Validate activity before betting a new project on sarathi-serve. - 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 LlamaFactory and sarathi-serve? LlamaFactory: Unified Efficient Fine-Tuning of 100+ LLMs & VLMs. sarathi-serve: A low-latency & high-throughput serving engine for LLMs. See the comparison table for live GitHub stats and shared categories. ### When should I choose LlamaFactory over sarathi-serve?
