Embeddings

LLMGateway exposes an OpenAI-compatible /v1/embeddings endpoint for generating vector representations of text — useful for semantic search, clustering, recommendations, and RAG.

Browse available embedding models on the models page.

Supported providers

• OpenAI — text-embedding-3-small, text-embedding-3-large, text-embedding-ada-002
• Google AI Studio — gemini-embedding-2 (recommended), gemini-embedding-001 (legacy)
• Google Vertex AI — gemini-embedding-001, text-embedding-005

The gateway translates between provider-native request/response shapes (e.g. Google's :embedContent / :batchEmbedContents) and the OpenAI-compatible payload, so you can swap models without changing your client code.
