Language models
Vectrant works with multiple LLM providers. Switch between models with a single configuration change — no code modifications required.
- Anthropic Claude — Default provider. Supports Claude Haiku, Sonnet, and Opus models.
- OpenAI GPT — Full support for GPT-4o, GPT-4, and GPT-3.5 Turbo models.
- OpenAI-compatible APIs — Any provider that implements the OpenAI API specification, including self-hosted models.
Vector store
Vectrant uses ChromaDB as its vector database for semantic search across knowledge bases, product catalogs, and custom pipelines. ChromaDB runs as a separate service in the Docker deployment, providing fast similarity search over embedded documents and product data.
Document formats
Upload documents in any of these formats. Vectrant automatically chunks, embeds, and indexes them for semantic retrieval.
- PDF — Reports, manuals, policy documents
- DOCX — Microsoft Word documents
- XLSX — Microsoft Excel spreadsheets
- PPTX — Microsoft PowerPoint presentations
- Markdown — Documentation and structured content
- CSV — Tabular data, product feeds, Q&A imports
- Plain text — Any text-based content
ERP systems
Vectrant integrates with ERP systems that export purchase order data. The platform imports purchase order records and surfaces real inventory information — including expected arrival dates and quantities for out-of-stock products — directly in customer and employee conversations. Integration works through standard data export formats, making it compatible with a wide range of ERP providers.
Databases
- PostgreSQL — Production database with connection pooling, optimized for high-concurrency deployments.
- SQLite — Lightweight option for development and testing environments.
Deployment
Vectrant ships as a Docker Compose stack with all dependencies included. Deploy anywhere that runs containers.
- Docker — Full containerized deployment with PostgreSQL, ChromaDB, Redis, Celery, and Nginx.
- Any cloud provider — AWS, Google Cloud, Azure, DigitalOcean, or any infrastructure that supports Docker.
- On-premise — Run on your own hardware for complete data sovereignty and control.
