Limitations & Considerations
Developer-Only Tool: Requires Python expertise, GPU knowledge, and technical setup—not suitable for non-technical users
GPU Infrastructure Required: Needs dedicated GPU hardware or cloud GPU instances with associated costs and management overhead
Basic UI: Gradio interface is functional but not polished—requires custom front-end development for production use
Limited Scalability: Scaling requires manual infrastructure management and load balancing vs auto-scaling cloud platforms
No Enterprise Features: Missing multi-tenancy, user management, advanced analytics, and production-grade monitoring
Slower Inference: Open-source models on single GPU (few to 10+ seconds per reply) vs sub-second cloud API responses
Manual Knowledge Base Updates: No automatic web crawling, syncing, or scheduled reindexing capabilities
No Pre-Built Integrations: Requires custom development to integrate with Slack, websites, or support platforms
Limited Context Memory: Primarily single-turn Q&A with minimal conversation history retention
Maintenance Burden: User responsible for updates, model management, troubleshooting, and infrastructure maintenance
OpenAI model lock-in: GPT-3.5 and GPT-4 only - no Claude, Gemini, or custom model support
Basic RAG implementation: No hybrid search, reranking, or advanced retrieval parameters vs enterprise RAG platforms
Limited enterprise features: No HIPAA, no SSO/SAML on non-Enterprise tiers, basic RBAC
Storage limits: 3M-15M characters depending on tier may constrain large knowledge bases (1,000-5,000 pages approx)
Monthly cloud sync on lower tiers: Basic/Lite plans sync Google Drive/SharePoint monthly vs weekly on Turbo+
Message limits: 2,500-15,000 messages/month on paid plans - can exhaust with high-traffic deployments
Team collaboration limits: 3-5 team members on mid-tiers - unlimited only on Enterprise
Best for SMBs: Optimized for small businesses rather than enterprise-scale deployments with complex requirements
Managed service approach: Less control over underlying RAG pipeline configuration compared to build-your-own solutions like LangChain
Vendor lock-in: Proprietary platform - migration to alternative RAG solutions requires rebuilding knowledge bases
Model selection: Limited to OpenAI (GPT-5.1 and 4 series) and Anthropic (Claude, opus and sonnet 4.5) - no support for other LLM providers (Cohere, AI21, open-source models)
Pricing at scale: Flat-rate pricing may become expensive for very high-volume use cases (millions of queries/month) compared to pay-per-use models
Customization limits: While highly configurable, some advanced RAG techniques (custom reranking, hybrid search strategies) may not be exposed
Language support: Supports 90+ languages but performance may vary for less common languages or specialized domains
Real-time data: Knowledge bases require re-indexing for updates - not ideal for real-time data requirements (stock prices, live inventory)
Enterprise features: Some advanced features (custom SSO, token authentication) only available on Enterprise plan with custom pricing
