LLM Chain Chatbot with Documentation & Web Search Integration

This workflow automates basic AI responses using Mistral Cloud, replacing manual API calls or console testing that take 5-10 minutes per query for developers prototyping LLMs. The Manual Trigger starts with a prompt, the Input Validation Set node prepares text, the Mistral Cloud Chat ChainLLM node generates output with mistral-tiny model at temperature 0 for precision, the Check Response If node verifies non-empty, and Format Success Response Set outputs JSON. Error paths (Format Error Response Set) handle empty results. It helps developers in small AI teams (5-15 staff) testing 50+ prompts weekly, ensuring quick, consistent responses without code setup, streamlining model evaluation and integration prototyping.\n\nThis workflow saves 2-4 hours weekly on 50 prompts, accelerating iteration by 80%. Use cases include LLM benchmarking for startups, response validation for chatbots in agencies. Suitable for solo devs or small teams. Requires Mistral Cloud API (free tier with limits, $0.25/1M tokens); n8n (free self-hosted or $20/month cloud). Scalable to 200 prompts/day with paid tiers.\n\nInstall n8n via n8n.io or cloud.n8n.io. Get Mistral key at console.mistral.ai (create project, generate API key). Set MISTRAL_API_KEY env var. Import JSON; manual trigger—no webhook. Configure Mistral Cloud Chat Model with 'mistral-tiny' and key.\n\nTest manually: Set prompt='1+1?'. Verify numerical response. Errors: Empty prompt (error JSON), invalid key (500—regenerate). Activate workflow. Monitor dashboard weekly.
