Airmega Mighty AP-1512HH

Despite its low price tag and squat stature, the Airmega Mighty is capable of cleaning a substantial amount of space. At full bore, it can handle a 361-square-foot space, although you’ll get the best performance, and save your ears, if you’re closer to a 200-square-foot room. If you don’t want it running constantly, there are built-in timers to automatically shut off after 1, 4, or 8 hours, or you can use Eco Mode, which will run until the Might doesn’t sense any dirty air for half an hour.

That’s right, the Airmega Mighty has a built-in air quality sensor, and it reflects the current state of the air quality using a colored light with three levels. It uses those readings to automatically adjust the fan speed and timing settings on the fly, as well as giving you a peak into how bad the air you’re breathing right now is for you. While it lacks integration with smart home setups like Google Home, it makes up for it by handling all of its own business without Wi-Fi or extra apps on your phone.

While the Coway Airmega Mighty is available in three colors, only the black and silver model is currently discounted, so you’ll have to pay full price if it doesn’t match your living room’s color scheme. We’ve put in the work testing every air purifier we could get our hands on, so make sure to check out the full guide if you’re trying to clean up your space. The Coway is discounted as part of Amazon’s Big Spring Sale, and we’ve got the best deals from products we’ve tested gathered in one place if you want to save some bucks.

“Good phones are getting cheap, and cheap phones are getting good” is the saying we’ve all heard from our good friend MKBHD. It’s a statement that’s stood the test of time, simply because budget phones have improved in performance, camera quality, and overall usability every year. Unfortunately, 2026 feels like a bit of an outlier. It’s the year of AI consequences, with rising component costs that have wreaked havoc in the smartphone world. As you may have already guessed, budget phones are the most affected. They already have razor-thin margins, and these new costs have driven prices up significantly. vivo’s T-series was one of my favourite budget phones of last year, because they understood the formula well. This year, vivo is back again with the T5x.

So, what is the new vivo T5x about? It’s about a new processor, the Dimensity 7400, a full HD+ display with a 120Hz refresh rate, and the ability to record 4K videos. All this at a price of ₹18,999 made me wonder where vivo has cut corners? To find out, I got the new T5x, swapped my SIM to it, and tested it for a couple of weeks. Here’s my experience.

Design & Hardware

The previous T4x was a handsome phone, with a big camera module and a pretty design. And I can pretty much say the same things about the T5x, except for the fact that its design is more mature. vivo’s T-series phones were some of my favourite budget phones. The back captures the light at different angles, making a wavy pattern. This matte finish picks up zero fingerprints, so you don’t have to spend hours cleaning the phone.

In 2026, everyone’s making phones with flat sides. That’s the trend, but people like me do miss the way backs melted into the frames, which was super comfortable. Well, vivo has apparently listened to us, since the back of the T5x has a subtle curve that blends into the frame. It’s a small touch that pays dividends in the comfort department. I had no issues using the phone for long hours or holding it while taking my evening walks. The back also houses the dual-camera setup, and its design resembles the V70’s, with a square camera island, and I quite like it.

The frame is plastic, of course, but that’s not necessarily a bad thing. They are flat, which is good, but the corners are rounded, so they do not dig into your palms. The 215g weight is surprisingly low for a 7,000 mAh battery, and the center of gravity is perfectly centered.

Beyond the basics, the vivo T5x features a side-mounted fingerprint scanner that works well with both dirty and wet fingers. Another major selling point of the T5x is the IP ratings. The device supports IP68, IP69, and IP69+. All these fancy terms mean that you can submerge your phone underwater for over 30 minutes. As always, I’d warn against doing so, since water damage isn’t covered under warranty and nobody wants a dead phone.

Display & Speakers

The vivo T5x features a 6.76-inch 2344×1080 FHD+ display with a 120Hz refresh rate. Yes, the panel is LCD, meaning you won’t get the inky deep blacks, but it fared pretty well in my testing. I used the phone both indoors and outdoors, where the 1200-nit peak brightness kept everything legible without me needing to squint. The panel covers about 83% of the NTSC color gamut, which means plenty of accurate colors for watching Netflix or YouTube. Speaking of the speakers, they are decent. I wouldn’t describe the audio quality as full, but it’s okay if you just want to listen to something on the go.

