Who should pick which

  • Enterprise RAG Engineer
    Pick: Voyage AI

    Needs domain-specific embeddings (finance, legal, code) with 32K context, low-dim vectors for cost efficiency, and SOC 2/HIPAA compliance. Voyage offers fine-tuning and rerankers for high retrieval accuracy.

  • Content Creator / Video Marketer
    Pick: Seedance 2.0 Video AI API

    Wants automated short-form video generation with realistic humans, sound, and camera control via API. Seedance's 720p, aspect ratio flexibility, and async workflow suit scalable production.

  • Startup Building Multimodal App
    Pick: Voyage AI

    If focus is on multimodal retrieval (text+image), Voyage's voyage-multimodal-3.5 and embeddings integrate with vector DBs. For video generation only, Seedance is better.

  • API Developer Testing Video Generation
    Pick: Seedance 2.0 Video AI API

    Free playground to test prompts, REST API with Python/JS examples, and upcoming Seedance 2.5 suggests active development. Perfect for prototyping video features.

  • Legal Tech Company
    Pick: Voyage AI

    Requires specialized legal embedding models, long-context (32K tokens for large documents), and fine-tuning on proprietary contract data. Voyage's domain models and compliance are critical.
