Frequently Asked Questions
Kento vs Voyage AI: which should you choose?
Choose Kento if your primary goal is to slash LLM API costs on repetitive queries with zero integration hassle—it's perfect for cost-conscious teams using major providers. Choose Voyage AI if you need state-of-the-art embedding/reranker models for high-accuracy RAG, especially in finance, legal, or code domains. They solve different problems; Kento saves money on inference, Voyage improves retrieval quality.
Can I use Kento with Voyage AI's embeddings?
Yes, Kento caches LLM API calls regardless of how embeddings are generated. Using Voyage for retrieval and Kento for caching inference is complementary.
Does Kento support Voyage AI's API?
No, Kento's integrations are limited to OpenAI, Anthropic, and Google Gemini. Voyage is not one of them.
Can Voyage AI be used without a sales call?
No, pricing is contact-only, but you can sign up for API access and test with a free trial on their website (not detailed here).
Which tool is better for reducing latency?
Kento reduces latency by returning cached responses instantly. Voyage's low-latency inference on small models helps, but Kento is explicitly designed for speed.
Do both tools support HIPAA?
Both offer HIPAA compliance on enterprise plans. Kento requires Enterprise tier; Voyage likely needs contractual agreement.
Which tool is more cost-effective for a startup?
Kento's free tier and $19/mo Startup plan make it far more accessible. Voyage's pricing is opaque and likely higher.
Can I self-host Kento or Voyage?
Kento offers on-premise deployment for Enterprise. Voyage does not mention on-premise; it's cloud API only.
Which tool has better document retrieval accuracy?
Voyage is specialized for retrieval (embeddings + rerankers). Kento does not affect retrieval accuracy; it only caches LLM responses.
