Descriptions:
Bart Slodyczka explores n8n’s newly released Chat Hub, a built-in ChatGPT-style conversational interface that lets users chat with any AI model — including GPT-5.2, Claude, and Google models — simply by supplying an API key. For developers already paying for n8n, this effectively replaces the need for separate ChatGPT or Claude subscriptions when using AI as a coding or workflow assistant, consolidating everything into one platform.
The tutorial covers Chat Hub’s native capabilities: voice input, file uploads, and multimodal image understanding, all demonstrated without any custom configuration. Bart then moves into building custom agents within n8n’s canvas — the platform’s answer to OpenAI’s Custom GPTs — showing how to connect an agent to web search tools, configure system prompts, and publish updated versions. A standout example builds a custom agent called “Bartman” with real-time weather lookup via web search, with file upload support enabled through the chat node settings.
The most technically interesting segment walks through adding a model selector node to a custom agent workflow, allowing the system to dynamically route user queries to different models based on complexity — mirroring ChatGPT’s instant versus thinking mode behavior. Bart argues this pattern gives n8n builders granular control over cost and capability tradeoffs that the standard Chat Hub interface doesn’t expose, and frames Chat Hub overall as a meaningful step toward making n8n a self-contained AI development environment.
