Validate activity before betting a new project on chatgpt-plugin-eval. - Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers. - 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. ## When NOT to use open-webui - When looking for tooling that exclusively supports APIs other than Ollama and OpenAI, as these are specific areas of focus for open-webui. - If the requirement is a highly specialized interface tailored to specific tasks rather than a general AI interaction platform. ## Common questions ### What is the difference between chatgpt-plugin-eval and open-webui? chatgpt-plugin-eval: LLM Platform Security: Applying a Systematic Evaluation Framework to OpenAI's ChatGPT Plugins. open-webui: User-friendly AI Interface (Supports Ollama, OpenAI API, ...).
