Releasesby GlyphCreate a voice from a written description, no audio sample needed
Create a voice from a written description, no audio sample needed. Describe the accent, age and character you need, generate up to five candidates, and keep your favourite. The voice works with the same Text-to-Speech endpoint as any catalogue voice. In our blind listening evaluation, native speakers judged how well voices matched accent prompts.

Add and drop hybrid table constraints online (General availability)
With this release, you can add and drop UNIQUE and FOREIGN KEY constraints on an existing hybrid table by using alter table . Previously, you had to define these constraints when you created the table, so adding a foreign key to a table that was already serving a workload meant recreating and reloading the table.
Shadow traffic for gateways (Preview)
With this preview release, you can use a shadow traffic gateway to send all production requests to a primary service endpoint while mirroring a percentage of those requests to one or more shadow endpoints. Responses from shadow endpoints aren't returned to clients.
The partner-powered AI features setting will be removed
On November 1, 2026, Databricks will remove the account- and workspace-level toggle for partner-powered AI features. Each workspace will keep its current setting value: if the setting is enabled, it stays enabled, and if it's disabled, it stays disabled. Removing the toggle doesn't change any setting values.
Incremental ingestion for Salesforce formula fields in Lakeflow Connect will soon be generally available
Incremental ingestion for Salesforce formula fields in Lakeflow Connect will soon be generally available. Today, Lakeflow Connect ingests formula fields by taking a full snapshot on each pipeline run by default. When incremental formula field ingestion is generally available, full snapshots will no longer be the default.

A new Gradium Text-to-Speech model is live and is now the default
A new Gradium Text-to-Speech model is live and is now the default. Existing voices, including custom voices, work as-is. The model reads the structured entities that break voice agents in production, such as phone numbers, email addresses, IBANs and reference codes, with no pre-processing or text normalization needed.
Our new Text-to-Speech model entered public beta with lower latency and more expressive speech
Our new Text-to-Speech model is available in public beta, with lower latency and more expressive speech. In our latest measurements, the beta reaches time to first audio in under 50 ms, against 225 ms for the production model. Latency varies with network conditions and input. Set model_name to "gradium-tts-beta" in your TTS setup to use the beta.
Speech-to-Text requests now require a language in json_config
Speech-to-Text requests now require a language in json_config . Our ASR gives its best results when the language is known, so set it whenever you can: en , fr , es , pt , or de . When the language is not known ahead of time, pass any and the model detects it from the audio. Requests that already set a language or any are unaffected.
Clean up a voice you already have without changing its language or who is speaking
Clean up a voice you already have without changing its language or who is speaking. POST /voice-generator/enhance takes a flagship voice, a clone or a candidate and returns candidates with background noise reduced. Audition and convert them like Voice Design candidates. Voice Enhance is in beta; output quality will keep improving.
Our new Text-to-Speech model is now the default, with more expressive speech and lower latency
Our new Text-to-Speech model is now the default, with more expressive speech and lower latency. Existing requests using default use the new model without a setup change. gradium-tts-beta also routes to this model until the next TTS beta arrives. Keep that alias to follow future betas, or use default to stay on stable releases.
