Simular has made Sai, its computer use agent, generally available. Sai can now run computers autonomously for hours, spawn helper agents, and scale work across 100 machines in parallel for less than $1
Palo Alto, United States, September 23, 2026 -- Simular, the autonomous computer company, announced the general availability of Sai, its computer-use agent, at sai.work. Sai can spawn a fleet of autonomous computers that execute tasks on multiple machines simultaneously, furthering the company’s mission to free people from laborious, repetitive digital work.
Sai operates computers directly: it reads screens, clicks, types, navigates applications, and plans what to do next. Users can assign work to one or multiple computers, monitor progress remotely, and receive a notification when the work is complete. Sai was invite-only before its general availability.

The company introduces #SaiFleet as a new paradigm for computer-use agents: instead of one AI agent operating one computer at a time, users can deploy fleets of autonomous computers to work in parallel.
Because Sai works through the computer interface rather than integrations, it can operate software that has no application programming interface (API), including legacy desktop applications and internal portals behind a login. It runs on Windows, macOS and Linux, either on a cloud-based virtual machine (VM) that Simular provisions or on the user's own device. Users can watch any computer in the fleet while it works and take back control of the mouse during a run. Sai asks for permissions on critical actions, and results arrive through iMessage, SMS or Telegram.
Sai is available now at sai.work, starting free with options for pay-as-you-go, unlimited access, and enterprise-grade scaling and security.
To demonstrate Sai’s ability to handle long, complex computer tasks, the company streams the agent playing Minecraft live. Sai played autonomously for 14 hours, without step-by-step human intervention. It read the game screen, decided what to do next, and spawned helper agents: including Jev, to handle tasks like mining while the main agent continued working on other objectives.
Sai completed eight of fifteen goals in the session, costing approximately $0.01 per hour. That means the #SaiFleet can run 100 computers in parallel for less than $1 in total, opening the possibility of autonomous fleets performing hundreds of tasks simultaneously, from research and data entry to browser workflows, software testing, operations, and other repetitive digital labor.
“We believe the future of computer use is not one agent doing one task, but autonomous computers working together at scale,” said Ang Li, CEO and cofounder of Simular. “Our goal is to make digital labor faster, cheaper, and increasingly accessible so people can spend their time on the things only humans can do.”
Agents often rely on large language models to reason through every step of a task. For repetitive workflows, that can make automation expensive and slow.
Sai takes a different approach. Its neuro-symbolic architecture uses AI models to determine how a task should be completed, then it compiles the resulting procedure into executable scripts. When the same workflow runs again, Sai replays the code rather than reasoning through every step from scratch. If the interface changes, Sai returns to the base model for planning as part of a self-optimization mechanism.
Completed workflows can be saved as skills, scheduled to run automatically, or triggered by events. According to Simular's measurements, this approach reduces token consumption by at least 90% on long-horizon office tasks that repeat many times.
Sai is designed to operate without requiring users to supervise every click.
The system includes tiered approval controls, allowing users to grant trust for an individual task or workflow. Passwords and verification codes can be entered through encrypted input so that sensitive credentials are not exposed to the underlying model.
This allows Sai to move beyond chat-based assistance toward unattended digital work.
Sai ranked #3 Product of the Day on Product Hunt on September 21, 2026. On OSWorld 2.0, an industry leading benchmark of 108 long, multi-step, real computer tasks, Simular reported a 73.0% partial score for Sai in August 2026, ahead of Anthropic and OpenAI. In December 2025, Simular's open-source Agent S framework reached 72.6% on the original OSWorld benchmark, making it the first agent to reach the human baseline of 72.36%.
Simular is a research-driven company building accessible intelligence to free humans from digital labor. Its flagship agent Sai automates workflows by controlling local and cloud computers. Agent S, its open-source agentic framework, was the first to achieve human-level performance on the OSWorld computer-use benchmark. The company was one of five companies to pilot Microsoft's Windows 365 for Agents. Founded in 2023 by former Google DeepMind researchers, Simular is backed by investors including Felicis, Nvidia’s NVentures, South Park Commons, Basic Set, and Lenny Rachitsky.

