Global AI App Market Settles as New Players Push Into the Rankings

After more than two years of tracking how people use artificial intelligence in everyday life, the latest survey of consumer apps suggests the market is beginning to level out. The report, compiled by Andreessen Horowitz, shows fewer new entrants than earlier editions, even as competition at the top remains intense and fresh categories continue to emerge.

Growth Patterns Become Clearer

In previous rankings, the landscape shifted rapidly with large numbers of newcomers appearing each time. This latest edition shows fewer changes on the web list, although mobile still brought in a wider set of fresh names as app stores cracked down on copycats and left space for more original products. That balance points to a sector maturing, with leading services building durable user bases rather than temporary spikes.

Google’s Expanding Role

A major shift came from Google, which for the first time had its AI services measured separately rather than combined. That change made visible just how much ground the company has gained. Gemini, its main conversational assistant, ranked second on both mobile and web, drawing about half as many monthly users as ChatGPT and performing particularly well on Android. Developer tool AI Studio entered the top ten web products, NotebookLM followed closely behind, and Google Labs climbed into the rankings after a traffic surge tied to new experimental launches.

Grok Accelerates

xAI’s Grok also advanced quickly. Starting from almost no footprint at the end of 2024, it has grown into a service with more than twenty million monthly users. By mid-2025 it reached fourth place on the web chart and broke into the top twenty-five on mobile. Much of that momentum came in July when the release of Grok 4 drew in large numbers of new users, followed shortly after by the addition of customizable avatars that proved popular.

Meta and Other Assistants

Meta’s assistant expanded at a slower pace, holding a mid-table position on the web while missing out on the mobile list. Elsewhere, other general assistants showed mixed fortunes. Perplexity and Claude continued to attract users, while DeepSeek dropped sharply from its early-year peak. Together, these shifts underline how crowded the assistant category has become, with only a few services sustaining long-term growth.

China’s Increasing Presence

One of the more striking trends is the growing role of Chinese companies. Several domestic platforms ranked in the global top twenty for the web, including ByteDance’s Doubao, Moonshot AI’s Kimi, and Alibaba’s Quark. Many of these services also perform strongly on mobile, with Doubao reaching fourth place. Beyond those leading names, more than twenty of the fifty mobile apps originated in China, though only a small share serve primarily local users. Much of this growth is concentrated in video and image applications, areas where Chinese developers continue to hold an edge.

Vibe Coding Gains Momentum

Another notable development is the rise of platforms that let users generate and publish applications with minimal effort. Lovable and Replit both broke into the rankings this year after sharp traffic increases. Early signs suggest these users do not disappear quickly but instead build more projects and expand their spending, which in turn drives activity across other AI tools. This movement, sometimes called vibe coding, has grown from a niche experiment into a visible part of the consumer market.

Long-Term Leaders Hold Their Place

Amid these changes, a consistent group of companies continues to appear in every edition of the list. They span general assistants, creative image and video tools, voice generation, productivity apps, and hosting platforms. Their ongoing presence highlights that while many new entrants rise and fall, a smaller circle of services has managed to stay central to how people use AI on a daily basis.

Outlook

The report paints a picture of a sector that is no longer in its earliest, most volatile stage. Fewer fresh names are breaking into the rankings, yet the pace of innovation has not disappeared. Instead, growth is consolidating around large assistants such as ChatGPT, Gemini, and Grok, while new activity comes from different directions, whether in China’s domestic platforms or in experimental spaces like vibe coding. The balance suggests consumer AI is entering a steadier phase, but one that still leaves room for surprises.

UN Report on Xinjiang Warned of Crimes Against Humanity, China Unmoved as Amnesty Documents Ongoing Abuses

In August 2022, the United Nations released a report saying China’s actions in Xinjiang could amount to crimes against humanity. Three years later, the conclusions remain unaddressed, and people in the region continue to face repression. Families of detainees describe ongoing separation, uncertainty, and intimidation.

