Open WebUI — system requirements

No RAM/CPU figure published anywhere in the README or docs repo (independently re-checked). Three first-class install paths exist as separate image tags — ghcr.io/open-webui/open-webui:main (CPU-only, no bundled LLM runtime), :ollama (bundles Ollama, GPU or CPU), :cuda (GPU-accelerated) — actual footprint depends entirely on which local models are loaded, which the project doesn't specify a baseline for. This entry documents the :main image. Do not harvest the docs performance page's illustrative `memory: 8G / cpus: 4.0` compose-limits snippet as a figure — it is a commented "adjust based on usage" example, not a spec.
