Who should pick which
- Enterprise RAG engineerPick: Voyage AI
Needs high‑accuracy retrieval on finance/legal documents; domain‑specific models and 32K token context are critical. Enterprise pricing and compliance fit corporate requirements.
- AI engineering team leadPick: Mainline
Manages multiple coding agents (Codex, Claude Code) and wants to share decision history via Git. Mainline’s intent records prevent repeated dead ends and detect logic conflicts early.
- Cost‑conscious startupPick: Mainline
Freemium model allows free experimentation. Git‑native approach avoids extra database costs. Good fit if team uses Git and needs agent memory without lock‑in.
- Data scientist building multimodal RAGPick: Voyage AI
Announced voyage‑multimodal‑3.5 enables embedding across text and images. Low‑dim vectors reduce storage, and Batch API handles scale – all essential for multimodal retrieval.
- Open‑source enthusiastPick: Mainline
Mainline works with Git, is extendable via CLI, and doesn’t require a proprietary database. Freemium model and public docs make it easy to adopt in open‑source projects.
