Who should pick which

  • Enterprise legal team building RAG over contracts
    Pick: Voyage AI

    Voyage AI offers a legal-specific embedding model and rerankers, plus HIPAA/SOC 2 compliance. Mini Infer provides no retrieval capabilities.

  • AI PhD student studying inference optimization
    Pick: Mini Infer

    Mini Infer's open-source codebase and 25-part educational series teach PagedAttention, speculative decoding, and CUDA graph techniques.

  • Startup building a custom serving stack on a budget
    Pick: Mini Infer

    Free license and full control over the inference engine allow cost savings, provided the team has GPU programming skills.

  • Finance firm needing long-context embeddings for reports
    Pick: Voyage AI

    Voyage AI's 32K token context and domain-specific finance model directly address this need, with low-dimensional vectors reducing storage costs.

  • Independent developer experimenting with RAG
    Pick: Voyage AI

    While Mini Infer is free, Voyage AI provides a managed API with ready-to-use embedding models, saving time on infrastructure and model training.
