Startups Launch 'Airbnb for AI Inference' to Rent Your Idle Gaming PC for Passive Income

Cash in on the AI Boom by Renting Out Your Spare Compute

Computer hobbyists already have small server racks in their basements and garages -- now they can rent them out for AI inference and earn some passive income. If you own an at-home server, a gaming computer, or just a laptop that doesn't get much love, listen up. You can now put that spare computing power to use and earn some passive income in the process. AI companies are hungry for more compute to run AI inference -- the process of using a pre-trained model to respond to queries -- and they're willing to pay you for it. "Imagine Uber or Airbnb, but for AI inference computing tasks," says Ilman Shazhaev, founder and CEO of Far Labs, based in Abu Dhabi. The AI boom has spurred on construction of massive data centers, often damaging local communities by raising electricity prices, straining local water resources, causing environmental damage and noise, and being just plain ugly. Huge data centers are likely not going anywhere -- training new frontier models and running AI models from leading companies will likely still be the purview of these behemoths. But now, several companies are providing AI inference on smaller, mostly open-source models. They are running inference on pre-existing computing power spread throughout homes and small businesses, and compensating owners. "Everyone thinks the only way to do it is data centers. And data centers are extractive for the communities in which they're built, and they don't return services or taxes or much of anything to the people there. So why not just turn this whole thing on its head?" says John Federico, founder and CEO of Evolving Edge, in Austin, Texas. "The compute power is out there. If you can orchestrate it, then you're actually adding value to those communities directly." The idea isn't entirely new: From 1999 to 2020, a volunteer-based project called SETI@Home used spare computers to search for signs of extraterrestrial life in radio telescope data, for instance. But now, commercial companies are eager to use the same strategy. Shazhaev's Far Labs is launching its platform Far AI in the coming weeks, while Federico's Evolving Edge is currently in open beta. Other companies, like Bless Network, Salad, and Gradient have started to provide similar platforms over the last year. Connecting to the network Federico has been a computer hobbyist since youth, and he has amassed a whole server in his basement to run his projects. "It just hit me one day, there's all this talk about not having enough compute, and I just thought, well, 92 percent of the country has broadband, and you have people like me who have mini data centers in a closet," he says. Federico sees the potential hosts as people much like himself who have already invested in home servers, and he aims to make the process of selling spare compute as seamless for them as possible. "Sign up for the program, install an application," Federico says. "All we want to do is run jobs on your machine when you tell us we're allowed to. The only thing we do is monitor the resource usage. And of course, you can give us a schedule." With a large enough network of devices, the platform would have compute available whenever it's needed. Privacy and security are primary concerns for such hosts. To reassure the users that their local data is secure, and that no malware will be downloaded to their devices, the team open-sourced their scheduling software. "The node software is open source, so anyone can look at it, see what it does. All we want to do is run jobs on your machine when you tell us we're allowed to," Federico says. Far Labs' Shazhaev explains that the company's software is designed around a principle known as "least privilege": granting both the host and the user the least access possible to accomplish the task. Inference runs as an isolated workload with authenticated, encrypted communication and explicit limits on the GPU, CPU, memory, storage, and network resources it may use. Customers do not receive arbitrary access to the host machine, and providers can inspect resource use, pause the node, revoke access, and remove the software at any time. The protection also works in the other direction. Workloads are segmented and only the minimum required information is exposed to an individual node. Sensitive enterprise workloads can be restricted to controlled hardware rather than routed through consumer devices. Divide and conquer Massive data centers still have advantages from the user perspective: top of the line GPUs and CPUs, high speed networking, thick cables, and sophisticated cooling. User devices are usually less powerful, more varied, and less reliably connected to one another. "This is quite a difficult issue from the science angle," Shazhaev says. "You want to do a similar level of tasks that are happening in those high infrastructure data centers, and run them on the user device with limited capacity." Evolving Edge's Federico says this is an issue for the largest, state-of-the art AI models. But those are not always needed and are often not even preferred. "There are numerous companies, once they reach a certain scale, suddenly paying for tokens on a state-of-the-art frontier model [that] no longer makes sense for their needs," he says. "Instead, they are fine-tuning open-source models for specific tasks that they have in their business. These models don't require anywhere near the resources that some of the state-of-the-art models do. It's just using the right tool for the job." Smaller, open-source models can often fit on a single user device. But if that fails, there are tools to split a single inference task over multiple GPUs or CPUs. Evolving Edge is using an open-source tool called Ray to perform this splitting, while Far Labs has developed its own proprietary software that not only splits the workload, but wraps the splitting in a layer of security and reliability-providing software. "One thing we have done is we shared the model," Shazhaev says. "We take the model, we cut it into many pieces, then these pieces will be distributed through different devices. And we have an orchestrator and a load balancer which manage the task flow, so each device processes a part of the task. Then we combine the answers in the main brain, the orchestrator." Through a combination of using smaller, more task-specific models, and splitting larger models between disparate devices, the teams claim they can perform inference much cheaper than a traditional data center "because we don't have capital expenditure," Shazhaev says. The distributed advantage Not only is it cheaper to run inference this way, it is also more reliable, Shazhaev claims. The companies have access to a distributed network of computing resources, rather than one giant device that can experience outages. Shazhaev compares this to cryptocurrencies, and their resilience through decentralization. "Today, to shut down Bitcoin, you need to nuke the whole planet. Here, we have the same concept," Shazhaev says. Federico explains that this resiliency would be beneficial not just for AI inference, but for all kinds of applications, including smart cities, environmental sensors, autonomous vehicles, and more. During an Amazon Web Services outage in 2026, for example, smart beds were stuck in their upright positions and their users couldn't adjust them. Federico says that a distributed network where everything doesn't need to be routed through a single data center, say, in Ashburn, Va., would make those kinds of outages much less impactful. "We could lose 100 nodes in a network of 250,000 and it wouldn't matter," he says. If the network of user devices is substantial enough, every job can be routed to a nearby device, decreasing the latency. Far Labs claims a latency of 100 milliseconds or less on its platform. The lower cost and lower latency of this approach may even enable new use cases, such as in-game AI video generation, which is currently prohibitively slow and expensive. "OpenAI last year had $30 billion in revenue, but they closed the financial year at an $8 billion loss. Why? The official reason is due to the high cost of inference," Shazhaev says. "And those are mostly text models. For gameplay, you have audio, video, animations: It's heavy data, and you need real-time responses. So, we've been trying to solve this issue." All of these companies are trying to tap into an untapped resource of local compute, and hoping it'll benefit the device hosts and users alike. "All these big guys are running around building data centers," Shazhaev says, "but I believe there is enough compute power that already exists in the world."

