# I am getting a "Model deprecated. See docs for new model information" error message. What does it mean?

If you receive an error message indicating `Model deprecated, see our docs for new model information: https://www.assemblyai.com/docs/streaming`, it means you are using an older version of our Real-time STT feature that is no longer supported.

## How to upgrade to a supported streaming model

You'll need to update your implementation to use one of our current streaming models. We recommend **Universal-3 Pro Streaming** (`u3-rt-pro`) as the primary streaming model. It delivers the highest accuracy with sub-300ms latency and native code switching across English, Spanish, German, French, Portuguese, and Italian.

1. Review the [Streaming documentation](/streaming) for model selection and implementation guidance.

2. For a quick start guide, see our [Getting Started with Streaming Audio](/streaming/getting-started/transcribe-streaming-audio) documentation.

<Note>
  Universal-3 Pro Streaming and the Universal-Streaming family of models offer
  improved accuracy and reliability compared to our legacy streaming
  implementation.
