Connect to an embeddings model that runs on the local machine via GPT4All. The default model was trained on sentences and short paragraphs of English text. It ignores special characters like 'ß' i.e. the embeddings for 'Schloß' are the same as for 'Schlo'. If downstream nodes fail with 'Execute failed: Error while sending a command.', then this is likely caused by an input that consists entirely of characters the model doesn't support.
Note: Unlike the other GPT4All nodes, this node can be used on the KNIME Hub.
