Use Case Decision Guide

Choose SynapCores If:

• Building AI-first application
• Need real-time ML inference (<10ms)
• Processing multimodal data (images, video, audio)
• Want embedded AutoML capabilities
• Starting new project (no PostgreSQL lock-in)
• Require production-grade clustering
• Multi-tenant SaaS platform
• Care about long-term TCO

Choose pgvector If:

• Already using PostgreSQL
• Only need basic vector search
• Have PostgreSQL expertise
• Require PostgreSQL ecosystem tools
• Small team or MVP project
• Compliance tied to PostgreSQL
• Using BI tools (Tableau, PowerBI)
• Need sparse or binary vectors

Consider Hybrid Approach If:

• Large existing PostgreSQL deployment
• Want to test SynapCores for new features
• Phased migration strategy
• Separate OLTP (pgvector) and AI (SynapCores) workloads

Strategic Paths

1. All-in on SynapCores

• Greenfield AI projects
• AI-first startups
• Long-term TCO optimization

2. All-in on pgvector

• Existing PostgreSQL shops
• Simple vector search needs
• Small teams/MVPs

3. Hybrid Approach

• Large enterprises
• Phased AI transformation
• Risk mitigation strategy

Conclusion

The choice between SynapCores and pgvector depends on your specific use case:

• For vector search alone: pgvector is sufficient
• For AI + vectors: SynapCores is superior
• For existing PostgreSQL: Start with pgvector, evolve to SynapCores for AI workloads

Bottom Line: SynapCores' 38% TCO advantage and 10-100x ML performance gains make it compelling for any organization serious about AI, while pgvector remains the pragmatic choice for incremental vector search adoption.
