# Workflows Overview

> Learn about Noxus workflows - powerful visual programming for AI automation

## What are Workflows?

Workflows in Noxus are visual, node-based programs that allow you to create complex AI automation by connecting different functional components. Think of them as flowcharts that can actually execute - each node performs a specific task, and the connections between nodes determine how data flows through your automation.

  <Card title="Nodes" icon="circle">
    Individual functional units that perform specific tasks like text
    generation, data processing, or logic operations
  </Card>

  <Card title="Edges" icon="arrow-right">
    Connections between nodes that define how data flows from one operation to
    another
  </Card>

  <Card title="Inputs & Outputs" icon="arrow-left-right">
    Data entry points and results that allow nodes to communicate with each
    other

## Workflow Architecture

Workflows are built as **directed graphs** where:

* **Nodes** represent operations (AI models, data transformations, logic gates, etc.)
* **Edges** represent data flow between operations
* **Execution** follows the graph structure, processing nodes when their inputs are ready

```mermaid theme={null}
graph LR
    A[Input Node] --> B[Text Generation]
    B --> C[Summary Node]
    B --> D[Analysis Node]
    C --> E[Compose Text]
    D --> E
    E --> F[Output Node]
```

## Node Types

## Workflow Lifecycle

<Steps>
  <Step title="Design">
    Create your workflow by adding nodes and connecting them to define the data
    flow
  </Step>

  <Step title="Configure">
    Set up each node with the appropriate parameters and settings
  </Step>

  <Step title="Validate">
    Ensure all connections are valid and required inputs are provided
  </Step>

  <Step title="Save">Store your workflow definition in the Noxus platform</Step>

  <Step title="Execute">
    Run your workflow with input data and monitor the results
  </Step>

  <Step title="Monitor">
    Track execution progress and handle any errors or issues
  </Step>
</Steps>

## Simple Workflow Example

Here's a basic workflow that takes user input and generates an AI response:

```python theme={null}
from noxus_sdk.client import Client
from noxus_sdk.workflows import WorkflowDefinition

# Initialize client
client = Client(api_key="your_api_key_here")

# Create workflow definition
workflow_def = WorkflowDefinition(name="Simple AI Assistant")

# Add nodes
input_node = workflow_def.node("InputNode").config(
    label="User Question",
    type="str"
)

ai_node = workflow_def.node("TextGenerationNode").config(
    template="Answer this question helpfully: ((User Question))",
    model=["gpt-4o-mini"],
    temperature=0.7,
    max_tokens=200
)

output_node = workflow_def.node("OutputNode")

# Connect nodes
workflow_def.link(input_node.output(), ai_node.input("variables", "User Question"))
workflow_def.link(ai_node.output(), output_node.input())

# Save workflow
workflow = client.workflows.save(workflow_def)
print(f"Created workflow: {workflow.id}")
```

## Complex Workflow Example

Here's a more sophisticated workflow that processes documents:

```python theme={null}
# Create document processing workflow
workflow_def = WorkflowDefinition(name="Document Processor")

# Input nodes
doc_input = workflow_def.node("FileInputNode").config(
    label="Document",
    accepted_types=["pdf", "docx", "txt"]
)

topic_input = workflow_def.node("InputNode").config(
    label="Analysis Topic",
    type="str",
    fixed_value=True,
    value="key insights and recommendations"
)

# Processing nodes
extract_text = workflow_def.node("ExtractTextNode")

summarizer = workflow_def.node("SummaryNode").config(
    summary_format="Bullet Points",
    summary_topic="Main points and conclusions",
    max_length=300
)

analyzer = workflow_def.node("TextGenerationNode").config(
    template="Analyze this document for ((Analysis Topic)):\n\n((Document Text))",
    model=["gpt-4o-mini"],
    temperature=0.3
)

# Combine results
composer = workflow_def.node("ComposeTextNode").config(
    template="""# Document Analysis Report

## Summary
((Summary))

## Analysis
((Analysis))

## Generated on: {{current_date}}
"""
)

output_node = workflow_def.node("OutputNode")

# Connect the workflow
workflow_def.link(doc_input.output(), extract_text.input())
workflow_def.link(extract_text.output(), summarizer.input())
workflow_def.link(extract_text.output(), analyzer.input("variables", "Document Text"))
workflow_def.link(topic_input.output(), analyzer.input("variables", "Analysis Topic"))
workflow_def.link(summarizer.output(), composer.input("variables", "Summary"))
workflow_def.link(analyzer.output(), composer.input("variables", "Analysis"))
workflow_def.link(composer.output(), output_node.input())

# Save the workflow
doc_processor = client.workflows.save(workflow_def)
```
