@chiragardeshna

Hi there, I am a strong fit for this project because I have deployed open-source LLMs in fully self-hosted environments without reliance on external APIs. I have implemented Hugging Face transformer models such as LLaMA and Mistral variants, built FastAPI-based inference servers, optimized GPU deployments, and delivered secure web-based chat interfaces. I would recommend starting with a quantized Mistral or LLaMA 2/3 7B–8B model for balanced performance, deployed via vLLM or Text Generation Inference, with a FastAPI backend and a lightweight React or HTMX-based chat UI. For production use, I recommend a server with at least 32–64 GB RAM and an NVIDIA GPU with 16–24 GB VRAM (e.g., RTX 4090 or A5000 equivalent) for smooth inference; CPU-only fallback is possible but slower. I am ready to share relevant LLM deployment examples and outline a secure, optimized architecture tailored to your server environment. Regards Chirag

@webmasters486

Hi there, I can build a fully self hosted ChatGPT style chatbot using an open source LLM such as LLaMA or Mistral, deployed directly on your VPS or dedicated server without relying on any external APIs. The backend can be developed in Python using FastAPI with Transformers from Hugging Face, ensuring clean architecture, secure endpoints, and optimized inference. For performance and quality balance, I recommend Mistral 7B or LLaMA 2 7B with quantization. Minimum specs would be 32GB RAM and a GPU with at least 16GB VRAM such as NVIDIA A4000. For smoother inference and future fine tuning, 24GB VRAM is ideal. CPU only deployment is possible but not recommended for real time chat. I can also implement custom dataset fine tuning or instruction tuning using LoRA, plus build a responsive web based chat UI with authentication and rate limiting. I have previously worked on private LLM deployments, retrieval augmented systems, and automation driven AI agents. Happy to share architecture details and discuss the best stack for your budget.
