OpenAIEmbeddingProvider

OpenAI embedding provider implementation.

Provides text embeddings using OpenAI's embedding API (text-embedding-3-small, text-embedding-3-large, text-embedding-ada-002). Supports batch embedding of multiple texts in a single request.

== Supported Models ==

• text-embedding-3-small - Efficient, lower cost (recommended)
• text-embedding-3-large - Higher quality, higher cost
• text-embedding-ada-002 - Legacy model

== Token Usage == The response includes token usage information when available from the API.

OpenAI's entry in the embedding half of the provider SPI.

The object that builds the provider is also its org.llm4s.llmconnect.spi.EmbeddingProviderDescriptor, so there is one place per provider rather than a descriptor shadowing a factory.