SEATTLE — Alaska Airlines is looking to expand its presence in Asia as its Incheon-Seattle route gains traction, with Korea emerging as a key market in the U.S. carrier’s expanding international network. The airline recorded load factors of 82 percent in June, 84 percent in July and 79 percent in August on the route, marking a strong start in its first full year of operations. The figures exceeded expectations for a new route, which typically takes about three years to mature as the airline adjusts schedules and connections to meet passenger demand. "Those are really good, strong load factors for the first year of a new route," Shane Tackett, president and chief financial officer of Alaska Airlines, said in an interview with The Korea Times on Sept. 29. He added that one month ranked among Alaska's best-performing international routes financially before fuel prices increased significantly. The airline sees further opportunities to attract passengers from Korea, where its brand remains relatively unfamiliar. Tackett said Alaska Airlines aims to raise awareness of its services and enco
Hyundai Motor’s weakening auto profitability is raising questions about the sustainability of its costly investments in robotics and autonomous driving, as the technologies remain years away from generating significant earnings. The company is betting on Boston Dynamics’ Atlas humanoid robot, its own software-defined vehicle (SDV) and autonomous driving capabilities as three core pillars for its future mobility. Yet those businesses are far from generating tangible earnings, leaving Hyundai increasingly dependent on its conventional auto business which faces mounting earnings pressure from labor disputes at home, tariffs from the United States and intensifying competition from Chinese automakers in Europe. The timing gap between its weakening core business and future growth engines is becoming harder for investors to overlook. Hyundai’s shares have fallen around 60 percent from their June 1 peak of 783,000 won ($587) to less than 320,000 won on Monday, reflecting fading enthusiasm for its robotics ambitions and growing doubts over its earnings outlook. The pressure continues to be
Best known for turning sheet masks into a beauty routine staple, L&P Cosmetic’s Mediheal is building its next stage of growth around a broader portfolio of skin care solutions, ranging from toners to serums, cleansers, creams and sun care products. The expansion reflects Mediheal’s evolution from a mask-focused label into a comprehensive skin care brand designed to address consumers’ needs across every step of their daily routines. Drawing on the recognition it has built through sheet masks, the brand is extending its ingredient expertise and research capabilities into products that can be used before, after and alongside masks. That strategy was on display in Japan in August when Mediheal introduced its new Derma Skin Care Series, featuring toners, serums and serum masks. The series used three ingredients closely associated with the brand: tea tree, madecassoside and polydeoxyribonucleotide, better known as PDRN, an ingredient now gaining attention in the skin care market. The series' launch marked another major transformation for the brand since its entry into Japan with its mas
A constellation of five Korean microsatellites successfully captured and transmitted its first images to a ground station within a day of launch aboard the country's homegrown Nuri space rocket last week, the space agency said Thursday. The five New-space Earth Observation Satellite Constellation for National Safety (NEONSAT) microsatellites transmitted their first images just 14 hours and 29 minutes after liftoff from the Naro Space Center in the southwestern coastal town of Goheung on Oct. 7, according to the Korea AeroSpace Administration (KASA). The early acquisition of imagery confirmed the normal operation of the satellites and their optical payloads, marking a milestone in Korea's efforts to establish its first domestically developed microsatellite constellation. The satellites are maintaining stable communications with ground stations, with their power generation and attitude control systems operating normally, KASA said. Following additional payload checks, KASA and the Korea Advanced Institute of Science and Technology (KAIST) will begin initial operations. The five satellites
Korean steelmaker POSCO and shipbuilder Hanwha Ocean are teaming up to build a demonstration liquified natural gas (LNG) carrier equipped with high-manganese steel cargo tanks, aiming to strengthen Korea’s technological competitiveness in a market long dominated by foreign technology. LNG fuel tanks store the fuel used to power LNG-fueled vessels, while cargo tanks on LNG carriers are large storage systems that hold the LNG itself for transportation overseas. According to POSCO, the two companies signed a memorandum of understanding (MOU) at the shipbuilder’s Geoje shipyard to develop the demonstration vessel. The signing ceremony was attended by senior executives from both sides, including POSCO President Lee Hee-geun and Hanwha Ocean CEO Kim Hee-cheul. The partnership comes amid expectations of rising LNG demand as countries seek lower-carbon energy sources, fueling demand for LNG carriers. Korean shipbuilders, however, remain dependent on foreign technology for cargo tanks, a key component of the vessels. Under the MOU, the companies will develop cargo tanks using POSCO’s high-m