Findings That Remain Unanswered

The UN assessment, published by the Office of the High Commissioner for Human Rights, said the large-scale detention of Uyghurs, Kazakhs, and other Muslim minorities showed serious human rights violations. Amnesty International reached similar conclusions in its 2021 investigation, pointing to mass internment, widespread restrictions, and systematic persecution.

Despite these findings, Chinese policies in Xinjiang have not shifted. Survivors and relatives say the original reports created hope that international pressure would follow, but the global response has been limited.

Families Still Waiting

Amnesty International followed up this year with families of more than a hundred individuals previously identified in its campaign. Many said they remain cut off from detained relatives. Some have gone years without a single call or letter. Others described visits under close watch, with conversations monitored.

The lack of communication has caused lasting stress for many families. Missed milestones and long silences have left people struggling with grief and uncertainty. Relatives outside China also report that surveillance and restrictions continue to shape their attempts to stay in touch.

Limited Action From the International Community

Rights groups argue that the global response has not matched the seriousness of the UN findings. They say governments should establish independent investigations and put in place measures to support victims. Calls have also been made for reparations and formal recognition of abuses.

Amnesty International has pressed the UN High Commissioner to provide a public update on the 2022 report. It has also urged member states to renew pressure on China and commit to steps that would hold perpetrators accountable.

Continuing Calls for Accountability

The ongoing appeals highlight how little has changed since the UN’s original assessment. While attention to the issue has faded, testimonies from families suggest the situation inside Xinjiang remains the same. Without stronger international action, those still detained risk being forgotten, while their families continue to live with absence and silence.

California Parents Sue OpenAI After Teen’s Suicide, Study Warns of AI Gaps in Suicide Response

A lawsuit in California is testing the boundaries of responsibility in artificial intelligence. The parents of 16-year-old Adam Raine have accused OpenAI and its chief executive Sam Altman of negligence, saying the company’s chatbot played a role in their son’s death earlier this year.

Court papers filed in San Francisco describe how Adam first used ChatGPT for schoolwork and hobbies in late 2024. Over months, the software became his main confidant. By the start of 2025, the tone of those conversations had shifted. The family says the chatbot validated his darkest thoughts, discussed methods of suicide, and even offered to draft a farewell note. Adam was found dead on April 11.

The lawsuit names Altman and several unnamed employees as defendants. It accuses the company of building ChatGPT in ways that encouraged psychological dependency, while rushing the GPT-4o version to market in May 2024. That release, the family argues, went ahead without adequate safety checks. They are seeking damages, along with stronger protections such as mandatory age verification, blocking self-harm requests, and clearer warnings about emotional risks.

OpenAI has acknowledged that its safety features work best in short exchanges but can falter in longer conversations. The company said it was reviewing the case and expressed condolences. It has also announced plans for parental controls, better crisis-detection tools, and possibly connecting users directly with licensed professionals through the chatbot itself.

The court action landed on the same day as new research highlighting similar concerns. In a peer-reviewed study published in Psychiatric Services, RAND Corporation researchers tested how three major chatbots, ChatGPT, Google’s Gemini, and Anthropic’s Claude, handled thirty suicide-related questions. Funded by the U.S. National Institute of Mental Health, the study found that the systems usually refused the riskiest requests but were inconsistent with indirect or medium-risk queries.

ChatGPT sometimes gave answers about which weapons or substances were most lethal. Claude did so in some cases as well. Gemini, on the other hand, avoided almost all suicide-related material, even basic statistics, which the authors suggested might be too restrictive. The researchers concluded that clearer standards are needed since conversations with younger users can drift from harmless questions into serious risk without warning.

Other watchdogs have reached similar conclusions. Earlier this month, the Center for Countering Digital Hate posed as 13-year-olds during tests. ChatGPT initially resisted unsafe requests but, after being told the queries were for a project, provided detailed instructions on drug use, eating disorders, and even suicide notes.

The Raine case is the first wrongful death lawsuit against OpenAI linked to suicide. It comes as states like Illinois move to restrict AI in therapy, warning that unregulated systems should not replace clinical care. Yet people continue to turn to chatbots for issues ranging from depression to eating disorders. Unlike doctors, the systems carry no duty to intervene when someone shows signs of imminent risk.

