This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

Inside India’s scramble for AI independence

Despite its status as a global tech hub, India lags far behind the likes of the US and China when it comes to homegrown AI.

That gap has opened largely because India has chronically underinvested in R&D, institutions, and invention. Meanwhile, since no one native language is spoken by the majority of the population, training language models is far more complicated than it is elsewhere.

So when the open-source foundation model DeepSeek-R1 suddenly outperformed many global peers, it struck a nerve. This launch by a Chinese startup prompted Indian policymakers to confront just how far behind the country was in AI infrastructure—and how urgently it needed to respond. Read the full story.

Deepfakes of your dead loved ones are a booming Chinese business

Once a week, Sun Kai has a video call with his mother, and they discuss his day-to-day life. But Sun’s mother died five years ago, and the person he’s talking to isn’t actually a person, but a digital replica he made of her.

There are plenty of people like Sun who want to use AI to preserve, animate, and interact with lost loved ones as they mourn and try to heal. The market is particularly strong in China, where at least half a dozen companies are now offering such technologies and thousands of people have already paid for them.

But some question whether interacting with AI replicas of the dead is truly a healthy way to process grief, and it’s not entirely clear what the legal and ethical implications of this technology may be. Read the full story.

In Bengaluru, India, Adithya Kolavi felt a mix of excitement and validation as he watched DeepSeek unleash its disruptive language model on the world earlier this year. The Chinese technology rivaled the best of the West in terms of benchmarks, but it had been built with far less capital in far less time. 

“I thought: ‘This is how we disrupt with less,’” says Kolavi, the 20-year-old founder of the Indian AI startup CognitiveLab. “If DeepSeek could do it, why not us?” 

But for Abhishek Upperwal, founder of Soket AI Labs and architect of one of India’s earliest efforts to develop a foundation model, the moment felt more bittersweet. 

Upperwal’s model, called Pragna-1B, had struggled to stay afloat with tiny grants while he watched global peers raise millions. The multilingual model had a relatively modest 1.25 billion parameters and was designed to reduce the “language tax,” the extra costs that arise because India—unlike the US or even China—has a multitude of languages to support. His team had trained it, but limited resources meant it couldn’t scale. As a result, he says, the project became a proof of concept rather than a product. 

“If we had been funded two years ago, there’s a good chance we’d be the ones building what DeepSeek just released,” he says.

Kolavi’s enthusiasm and Upperwal’s dismay reflect the spectrum of emotions among India’s AI builders. Despite its status as a global tech hub, the country lags far behind the likes of the US and China when it comes to homegrown AI. That gap has opened largely because India has chronically underinvested in R&D, institutions, and invention. Meanwhile, since no one native language is spoken by the majority of the population, training language models is far more complicated than it is elsewhere. 

Historically known as the global back office for the software industry, India has a tech ecosystem that evolved with a services-first mindset. Giants like Infosys and TCS built their success on efficient software delivery, but invention was neither prioritized nor rewarded. Meanwhile, India’s R&D spending hovered at just 0.65% of GDP ($25.4 billion) in 2024, far behind China’s 2.68% ($476.2 billion) and the US’s 3.5% ($962.3 billion). The muscle to invent and commercialize deep tech, from algorithms to chips, was just never built.

Isolated pockets of world-class research do exist within government agencies like the DRDO (Defense Research & Development Organization) and ISRO (Indian Space Research Organization), but their breakthroughs rarely spill into civilian or commercial use. India lacks the bridges to connect risk-taking research to commercial pathways, the way DARPA does in the US. Meanwhile, much of India’s top talent migrates abroad, drawn to ecosystems that better understand and, crucially, fund deep tech.

So when the open-source foundation model DeepSeek-R1 suddenly outperformed many global peers, it struck a nerve. This launch by a Chinese startup prompted Indian policymakers to confront just how far behind the country was in AI infrastructure, and how urgently it needed to respond.

India responds

In January 2025, 10 days after DeepSeek-R1’s launch, the Ministry of Electronics and Information Technology (MeitY) solicited proposals for India’s own foundation models, which are large AI models that can be adapted to a wide range of tasks. Its public tender invited private-sector cloud and data‑center companies to reserve GPU compute capacity for government‑led AI research. 

