AI Chip Startup Cerebras Releases Open Source ChatGPT-Like Models for Free: All Details

Artificial intelligence chip startup Cerebras Systems on Tuesday said it released open source ChatGPT-like models for the research and business community to use for free in an effort to foster more collaboration.

Silicon Valley-based Cerebras released seven models all trained on its AI supercomputer called Andromeda, including smaller 111 million parameter language models to a larger 13 billion parameter model.

"There is a big movement to close what has been open-sourced in AI...it's not surprising as there's now huge money in it," said Andrew Feldman, founder, and CEO of Cerebras. "The excitement in the community, the progress we've made, has been in large part because it's been so open."

Models with more parameters are able to perform more complex generative functions.

OpenAI's chatbot ChatGPT launched late last year, for example, has 175 billion parameters and can produce poetry and research, which has helped draw large interest and funding to AI more broadly.

Cerebras said the smaller models can be deployed on phones or smart speakers while the bigger ones run on PCs or servers, although complex tasks like large passage summarization require larger models.

However, Karl Freund, a chip consultant at Cambrian AI, said bigger is not always better.

"There's been some interesting papers published that show that (a smaller model) can be accurate if you train it more," said Freund. "So there's a trade off between bigger and better trained."

Feldman said his biggest model took a little over a week to train, work that can typically take several months, thanks to the architecture of the Cerebras system, which includes a chip the size of a dinner plate built for AI training.

Most of the AI models today are trained on Nvidia's chips, but more and more startups like Cerebras are trying to take share in that market.

The models trained on Cerebras machines can also be used on Nvidia systems for further training or customization, said Feldman.

The Last of Us Part I’s PC Port in Bad Technical Shape, Developer Investigating Performance Issues

The Last of Us Part I was finally released on PC on Tuesday, March 28, and it's already getting bombarded with negative Steam reviews. At the time of writing, the game has a 33 percent positive rating, mainly owing to the broken state it was released in. Since its launch, there have been multiple reports in regard to performance issues, ranging from hard crashes, stuttering, poor optimisation, and long loading times. Developer Naughty Dog remade its 2013 magnum opus for the PS5 last year and originally planned on porting it to PC on March 3. However, it was then delayed to March 28, in light of ensuring that the game debuts in ‘the best shape possible'. Sadly, things don't seem to have gone according to plan.

In a tweet, Naughty Dog confirmed that it's ‘actively investigating' the issues. “We will continue to update you, but our team is prioritizing updates and will address issues in upcoming patches,” it reads. Prior to its launch, it seems that media outlets and content creators have not been provided with a press copy for The Last of Us Part I PC, which is quite unusual for Sony, as it has consistently sent review codes days — and sometimes, weeks in advance.

This time, developer Iron Galaxy was entrusted with the job of porting the game over to PC — the same group which was responsible for Batman: Arkham Knight's disappointing PC port back in 2015. While it did a decent enough job with Uncharted: Legacy of Thieves Collection in 2022, TLOU's port seems to have been rushed out.

The Last of Us Part I PC System Requirements and Features Revealed

Gadgets 360 can confirm player reports regarding the game's ‘Shader Building' process, which in addition to being time-consuming, was causing random freezes. The Last of Us Part I's PC settings lean more toward CPU usage leading to micro stutters, while the graphics memory easily maxes out at medium settings. Players have also been reporting game crashes while idling in the main menu as they wait for shaders to build, in addition to encountering loading screens during cutscenes in-game.

“Pre-purchased & pre-loaded. Launched it as soon as it was ready. Went to the settings. Turns out this game is eating up nearly 10GB of VRAM at 1440p max settings (game defaulted the settings to maximum),” a Steam user wrote. “I'm running an RTX 3080 Ti with 12GB VRAM, mind you. Never could get past the menu screen which always crashes when the game displays a notification at the bottom right corner that reads ‘BUILDING SHADERS'.”

