<Update label="Human ↔ Human" tags={["Models","Accounts"]} description="New Models: AT5.2 and Language Translation">
  ## Accent Translation (`AT5.2`) and Language Translation  Are Now Available

  Two new Human ↔ Human models are live on the Sanas Developer Platform:

  * **`AT5.2`** (Accent Translation): Modifies accents in real time so every speaker is instantly understood, while preserving what makes their voice their own.
  * [LT Documentation](/Docs/Models/Human-Human/Language-Translation/Language-Translation) (Language Translation): Translates conversations across languages in real time, preserving each speaker's tone and intent with no interpreter delay.

<Update label="AI Voice Agent" tags={["Models"]} description="New Models">
  ## Two New Models Replace `AGENTIC_SE`

  `AGENTIC_SE` is deprecated and replaced by two specialized models:

  * **`AGENTIC_VI_G_NC`** (Default): Removes environmental background noise **and** distant human voices from the primary speaker's audio stream
  * **`AGENTIC_ST_NC`**: Removes environmental background noise while **preserving** distant human speech

  ### Migration

  Update `audio_params.modelName` from `"AGENTIC_SE"` to either new model. No other code changes needed.