Providers including Jio, Yotta, E2E Networks, Tata, AWS partners, and CDAC responded. Through this arrangement, MeitY suddenly had access to nearly 19,000 GPUs at subsidized rates, repurposed from private infrastructure and allocated specifically to foundational AI projects. This triggered a surge of proposals from companies wanting to build their own models. 

Within two weeks, it had 67 proposals in hand. That number tripled by mid-March. 

In April, the government announced plans to develop six large-scale models by the end of 2025, plus 18 additional AI applications targeting sectors like agriculture, education, and climate action. Most notably, it tapped Sarvam AI to build a 70-billion-parameter model optimized for Indian languages and needs. 

For a nation long restricted by limited research infrastructure, things moved at record speed, marking a rare convergence of ambition, talent, and political will.

“India could do a Mangalyaan in AI,” said Gautam Shroff of IIIT-Delhi, referencing the country’s cost-effective, and successful, Mars orbiter mission. 

Jaspreet Bindra, cofounder of AI&Beyond, an organization focused on teaching AI literacy, captured the urgency: “DeepSeek is probably the best thing that happened to India. It gave us a kick in the backside to stop talking and start doing something.”

The language problem

One of the most fundamental challenges in building foundational AI models for India is the country’s sheer linguistic diversity. With 22 official languages, hundreds of dialects, and millions of people who are multilingual, India poses a problem that few existing LLMs are equipped to handle.

Whereas a massive amount of high-quality web data is available in English, Indian languages collectively make up less than 1% of online content. The lack of digitized, labeled, and cleaned data in languages like Bhojpuri and Kannada makes it difficult to train LLMs that understand how Indians actually speak or search.

Global tokenizers, which break text into units a model can process, also perform poorly on many Indian scripts, misinterpreting characters or skipping some altogether. As a result, even when Indian languages are included in multilingual models, they’re often poorly understood and inaccurately generated.

And unlike OpenAI and DeepSeek, which achieved scale using structured English-language data, Indian teams often begin with fragmented and low-quality data sets encompassing dozens of Indian languages. This makes the early steps of training foundation models far more complex.

Nonetheless, a small but determined group of Indian builders is starting to shape the country’s AI future.

For example, Sarvam AI has created OpenHathi-Hi-v0.1, an open-source Hindi language model that shows the Indian AI field’s growing ability to address the country’s vast linguistic diversity. The model, built on Meta’s Llama 2 architecture, was trained on 40 billion tokens of Hindi and related Indian-language content, making it one of the largest open-source Hindi models available to date.

Pragna-1B, the multilingual model from Upperwal, is more evidence that India could solve for its own linguistic complexity. Trained on 300 billion tokens for just $250,000, it introduced a technique called “balanced tokenization” to address a unique challenge in Indian AI, enabling a 1.25-billion-parameter model to behave like a much larger one.

The issue is that Indian languages use complex scripts and agglutinative grammar, where words are formed by stringing together many smaller units of meaning using prefixes and suffixes. Unlike English, which separates words with spaces and follows relatively simple structures, Indian languages like Hindi, Tamil, and Kannada often lack clear word boundaries and pack a lot of information into single words. Standard tokenizers struggle with such inputs. They end up breaking Indian words into too many tokens, which bloats the input and makes it harder for models to understand the meaning efficiently or respond accurately.

With the new technique, however, “a billion-parameter model was equivalent to a 7 billion one like Llama 2,” Upperwal says. This performance was particularly marked in Hindi and Gujarati, where global models often underperform because of limited multilingual training data. It was a reminder that with smart engineering, small teams could still push boundaries.

Upperwal eventually repurposed his core tech to build speech APIs for 22 Indian languages, a more immediate solution better suited to rural users who are often left out of English-first AI experiences.

“If the path to AGI is a hundred-step process, training a language model is just step one,” he says. 

At the other end of the spectrum are startups with more audacious aims. Krutrim-2, for instance, is a 12-billion-parameter multilingual language model optimized for English and 22 Indian languages. 

Krutrim-2 is attempting to solve India’s specific problems of linguistic diversity, low-quality data, and cost constraints. The team built a custom Indic tokenizer, optimized training infrastructure, and designed models for multimodal and voice-first use cases from the start, crucial in a country where text interfaces can be a problem.

