Reliability Concerns: Users found framework "unreliable and difficult to fix" due to complex structure - production issues and maintainability risks
Framework Fragility: Unexpected production issues as applications become more complex - stability concerns for mission-critical systems
DIY Everything: Security, compliance, UI, monitoring, deployment all require custom development - high engineering overhead vs managed platforms
NOT Ideal For: Non-technical users, teams without Python/JS expertise, rapid prototyping without coding, organizations preferring managed services, projects needing stable APIs without breaking changes
When to Avoid: "When projects move beyond trivial prototypes" per critics who argue it becomes "a liability" due to complexity and productivity drag
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
