## New models in Workers AI

Mar 17, 2025

[Workers AI](https://developers.cloudflare.com/workers-ai/)

Workers AI is excited to add 4 new models to the catalog, including 2 brand new classes of models with a text-to-speech and reranker model. Introducing:

* [@cf/baai/bge-m3](https://developers.cloudflare.com/workers-ai/models/bge-m3/) - a multi-lingual embeddings model that supports over 100 languages. It can also simultaneously perform dense retrieval, multi-vector retrieval, and sparse retrieval, with the ability to process inputs of different granularities.
* [@cf/baai/bge-reranker-base](https://developers.cloudflare.com/workers-ai/models/bge-reranker-base/) - our first reranker model! Rerankers are a type of text classification model that takes a query and context, and outputs a similarity score between the two. When used in RAG systems, you can use a reranker after the initial vector search to find the most relevant documents to return to a user by reranking the outputs.
* [@cf/openai/whisper-large-v3-turbo](https://developers.cloudflare.com/workers-ai/models/whisper-large-v3-turbo/) - a faster, more accurate speech-to-text model. This model was added earlier but is graduating out of beta with pricing included today.
* [@cf/myshell-ai/melotts](https://developers.cloudflare.com/workers-ai/models/melotts/) - our first text-to-speech model that allows users to generate an MP3 with voice audio from inputted text.

Pricing is available for each of these models on the [Workers AI pricing page](https://developers.cloudflare.com/workers-ai/platform/pricing/).

This docs update includes a few minor bug fixes to the model schema for llama-guard, llama-3.2-1b, which you can review on the [product changelog](https://developers.cloudflare.com/workers-ai/changelog/).

Try it out and let us know what you think! Stay tuned for more models in the coming days.
