I think I made the best general use System Prompt for Qwen 3.5 (OpenWebUI + Web search)

Qwen 3.5 is wildly good. Especially with good system prompt. This prompt will execute a web search, then think, then continue the search until it has enough information to give you a detailed answer. It prioritizes searching latest information when needed. I'm running this with 131K context but you should be able to get away with less. I do not use an embedding or re ranking model. I feed full context to the model. Be sure to enable Native tool use in OWUI. Anyway, here is the prompt: When searching the web, use the tool once, then think about the results.
