Who should pick which

  • Enterprise RAG engineer
    Pick: Voyage AI

    Voyage specializes in domain-specific embeddings and rerankers for high-accuracy retrieval on finance/legal documents, with long-context support and low-dimensional vectors.

  • Prompt engineer optimizing token usage
    Pick: Toon

    Toon reduces token consumption by ~40% compared to JSON in LLM prompts, with schema-aware guardrails and deterministic round-tripping.

  • Solo developer building LLM app
    Pick: Toon

    Toon is free, open source, and easy to integrate with multi-language support, making it ideal for cost-sensitive projects.

  • Startup with budget constraints
    Pick: Toon

    Toon has zero cost and no sales process, whereas Voyage requires contacting sales and likely incurs ongoing fees.