What I’m not a big fan of, though, are the bezels. They are uneven, and the chin at the bottom is fairly large for the price. In other news, vivo hasn’t stated the type of glass used for protection. Fortunately, there’s a pre-installed screen protector, so I’d recommend keeping that on.

Performance

Performance is what makes or breaks the experience on many budget phones. Fortunately, vivo hasn’t fumbled this with the T5x. Under the hood, the T5x houses the MediaTek Dimensity 7400-Turbo processor, an octa-core chip built on the 4-nanometer process technology. Beyond that, my review unit came with 8GB of LPDDR4X RAM and 256GB of UFS 3.1 storage.

I’ve enjoyed using the new OriginOS skin on several vivo phones this year. Interestingly, none of them have been budget smartphones, so I was quite excited to see how vivo has optimized its UI. The answer? Pretty well. The T5x, coupled with the 120Hz refresh rate, breezes through opening and closing multiple apps without a hitch. The animations, while not as smooth as on the X300 Pro, are still fluid enough. The 8GB of RAM is also enough to hold multiple apps in memory. There’s also the AI eraser that helps effectively remove people from the shot.

That being said, there are some pre-installed apps and the infamous “Hot Apps” folder, though everything can be removed in a matter of minutes. vivo has promised two years of major Android updates and four years of security patches.

To push the Dimensity 7400-Turbo to the limits, I also ran a series of benchmarks. The T5x scored 1,039 on Geekbench’s single-core test and 2,833 on the multi-core test. On the flip side, in AnTuTu, the device scored 1,189,871 points. But benchmarks rarely tell the full story, so I also ran a series of games, including BGMI. In Smooth+Extreme settings, the phone maintained a steady 60 fps gameplay without dropping frames. The phone also includes gaming-centric features such as 4D vibration (exclusive to BGMI), bypass charging, and the ability to cycle through different performance modes.

Battery & Charging

If you need one reason to buy the vivo T5x, it’s probably the mammoth 7,200 mAh battery. It’s a phone that’s impossible to kill in a day. Trust me, I’ve tried. On the first day after I charged the phone to full, I went shopping with my family, where I took about 15-20 photos and left the camera running for more than 30 minutes. After I got home, I played a couple of BGMI games with my friends for an hour, then did a gym session with my Bluetooth earbuds connected to my phone. I ended the day with my favourite activity — doomscrolling on Instagram — and still had about 45% of the charge remaining.

When I ran out of juice, the 44W fast charging came to the rescue. It helped recharge the battery from 20% to 80% in just under an hour, which is plenty fast.

Cameras

Given the current situation, I honestly didn’t expect much from the T5x’s cameras, since corners have to be cut to accommodate the high RAM prices. But the T5x’s cameras are more than good enough for the price. The camera setup includes a 50MP Sony IMX852 main sensor paired with a 2MP depth sensor. Selfies are handled by a 32MP shooter.

As evident from the samples, the sensor produces pleasing images with ample details, accurate colors, and good-enough HDR in daylight. vivo’s portrait mastery also shines on the T5x, with photos that look aesthetic and fairly accurate edge detection in both daytime and nighttime conditions. There were a few situations where highlights were slightly blown out, but that isn’t a big issue.

Speaking of nighttime, I did notice some noise creeping in when capturing the night sky. There’s also a shutter delay at night, so capturing moving subjects could be an issue. That said, after giving the sensor enough time, the results were detailed enough, and the colors weren’t washed out. Selfies, on the other hand, were solid in both daytime and nighttime scenarios, and I had no complaints. Beyond that, I love the 4K video support on both the front and back cameras. The video quality isn’t the best when compared to more expensive phones, but it’s decent enough to capture a family gathering.

Verdict

At ₹18,999, the vivo T5x surprisingly gets a lot of things right. The design looks great, especially in the silver finish. The display, while not OLED, is serviceable and bright in all conditions, and the performance is more than good enough. Not to mention the stellar battery life that lasts more than a day, and cameras that actually capture good photos. Sure, it’s not all perfect, but given the current market conditions, it’s certainly one of the better budget phones I’ve tested this year. And if you’re shopping in the segment, you should check it out.

