When Google released Gemini 3 Pro at the end of last year, it was a significant step forward for the company's proprietary large language models. Now, the company is bringing some of the same technology and research that made those models possible to the open source community with the release of its new family of Gemma 4 open-weight models.
Google is offering four different versions of Gemma 4, differentiated by the number of parameters on offer. For edge devices, including smartphones, the company has the 2-billion and 4-billion "Effective" models. For more powerful machines, there's the 26-billion "Mixture of Experts" and 31-billion "Dense" systems. For the unfamiliar, parameters are the settings a large language model can tweak to generate an output. Typically, models with more parameters will deliver better answers than ones with less, but running them also requires more powerful hardware.
With Gemma 4, Google claims it's managed to engineer systems with "an unprecedented level of intelligence-per-parameter." To back up this claim, the company points to the performance of Gemma 4's 31-billion and 26-billion variants, which claimed the third and sixth spots respectively on Arena AI's text leaderboard, beating out models 20 times their size.
All of the models can process video and images, making them ideal for tasks like optical character recognition. The two smaller models are also capable of processing audio inputs and understanding speech. Separately, Google says the Gemma 4 family is capable of generating offline code, meaning you could use them to do vibe coding without an internet connection. Google has also trained the models in more than 140 languages.

SpaceX has reportedly taken the step many onlookers have long expected: filing paperwork to hold an initial public offering (IPO) on the stock market and become a publicly traded company. Rumors had long pointed toward the IPO taking place by July.
The company filed draft IPO registration paperwork with the US Securities and Exchange Commission confidentially, according to Bloomberg. As such, the public won't get a chance to closely scrutinize SpaceX's finances just yet. Taking the confidential approach means SpaceX can obtain feedback from the SEC before making the details public and announcing key factors like the price range and number of shares it's planning to sell at the outset.
SpaceX is said to have designs on holding the largest IPO in history. It's reportedly looking to raise $75 billion in the offering, which would far exceed the current record held by Saudi Aramco, which pulled in $24 billion in its 2019 IPO.
It's expected that SpaceX will seek an IPO valuation of $1.75 trillion. When the Elon Musk-led business swallowed up the Elon Musk-led xAI earlier this year (which means SpaceX is now the parent of X and Grok), the entire company was valued at $1.25 trillion.
SpaceX is reportedly planning to use the funds it brings in from its IPO to turbocharge its various ambitions, including its
