LLM

ai/llm Component: v0.29.0+ AI text generation component that produces content based on large language model understanding of user inputs, context, or images.

Supports all OpenAI API-compatible large model platforms, such as:

# Configuration

Field Type Description Default
url string API endpoint URL https://ai.gitee.com/v1/
key string API Key
model string Model name (e.g., gpt-3.5-turbo, DeepSeek-R1)
systemPrompt string System prompt defining model behavior and response style. Supports ${} variables
messages []ChatMessage Context/user message list (each with role/user and content)
images []string Images provided to the model for visual understanding
params Params Large model parameters

# Params Structure

Field Type Description Default
temperature float32 Sampling temperature controlling output randomness [0.0, 2.0] 0.0
topP float32 Nucleus sampling: select from top p% tokens [0.0, 1.0] 0.0
presencePenalty float32 Penalize new tokens based on existing presence [0.0, 1.0] 0.0
frequencyPenalty float32 Penalize new tokens based on existing frequency [0.0, 1.0] 0.0
maxTokens int Maximum output length
stop []string Stop sequences
responseFormat string Output format: text/json_object/json_schema text
jsonSchema string JSON Schema definition
keepThink bool Retain reasoning process (text format only) false

# ChatMessage Structure

Field Type Description
role string Message role: user or assistant
content string Content with ${} variable support

# Execution Result

Result replaces msg.Data and flows to next node.The output format is determined by params.responseFormat.
