The Custom LLM Node allows you to connect any LLM that follows the OpenAI API architecture.
Whether it’s a self-hosted model, a private deployment behind your own domain, or a provider that mimics the OpenAI API spec - you can integrate it directly into your Latenode workflows.
Core fields such as prompt, system message, temperature, max tokens, and more are fully supported.
