Who should pick which

  • Enterprise RAG developer for finance/legal
    Pick: Voyage AI

    Voyage AI offers domain-specific models for finance and legal, with 32K token context and low-dimensional embeddings for efficient storage.

  • Startup building an AI API with usage billing
    Pick: OpenMeter

    OpenMeter provides real-time metering, entitlements, and Stripe sync, with a free tier to start and transparent usage-based pricing.

  • Solo developer needing free embeddings for RAG
    Pick: Voyage AI

    Voyage AI's lite models are likely cost-effective, but without public pricing a solo developer may struggle. Consider OpenMeter not applicable here.

    OpenMeter's multi-subject per customer and low-latency entitlement enforcement are ideal for platform usage gating.
