Limitations & Considerations
  • Higher initial investment: Project-based pricing ($10,000+ minimum) significantly higher than SaaS alternatives; not suitable for small businesses or startups with limited budgets
  • Longer implementation timeline: Expect 12-18 month pilot phases before enterprise-wide rollout; implementations take weeks to months vs. hours for self-service platforms
  • Requires technical resources: Organizations need internal development teams to maintain and extend custom solutions post-delivery; not a turnkey solution
  • Services-driven approach: Model selection, configuration, and customization determined by Azumo team vs. self-service dashboard controls
  • Learning curve: Custom systems require significant onboarding and training for client teams to operate and maintain effectively
  • Not ideal for: Simple use cases that can be solved with off-the-shelf tools, organizations seeking rapid deployment without development resources, budget-constrained small businesses
  • 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
  • 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

Pricing Comparison Summary

Azumo starts at $100000/month, while SimplyRetrieve begins at custom pricing. Total cost of ownership should factor in implementation time, training requirements, API usage fees, and ongoing support. Enterprise deployments typically see annual costs ranging from $10,000 to $500,000+ depending on scale and requirements.

Our Recommendation Process

  1. Start with a free trial - Both platforms offer trial periods to test with your actual data
  2. Define success metrics - Response accuracy, latency, user satisfaction, cost per query
  3. Test with real use cases - Don't rely on generic demos; use your production data
  4. Evaluate total cost - Factor in implementation time, training, and ongoing maintenance
  5. Check vendor stability - Review roadmap transparency, update frequency, and support quality

For most organizations, the decision between Azumo and SimplyRetrieve comes down to specific requirements rather than overall superiority. Evaluate both platforms with your actual data during trial periods, focusing on accuracy, latency, ease of integration, and total cost of ownership.
