Simplifying Agentic Workflows

The AIGNE Framework offers multiple workflow patterns, each tailored to address distinct application scenarios efficiently.

Workflow Patterns

• Workflow Router - Implement intelligent routing logic to direct requests to appropriate handlers based on content.
• Workflow Sequential - Build step-by-step processing pipelines with guaranteed execution order.
• Workflow Concurrency - Optimize performance by processing multiple tasks simultaneously with parallel execution.
• Workflow Handoff - Create seamless transitions between specialized agents to solve complex problems.
• Workflow Reflection - Enable self-improvement through output evaluation and refinement capabilities.
• Workflow Orchestration - Coordinate multiple agents working together in sophisticated processing pipelines.
• Workflow Code Execution - Safely execute dynamically generated code within AI-driven workflows.
• Workflow Group Chat - Share messages and interact with multiple agents in a group chat environment.

Sequential

Use Cases: Processing multi-step tasks that require a specific execution order, such as content generation pipelines, multi-stage data processing, etc.
