DeepSeek Web Search Chat Model for n8n

This package is a separate copy of n8n's DeepSeek Chat Model for AI workflows.
It uses DeepSeek's Responses API with deepseek-v4-flash-vision-exp selected by
default. That model accepts image parts as images. Flash and Pro remain available
for text-only workflows.

The node exposes a Web Search setting. Available to Model adds DeepSeek's
server-side web_search tool to every request and lets the model decide whether
to use it. Always Search Before Answering forces that server-side tool. It is
not a separate n8n tool node, so it will not appear among wires connected to the
AI Agent.

It reuses the built-in DeepSeek API credential type. Select a credential whose
base URL is https://api.deepseek.com.

The package requires n8n 2.19.x and the Responses API support present in its
bundled @langchain/openai version.
