Who should pick which
- Enterprise RAG engineerPick: Voyage AI
Voyage AI's domain-specific embeddings and rerankers improve retrieval accuracy for finance/legal documents, and long-context support (32K tokens) suits complex RAG pipelines. Cloud API with SOC 2/HIPAA compliance meets enterprise requirements.
- Privacy-focused developerPick: Vmlx
vMLX runs fully offline on Apple Silicon, keeping all data local. It's free and open-source, with advanced caching for low-latency inference, ideal for building local AI assistants without cloud dependency.
- Mac power user running agentsPick: Vmlx
vMLX's native MCP tool support allows agents to control local tools directly. Continuous batching and multi-context prefix caching enable high throughput for concurrent agent sessions, all on a single Mac.
- Startup building RAG on a budgetPick: Voyage AI
Even though Voyage pricing is opaque, its low-dimensional embeddings reduce vector storage costs, and batch API scales affordably for large datasets. Startups needing best-in-class retrieval may justify the expense.
