OpenAI: text-embedding-3-large · fastrouter
text-embedding-3-large is OpenAI's high-capacity embedding model for text, aimed at delivering the strongest semantic encoding. It produces 3072-dimensional embeddings and achieves the highest accuracy among OpenAI's embedding models (about 64.6% on the MTEB benchmark). Because of its size, it is slower and more costly – around $0.13 per 1K tokens – compared to smaller models. This makes it well-suited to use cases where embedding quality is critical, such as complex document search or analytics. In summary, text-embedding-3-large outperforms both text-embedding-3-small and the older ada-002 model in accuracy at the expense of higher computational cost and latency.
