Send a prompt, with the incoming data filled in, to a connected language model and return its reply in one straight pass with no tools.

Supply a Google Gemini chat model, with its key and settings, as the brain that an agent, chain or extractor step uses.

Keep the last few turns of a conversation in memory and feed them back to the model so it remembers recent context per chat session.

Send a plain text or HTML message with attachments through any SMTP mail server, without being tied to one mail provider.

Supply a chat model served through OpenRouter, giving steps access to many vendors' models behind one key.
