text-embedding-ada-002

text-embedding-ada-002 is OpenAI's legacy embedding model from December 2022 — the model that defined commercial embedding for nearly a year and a half before being superseded by the text-embedding-3 family. The model produces 1536-dimensional vectors and supports up to 8K tokens of input. At release, ada-002 was dramatically cheaper and higher-quality than OpenAI's earlier embedding models, becoming the de facto standard for production semantic search and RAG applications. Performance on MTEB was strong for its time and the model became foundational to thousands of production AI applications launched in 2023. text-embedding-ada-002 remains in production at many organizations due to migration cost (re-embedding entire content libraries is expensive) and proven stability. OpenAI continues to host the API alongside newer models. Pricing remained competitive at $0.10 per million tokens. AI governance, AI compliance, and AI risk management programs track ada-002 as a legacy deployment requiring migration planning — supporting responsible AI through version management and embedding-pipeline modernization across enterprise AI deployments.
