China’s latest neuromorphic project has pushed a once speculative idea into the realm of claimed reality: a monkey’s brain activity, recreated inside a supercomputer. The country’s researchers say they have built a machine that mimics a primate mind closely enough to run an artificial version of a macaque brain, raising profound questions about what it means to “upload” an animal’s cognition. The result is a collision of neuroscience, artificial intelligence, and geopolitics that is already reshaping how I think about the future of computing.
At the center of this story is a system called Darwin Monkey, a brain-inspired computer that Chinese teams describe as capable of simulating primate-level intelligence. Their work builds on years of experiments that linked living monkey brains to machines and now extends into a vast neuromorphic platform designed to behave like a monkey’s mind at scale. Whether that amounts to a genuine brain upload or a sophisticated imitation is still contested, but the technical and ethical stakes are no longer hypothetical.
From brain–computer links to claims of a digital monkey mind
The idea that a monkey’s brain could be mirrored inside a machine did not appear overnight. Chinese researchers had already been working on direct brain–computer links, and by May 5, 2023 they were publicly describing a “world first” experiment in which a monkey’s brain signals were synchronized with a computer in a controlled lab setting. In that work, teams in China claimed to have successfully conducted a non-invasive brain–computer interface that let a primate interact with a machine through neural activity alone, a foundational step toward any later talk of “uploading” cognition.
That early experiment, described again through a separate account of how China syncs monkey brain activity with a computer at Xuanwu Hospital Capital Medical University, showed that neural signals could be captured and translated into digital commands in real time. I see that as the biological half of the story: a living macaque sending information outward to silicon. The newer claims about a monkey brain “on” a supercomputer flip the direction of travel, suggesting that a digital system can now run an internal model of a primate mind, not just listen to one.
Darwin Monkey, Wukong, and the race to build a brain-like supercomputer
To host anything resembling a brain upload, China needed hardware that behaves less like a traditional server rack and more like a nervous system. That is where Darwin Monkey, also referred to as Wukong, comes in. Reports describe it as a brain-inspired supercomputer that Chinese teams unveiled over the summer, with one account on Aug 27, 2025 describing China, Darwin Monkey, Wukong as the world’s largest brain-inspired system, built around 100 billion synapses. That figure, 100 billion, is not accidental; it is meant to echo the scale of connections in a primate brain and signal that this machine is designed to operate at biological complexity, not just raw floating-point throughput.
Other coverage reinforces that framing. One detailed description of the platform on Sep 3, 2025 characterizes it as China Unveils, Darwin Monkey, The World, Largest Brain, Inspired Supercomputer, emphasizing that Chinese researchers see it as the most ambitious brain-like computer ever constructed. A companion account, also tied to Sep 3, 2025, repeats that Sep, China Unveils, Darwin Monkey, The World, Largest Brain, Inspired Supercomputer label, underscoring how central the “largest” and “brain-inspired” claims are to the project’s identity. In that context, a monkey brain upload is less a stunt and more a flagship demonstration of what this neuromorphic architecture is supposed to do.
A computer that “thinks like a monkey”
Chinese engineers have not been shy about describing Darwin Monkey in cognitive terms. On Aug 3, 2025, officials in Hangzhou said that Chinese engineers on Saturday unveiled a new generation of brain-like computer, explicitly “dubbed Darwin Monkey,” that can mimic the thinking patterns of a primate. That description, that it can “think like a monkey,” is central to the way the system is being marketed, and it appears in a government-linked account that highlights how Chinese, Saturday, Darwin Monkey are being positioned as a showcase for the country’s brain-inspired computing ambitions.
Another technical report, dated Aug 2, 2025, describes the same platform as the World’s largest-scale brain-like computer with 2 billion neurons, capable of running intelligent applications on the computer while consuming relatively low power under typical operating conditions. That account stresses that engineers in China unveiled a system with 2 billion neurons and 100 billion synapses, a configuration that again mirrors the scale of a primate cortex. When I put those descriptions together, the “thinks like a monkey” line looks less like hype and more like a shorthand for a very specific design goal: to reproduce the statistical and structural properties of a macaque brain in silicon.
Inside the “brain-like” architecture: 2 billion neurons and 100 billion synapses
Under the hood, Darwin Monkey is not a conventional supercomputer that simply stacks more GPUs. It is a neuromorphic system built around pulsed neurons and synapses that fire in patterns closer to biological spikes than to standard digital logic. One technical overview on Aug 3, 2025 explains that the machine was Developed, Zhejiang University, China, Zhejiang Province by the national key lab of brain intelligence at Zhejiang University in east China’s Zhejiang Province, and that it contains 2 billion pulsed neurons and 100 billion synapses. Those numbers are not just impressive on paper; they are chosen to approximate the density and connectivity of a primate brain, which is why the system is being pitched as a platform for brain science research rather than just another AI accelerator.
Another account, tied to Aug 27, 2025, reinforces that scale by describing 100 billion synapses as a defining feature of the Darwin Monkey or Wukong system. When I read those figures alongside the earlier description of 2 billion neurons, the architecture looks like a deliberate attempt to match the order of magnitude of a macaque brain, which is often estimated in the billions of neurons. That is why claims of a monkey brain upload, while still unverified based on available sources, are at least technically anchored in a machine that has been built to operate at the right scale and with the right kind of spiking dynamics to host a detailed neural model.
