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.

 The latest iteration of Meta's smart glasses has arrived and, as rumored, they are more customizable, particularly for people who need prescription lenses. Meta and Ray-Ban parent company EssilorLuxottica revealed two new styles of frames: the Ray-Ban Meta Blayzer Optics and Scriber Optics, which will start at $499 a pair.
The latest glasses are still considered to be part of the "Gen 2" Ray-Ban Meta glasses, but they do come with a few upgrades that make it easier to get a personalized fit. According to EssilorLuxottica, both styles have somewhat slimmer frames, swappable nosepads and adjustable temple tips so wearers can get a better fit. And, as the "optics" branding implies, the new frame styles are also compatible with a wider variety of prescription lenses, including progressive lenses and transition lenses.
The Blayzer style frames are more square, similar to the existing Wayfarer glasses, while the Scriber version is a little more rounded, like the "Headliner" style frames. Both come in a variety of colors including some translucent styles and are available now for pre-order on Meta's website and will be on sale April 14. The "optics" lineup will also be sold at more physical retail stores, including LensCrafters, Sunglass Hut, Salmoiraghi & Viganò, Apollo, Grand Vision Optical, Vision Express and other locations that are part of EssilorLuxottica's distribution network.
The round, "Scriber" frames.
