Releasesby GlyphA 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.

BigQuery now supports TabFM , Google's pre-trained foundation model for tabular data
BigQuery now supports TabFM , Google's pre-trained foundation model for tabular data. TabFM enables zero-shot regression and classification through in-context learning. It delivers high-accuracy predictions on structured data without requiring model training or hyperparameter tuning.
You can now create an identity column , sometimes referred to as an auto-incrementing column, on a table
You can now create an identity column , sometimes referred to as an auto-incrementing column, on a table. You can use identity columns to create and maintain primary keys on your tables. When you insert a row into a table that has an identity column, BigQuery generates a unique integer value for that column. This feature is in Preview .
BigQuery Graph is generally available (GA)
BigQuery Graph is generally available (GA). BigQuery Graph now includes support for the CALL graph query statement , and the following path inspection GQL functions : IS_ACYCLIC IS_SIMPLE IS_TRAIL .
app.yml for Snowflake App Runtime (Preview)
Snowflake App Runtime projects use a single app.yml file to describe both deployment and the remote build. Include version: 2 at the top of the file. snow app setup writes this file for new projects.

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.
Create 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.

- Model selector in Gradium Studio : the Text-to-Speech page now has a Model dropdown to switch between the production model and gradium-tts-beta , showing each model_name with a copy button. Shareable studio links : pre-configure a session with ?voice= , ?model_name= , ?text= and ?language= and share the full setup as a single link.
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.