Players on the Steam Deck have been reporting issues as well — claiming that shaders are taking at least an hour to build, whilst running at 30fps on measly Low–Medium graphics settings. Bear in mind, Steam only allows for two hours of play time, before which you can request a refund. Poor game optimisation has been a common issue for PC gamers lately — Gotham Knights and the more recently-released Wo Long: Fallen Dynasty are great examples of that, running with micro stutters even at the lowest settings. Even Hogwarts Legacy on PC requires dedicated time to build shaders upon every launch, albeit the optimisation isn't as bad.

The Last of Us Part I is now available on PC via Steam and Epic Games Store. That said, I don't recommend that you purchase it until performance patches are released.

Alibaba to Split Into 6 Units as China Vows to Ease Crackdown on Private Sector

Alibaba Group is planning to split into six units and explore fundraisings or listings for most of them, it said on Tuesday, in a major revamp as China vows to ease a sweeping regulatory crackdown and support its private enterprises.

The US-listed shares of the Chinese e-commerce conglomerate, which have lost nearly 70 percent of their value since the curbs were imposed in late 2020, rose more than 10 percent.

Alibaba said the biggest restructuring in its 24-year history would see it split into six units - Cloud Intelligence Group, Taobao Tmall Commerce Group, Local Services Group, Cainiao Smart Logistics Group, Global Digital Commerce Group and Digital Media and Entertainment Group.

The revamp comes a day after Alibaba founder Jack Ma returned home from a year-long stay abroad, a move that dovetailed with Beijing's effort to spur growth in the private sector after two years of crackdown.

Analysts said the breakup could ease scrutiny over the tech giant whose sprawling business has been a target of regulators for years.

"The original intention and fundamental purpose of this reform is to make our organisation more agile, shorten decision-making links and respond faster," Chief Executive Daniel Zhang said in a letter to staff, which was seen by Reuters.

Each business group, he said, had to tackle the rapid changes in the market and each Alibaba employee had to "return to the mindset of an entrepreneur".

Zhang will continue as chairman and CEO of Alibaba Group, which will follow a holding company management model, and also serve as CEO of Cloud Intelligence Group.

Each of the six businesses will have a CEO as well as a board of directors and will retain the flexibility to raise outside capital and seek an initial public offering, the company said.

The exception would be Taobao Tmall Commerce Group that handles China commerce businesses and will remain a wholly owned unit of Alibaba Group.

The company would "lighten and thin" its middle and back office functions, Zhang said, but did not detail job cuts.

Investors said the split signals the clearing of regulatory worries and allays concerns that Alibaba had lost the potential to grow.

The decision could also be partly a fallout of the US scrutiny of Chinese tech firms that raised national security concerns over TikTok and its parent ByteDance, said Tara Hariharan of emerging market hedge fund NWI Management.

"By paving the way for Alibaba's various new units to list, the Chinese government may be signalling less hostility towards its tech giants as a placatory message to US and international investors," said Hariharan, managing director of global macro research.

Ma's return

The restructuring is among the biggest corporate moves by a major Chinese tech company in recent years, as the industry cowered under tighter regulatory oversight, causing deals to dry up and dampening risk appetite among businesses.

Lately, authorities have been softening their tone towards the private sector as leaders try to shore up an economy battered by three years of strict COVID-19 curbs.

Companies, however, have been hesitant, privately pointing to a lack of new supportive policies and the new regulatory framework.

Alibaba's shares had received a boost on Monday after founder Ma returned to China as his overseas stay was viewed by the industry as a reflection of the sober mood of its private businesses.

China's new premier, Li Qiang, had recognised Ma's return to the mainland could help boost business confidence among entrepreneurs and since late last year had begun asking him to come back, five sources with knowledge of the matter told Reuters.

"It does seem something of a coincidence that this is happening just as Ma seems comfortable returning. To me it suggests something that Alibaba has been wanting to do for some time, but has been waiting for the opportunity," said Stuart Cole, head macro economist at brokerage Equiti Capital.

The restructuring "does inject an element of flexibility and adaptability into the company, which currently is something of a behemoth," he said.

Central Government IT System to Support Email Communications in Hindi Scripts in Two Years

All IT systems in the central government will start supporting email communications in Hindi scripts in the next two years, a senior official said on Monday.

