Hacker News, YouTube, App Store, Stack Overflow, GitHub, Lemmy
What users praise
- • Domain-tuned embedders for finance, legal, and code deliver measurable retrieval precision gains
- • Harvey case study showed 25% fewer irrelevant documents and 3x lower vectorDB costs
- • Low-dimensional embeddings (3x-8x shorter vectors) cut storage and search costs materially
- • Instruction-following rerank-2.5 and rerank-2.5-lite let you steer ranking behavior in plain language
What frustrates them
- • Terms grant Voyage an irrevocable license to train on API customer data by default
- • Usage-based pricing at $0.12-$0.18 per million tokens can balloon for high-frequency agents
- • A community benchmarker found a small Jina model outperformed Voyage for their use case
- • Circular import bug in voyageai v0.3.5 broke lazy import systems before being fixed
