WhatsApp has recently introduced a new feature called Chat Lock for users to make their intimate conversations even more private. The Meta-owned group enables its users to lock individual chats to enhance the security of their messages and protect their privacy.

If you don’t want someone to peep into the chat of a particular person then you can enable the Chat Lock feature as it allows an individual to lock that person’s chat with a password or biometric authentication.

The Chat Lock feature lets you protect your most intimate conversations with a password and secures them in a separate folder. When someone messages you and you have that chat locked, the sender’s name and the content of the message will also be hidden.

Along with this, when a WhatsApp chat is locked, that conversation thread is taken out of a user’s inbox, and put behind a folder of its own. It also automatically hides the contents of that chat in notifications.

As per Meta, the ability to lock a chat will be greatly beneficial for users who share their phones with family members from time to time.

How to enable WhatsApp Chat Lock feature?

  • Open WhatsApp on your Android or iOS smartphone and upgrade it to the latest version.
  • Click on that particular chat you want to lock in WhatsApp.
  • Select the contact or group by clicking on their profile photo.
  • You will see a Chat Lock option just below the message menu.
  • Set up Chat Lock, then use your phone’s password or biometrics to log in.

How to access locked chats on WhatsApp?

  • Open WhatsApp and navigate to your home page to view encrypted chat.
  • Swipe down to access all locked chats.
  • Select the locked chat by tapping on it.
  • Unlock the chat by entering your phone’s password or biometric data.

As per Meta, more options will be added to Chat Lock in the coming months, including locks for companion devices, as well as custom passwords for chats, so that a person can use a password different from that of their phone to unlock a conversation.

OpenAI launches GPT-6 Astra with major upgrades in AI reasoning, coding and computer use

OpenAI has introduced GPT-6 Astra, a new flagship AI model with advances in reasoning, coding, computer use, science and cybersecurity.

OpenAI has introduced GPT-6 Astra, a new flagship artificial intelligence model designed to handle complex reasoning, coding, computer-use tasks, scientific work and professional workflows.

The company describes Astra as its most intelligent and aligned model so far. According to OpenAI, the model combines advances in pre-training, reinforcement learning and alignment to improve its ability to perform multi-step tasks and work with computers and software.

GPT-6 Astra focuses on computer use and professional tasks

One of the key areas of improvement is computer use. OpenAI says GPT-6 Astra can perform tasks such as filling online forms, updating records, organising calendars and conducting online research.

The model can also analyse scientific data, generate plots, create websites and perform frontend quality checks. Its capabilities are intended to allow it to complete longer workflows rather than simply generate text in response to individual prompts.

OpenAI reported a 72.6% score on OSWorld 2.0, compared with 65.7% for GPT-5.6 Sol in the comparison provided by the company. It also reported a 59.3% score on Agents’ Last Exam and 92.7% on ScreenSpot-Pro.

GPT-6 Astra brings stronger coding capabilities

OpenAI says GPT-6 Astra is its strongest model for software engineering to date. The model is designed to work on complex coding tasks and can use tools to inspect software, execute code and test applications.

Astra also introduces improved context handling in Codex. According to OpenAI, the model can preserve and retrieve information from earlier context windows, helping it maintain requirements and test results during longer coding sessions.

Advances in science and mathematics

GPT-6 Astra has also been developed for scientific and mathematical applications. OpenAI says it achieved a 96% score on GPQA Diamond, a benchmark covering graduate-level questions in biology, chemistry and physics.

The company also reported a 99.9% score on ARC-AGI-3 and a 98% score on FrontierMath Tier 4. OpenAI further said Astra helped establish new results related to both unusually small and unusually large gaps between prime numbers.

These results are benchmark claims made by OpenAI and should not be interpreted as meaning that the model has achieved human-level intelligence across every area.

Cybersecurity capabilities also see a major jump

Cybersecurity is another area where Astra represents a substantial increase in capability. OpenAI says the model meets the Critical threshold for cybersecurity under its Preparedness Framework.

In the company’s testing, Astra achieved a 100% score on ExploitBench, compared with 78.5% for GPT-5.6 Sol. OpenAI also said the model discovered and used two previously unknown zero-day vulnerabilities during one evaluation and that the vulnerabilities were disclosed to their maintainers.

Because of these capabilities, OpenAI says additional safeguards have been introduced to reduce the risk of harmful cyber use.

GPT-6 Astra rollout and availability

OpenAI says GPT-6 Astra is initially rolling out to a limited group of organisations. The company plans to make it available over the following days to ChatGPT Plus, Pro, Business and Enterprise users.

The model is also being made available through the OpenAI API and AWS. Developers can access it through the API using the model identifier gpt-6-astra.

OpenAI’s API documentation lists a 1.05-million-token context window and a maximum output of 128,000 tokens for GPT-6 Astra.

Does GPT-6 Astra mean AGI has arrived?