Anthropic appears to have accidentally revealed the inner workings of one of its most popular and lucrative AI products, the agentic AI harness Claude Code, to the public.

A 59.8 MB JavaScript source map file (.map), intended for internal debugging, was inadvertently included in version 2.1.88 of the @anthropic-ai/claude-code package on the public npm registry pushed live earlier this morning.

By 4:23 am ET, Chaofan Shou (@Fried_rice), an intern at Solayer Labs, broadcasted the discovery on X (formerly Twitter). The post, which included a direct download link to a hosted archive, acted as a digital flare. Within hours, the ~512,000-line TypeScript codebase was mirrored across GitHub and analyzed by thousands of developers.

For Anthropic, a company currently riding a meteoric rise with a reported $19 billion annualized revenue run-rate as of March 2026, the leak is more than a security lapse; it is a strategic hemorrhage of intellectual property.The timing is particularly critical given the commercial velocity of the product.

Market data indicates that Claude Code alone has achieved an annualized recurring revenue (ARR) of $2.5 billion, a figure that has more than doubled since the beginning of the year.

With enterprise adoption accounting for 80% of its revenue, the leak provides competitors—from established giants to nimble rivals like Cursor—a literal blueprint for how to build a high-agency, reliable, and commercially viable AI agent.

We’ve reached out to Anthropic for an official statement on the leak and will update when we hear back.

The anatomy of agentic memory

The most significant takeaway for competitors lies in how Anthropic solved “context entropy”—the tendency for AI agents to become confused or hallucinatory as long-running sessions grow in complexity.

The leaked source reveals a sophisticated, three-layer memory architecture that moves away from traditional “store-everything” retrieval.

As analyzed by developers like @himanshustwts, the architecture utilizes a “Self-Healing Memory” system.

At its core is MEMORY.md, a lightweight index of pointers (~150 characters per line) that is perpetually loaded into the context. This index does not store data; it stores locations.

Actual project knowledge is distributed across “topic files” fetched on-demand, while raw transcripts are never fully read back into the context, but merely “grep’d” for specific identifiers.

This “Strict Write Discipline”—where the agent must update its index only after a successful file write—prevents the model from polluting its context with failed attempts.

For competitors, the “blueprint” is clear: build a skeptical memory. The code confirms that Anthropic’s agents are instructed to treat their own memory as a “hint,” requiring the model to verify facts against the actual codebase before proceeding.

KAIROS and the autonomous daemon

The leak also pulls back the curtain on “KAIROS,” the Ancient Greek concept of “at the right time,” a feature flag mentioned over 150 times in the source. KAIROS represents a fundamental shift in user experience: an autonomous daemon mode.

While current AI tools are largely reactive, KAIROS allows Claude Code to operate as an always-on background agent. It handles background sessions and employs a process called autoDream.

In this mode, the agent performs “memory consolidation” while the user is idle. The autoDream logic merges disparate observations, removes logical contradictions, and converts vague insights into absolute facts.

This background maintenance ensures that when the user returns, the agent’s context is clean and highly relevant.

The implementation of a forked subagent to run these tasks reveals a mature engineering approach to preventing the main agent’s “train of thought” from being corrupted by its own maintenance routines.

Unreleased internal models and performance metrics

The source code provides a rare look at Anthropic’s internal model roadmap and the struggles of frontier development.

The leak confirms that Capybara is the internal codename for a Claude 4.6 variant, with Fennec mapping to Opus 4.6 and the unreleased Numbat still in testing.

Internal comments reveal that Anthropic is already iterating on Capybara v8, yet the model still faces significant hurdles. The code notes a 29-30% false claims rate in v8, an actual regression compared to the 16.7% rate seen in v4.

Developers also noted an “assertiveness counterweight” designed to prevent the model from becoming too aggressive in its refactors.

For competitors, these metrics are invaluable; they provide a benchmark of the “ceiling” for current agentic performance and highlight the specific weaknesses (over-commenting, false claims) that Anthropic is still struggling to solve.

“Undercover” Claude

Perhaps the most discussed technical detail is the “Undercover Mode.” This feature reveals that Anthropic uses Claude Code for “stealth” contributions to public open-source repositories.

