Google's new Gemma 4 12B model is designed to run on any laptop with 16GB of RAM

By Ryan Whitwam

AI Analysis

Google added a 12B model to its Gemma 4 family, filling the gap between the small mobile variants and the larger 26B/31B models. It is efficient enough to run on a consumer laptop with 16GB of RAM under an Apache 2.0 license.

The generative AI boom has driven the cost of memory into the stratosphere, and Google is a key part of that trend. So it's only fitting that Google should offer some less RAM-hungry local AI models. The company has announced the release of a new Gemma 4 model that fills a gap in the lineup that launched earlier this year. The new model is efficient enough that you may be able to run it on a pretty average consumer laptop. In April, Google released four models in the Gemma 4 family, which also m

Trump plan to test AI models has a problem—US security teams were gutted by DOGE

By Ashley Belanger

55 score
AI Analysis

Critics warn that Trump's new executive order on voluntary frontier AI safety testing is largely performative because US security teams responsible for such evaluations were gutted by DOGE cuts. The order changes little about how or when models are deployed.

On Tuesday, Donald Trump finally signed his executive order expanding the government's efforts to conduct voluntary safety testing of frontier AI models. Now, critics are warning that the order may be short-sighted, offering only performative reassurances that the government is actively monitoring for AI risks, while changing very little about how and when models are deployed. Last month, Trump abruptly canceled a signing event, where he had hoped to launch an earlier version of the EO with CEOs