Startups want to rent your idle gaming PC for AI tasks -- Startups pitch an 'Airbnb for AI inference,' but profitability remains unproven

If, like mine, your gaming rig spends most of its life doing nothing these days, a pair of startups would be willing to pay you something close to minimum wage for its downtime. Abu Dhabi-based Far Labs and Austin-based Evolving Edge are building marketplaces to farm AI inference out to idle consumer hardware, according to an IEEE Spectrum report. Far Labs plans to launch its Far AI platform in the coming weeks, claiming latency of 100 ms or less, while Evolving Edge is running an open beta. "Imagine Uber or Airbnb, but for AI inference computing tasks," Ilman Shazhaev, founder and CEO of Far Labs, told the outlet. Both companies are targeting smaller open-source models rather than frontier-scale workloads, and they're joining established players, including the Utah-based Salad platform, which lists more than 60,000 daily active consumer GPUs on its network. Far Labs' proprietary scheduler splits a model into pieces spread across multiple machines, and an orchestrator and a load balancer then reassemble the partial outputs into a response. Evolving Edge distributes jobs with Ray, the open-source framework used inside conventional data centers. Letting a stranger's workload onto a personal machine obviously comes with some risks for hosts, such as malicious code ending up on the device or the person on the other end gaining access to local files. The two firms' solution to this is isolation, with inference running as a sandboxed workload with encrypted communication and hard limits on GPU, CPU, memory, storage, and network access. Customers get no direct access to the host machine, and Evolving Edge has open-sourced its node software so hosts can audit what runs on their hardware. Salad sells consumer-GPU compute to customers for prices starting at $0.02 per hour, and the card's owner only sees a slice of that... pie after the platform takes its cut. We examined Salad in 2021, back when its network mined Ethereum, estimating that the company had generated roughly $3.6 million from users' PCs while distributing $500,000 in rewards, which works out to about 14 cents on the dollar for the people supplying the silicon. Electricity costs then chew through whatever's left. An RTX 4090 draws 350W to 450W under sustained load, roughly $40 to $50 a month at $0.15 per kWh if the card runs around the clock, so a rig earning less than that is effectively paying for the privilege of having a job. However, IEEE Spectrum's report doesn't include payout rates for either new platform. Both founders make the point that distributed networks ride out failures that otherwise cripple centralized clouds. John Federico, founder and CEO of Evolving Edge, cited the AWS outage last October that left Internet-connected smart beds stuck in their upright positions, and told IEEE Spectrum his network could lose 100 of 250,000 nodes "and it wouldn't matter." All that aside, distributed AI compute has a credibility problem to overcome. A research preprint from June claimed that Pearl, a blockchain marketed as converting cryptocurrency mining into AI work, ran the equivalent of 320,000 RTX 3090-class GPUs on random matrix math while producing no useful AI computation. Far Labs and Evolving Edge route real customer inference jobs rather than token rewards, which puts them a step ahead of that model, but their cost and latency figures are unsubstantiated claims until, and if, the networks operate at scale.
