Litellm now fully supports Gemini Embedding 2 GA.
For end-to-end behavior, input shapes, and MIME types, see the Gemini Embedding 2 Preview walkthrough. This post focuses on GA naming, cost map coverage.
LiteLLM now supports gemini-3.1-flash-lite-preview with full day 0 support!
If you only want cost tracking, you need no change in your current Litellm version. But if you want the support for new features introduced along with it like thinking levels, you will need to use v1.80.8-stable.1 or above.

LiteLLM now supports multimodal embeddings with gemini-embedding-2-preview—mixing text, images, audio, video, and PDF content in a single request. Available via both the Gemini API (API key) and Vertex AI (GCP credentials).
gemini/...): each input element returns its own embedding, indexed 0..N-1 — same shape as OpenAI's /embeddings. LiteLLM routes to the batchEmbedContents endpoint with one EmbedContentRequest per input.vertex_ai/...): all input elements are combined into a single unified embedding via embedContent. Vertex AI does not expose batchEmbedContents for Gemini embedding models, so N parts → 1 vector. To get one vector per item, call embedding(...) once per input.
