Vendor Tier Classification Workflow orchestrates real-time vendor assessment by routing adjuster requests through a central classifier that integrates structured vendor profiles, historical evaluation data, and local LLM inference. The Vendor Tier Classifier queries vendor_profiles.json and vendor_eval_golden.json for baseline data, retrieves contextual vendor history and trade patterns from ChromaDB Vector Store, and invokes Ollama LLM Server (gemma2:2b and gemma4:e4b models) for intelligent tier recommendations. This architecture enables procurement teams to classify vendors consistently without external API dependencies, maintaining data privacy while leveraging vector similarity search and generative AI. Fork and customize this workflow on Diagrams.so to adapt tier criteria, swap LLM models, or integrate additional data sources.
