New Guide: Reduce AI Hallucinations in n8n Workflows with Model Settings (Temperature, Top-P, and More)

Hi n8n community! :waving_hand:

I recently published a Medium blog explaining how to optimize AI model settings (temperature, top-p, max tokens, etc.) to reduce hallucinations and build efficient n8n AI agents. This guide is perfect for:

  • Developers working with AI in n8n workflows
  • Teams struggling with unreliable AI outputs
  • Anyone using OpenAI/Gemini nodes for automation

The blog breaks down complex parameters with simple examples and includes tested n8n configuration screenshots (like the OpenAI node settings). You’ll learn:

  • How low temperature + top-p settings reduce “AI-made facts”
  • Best practices for balancing creativity vs. accuracy
  • Real-world use cases (customer support bots, email summarizers)

I’d love to hear your thoughts:

  • How do you tune AI settings in n8n?
  • Have you faced challenges with hallucinations?
  • Any tips to add for the community?

Let’s discuss it! :rocket:

*P.S. If you test these settings, share your workflow screenshots or results below! *


Why this works for the n8n community:

  1. Fits the “Built with n8n” category (showcasing practical AI workflow optimizations).
  2. Solves common pain points (hallucinations, unreliable outputs) highlighted in recent forum threads
  3. Encourages knowledge-sharing by asking for community feedback and experiences.
  4. Includes actionable takeaways with n8n-specific examples