The launch has renewed discussion around artificial general intelligence (AGI) because of Astra’s performance across a wide range of tasks. However, OpenAI’s official announcement describes GPT-6 Astra as a highly capable frontier model and does not state that the company has declared AGI achieved.

Therefore, it would be more accurate to describe Astra as a major advancement in AI capabilities rather than definitively calling its launch the arrival of AGI.

Vivo V80 Lite with 10,000mAh battery set for global launch on September 3

Vivo V80 Lite will launch in Malaysia on September 3 with a 10,000mAh battery, while its India launch and full specifications remain unconfirmed.

Vivo has confirmed that the V80 Lite will launch in Malaysia on September 3, with the smartphone’s 10,000mAh battery emerging as its biggest highlight. The company says the V80 Lite will be its first globally launched smartphone to feature a battery of this capacity.

The upcoming smartphone is expected to target buyers looking for long battery life, while its flat design and 50MP main camera will also be among its key features.

Vivo V80 Lite design and battery details

Vivo has revealed that the Malaysian version of the V80 Lite 5G will feature a flat frame and flat rear panel. The smartphone will be available in black, green and pink colour options.

At the back, the phone will have a square-shaped camera module housing a 50MP primary camera.

The 10,000mAh battery is the phone’s biggest talking point. While the V80 Lite is not Vivo’s first smartphone with a battery capacity of 10,000mAh or more, it is the company’s first globally launched model to reach this capacity. 

The Vivo Y600 Pro, which was launched in China, was the company’s first phone with a battery capacity of 10,000mAh or more.

Vivo V80 Lite specifications are still uncertain

The V80 Lite has previously appeared in certification databases under multiple model numbers. One of these, V2576, has also been associated with the Vivo S2, prompting speculation that the V80 Lite could reuse some hardware from that model in certain markets. 

Based on earlier reports, the V80 Lite could feature a 6.83-inch 1.5K AMOLED display with a 120Hz refresh rate. Other tipped specifications include a 50MP Sony IMX852 primary camera, an 8MP ultrawide camera and a 32MP front camera.

The phone is also tipped to feature Aura Light, stereo speakers, an in-display fingerprint sensor and IP68/IP69 protection. However, these specifications have not been fully confirmed by Vivo.

Chipset and charging details remain unclear

There is also uncertainty surrounding the V80 Lite’s chipset and charging capabilities. Earlier reports have pointed to both the MediaTek Dimensity 7360 Turbo and Dimensity 7300e.

Charging specifications are similarly unclear. While a 90W charging capability had previously been rumoured, certification information has pointed towards 44W charging.

The phone’s India launch has also not been confirmed yet. An earlier appearance on an Indian retailer’s Instagram page had suggested that the smartphone could eventually arrive in the country, although details of an India launch remain unavailable.

For now, Vivo has confirmed the Malaysia launch for September 3. More details about the V80 Lite’s complete specifications, pricing and availability are expected to emerge closer to the launch.

Uniform rules for WhatsApp, Telegram under review as Centre examines legal aspects

The Centre is reviewing responses from WhatsApp, Telegram and Zoho Bharat Eye over username-based messaging features, with a notification on uniform rules likely within 20 days.

The Centre is reviewing responses submitted by WhatsApp, Telegram and Zoho Bharat Eye regarding their username-based messaging features, as the government evaluates whether regulatory action is required. A notification on the issue could be issued within the next 20 days.

MeitY examines responses from messaging platforms

According to sources in the Ministry of Electronics and Information Technology (MeitY), WhatsApp, Telegram and Zoho Bharat Eye have responded to government notices concerning username-based messaging features.

The ministry’s legal team is scrutinising the replies to determine whether any existing legal provisions have been violated and whether any clauses can be invoked for regulatory action or sanctions.

Speaking on the sidelines of the launch of a cybersecurity report on Monday, MeitY Secretary S. Krishnan confirmed that WhatsApp’s response had been received over the weekend and is currently under examination.

“The reply was received last week. We are examining the response and action, if any, will be taken after that examination,” he said.

Government stresses uniform regulatory approach

The government has maintained that any regulatory framework introduced in connection with username-based messaging will apply equally across all messaging platforms rather than targeting any single service.

Union Minister Ashwini Vaishnaw has indicated that a notification on the matter is expected within the next 20 days. The ongoing review is focused on examining the legal implications rather than being a purely policy exercise.

Why the government raised concerns

MeitY had issued notices to WhatsApp, Telegram and Signal after expressing concerns that username-based messaging, which allows users to communicate without sharing their phone numbers, could be misused for impersonation, phishing, identity theft and so-called “digital arrest” scams.

Earlier, a WhatsApp spokesperson said the platform is primarily designed as a private messaging service that helps people stay connected with friends and family.

The review forms part of the government’s broader efforts to strengthen online safety, curb the misuse of digital communication platforms and ensure that any future regulations are implemented uniformly across messaging services.