While speaking at the Universal Acceptance (UA) Day curtain raiser event, Ministry of Electronics and IT Additional Secretary Bhuvnesh Kumar said that the work has started to make 15 ministry's websites UA-compliant and content on them is being made available in Hindi.

"Resolver to facilitate e-mail communications in local language script will be done over a period of 2 years. Initially, it will support Hindi script and later other languages will be added," Kumar said.

He said that the Centre is encouraging the state governments to provide content in the local languages.

Global Internet body ICANN has been supporting Universal Acceptance that aims to address issues around language barriers that check people from connecting to the Internet.

The Internet has been dominated by the English language which prevents several non-English speaking individuals from using it.

The concept of UA is to develop technology to facilitate communications in native scripts on the Internet like Bengali, Devanagari, Gujarati, Gurmukhi, Kannada, Malayalam, Oriya, Tamil and Telugu.

ICANN, VP, Stakeholder Engagement, and Managing Director for Asia Pacific Jia-Rong Low said at the event that big technology companies like Google, and Microsoft have come on board to support UA and there is a need for local companies to adopt it as they are closer to the users.

State-owned National Internet Exchange of India (NIXI) CEO A K Jain said that people can now book domain name in all Indian language scripts and the Centre has started to adopt them.

Samsung Working on a Fix to Address Camera App Crashes on Select Galaxy S Series Models: Report

Samsung has been providing hybrid and optical zoom capabilities on its Galaxy S series smartphones for a while. However, a new bug seems to trigger an app crash when a user sets the camera's zoom to 30X. The bug only seems to affect a certain set of Samsung Galaxy S series devices according to a report. Samsung has acknowledged that the camera bug is an issue and that it is working on a fix for the same. The company claims that the fix will arrive in a future software update.

Just a few days ago, a Samsung user who owns a Galaxy S series device posted on Samsung's Korea community forum about a camera bug that gets triggered when setting the camera's zoom to 30X in the stock camera app. The user claims that the camera app's zoom functionality works fine until 28.8x, but crashes as soon as the 30X zoom level is selected. The user mentions that clearing the app's cache and data and resetting it to its default settings also does not seem to resolve the issue.

The user also posted a video showing the camera bug. The video shows Samsung's default camera app in action with the user scrubbing through the zoom slider till about 30X, post which the app crashes. Another point that the user clarified was that the camera bug only showed up after updating the Galaxy S series device to Samsung's latest One UI 5.1 update, which is based on Android 13. So, those who haven't upgraded their Galaxy smartphones to the latest One UI software may not experience the same camera bug.

SamMobile was the first to report the issue and claimed that the camera bug could only affect recent models of the Galaxy S series. This would include the Galaxy S20, Galaxy S21, and Galaxy S22 series of devices as these are the only ones to offer 30X zoom capability. Gadgets 360 can confirm that the camera bug does not affect the latest Samsung Galaxy S23 and Galaxy S23 Ultra models.

Regardless of which smartphones are affected, Samsung has mentioned in its replies that it has managed to reproduce the issue. The company claims that the “error occurred due to the difference in the action point when quickly switching the camera lens” and that it has already applied the necessary fixes to an upcoming software update. This software update will be made available in April. However, Samsung has not provided any specific details about the exact day on which the software update will arrive.

Apple Rolls Out iOS 16.4 Update With New Emojis, Voice Isolation for Calls, More: Details

Apple has released iOS 16.4 for iPhone users, which incorporates a number of new features such as an extensive set of emojis, voice isolation for calls, website push notifications, and more. Alongside the iOS update, Apple has released the iPadOS 16.4 update for iPad. The company also released tvOS 16.4 and macOS Ventura 13.3. The stable version of iOS 16.4 is now rolling out for iPhone users across the globe.

Users can update their devices by going to the Settings app, selecting General, and then Software Update. If they don't see the update immediately, keep checking periodically as the updates should be available for everyone soon. When the installation process starts, the iPhone or iPad will download the update and then prompt the user to restart the device to complete the process. It is worth noting that the device will be inoperable while the update is being installed.

