Most people think AI = ChatGPT. But for high-security industries like Finance or Healthcare, sending data to a Cloud API is a huge “No.” To solve this, you need to shift from Cloud LLMs to Local LLMs. Here is how you Decode the “No Internet” problem: 1️⃣ Pick an Open-Source Model: Instead of OpenAI, use models like Llama 3 (Meta), Mistral, or Gemma (Google). These are weights you can actually download and own. 2️⃣ Quantization is Key: A massive model won’t fit on standard office servers. Use Quantization (4-bit or 8-bit) to compress the model so it runs fast on local hardware without losing much “intelligence.” 3️⃣ Local Serving Tools: Use frameworks like Ollama, vLLM, or LocalAI. These tools create a local API that works exactly like ChatGPT but stays 100% inside the company’s firewall. 4️⃣ Offline Vector Database: For the RAG pipeline, use local databases like ChromaDB or FAISS. This ensures that even the “search” part of your AI never hits the public web. Privacy isn’t a feature; it’s a requirement. 🛠️ Follow Lets Decode AI to learn how to build AI that works anywhere, even in a bunker. #AI #Privacy #DataSecurity #LocalLLM #Llama3 Ollama SoftwareEngineering GenerativeAI LetsDecodeAI TechCareer 0:14
