Validate activity before betting a new project on femtoGPT. - Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic. - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. - Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge. ## Common questions ### What is the difference between litellm and femtoGPT? litellm: Python SDK and Proxy Server for calling multiple LLM APIs. femtoGPT: Pure Rust implementation of a minimal Generative Pretrained Transformer.
