Google Tests Hydrogen, a New Fast AI Model
Google is testing a new AI model called Hydrogen internally, built for speed and efficiency, and it is not yet known whether it will be free.
What is known about Hydrogen
Google is testing a new artificial intelligence model internally under the code name Hydrogen. It was built mainly for speed and efficiency.
Business Insider reports this based on internal documents and messages to Google employees. Staff who have already tried the model on the internal Jetski platform call it "very capable, fast and efficient."
How it compares to Flash and why the name
One employee compared Hydrogen with earlier models in the Flash line. Those models are usually fast, cheap workhorses, unlike more powerful but heavier models.
The name "Hydrogen" refers to the lightest element in the periodic table, which fits the focus on lightness and speed.
Will it be free
It is not yet known whether Hydrogen will be free if Google launches it publicly. Google already offers other Flash models to users for free, so this is possible, but it is only a guess.
Context: Gemini 4
The Hydrogen testing comes amid an update to the Gemini 4 family. Google previously released the Argon and Carbon models. According to the company, the flagship Gemini 4 Carbon shows the best results in cybersecurity and in long multi-step tasks.
Carbon and Argon are currently available only to paying users.