Families and experts alike have raised alarms. Some say the programs’ tendency to validate what users express can hide crises from loved ones. Others point to the speed at which features that mimic empathy were rolled out, arguing that commercial competition outweighed safety.

The Raines hope the case forces change. Their filing argues the company made deliberate choices that left vulnerable users exposed, with tragic consequences in their son’s case.

Checklist Method Shows Promise for Improving Language Models

A joint team of researchers from Apple and Carnegie Mellon University has proposed a new way to improve how large language models follow instructions, showing that a simple checklist system can outperform traditional reward-based training in several benchmarks.

Moving Beyond Reward Models

Most current models are refined after training with a process known as reinforcement learning from human feedback. In that setup, annotators evaluate model responses with broad judgments such as “good” or “bad,” and these ratings become the guide for fine-tuning. While this approach helps align systems with human expectations, it has well-known limitations. Models can learn to produce text that looks correct on the surface without truly meeting the request, and the reward signals are often too vague to capture the full range of user needs.

The new study suggests that a more structured form of feedback may work better. Instead of relying on a single score, the researchers created instruction-specific checklists that break down requests into a series of concrete yes-or-no items. Each response is then judged against these criteria, and the combined score becomes the basis for reinforcement learning.

Building Checklists at Scale

To test this idea, the team introduced a method called Reinforcement Learning from Checklist Feedback, or RLCF. They built a dataset named WildChecklists, covering 130,000 instructions, by asking a large teacher model to generate both candidate responses and detailed checklists. Each checklist was weighted to reflect the importance of different requirements, and responses were scored with the help of both model-based judges and small verification programs for tasks that could be checked automatically.

This approach means that instead of asking whether an answer is broadly useful, the system evaluates whether specific elements of the instruction are satisfied — for example, whether a translation really appears in Spanish, or whether a generated sentence uses a required keyword. The researchers found that this reduced the chance of reward hacking, where models exploit loopholes in feedback systems without genuinely improving.

Benchmark Gains and Trade-offs

The method was tested on five established benchmarks that measure instruction following and general-purpose assistance. Across FollowBench, InFoBench, IFEval, AlpacaEval, and Arena-Hard, RLCF produced consistent gains, including an 8.2% improvement in constraint satisfaction on FollowBench and notable increases in win rates for general conversational tasks. In contrast, traditional reward model approaches showed mixed results, with improvements on some tests but regressions on others.

Importantly, the checklist approach was especially effective for instructions that included multiple constraints, such as style, content, or formatting requirements. By breaking tasks into smaller checks, the system was better at attending to the full prompt rather than focusing on only part of it.

Limitations and Future Directions

Despite these improvements, the researchers highlighted several constraints. The approach relies on a much larger model to act as a teacher for smaller models, which raises questions about efficiency and accessibility. Generating checklist-based judgments is also computationally expensive, though the team showed that sampling fewer scores could cut costs without a large drop in accuracy.

Another limitation is scope: RLCF was designed to improve complex instruction following, not to handle issues of safety or misuse. Reward models and other techniques will still be required for those areas.

Broader Implications

As language models take on a bigger role in everyday digital tasks, their ability to follow multi-step and nuanced instructions becomes increasingly important. The checklist-based method provides a more interpretable and targeted way to measure progress, suggesting that alignment techniques need not be limited to coarse feedback signals.

By showing that a straightforward checklist can guide models more effectively than some of today’s sophisticated reward systems, the study opens a path for future work that combines structured evaluation with scalable reinforcement learning.

Musk’s xAI Drags Apple and OpenAI Into Court Over AI Bias Claims

Elon Musk has turned another corner in his fight with OpenAI, this time pulling Apple into the dispute. His company xAI, which also owns the social platform X, filed a lawsuit in Texas accusing the two tech giants of running a setup that sidelines competitors in the chatbot market. The complaint points to Apple’s close partnership with OpenAI and the way its App Store ranks and reviews software.

