MiniMax Chat Model node added to n8n integrations
n8n workflows can now tap into MiniMax's AI models directly, with a new sub-node that handles region differences and strips reasoning tags from responses automatically.
n8n users who rely on the MiniMax AI platform can now build those workflows natively. A new MiniMax Chat Model sub-node has landed in the LangChain integration suite, letting AI Agents call MiniMax models without custom HTTP request nodes or workarounds.
The node ships with seven MiniMax models preconfigured, defaulting to the M2.7 variant. A region selector handles the International and China endpoints transparently — no manual URL patching required. The credential type includes built-in validation that returns clear error messages for authentication failures versus invalid keys.
One standout option: "Hide Thinking." MiniMax models return chain-of-thought reasoning wrapped in <think> tags. The new node strips these by default, returning clean responses to downstream nodes. Toggle it off, and the raw reasoning appears for workflows that need it.
This lands in the 2.17.x release track as a backport from the main branch.
