OpenAI: text-embedding-ada-002 · fastrouter

text-embedding-ada-002 (often called ada v2) is an earlier-generation OpenAI embedding model for general semantic tasks like text and code search, clustering, and classification. It produces 1536-dimensional embeddings and was initially state-of-the-art for tasks such as text search, code search, and sentence similarity. Its performance on benchmarks is moderate (around 61% on MTEB), and it costs about $0.10 per 1K tokens. Ada-002 is suited to general retrieval and similarity tasks but is generally considered a legacy model; newer v3 models (3-small and 3-large) have mostly superseded it for better efficiency or accuracy. In fact, documentation notes that ada-002 is primarily kept for legacy use cases, while most new applications use the 3-small or 3-large models for improved performance.
