Stop Chasing AI Dreams, Start Building Real-World Solutions

Why many AI implementations fail at scale despite strong pilot performance, and how to build production-ready systems with rigorous testing, scalable infrastructure, and cost optimization.

The Production Gap

Many AI implementations fail at scale despite strong pilot performance. The gap between a successful demo and a production system is vast-and often underestimated.

Production-ready AI systems require careful problem selection, rigorous testing, scalable infrastructure, and cost optimization-not just powerful models.


Identifying AI-Ready Problems

Not every problem requires an AI solution. Before implementation, organizations should ask:

  • What business challenge needs solving?
  • What’s the optimal solution approach?

“You have to think hard – ‘What is the right solution to my problem?’ And not – ‘Oh I have an LLM, where can I use it?’”

Deterministic vs. AI Solutions

Deterministic solutions (traditional code) often outperform AI for suitable use cases:

  • Rule-based classification → Faster, cheaper, more reliable
  • Template-based responses → Consistent, predictable output
  • Structured data queries → SQL beats RAG for precise lookups

Clear business value linkage is essential before proceeding with an AI approach.


Testing AI Systems

Technical vs. Business Metrics

While traditional metrics like ROC and AUC matter, they’re insufficient alone. Business impact testing proves critical because LLMs hallucinate and accuracy varies.

Key insight: A model that’s only 75% accurate but can help you reduce operations cost by 50% is far more valuable than a model that’s 99% accurate but can’t be put into production!

Human-in-the-Loop Approach

Treat AI systems like junior employees:

  1. Start with supervised oversight
  2. Begin with smaller, lower-risk tasks
  3. Gradually increase complexity
  4. Build confidence before full deployment

This approach mirrors how you’d onboard any new team member.

Handling Subjective Outputs

For generative AI, a four-category evaluation framework addresses subjectivity:

  • Context: Is relevant information present?
  • Wordiness: Appropriate conciseness/detail balance?
  • Authenticity: Genuine, appropriate tone?
  • Repetitiveness: Avoids unnecessary duplication?

Gather feedback from at least 5 customer stakeholders to prevent individual bias from skewing evaluation.


Scaling: Production Challenges

Three critical components enable production scaling:

Data Processing Scale

Handling millions of datapoints across formats and content types efficiently. This means:

  • Parallel processing pipelines
  • Incremental indexing
  • Format-agnostic ingestion
  • Quality validation at scale

Query Processing Scale

Supporting millions of queries per second while maintaining performance:

  • Load balancing and auto-scaling
  • Caching strategies for common queries
  • Graceful degradation under load
  • Response time SLAs

System Infrastructure Scale

Proper compute resource allocation and architecture designed for failure resilience:

  • Redundancy at every layer
  • Automated failover
  • Geographic distribution
  • Monitoring and alerting

Vector Database Selection

For our multi-modal semantic search (Elastiq Pixels), we benchmarked billion-scale embeddings across multiple databases.

Why We Chose OpenSearch

We selected OpenSearch because it:

  • Functions as a true distributed system - Not just a single-node solution with replication
  • Scales horizontally and vertically - Add nodes or upgrade hardware as needed
  • Maintains billion-dataset performance - Proven at the scale we need
  • Delivers strong price-performance ratios - Cost-effective for our workload
  • Enables fast ingestion and reindexing - Critical for keeping data fresh

The Selection Process

We tested against:

  • Pinecone
  • Weaviate
  • Milvus
  • Qdrant
  • pgvector

Each has strengths, but for billion-scale multimodal search with complex filtering requirements, OpenSearch provided the best balance of capabilities.

Technology Stack
OpenSearch - Billion-scale vector search
Kubernetes - Container orchestration at scale
Vertex AI - Model serving infrastructure
Cloud Monitoring - Observability and alerting

Cost Optimization

Understanding token economics proves essential. One token approximates four characters or one word.

Cost Reduction Levers

Model Selection

Match model capability to specific tasks rather than defaulting to premium models everywhere:

  • Classification tasks → Smaller, faster models
  • Simple extraction → Fine-tuned small models
  • Complex reasoning → Premium models only when needed

Governance and FinOps

Implement proper cost controls:

  • Quotas per department/project
  • API interceptor layers for monitoring
  • Token usage dashboards
  • Chargeback mechanisms

Architecture Optimization

Decouple components for independent scaling:

  • Separate inference from retrieval
  • Cache common queries
  • Batch similar requests
  • Use async processing where latency allows

Team Investment

“Upskill your Solution Architects & Enterprise Architects…they will be your gateway to save a lot of costs – their ROI is high!”

A skilled architect who prevents unnecessary API calls or selects the right model saves more than their salary in AI costs.


Production Checklist

Before going live, ensure you have:

Testing

  • Business metric validation (not just ML metrics)
  • Edge case handling documented
  • Hallucination detection mechanisms
  • Human review process for high-stakes outputs

Infrastructure

  • Horizontal scaling capability
  • Monitoring and alerting
  • Disaster recovery plan
  • Geographic redundancy (if needed)

Cost Management

  • Token usage tracking
  • Budget alerts
  • Model selection guidelines
  • FinOps review process

Operations

  • Runbooks for common issues
  • Escalation paths defined
  • SLAs documented
  • Feedback collection mechanism

Conclusion

Stop chasing AI dreams. Start building real-world solutions.

Select AI solutions strategically where they deliver genuine, measurable business value. Production readiness demands:

  • Comprehensive testing frameworks - Beyond accuracy to business impact
  • Appropriate infrastructure selection - Matched to your scale requirements
  • Quality oversight - Human-in-the-loop for high-stakes decisions
  • Disciplined cost-performance management - Not just “make it work”

The most advanced model isn’t always the right choice. The right choice is the one that solves your specific problem reliably, at acceptable cost, with appropriate oversight.