Those in Apple's developer programme can now enable the developer beta option instantly from the Software Update section by going to Settings > General > Software Update > Beta Updates and selecting the developer beta. Instead of having to install a profile from the Developer Center, this is a quick way to receive the stable developer beta version. However, because you will need to be signed in to an Apple ID linked to a developer account, public sharing of developer beta profiles will be discontinued.

The changelog for the iOS 16.4 update includes 21 new emojis including a shaking face, a pink heart that has been demanded for long, two pushing hands, a Wi-Fi symbol and others, including various animals and objects. These emojis were approved by the Unicode Consortium last year, and it was confirmed in February that they would be included in the latest iOS update. There are also grey and light blue hearts, a folding hand fan, ginger, a pea pod, jellyfish, a moose, a goose, a hair pick, maracas, a flute, and other emojis in the new batch.

Another feature added with this update is voice isolation for cellular calls, which prioritises users' voices while blocking out ambient sound. The feature was already usable for FaceTime as well as other VoIP apps, but not for cellular calls until now. To access this feature, open the Control Center while on the call, tap on Mic Mode, and then from the list available, select Voice Isolation.

Apple demonstrated a feature last year at the Worldwide Developers Conference (WWDC) that permitted developers to send web-based push notifications to target consumers. With an update to macOS Ventura, the company previously added this feature to Safari 16.1. It now allows iOS developers to send a notification to users who have pinned a web application to their Home Screen after requesting permission.

This web application update could be directly applicable to some of Twitter's new rivals, such as Post and T2, who have not yet developed native iOS editions of their apps yet, but would like to notify the user of important discussions. This also allows Apple to mitigate assertions that its App Store serves as the sole way to connect with mobile consumers, which might aid in the company's fight against antitrust regulations and other litigation.

Apple's new iOS 16.4 update also fixes bugs regarding duplicated album in Photos and also brings support to detect duplicate photos or videos in an iCloud Shared Library. The Weather app now gets VoiceOver support for maps. Moreover, a new accessibility setting can automatically dim video when flashes of light or strobe effects are seen.

The iPhone keyboard now supports indigenous languages like Chickasaw and Choctaw and Apple has also added support for transliteration for Gujarati, Punjabi, and Urdu language keyboards.

Finally, the update also fixes an issue where previously Ask to Buy requests from children would often fail to appear on the parent's device. It addresses an issue where Matter-compatible thermostats may become unresponsive when connected to Apple Home devices. The iOS 16.4 update also comes with Crash Detection optimisations on iPhone 14 and iPhone 14 Pro, iPhone 14 Plus, and iPhone 14 Pro Max.

Nvidia's New Research Shows How AI Can Be Used to Improve Chip Design

Nvidia, the world's leading designer of computer chips used in creating artificial intelligence, on Monday showed new research that explains how AI can be used to improve chip design.

The process of designing a chip involves deciding where to place tens of billions of tiny on-off switches called transistors on a piece of silicon to create working chips. The exact placement of those transistors has a big impact on the chip's cost, speed and power consumption.

Chip design engineers use complex design software from firms like Synopsys and Cadence Design Systems to help them optimise the placement of those transistors.

On Monday, Nvidia released a paper showing that it could use a combination of artificial intelligence techniques to find better ways to place big groups of transistors. The paper aimed to improve on a 2021 paper by Alphabet's Google, whose findings later became the subject of controversy.

The Nvidia research took an existing effort developed by University of Texas researchers using what is called reinforcement learning and added a second layer of artificial intelligence on top of it to get even better results.

Nvidia chief scientist Bill Dally said the work is important because chip manufacturing improvements are slowing with per-transistor costs in new generations of chip manufacturing technology now higher than previous generations.

That goes against the famous prediction by Intel co-founder Gordon Moore that chips would always get cheaper and faster.

"You're no longer actually getting an economy from that scaling," Dally said. "To continue to move forward and to deliver more value to customers, we can't get it from cheaper transistors. We have to get it by being more clever on the design."