Krutrim’s bet is that its approach will not only enable Indian AI sovereignty but also offer a model for AI that works across the Global South.

Besides public funding and compute infrastructure, India also needs the institutional support of talent, the research depth, and the long-horizon capital that produce globally competitive science.

While venture capital still hesitates to bet on research, new experiments are emerging. Paras Chopra, an entrepreneur who previously built and sold the software-as-a-service company Wingify, is now personally funding Lossfunk, a Bell Labs–style AI residency program designed to attract independent researchers with a taste for open-source science. 

“We don’t have role models in academia or industry,” says Chopra. “So we’re creating a space where top researchers can learn from each other and have startup-style equity upside.”

Government-backed bet on sovereign AI

The clearest marker of India’s AI ambitions came when the government selected Sarvam AI to develop a model focused on Indian languages and voice fluency.

The idea is that it would not only help Indian companies compete in the global AI arms race but benefit the wider population as well. “If it becomes part of the India stack, you can educate hundreds of millions through conversational interfaces,” says Bindra. 

Sarvam was given access to 4,096 Nvidia H100 GPUs for training a 70-billion-parameter Indian language model over six months. (The company previously released a 2-billion-parameter model trained in 10 Indian languages, called Sarvam-1.)

Sarvam’s project and others are part of a larger strategy called the IndiaAI Mission, a $1.25 billion national initiative launched in March 2024 to build out India’s core AI infrastructure and make advanced tools more widely accessible. Led by MeitY, the mission is focused on supporting AI startups, particularly those developing foundation models in Indian languages and applying AI to key sectors such as health care, education, and agriculture.

Under its compute program, the government is deploying more than 18,000 GPUs, including nearly 13,000 high-end H100 chips, to a select group of Indian startups that currently includes Sarvam, Upperwal’s Soket Labs, Gnani AI, and Gan AI. 

The mission also includes plans to launch a national multilingual data set repository, establish AI labs in smaller cities, and fund deep-tech R&D. The broader goal is to equip Indian developers with the infrastructure needed to build globally competitive AI and ensure that the results are grounded in the linguistic and cultural realities of India and the Global South.

According to Abhishek Singh, CEO of IndiaAI and an officer with MeitY, India’s broader push into deep tech is expected to raise around $12 billion in research and development investment over the next five years. 

This includes approximately $162 million through the IndiaAI Mission, with about $32 million earmarked for direct startup funding. The National Quantum Mission is contributing another $730 million to support India’s ambitions in quantum research. In addition to this, the national budget document for 2025-26 announced a $1.2 billion Deep Tech Fund of Funds aimed at catalyzing early-stage innovation in the private sector.

The rest, nearly $9.9 billion, is expected to come from private and international sources including corporate R&D, venture capital firms, high-net-worth individuals, philanthropists, and global technology leaders such as Microsoft. 

IndiaAI has now received more than 500 applications from startups proposing use cases in sectors like health, governance, and agriculture. 

“We’ve already announced support for Sarvam, and 10 to 12 more startups will be funded solely for foundational models,” says Singh. Selection criteria include access to training data, talent depth, sector fit, and scalability.

Open or closed?

The IndiaAI program, however, is not without controversy. Sarvam is being built as a closed model, not open-source, despite its public tech roots. That has sparked debate about the proper balance between private enterprise and the public good. 

“True sovereignty should be rooted in openness and transparency,” says Amlan Mohanty, an AI policy specialist. He points to DeepSeek-R1, which despite its 236-billion parameter size was made freely available for commercial use. 

Its release allowed developers around the world to fine-tune it on low-cost GPUs, creating faster variants and extending its capabilities to non-English applications.

“Releasing an open-weight model with efficient inference can democratize AI,” says Hancheng Cao, an assistant professor of information systems and operations management at Emory University. “It makes it usable by developers who don’t have massive infrastructure.”

IndiaAI, however, has taken a neutral stance on whether publicly funded models should be open-source. 

“We didn’t want to dictate business models,” says Singh. “India has always supported open standards and open source, but it’s up to the teams. The goal is strong Indian models, whatever the route.”

