Anthropic LLM Selector

This node establishes a connection with a Large Language Model (LLM) from Anthropic. After successfully authenticating using the Anthropic Authenticator node, you can select a model from a predefined list.

Note: Data sent to the Anthropic API is not used for the training of models by default, but can be if the prompts are flagged for Trust & Safety violations. For more information, check the Anthropic documentation.

Options

Model

The model to use. The available models are fetched from the Anthropic API if possible.

Models with the suffix -latest are the latest snapshots of the respective models. For more consistent behavior, specific snapshots should be used (e.g. claude-3-7-sonnet-20250219).

Temperature

Sampling temperature to use, between 0.0 and 1.0.

Higher values will lead to less deterministic but more creative answers.

Max Tokens

The maximum number of tokens to generate in the response.

Input Ports

: The authentication for the Anthropic API.

Output Ports

: The Anthropic large language model which can be used in the LLM Prompter (Table) and LLM Prompter (Conversation) nodes.
