# Bolna AI Updates for October, 2026

> October 2026 Bolna changelog: keyword biasing for Sarvam saaras:v4 speech-to-text.

<Update label="2nd October, 2026">
  ## Keyword biasing for Sarvam speech-to-text

  Sarvam's `saaras:v4` transcriber now reads your agent's `keywords`, so the brand names, places and product terms your Indian-language callers say are recognised instead of the nearest common word. Until now Sarvam took only `context`; on `saaras:v4` you can set both.

  * Add terms in the **Keywords** box in your agent's Languages tab, or pass `keywords` on the transcriber over the API
  * Up to 50 terms of up to 64 characters each, and a list over either limit is rejected when you save the agent
  * `saaras:v3` and older Sarvam models have no keyterm support, so the box stays disabled there; keywords already saved on the agent apply once you move it to `saaras:v4`
