Mobile phones are the most ubiquitous end devices, generating vast amounts of human-authored data and serving as the primary platform for end-side applications. As high-quality public data for large language models (LLMs) approaches exhaustion, on-device fine-tuning provides an opportunity to leverage private user data while preserving privacy. However, existing approaches are predominantly simulation-based or rely on IoT devices and PCs, leaving commodity mobile phones largely unexplored. A key gap is the absence of an open-source framework that enables practical LLM fine-tuning on mobile phones. We present MobileFineTuner, a unified open-source framework that enables end-to-end LLM fine-tuning directly on commodity mobile phones. MobileFineTuner is designed for efficiency, scalability, and usability, supporting full-parameters fine-tuning (Full-FT) and parameter-efficient fine-tuning (PEFT). To address the memory and energy limitations inherent to mobile phones, we introduce system-level optimizations including parameter sharding, gradient accumulation, and energy-aware computation scheduling. We demonstrate the practicality of MobileFineTuner by fine-tuning GPT-2, Gemma 3, and Qwen 2.5 on real mobile phones. Extensive experiments and ablation studies validate the effectiveness of the proposed optimizations and establish MobileFineTuner as a viable foundation for future research on on-device LLM training.

Google usually reveals a new Pixel smartphone in the autumn – but this year it seems to be wasting no time to get ahead of the curve. The tech giant has confirmed that its annual'Made by Google' unveiling event will take place on August 13, where it will showcase new devices and software. It's expected to announce the latest smartphone in its Pixel line, the Pixel 9, which could be packed with a range of new AI features to rival Apple. The event may even launch a successor to its first foldable phone, the Pixel Fold that was released last year for an eyewatering 1,749. A brief teaser video contains the Google Pixel branding and the number nine in Roman numerals – referring to the ninth phone in the series. Google's teaser video shows the outline of a smartphone with 9 in Roman numerals - a clear indication it's preparing the new hotly-anticpated device The video, entitled'AI... meet IX at Made by Google', confirms the date of the event in Roman numerals – VIII-XIII-MMXXIV, or August 13, 2024.

Google is trying anything it can to stand out with its smartphone, which looks more and more like an iPhone. Its latest handset taps into AI-powered photography to make taking photos easier and allow people to manipulate an image to make it look better. The Google Pixel 8 is the latest smartphone from Google. The Pixel 7 was released in 2022. The Pixel 8 has a smoother 120Hz OLED panel that gets significantly brighter, faster hardware that's ideal for gaming, and a larger battery that should last all day.

Since the original Pixel, the special sauce for all of Google's phones has been its software. We've seen this throughout the years in its cameras with things like HDR processing and Google's potent Night Sight mode. But on the Pixel 8 and Pixel 8 Pro, thanks to the new Tensor G3 chip and focus on machine learning, it feels like Google's latest flagship phones are taking some of the buzz from the recent AI hype cycle and turning it into tools you'll actually want to use. Their corners are a touch more rounded and Google deleted the small chin below the screen by making its bezels a uniform size all around. One notable change is that the Pixel 8 has shrunk a bit to a 6.2-inch screen (down from 6.3 inches on the Pixel 7).

After teasing us for weeks with trailers showing off the Pixel 8 series, Google is now ready to give us all the details about its latest flagships. The Pixel 8 and Pixel 8 Pro look largely the same as their predecessors, with a couple of key differences. The regular Pixel 8 is slightly smaller, which makes it easier to use with one hand. Meanwhile, the Pro model has a new matte finish, upgraded cameras and an intriguing temperature sensor. So, you might actually be able to hang on to your Pixel flagship for a lot longer than before.

Google's October hardware event took place this morning in New York City. During its presentation, the company showed off three new pieces of hardware: the Pixel 8 and Pixel 8 Pro smartphones, and the Pixel Watch 2. The new phones are flush with new features, from secure face authentication and seven years of software support to a built-in thermometer, while the second-generation Pixel Watch has more modest improvements over its predecessor. There are also some software upgrades coming to the Pixel Buds Pro, Google's wireless earbuds. You can read more about that in a separate story. Below is everything you need to know about the Pixel 8 series phones and Pixel Watch 2. If you buy something using links in our stories, we may earn a commission.

Google's big developer conference had a lot to get through. That included the Pixel Fold (more on that below), a new Pixel A-series phone for only $500, a tablet, Android 14, a faster, more sophisticated AI language model, and lots more tricks for AI chatbot Bard. Coming soon, Bard will be able to analyze images and integrate into Google apps, like Gmail and GDocs. And if you haven't dabbled with Bard yet – no more waiting list. And while Google had media and analysts captive, it showed off its holographic meeting experience, Project Starline, two years after it first appeared.

To say the Google I/O 2023 keynote was packed would be an understatement. Google unveiled a flurry of new Pixel devices as well as the latest versions of Android and other platforms. It also won't surprise you to hear that AI was everywhere -- this was Google's big chance to compete with OpenAI's ChatGPT. Don't worry if you missed something during the event, though, as we've got all the biggest announcements from the event. There's no doubt that the (previously confirmed) Pixel Fold was the star of the show.

The cut-off dates for holiday shopping have mostly passed, but that doesn't mean the deals have disappeared. We're seeing prices that match Black Friday, like the Beats Fit Pro for just $160 and Bose's QuietComfort Earbuds II for $249. Some items have even dipped below their Cyber Week prices, like GoPro's Hero 11 Black Mini, the 13.3-inch MacBook Pro and Eufy's RoboVac X8 Hybrid. While these items may not ship out in time to wrap them up as gifts, this is still a great opportunity to grab devices and tech you've had your eye on, and save a little in the process. Here are the best deals from the week that you can still get today.

Google is releasing its latest round of Pixel updates today, including the free VPN the company teased at its October event. Clear Calling also launches to the public alongside updates for its voice memo app and new sleep features for the Pixel Watch. Pixel 7 and Pixel 7 Pro users can now use the Google One VPN on their phones for free (rather than buying it bundled with a $10-per-month storage plan). Clear Calling, Google's voice isolation for calls which had been in beta since October, is now available for all Pixel 7 series owners. The AI-powered feature makes calls in noisy environments sound better by bringing your voice to the forefront while drowning out background noise. Recorder, Google's AI-based voice memo app, now transcribes and organizes recordings for multiple people.
