text-embedding-ada-002: OpenAI's Legacy Embedding Model
Model Overview
text-embedding-ada-002 is OpenAI's previous-generation text embedding model, widely used for semantic search, clustering, and RAG applications since its release in December 2022. Producing 1536-dimensional embeddings from text, Ada-002 replaced all previous OpenAI embedding models with a single unified endpoint. While superseded by the text-embedding-3 series (released January 2024) in terms of performance and cost, Ada-002 remains in use for many production applications built before 2024.
✨ Key Features
| Feature | Description |
|---|---|
| 1536 Dimensions | Unified embedding space for all text types |
| Legacy Reliability | Battle-tested in production across millions of applications worldwide |
| Simple API | Single endpoint replacing all prior OpenAI embedding models |
| Multilingual | Handles text in many languages |
⚠️ Deprecation Note
OpenAI recommends migrating to text-embedding-3-small or text-embedding-3-large, which offer significantly better performance at lower cost. Ada-002 remains available for backward compatibility.