There are other challenges as well. In late May, Sarvam AI unveiled Sarvam‑M, a 24-billion-parameter multilingual LLM fine-tuned for 10 Indian languages and built on top of Mistral Small, an efficient model developed by the French company Mistral AI. Sarvam’s cofounder Vivek Raghavan called the model “an important stepping stone on our journey to build sovereign AI for India.” But its download numbers were underwhelming, with only 300 in the first two days. The venture capitalist Deedy Das called the launch “embarrassing.”

And the issues go beyond the lukewarm early reception. Many developers in India still lack easy access to GPUs and the broader ecosystem for Indian-language AI applications is still nascent. 

The compute question

Compute scarcity is emerging as one of the most significant bottlenecks in generative AI, not just in India but across the globe. For countries still heavily reliant on imported GPUs and lacking domestic fabrication capacity, the cost of building and running large models is often prohibitive. 

India still imports most of its chips rather than producing them domestically, and training large models remains expensive. That’s why startups and researchers alike are focusing on software-level efficiencies that involve smaller models, better inference, and fine-tuning frameworks that optimize for performance on fewer GPUs.

“The absence of infrastructure doesn’t mean the absence of innovation,” says Cao. “Supporting optimization science is a smart way to work within constraints.” 

Yet Singh of IndiaAI argues that the tide is turning on the infrastructure challenge thanks to the new government programs and private-public partnerships. “I believe that within the next three months, we will no longer face the kind of compute bottlenecks we saw last year,” he says.

India also has a cost advantage.

According to Gupta, building a hyperscale data center in India costs about $5 million, roughly half what it would cost in markets like the US, Europe, or Singapore. That’s thanks to affordable land, lower construction and labor costs, and a large pool of skilled engineers. 

For now, India’s AI ambitions seem less about leapfrogging OpenAI or DeepSeek and more about strategic self-determination. Whether its approach takes the form of smaller sovereign models, open ecosystems, or public-private hybrids, the country is betting that it can chart its own course. 

While some experts argue that the government’s action, or reaction (to DeepSeek), is performative and aligned with its nationalistic agenda, many startup founders are energized. They see the growing collaboration between the state and the private sector as a real opportunity to overcome India’s long-standing structural challenges in tech innovation.

At a Meta summit held in Bengaluru last year, Nandan Nilekani, the chairman of Infosys, urged India to resist chasing a me-too AI dream. 

“Let the big boys in the Valley do it,” he said of building LLMs. “We will use it to create synthetic data, build small language models quickly, and train them using appropriate data.” 

His view that India should prioritize strength over spectacle had a divided reception. But it reflects a broader growing consensus on whether India should play a different game altogether.

“Trying to dominate every layer of the stack isn’t realistic, even for China,” says Shobhankita Reddy, a researcher at the Takshashila Institution, an Indian public policy nonprofit. “Dominate one layer, like applications, services, or talent, so you remain indispensable.”

Don’t let hype about AI agents get ahead of reality

—Yoav Shoham is a professor emeritus at Stanford University and cofounder of AI21 Labs.

At Google’s I/O 2025 event in May, the company showed off a digital assistant that didn’t just answer questions; it helped work on a bicycle repair by finding a matching user manual, locating a YouTube tutorial, and even calling a local store to ask about a part, all with minimal human nudging. Such capabilities could soon extend far outside the Google ecosystem.

The vision is exciting: Intelligent software agents that act like digital coworkers, booking your flights, rescheduling meetings, filing expenses, and talking to each other behind the scenes to get things done.

But if we’re not careful, we’re going to derail the whole idea before it has a chance to deliver real benefits. As with many tech trends, there’s a risk of hype racing ahead of reality. And when expectations get out of hand, a backlash isn’t far behind. Read the full story.

Google’s electricity demand is skyrocketing

We got two big pieces of energy news from Google this week. The company announced that it’s signed an agreement to purchase electricity from a fusion company’s forthcoming first power plant. Google also released its latest environmental report, which shows that its energy use from data centers has doubled since 2020.

Taken together, these two bits of news offer a fascinating look at just how desperately big tech companies are hunting for clean electricity to power their data centers as energy demand and emissions balloon in the age of AI. Of course, we don’t know exactly how much of this pollution is attributable to AI because Google doesn’t break that out. (Also a problem!) So, what’s next and what does this all mean?

Who gets to decide who receives experimental medical treatments?

