Voyage AI voyage-code-3

حول Voyage AI

تأسس في 2023 · Palo Alto, California, USA

Voyage AI was founded in 2023 by Stanford CS professor Tengyu Ma and team, focused on best-in-class retrieval and reranking models for RAG, with a particular emphasis on domain-specific variants. The company has shipped specialised embeddings for finance (voyage-finance-2), law (voyage-law-2), multilingual (voyage-multilingual-2) and code (voyage-code-2 then voyage-code-3). voyage-code-3 launched in December 2024 as the successor to voyage-code-2 and quickly became the top-scoring code embedding model on the CoIR and CodeSearchNet benchmarks. In February 2025 Voyage AI was acquired by MongoDB for $220M, with voyage-code-3 now integrated into MongoDB Atlas Vector Search and recommended for code-aware AI agents and IDE-style retrieval workloads.

العمارة

Transformer bi-encoder specialised for code and technical text with Matryoshka heads

Voyage AI voyage-code-3 is a hosted embedding model specialised for source code, technical documentation, commit messages, issues, pull-request reviews and code-mixed natural language. It has the same 32,000-token context window as voyage-3 and supports Matryoshka-style heads at 256 / 512 / 1,024 / 2,048 dimensions, plus int8 / binary quantisation. Training used a contrastive retrieval objective on curated pairs covering more than 30 programming languages (Python, JavaScript, TypeScript, Go, Rust, Java, C/C++, C#, SQL, Bash, etc.) together with technical natural-language text, with deliberate emphasis on code-to-text and text-to-code retrieval as well as code-clone detection. Voyage reports voyage-code-3 outperforming OpenAI text-embedding-3-large by 13.8 points on average across CoIR sub-tasks while costing the same. The model is offered through the Voyage API and natively in MongoDB Atlas Vector Search after the February 2025 acquisition.
