Intelligent AI Agent with Dynamic Fallback Models
detail.loadingPreview
Build a robust AI agent that intelligently selects the best Large Language Model (LLM) for your task. This workflow automatically retries with alternative models if the primary choice fails, ensuring consistent performance and reliable output.
About This Workflow
Empower your automation with a sophisticated AI agent capable of dynamic model selection. This n8n workflow leverages the power of Langchain to define a core AI agent, driven by your specific prompts. Crucially, it incorporates a smart fallback mechanism: if the primary LLM encounters an issue, the workflow automatically transitions to a pre-defined list of alternative models, trying them in sequence until a successful response is achieved. This ensures resilience and maximises the chances of task completion, even when facing model availability or performance hiccups. Configure your prompt and sequence your preferred LLMs with ease, creating a truly intelligent and dependable AI assistant.
Key Features
- Dynamic AI Agent: Define and execute complex AI tasks with a flexible agent.
- Intelligent Fallback Chain: Automatically retries tasks with a sequence of configured LLMs upon failure.
- Configurable Model Selection: Easily add and order your preferred AI models (OpenAI, Gemini, etc.) for the fallback chain.
- Retry Count Management: Tracks failures to inform model selection in the fallback sequence.
- User-Friendly Configuration: Clear sticky notes guide you through setting up your prompt and model chain.
How To Use
- Define Your Prompt: Update the
AI Agentnode with your specific instructions or task. - Configure Agent Variables: In the
Agent Variablesnode, you can optionally adjust the default model list (models) or other parameters. - Add Your AI Models: Place your desired AI model nodes (e.g.,
lmChatOpenAi,lmChatGoogleGemini) onto the canvas. - Connect Models to Fallback: Connect the
ai_languageModeloutput of each of your AI model nodes to theai_languageModelinput of theFallback Modelsnode. The order of connection determines the retry sequence. - Trigger the Workflow: Use the
Manual Trigger(or integrate it with another trigger) to initiate the AI agent process.