There has been a trend toward lowering the bar for new medicines, and it is becoming easier for people to access treatments that might not help them—and could even harm them. Anecdotes appear to be overpowering evidence in decisions on drug approval. As a result, we’re ending up with some drugs that don’t work.

We urgently need to question how these decisions are made. Who should have access to experimental therapies? And who should get to decide? Such questions are especially pressing considering how quickly biotechnology is advancing. We’re not just improving on existing classes of treatments—we’re creating entirely new ones.

We got two big pieces of energy news from Google this week. The company announced that it’s signed an agreement to purchase electricity from a fusion company’s forthcoming first power plant. Google also released its latest environmental report, which shows that its energy use from data centers has doubled since 2020.

Taken together, these two bits of news offer a fascinating look at just how desperately big tech companies are hunting for clean electricity to power their data centers as energy demand and emissions balloon in the age of AI. Of course, we don’t know exactly how much of this pollution is attributable to AI because Google doesn’t break that out. (Also a problem!) So, what’s next and what does this all mean? 

Let’s start with fusion: Google’s deal with Commonwealth Fusion Systems is intended to provide the tech giant with 200 megawatts of power. This will come from Commonwealth’s first commercial plant, a facility planned for Virginia that the company refers to as the Arc power plant. The agreement represents half its capacity.

What’s important to note here is that this power plant doesn’t exist yet. In fact, Commonwealth still needs to get its Sparc demonstration reactor, located outside Boston, up and running. That site, which I visited in the fall, should be completed in 2026.

(An aside: This isn’t the first deal between Big Tech and a fusion company. Microsoft signed an agreement with Helion a couple of years ago to buy 50 megawatts of power from a planned power plant, scheduled to come online in 2028. Experts expressed skepticism in the wake of that deal, as my colleague James Temple reported.)

Nonetheless, Google’s announcement is a big moment for fusion, in part because of the size of the commitment and also because Commonwealth, a spinout company from MIT’s Plasma Science and Fusion Center, is seen by many in the industry as a likely candidate to be the first to get a commercial plant off the ground. (MIT Technology Review is owned by MIT but is editorially independent.)

Google leadership was very up-front about the length of the timeline. “We would certainly put this in the long-term category,” said Michael Terrell, Google’s head of advanced energy, in a press call about the deal.

The news of Google’s foray into fusion comes just days after the tech giant’s release of its latest environmental report. While the company highlighted some wins, some of the numbers in this report are eye-catching, and not in a positive way.

Google’s emissions have increased by over 50% since 2019, rising 6% in the last year alone. That’s decidedly the wrong direction for a company that’s set a goal to reach net-zero greenhouse-gas emissions by the end of the decade.

It’s true that the company has committed billions to clean energy projects, including big investments in next-generation technologies like advanced nuclear and enhanced geothermal systems. Those deals have helped dampen emissions growth, but it’s an arguably impossible task to keep up with the energy demand the company is seeing.

Google’s electricity consumption from data centers was up 27% from the year before. It’s doubled since 2020, reaching over 30 terawatt-hours. That’s nearly the annual electricity consumption from the entire country of Ireland.

As an outsider, it’s tempting to point the finger at AI, since that technology has crashed into the mainstream and percolated into every corner of Google’s products and business. And yet the report downplays the role of AI. Here’s one bit that struck me:

“However, it’s important to note that our growing electricity needs aren’t solely driven by AI. The accelerating growth of Google Cloud, continued investments in Search, the expanding reach of YouTube, and more, have also contributed to this overall growth.”

There is enough wiggle room in that statement to drive a large electric truck through. When I asked about the relative contributions here, company representative Mara Harris said via email that they don’t break out what portion comes from AI. When I followed up asking if the company didn’t have this information or just wouldn’t share it, she said she’d check but didn’t get back to me.

I’ll make the point here that we’ve made before, including in our recent package on AI and energy: Big companies should be disclosing more about the energy demands of AI. We shouldn’t be guessing at this technology’s effects.

Google has put a ton of effort and resources into setting and chasing ambitious climate goals. But as its energy needs and those of the rest of the industry continue to explode, it’s obvious that this problem is getting tougher, and it’s also clear that more transparency is a crucial part of the way forward.