From “AI version of a monkey’s brain” to talk of uploads
The leap from neuromorphic hardware to a claimed brain upload came into focus in early August, when Chinese researchers began describing an “AI version of a monkey’s brain” running on a computer. On Aug 3, 2025, one widely shared summary put it bluntly, saying that it is not science fiction and that Aug, Chinese researchers had created an AI version of a monkey’s brain and put it on a computer. That phrasing is what fuels the “upload” narrative, because it suggests that the system is not just inspired by primate cognition but is meant to be a direct artificial counterpart of a specific animal’s neural organization.
Another detailed analysis on Aug 6, 2025 goes further, describing Aug, China, Brain, Inspired, Darwin Monkey, Breakthrough Simulates Primate level intelligence and noting that Chinese researchers have revealed a system modeled on a type of monkey called a macaque. That account frames Darwin Monkey as a brain-inspired AI breakthrough that simulates primate-level intelligence, not just generic pattern recognition. I read that as a crucial distinction: the researchers are not claiming to have copied a particular monkey neuron by neuron, but they are asserting that their model captures the functional organization of a macaque brain closely enough to behave like a digital primate mind.
Neuromorphic supercomputing as strategic technology
Beyond the scientific drama, Darwin Monkey is also a geopolitical signal. China has been explicit about its ambition to lead in brain-inspired computing, and the scale of this project reflects that. A report dated Sep 7, 2025 states that Sep, China Builds World, Largest Neuromorphic Supercomputer, Darwin Monkey, China and that the country has just unveiled what it calls the world’s largest neuromorphic supercomputer. That description casts Darwin Monkey as a “giant step” in a broader journey toward machines that process information the way brains do, and it positions China as a frontrunner in a field that blends AI, neuroscience, and specialized hardware.
Earlier coverage on Sep 3, 2025, which labels the system as Sep, China Unveils, Darwin Monkey, The World, Largest Brain, Inspired Supercomputer, reinforces that strategic framing. When I connect those dots, the monkey brain narrative looks like part of a larger push to showcase neuromorphic computing as a domain where China can claim clear firsts, from synchronizing a monkey brain with a computer to running a primate-level AI on a dedicated brain-like machine. The technical details matter, but so does the message: this is a frontier technology that Beijing wants the world to associate with its labs and universities.
What “upload” really means in this context
For all the dramatic language, it is important to be precise about what has and has not been demonstrated. The available reporting describes a progression from non-invasive brain–computer interfaces with live monkeys to a neuromorphic supercomputer that can simulate primate-level intelligence using 2 billion neurons and 100 billion synapses. None of the sources explicitly confirm that a specific monkey’s brain has been scanned and reconstructed neuron by neuron inside Darwin Monkey, so any claim of a literal, individual brain upload remains unverified based on available sources. What is documented is the creation of an AI version of a monkey’s brain that runs on a computer and behaves like a macaque mind in key respects.
In that sense, “upload” here is closer to a functional emulation than to the science fiction idea of transferring a unique consciousness. The Aug 3, 2025 description of an AI version of a monkey’s brain and the Aug 6, 2025 account of a brain-inspired breakthrough that simulates primate-level intelligence both point to a model that is trained or configured to reproduce macaque-like cognition, not to a one-to-one digital twin of a particular animal. That distinction matters ethically and philosophically, but it does not diminish the technical achievement: building a machine that can host such a model at biological scale is still a profound step toward more brain-like AI.
Potential uses, from neuroscience to military and surveillance
Once a country can run a primate-level brain model on a neuromorphic supercomputer, the range of possible applications widens quickly. On the benign side, Chinese teams have framed Darwin Monkey as a tool for brain science, with the Aug 3, 2025 technical overview noting that the system, Developed at Zhejiang University, opens new possibilities for brain science research. A machine that can mimic a monkey’s mind could help neuroscientists test hypotheses about cognition, memory, and disease in silico before moving to animal experiments, potentially reducing harm and accelerating discovery.
At the same time, a system that can simulate primate-level intelligence at scale is inherently dual use. The same architecture that supports brain research could be adapted for autonomous drones, advanced surveillance, or decision-support systems that operate more like biological agents than like traditional software. The earlier work in which Chinese researchers synchronized a monkey brain with a computer already hinted at military and medical applications for brain–computer interfaces. Now, with Darwin Monkey, the focus shifts to what happens when the “brain” on the other end of that interface is itself an artificial primate mind running on a state-backed supercomputer.
Ethical and global implications of a digital primate brain
Even if the current system is “only” an AI version of a monkey’s brain, the ethical questions are immediate. If a neuromorphic computer with 2 billion neurons and 100 billion synapses can simulate primate-level intelligence, at what point does that simulation deserve moral consideration? The Aug 6, 2025 description of a Breakthrough Simulates Primate intelligence suggests that the model is not just a toy network but a system capable of complex behavior. If such a model can experience something like frustration, curiosity, or fear, then running it purely as a computational experiment starts to look less like engineering and more like digital animal testing.
There is also a global governance dimension. By branding Darwin Monkey as the World’s Largest Brain-Inspired supercomputer and as the world’s largest neuromorphic platform, China is effectively setting the pace for how far and how fast this technology advances. Other countries will face pressure to respond, either by building their own brain-like machines or by pushing for international norms that limit how such systems can be used. For now, the monkey brain upload narrative is a vivid symbol of that race: a reminder that the line between biological and artificial minds is becoming less clear, and that the decisions made in a few labs in Zhejiang Province and Beijing could shape the cognitive infrastructure of the twenty-first century.