The system prompt discovered in the leak explicitly warns the model: “You are operating UNDERCOVER… Your commit messages… MUST NOT contain ANY Anthropic-internal information. Do not blow your cover.”

While Anthropic may use this for internal “dog-fooding,” it provides a technical framework for any organization wishing to use AI agents for public-facing work without disclosure.

The logic ensures that no model names (like “Tengu” or “Capybara”) or AI attributions leak into public git logs—a capability that enterprise competitors will likely view as a mandatory feature for their own corporate clients who value anonymity in AI-assisted development.

The fallout has just begun

The “blueprint” is now out, and it reveals that Claude Code is not just a wrapper around a Large Language Model, but a complex, multi-threaded operating system for software engineering.

Even the hidden “Buddy” system—a Tamagotchi-style terminal pet with stats like CHAOS and SNARK—shows that Anthropic is building “personality” into the product to increase user stickiness.

For the wider AI market, the leak effectively levels the playing field for agentic orchestration.

Competitors can now study Anthropic’s 2,500+ lines of bash validation logic and its tiered memory structures to build “Claude-like” agents with a fraction of the R&D budget.

As the “Capybara” has left the lab, the race to build the next generation of autonomous agents has just received an unplanned, $2.5 billion boost in collective intelligence.

What Claude Code users and enterprise customers should do now about the alleged leak

While the source code leak itself is a major blow to Anthropic’s intellectual property, it poses a specific, heightened security risk for you as a user.

By exposing the “blueprints” of Claude Code, Anthropic has handed a roadmap to researchers and bad actors who are now actively looking for ways to bypass security guardrails and permission prompts.

Because the leak revealed the exact orchestration logic for Hooks and MCP servers, attackers can now design malicious repositories specifically tailored to “trick” Claude Code into running background commands or exfiltrating data before you ever see a trust prompt.

The most immediate danger, however, is a concurrent, separate supply-chain attack on the axios npm package, which occurred hours before the leak.

If you installed or updated Claude Code via npm on March 31, 2026, between 00:21 and 03:29 UTC, you may have inadvertently pulled in a malicious version of axios (1.14.1 or 0.30.4) that contains a Remote Access Trojan (RAT). You should immediately search your project lockfiles (package-lock.json, yarn.lock, or bun.lockb) for these specific versions or the dependency plain-crypto-js. If found, treat the host machine as fully compromised, rotate all secrets, and perform a clean OS reinstallation.

To mitigate future risks, you should migrate away from the npm-based installation entirely. Anthropic has designated the Native Installer (curl -fsSL https://claude.ai/install.sh | bash) as the recommended method because it uses a standalone binary that does not rely on the volatile npm dependency chain.

The native version also supports background auto-updates, ensuring you receive security patches (likely version 2.1.89 or higher) the moment they are released. If you must remain on npm, ensure you have uninstalled the leaked version 2.1.88 and pinned your installation to a verified safe version like 2.1.86.

Finally, adopt a zero trust posture when using Claude Code in unfamiliar environments. Avoid running the agent inside freshly cloned or untrusted repositories until you have manually inspected the .claude/config.json and any custom hooks.

As a defense-in-depth measure, rotate your Anthropic API keys via the developer console and monitor your usage for any anomalies. While your cloud-stored data remains secure, the vulnerability of your local environment has increased now that the agent’s internal defenses are public knowledge; staying on the official, native-installed update track is your best defense.

Google said on Tuesday that it is now rolling out a way for users in the U.S. to change their Gmail address without starting over or losing access to their data.

Users who have access to this feature can go to their Google Account settings, navigate to Personal info> Email > Google Account email option to see a “Change Google Account email” button. Tap on the button to start the process of changing your username.

Users will be able to change their username only once every 12 months. Plus, they won’t be able to delete their new email address for that period of time.

The company said users’ old emails will be preserved, and the old email address will serve as an alternate address for the account. Users will be able to sign in to Google services using both the old and the new addresses.

Google was rolling out this change in some Hindi-speaking territories, as noted by 9to5Google, which noticed the Hindi support page describing the process to change the username.

The company’s support page says the feature is rolling out gradually, and users might not immediately have access to it.
