n8n-nodes-volcengine-ai

This is an n8n community node that allows you to use VolcEngine AI services in n8n workflows, including chat completion and code completion functionality.

This node supports the following VolcEngine AI services:

• Chat Completion: Provides intelligent conversation capabilities with support for multi-turn conversations and rich parameter configuration
• FIM Completion (Fill-In-the-Middle): Provides code completion and filling functionality, supporting middle-part filling in code

Through this node, you can easily integrate VolcEngine's AI capabilities into your automation workflows to achieve intelligent conversations, content generation, code assistance, and more.

n8n is a workflow automation platform with a fair-code license.
