Volcengine Ark Chat Model (Next)

AI-generated

Summary

Provides a Volcengine Ark Doubao chat model for an n8n AI Agent or AI Chain. Select a model and configure options such as streaming, thinking mode, sampling, response format, and extra Ark arguments; the node supplies the configured language model to the connected AI node.

Inputs

  • Model (required) — Volcengine Ark model ID. The node loads choices from the Ark /models endpoint when available and falls back to a static list if the request fails or returns no usable models. Defaults to doubao-seed-2-0-pro-260215.
  • Options — Optional model settings: Thinking Mode (disabled by default; enabling sends thinking: { type: "enabled" } and requires a thinking-capable model), Stream (enabled by default), Parallel Tool Calls (disabled by default), Sampling Temperature, Top P, Frequency Penalty, Presence Penalty, Maximum Number of Tokens, Response Format, Timeout, Max Retries, and Additional Model Arguments. A token limit below zero is omitted. Additional Model Arguments must be a JSON object and are merged into the model arguments; invalid JSON or a non-object value raises an error. When using JSON Object response format, include “json” in the prompt if required by the provider.

Output shape

A single AI language model connection for an AI Agent or AI Chain.

The node makes chat-completion requests using the required Volcengine Ark API credentials. It normalizes tool parameter schemas and carries reasoning content across continuation requests involving tool calls. With thinking mode disabled, reasoning stream deltas are also mirrored into assistant text for n8n AI Agent streaming aggregation.