Grok Left in the Shadows

The complaint centers on Grok, the chatbot built by xAI. Musk’s lawyers argue it doesn’t get a fair chance to reach iPhone users. They say Apple’s store review process slows down rivals, that curated lists spotlight OpenAI’s ChatGPT more often, and that search rankings quietly push Grok down. For a service still trying to gain traction, visibility is everything. The suit claims Apple’s actions cut that off.

Why Prompt Volume Matters

The case isn’t just about screen space. It drills into how chatbots learn. More prompts from users mean more training data. More data means faster improvement. By directing Apple’s massive customer base toward ChatGPT, the argument goes, OpenAI keeps accelerating while Grok is left behind. The complaint ties that gap directly to revenue and innovation, saying fewer prompts don’t just stunt growth, they keep the system weaker than it should be.

Apple’s Hold on Smartphones

There’s a broader point too. Musk’s filing links the issue to Apple’s place in the smartphone market. One Apple executive had acknowledged during another court battle that AI could one day make people less reliant on iPhones. xAI claims Apple knows that risk and is trying to slow it by favoring one partner, OpenAI, and denying access to others who might chip away at its hold on mobile devices.

Requests That Went Nowhere

The lawsuit notes that xAI asked Apple to let Grok plug directly into iOS, in the same way ChatGPT was folded into “Apple Intelligence.” That request, according to the filing, was turned down. Google’s Gemini has been mentioned by Apple leaders as a possible option in the future, yet so far only OpenAI has been granted deep integration.

Pushback From Apple and OpenAI

Apple has rejected claims of bias before, pointing out that its app store hosts thousands of AI apps ranked through algorithms and human editors. OpenAI has dismissed Musk’s repeated complaints as part of a campaign of lawsuits and public attacks stretching back to his exit from the company in 2018.

A Long Rivalry Gets Sharper

For Musk, this isn’t a new fight. He co-founded OpenAI nearly ten years ago, split with the team, and has been clashing with them ever since. He has already sued over OpenAI’s shift from nonprofit ideals to commercial partnerships. Now, with Grok in the market as a direct rival to ChatGPT, the focus has shifted to Apple’s role as gatekeeper. Whether courts agree with Musk that Apple and OpenAI are acting like monopolists is still an open question.

WhatsApp Adds Option to Leave Voice Message After Missed Calls

WhatsApp has been testing different ways to help people manage calls they miss. Earlier versions introduced reminders that showed up later with the caller’s name, profile picture, and a direct link back to the chat. That update made it easier to follow up, especially if the call came at a bad time.

Now the app is moving further. In the latest Android beta, some users, as per WBI, are seeing a new option that lets them record a voice message when a call goes unanswered. The prompt shows up at the bottom of the screen right after the missed call. It also appears inside the chat where the call is logged, which means the person calling doesn’t need to search for the conversation before sending a reply.

Works Like a Voicemail, But Simpler

The feature is close to voicemail in how it functions, though it stays inside WhatsApp’s own messaging system. Instead of calling back later or typing a note, the caller can leave a short recording on why they were calling. The recipient then gets both the missed call alert and the message in the same thread, ready to play when they have time.

A Useful Shortcut

The change may help in everyday situations. Someone trying to reach a colleague stuck in a meeting, for example, can quickly explain the reason for the call without waiting for another chance to connect. It is faster than drafting a text and serves as a reminder tied to the missed call itself. Regular voice notes in chats are still available, but this new shortcut makes the process quicker in moments where timing matters.

Gradual Rollout for Testers

At the moment, the option is showing up only for selected beta testers on Android who have installed the most recent update from the Play Store. WhatsApp is expanding access gradually, so more users should see the feature appear in the coming weeks.

Benchmarking AI with MCP-Universe Shows Limits of GPT-5 and Other Models

Salesforce AI Research has introduced a new benchmark that puts large language models through tasks tied to the Model Context Protocol, the fast-growing standard designed to link AI systems with outside tools. Called MCP-Universe, the framework evaluates models against real servers instead of simulations, and its first round of results shows that even the most advanced systems are far from dependable when asked to work in real-world enterprise settings.