Google’s recent unveiling of what it calls a “new class of agentic experiences” feels like a turning point. At its I/O 2025 event in May, for example, the company showed off a digital assistant that didn’t just answer questions; it helped work on a bicycle repair by finding a matching user manual, locating a YouTube tutorial, and even calling a local store to ask about a part, all with minimal human nudging. Such capabilities could soon extend far outside the Google ecosystem. The company has introduced an open standard called Agent-to-Agent, or A2A, which aims to let agents from different companies talk to each other and work together.

The vision is exciting: Intelligent software agents that act like digital coworkers, booking your flights, rescheduling meetings, filing expenses, and talking to each other behind the scenes to get things done. But if we’re not careful, we’re going to derail the whole idea before it has a chance to deliver real benefits. As with many tech trends, there’s a risk of hype racing ahead of reality. And when expectations get out of hand, a backlash isn’t far behind.

Let’s start with the term “agent” itself. Right now, it’s being slapped on everything from simple scripts to sophisticated AI workflows. There’s no shared definition, which leaves plenty of room for companies to market basic automation as something much more advanced. That kind of “agentwashing” doesn’t just confuse customers; it invites disappointment. We don’t necessarily need a rigid standard, but we do need clearer expectations about what these systems are supposed to do, how autonomously they operate, and how reliably they perform.

And reliability is the next big challenge. Most of today’s agents are powered by large language models (LLMs), which generate probabilistic responses. These systems are powerful, but they’re also unpredictable. They can make things up, go off track, or fail in subtle ways—especially when they’re asked to complete multistep tasks, pulling in external tools and chaining LLM responses together. A recent example: Users of Cursor, a popular AI programming assistant, were told by an automated support agent that they couldn’t use the software on more than one device. There were widespread complaints and reports of users canceling their subscriptions. But it turned out the policy didn’t exist. The AI had invented it.

In enterprise settings, this kind of mistake could create immense damage. We need to stop treating LLMs as standalone products and start building complete systems around them—systems that account for uncertainty, monitor outputs, manage costs, and layer in guardrails for safety and accuracy. These measures can help ensure that the output adheres to the requirements expressed by the user, obeys the company’s policies regarding access to information, respects privacy issues, and so on. Some companies, including AI21 (which I cofounded and which has received funding from Google), are already moving in that direction, wrapping language models in more deliberate, structured architectures. Our latest launch, Maestro, is designed for enterprise reliability, combining LLMs with company data, public information, and other tools to ensure dependable outputs.

Still, even the smartest agent won’t be useful in a vacuum. For the agent model to work, different agents need to cooperate (booking your travel, checking the weather, submitting your expense report) without constant human supervision. That’s where Google’s A2A protocol comes in. It’s meant to be a universal language that lets agents share what they can do and divide up tasks. In principle, it’s a great idea.

In practice, A2A still falls short. It defines how agents talk to each other, but not what they actually mean. If one agent says it can provide “wind conditions,” another has to guess whether that’s useful for evaluating weather on a flight route. Without a shared vocabulary or context, coordination becomes brittle. We’ve seen this problem before in distributed computing. Solving it at scale is far from trivial.

There’s also the assumption that agents are naturally cooperative. That may hold inside Google or another single company’s ecosystem, but in the real world, agents will represent different vendors, customers, or even competitors. For example, if my travel planning agent is requesting price quotes from your airline booking agent, and your agent is incentivized to favor certain airlines, my agent might not be able to get me the best or least expensive itinerary. Without some way to align incentives through contracts, payments, or game-theoretic mechanisms, expecting seamless collaboration may be wishful thinking.

None of these issues are insurmountable. Shared semantics can be developed. Protocols can evolve. Agents can be taught to negotiate and collaborate in more sophisticated ways. But these problems won’t solve themselves, and if we ignore them, the term “agent” will go the way of other overhyped tech buzzwords. Already, some CIOs are rolling their eyes when they hear it.

That’s a warning sign. We don’t want the excitement to paper over the pitfalls, only to let developers and users discover them the hard way and develop a negative perspective on the whole endeavor. That would be a shame. The potential here is real. But we need to match the ambition with thoughtful design, clear definitions, and realistic expectations. If we can do that, agents won’t just be another passing trend; they could become the backbone of how we get things done in the digital world.
