Google Gemma 4 Puts Offline AI on Phones, but New Reviews Say It Won’t Kill ChatGPT Yet

  • New user feedback points to Google’s Gemma 4 boosting offline AI’s practicality on both phones and laptops, with a focus on affordable and privacy-focused jobs.
  • Google is rolling out the model via AI Edge Gallery, Android Studio, and an AICore preview in Android, aiming to shift more AI workloads onto devices.
  • Reviewers note that when it comes to speed, memory, and more demanding tasks, cloud-based players like ChatGPT, Gemini, and Claude continue to have the upper hand.

Over the past two days, a string of hands-on reviews has started to put Google’s Gemma 4 through its paces with everyday users — and the verdict is lining up: offline AI on personal devices is edging closer to practical utility. Outlets like XDA Developers, Tom’s Guide, Android Police, and Geeky Gadgets all circled the same appeal: Gemma 4 works without an internet connection, keeping your prompts away from the cloud.

The distinction is suddenly important: so far, consumer AI’s been ruled by cloud-based apps like ChatGPT, Gemini and Claude—sleek, responsive, but all handling requests in distant data centers. Now Google is pushing Gemma 4, an open-weight model. That’s a shift; developers can grab the model, run it locally, and skip the cloud, thanks to its Apache 2.0 license. The model targets phones, PCs, and edge devices.

On April 2, Google introduced its Gemma 4 lineup, which includes four models: E2B and E4B, aimed at lighter hardware, along with the 26B MoE and 31B models built for more powerful systems. MoE—short for mixture of experts—lets only portions of the model run at once, reducing how much memory is needed. According to Google, as of April 1, the 31B model held the No. 3 spot among open models on Arena AI’s text leaderboard, with the 26B coming in at No. 6. The Gemma 4 family spans support for over 140 languages.

Google is weaving the software directly into Android as well. Matthew McCullough, Android’s VP of product management, said Gemma 4 forms the backbone for the coming generation of Gemini Nano on Android. According to McCullough, it delivers “up to 4x faster” speeds and cuts battery use by “up to 60%” compared to the last version.

Initial feedback on phones has been cautiously upbeat, if a bit limited. Amanda Caswell at Tom’s Guide noted that after a day with Google’s AI Edge Gallery, the app ran just fine in Airplane Mode and stored data locally. Still, she found it no match for ChatGPT when it came to serious research, quick responses, or remembering past conversations. Caswell’s test of the suggested Gemma 4 E2B model showed it needed around 2.5 GB of storage.

Coverage from other outlets followed a similar line. Parth Shah at Android Police recommended Pixel owners give the free tool a shot. XDA Developers didn’t name Gemma 4 the sharpest local model, but called the 26B mixture-of-experts version “the one I reach for most.” Geeky Gadgets picked up on the ability to work offline, highlighting local visual analysis, offline docs, and no subscription needed.

Google’s pitch to developers leans harder than its consumer play. AI Edge Gallery has added Agent Skills on both iOS and Android, allowing multi-step tasks to happen right on the device. Over in Android Studio, Gemma 4 is now in the mix for local coding help. Or as Google product manager Matthew Warner summed it up: “Your code stays on your machine.” Google Developers Blog

The field’s divided. For consumers, Gemma 4 faces off with OpenAI’s ChatGPT, Google’s cloud-based Gemini, and also Anthropic’s Claude. On the tools side, Google is marketing Gemma 4 as a more affordable, privacy-minded pick for certain coding and workflow needs—jobs that might otherwise go through paid APIs or subscription services.

Chirag Dekate, vice president analyst at Gartner, sees a false choice in the open vs. proprietary AI debate. “Agility matters more than dogmas,” Dekate said. His advice for CIOs: assemble a portfolio blending open models and proprietary tools, with the mix shaped by workload and the necessary guardrails. CIO Dive

Still, the local-first approach isn’t without drawbacks. According to Google, true mobile performance hinges on devices equipped with AICore—otherwise, users might see slower, CPU-based responses that don’t reflect finished production speeds. Tom’s Guide reported that replies lagged behind cloud-based chatbots. Dekate also flagged issues: open models often offer less robust safety controls, and there’s no guarantee a model family will remain open in the future.

Put simply, the recent reviews don’t indicate that local AI is on the verge of taking over from ChatGPT. What’s actually emerging is a more limited use case: handling private queries, helping out with coding projects on the device, automating small tasks, or filling in when there’s limited internet access or strict privacy needs. Should Google manage broader device compatibility and iron out some of Gemma 4’s quirks, the model could end up being less about outcompeting chatbots and more about powering Android’s next AI layer under the hood.

  • CSL (ASX: CSL) shares edge up over 10 years, but pandemic and Vifor deal weigh
    July 15, 2026, 3:59 PM EDT. CSL Ltd (ASX: CSL) shares ended the past decade up just 2%, closing at about A$121.75 after starting 2014 near A$119. With dividends of around A$30.57 per share, shareholders got a 28% return. The stock fell hard from a 2021 high near A$315, hit by COVID-related plasma supply problems, higher costs, and letdowns around the Vifor buy and lower vaccine sales. Some investors now doubt CSL's growth outlook. Still, CSL holds major healthcare assets and strong science teams, so a rebound is possible if earnings and cost pressures settle. The market is now valuing CSL below its former high-growth run on the ASX.
