Frequently asked questions
Lepton AI FAQs
What models does Lepton AI support?
Lepton AI hosts Llama 3.3 70B and other popular open-weight models. Their catalog is focused on the most widely-used models rather than breadth.
How does Lepton AI pricing compare to competitors?
Lepton AI offers competitive pricing on Llama 3.3 70B, comparable to Together AI and Fireworks AI. Check their pricing page for current rates.
Is Lepton AI good for production workloads?
Lepton AI is suitable for production workloads with auto-scaling and serverless infrastructure. For very high-volume or latency-critical production use cases, Groq or Cerebras may offer better performance.
Voyage AI FAQs
What is Voyage AI used for?
Voyage AI provides embedding and reranking models for RAG pipelines, semantic search, and document retrieval. It does not offer chat or text generation models.
How does Voyage AI compare to OpenAI embeddings?
Voyage 3.5 consistently outperforms OpenAI text-embedding-3-large on MTEB benchmarks while being significantly cheaper. It is the preferred choice for production RAG systems.
