Google has added Gemini Embedding to its Gemini developer API. This new experimental model for text translates words, phrases and other text inputs into numerical representations, otherwise known as embeddings, which capture their semantic meaning. Embeddings are used in a wide range of applications including document retrieval and classification, potentially reducing costs and improving latency. Google is also testing an expansion of its AI Overviews search feature as part of a Gemini 2.0 update. Called AI Mode, it helps explain complex topics by generating search results that use advanced reasoning and thinking capabilities.

“Trained on the Gemini model itself, this embedding model has inherited Gemini’s understanding of language and nuanced context,” Google explains in a developers’ blog post, adding that it surpasses the company’s prior text embedding model and “achieves the top rank on the Massive Text Embedding Benchmark (MTEB) Multilingual leaderboard,” with new features like longer input token length.

“We’ve trained our model to be remarkably general, delivering exceptional performance across diverse domains, including finance, science, legal, search and more,” the post continues, detailing benchmark scores and applications from Retrieval-Augmented Generation (RAG) to clustering and categorization.

Google claims that compared to its predecessor text-embedding-004 model, Gemini Embedding “can also accept larger chunks of text and code at once” and supports more than 100 languages, twice as many as the earlier version, according to TechCrunch. Gemini Embedding “is in an ‘experimental phase’ with limited capacity and is subject to change.”

The company is targeting a stable, generally available release in the months ahead.

In terms of search, the new AI Mode gives nuanced responses “in one go, rather than having users sieve through multiple searches” as with AI Overviews. This can be helpful when “trying to do a deep dive into a new concept or when comparing varied options,” Android Central reports.

AI Mode can be found as a tab on the Google search bar, to the left of the “All” option. In a blog post, Google says it launched the new feature in response to requests from “power users” who wanted more AI responses.