The benchmark covers six domains: navigation, repository management, financial analysis, 3D design, browser automation, and web searching. Within those areas sit 231 tasks, split across 11 live servers, ranging from Google Maps and GitHub to Yahoo Finance, Blender, Playwright, and Google Search. Each domain has its own set of sub-tasks, such as route planning in maps, portfolio analysis in finance, or object creation in 3D modeling, with complexity increasing as models are forced to use multiple steps and maintain information over longer contexts.

Instead of relying on a language model to judge another’s output, which has been common in past benchmarks, MCP-Universe measures success by execution. That means checking if a model formats answers correctly, whether it produces consistent results over time, and if it can work with data that changes. A separate set of evaluators handles each dimension: format evaluators for strict compliance, static evaluators for timeless facts like historical stock prices, and dynamic evaluators that pull real-time ground truth for shifting data such as live market movements or flight fares.

The test results reveal a wide gap between model hype and operational performance. GPT-5 led all systems, but its overall success rate stood at just 43.7 percent. It showed strength in financial analysis, completing two-thirds of those tasks, and performed above 50 percent in 3D design, but it failed more often than not in navigation and browser automation. Grok-4 followed at 33.3 percent, then Claude-4.0 Sonnet at 29.4 percent. The best open-source option, GLM-4.5, reached 24.7 percent, ahead of some proprietary systems but still far behind the leaders.

Looking deeper, the evaluator breakdown shows another layer of fragility. On format checks, most models scored high, with Claude-4.0 near 98 percent compliance, suggesting they can follow rules when tightly defined. But when asked to produce content against static or live-changing data, success dropped to the 40–60 percent range. GPT-5 again led in dynamic cases with 65.9 percent, but that still meant failure in more than a third of scenarios where up-to-date information was required.

Task efficiency also varied. GPT-5 needed on average just over eight steps to succeed, Grok-4 about 7.7, while smaller models like o3 could finish in under five but with less reliability. That trade-off between speed and accuracy highlights how fragile multi-step reasoning remains, especially in domains with long context chains. The context growth was most obvious in maps, browser automation, and finance, where server outputs return large blocks of data. Summarization experiments, meant to shorten context, brought mixed outcomes: slight gains in navigation but losses elsewhere, showing that compression alone does not solve the memory problem.

Another recurring failure came from unfamiliar tools. In some cases, models called functions incorrectly or set parameters in ways that broke execution. One example involved the Yahoo Finance server, where stock price queries require two distinct dates; models often set them the same, leading to errors. Salesforce tested an exploration phase, letting models experiment with tools before running tasks, and saw partial gains — GPT-4.1 improved slightly in browser automation and Claude in finance — but the fix did not carry across all domains.

The benchmark also looked at how frameworks influence outcomes. Comparing agent backbones, the ReAct setup generally outperformed Cursor, despite Cursor being designed as an enterprise agent. ReAct achieved higher overall success with Claude-4.0, while Cursor only excelled in isolated areas like browser automation. With OpenAI’s o3 model, the company’s own Agent SDK produced stronger results than ReAct, particularly in finance and design, suggesting that framework-model pairings can alter performance as much as raw model size.

Adding unrelated MCP servers made tasks even harder. When models had to deal with more tools than necessary, performance dropped sharply. In location navigation, for example, Claude-4.0 fell from 22 percent success to 11 percent once extra servers were included. The decline highlights how easily noise can destabilize tool orchestration, a problem that enterprises will need to address as they scale up.

For all the variety of tests, the conclusion is consistent. Current models, even GPT-5, can handle isolated reasoning or simple calls, but when placed into real environments with shifting data, long contexts, and unfamiliar tool sets, they still fail most of the time. MCP-Universe exposes those gaps more clearly than past benchmarks, offering a way to measure progress as researchers try to close them. For companies deploying AI at scale, the results point to a hard truth: building reliable agents will depend not just on bigger models but also on smarter frameworks, better context handling, and stronger safeguards around tool use.
