, and others on personal hardware (MacBook M1, Linux GPU server). No API costs, full privacy, inference in <100ms on modern GPUs. Learning curve: 1-2 weeks for basics, 4-6 weeks for production optimization. Teams using local LLMs report 70% cost savings vs OpenAI API and 10-100x faster inference. Skill demand rising as enterprises move away from cloud LLM dependency.
什麼是 Ollama Local LLM
Ollama is a command-line tool for downloading and running open-source large language models on local hardware (laptops, servers). Users run ollama run mistral and interact with a 7B-parameter model via terminal. Ollama handles model download (GGML quantized format, 3-45GB depending on model size), memory management, and inference. It's a bridge between cloud APIs (OpenAI, Anthropic) and self-hosted inference frameworks (vLLM, TensorRT). Ollama trades some customization for ease, users get a working LLM in 2 minutes, not 2 days.