A recent hacking incident involving commercial refrigerators at supermarkets in France is highlighting the importance of cybersecurity for connected equipment among Korean businesses, as companies increasingly rely on interconnected and centrally controlled systems for their operations. Industry officials said Thursday that the attack compromised supermarket refrigeration systems, but the underlying issue is the growing reliance of commercial equipment on network connectivity. They stressed the need to strengthen security across both hardware and software to ensure that no loopholes emerge anywhere in the system. The incident affected hundreds of supermarkets in France, where hackers reportedly gained remote access to centralized refrigeration control systems and manipulated temperatures, forcing retailers to discard spoiled food. Danish manufacturer Danfoss, which supplied the affected systems, attributed the incident to outdated equipment that had not received security updates. Retail chains, including supermarkets, use commercial refrigeration equipment. In Korea, major electronics c
Hanwha Systems' laser air defense weapon Cheongwang successfully intercepted three out of three target drones in a live-fire demonstration, highlighting the company's efforts to expand its presence in the global air defense market. The company said Thursday that Cheongwang, also known as the Laser Air Defense Weapon Block-I, and a vehicle-mounted high-energy laser cannon intercepted the drones during the Army’s Army TIGER+ integrated combat exercise in Yangpyeong, Gyeonggi Province, on Wednesday. About 500 people attended the exercise, including the Army chief of staff, military officials, academics and industry experts. Cheongwang and the 30-kilowatt-class vehicle-mounted laser cannon achieved a 100 percent interception rate against the three drones. Small, low-cost unmanned aerial vehicles (UAVs) have emerged as growing battlefield threats, serving both reconnaissance and surveillance purposes and as attack weapons. Laser weapons are gaining attention as next-generation air defense systems capable of countering drone swarms while addressing some limitations of conventional missile-b
Shinhan Financial Group is seeking to bolster its nonbank operations by acquiring Lotte Insurance, but analysts cautioned Thursday that a meaningful contribution to group earnings may take time, as the insurer could require substantial additional capital to strengthen its financial position. Concerns over the cost of the deal weighed on Shinhan shares, which plunged 4.31 percent Wednesday following Tuesday’s announcement and fell a further 0.84 percent Thursday. The group agreed Tuesday to purchase a 77.04 percent stake in Lotte Insurance from private equity firm JKL Partners for 693.3 billion won ($514.6 million). After securing regulatory approval, it plans to acquire the remaining shares and eventually merge the insurer with its existing subsidiary, Shinhan EZ General Insurance. Lotte Insurance has 14 trillion won in assets and 3.34 million customers, giving Shinhan a substantially larger foothold in non-life insurance. The financial group aims to raise annual profit from the business to at least 120 billion won within three years. But market analysts warned that the insurer’s wea
The Financial Services Commission’s (FSC) planned relocation to the administrative city of Sejong next year is raising concerns across the financial industry about potential disruptions to communication with regulators and the resulting operational inefficiencies, industry officials said Thursday. Industry officials are particularly concerned that the move could make it harder for banks and securities firms, most of which are headquartered in Seoul, to consult financial authorities on regulatory matters. The country's top financial regulator, currently based in Seoul, plans to move to Sejong, about 110 kilometers to the south, in the second half of 2027. The move is part of a broader government plan to relocate 44 central government agencies and affiliated bodies from the Seoul metropolitan area to Sejong between 2027 and 2031, aiming to decentralize functions concentrated in the capital area and promote regional growth. Banks are weighing how to adapt, with some expecting to rely more heavily on remote communication. "We expect to establish ways to respond, including expanding the use
QUVASOY, Uzbekistan — Hansae Mobility, a Korean automotive parts manufacturer supplying global carmakers, has expanded its overseas production capacity with the completion of a new plant in Quvasoy, in Uzbekistan's Fergana Region. Hansae Yes24 Group's automotive parts subsidiary held a completion ceremony for the plant Tuesday (local time) in a free economic zone in Quvasoy. The facility is operated by Hansae Mobility Turan, an Uzbekistan subsidiary wholly owned by Hansae Mobility. The ceremony was attended by Hansae Mobility CEO and Hansae Vice Chairman Kim Ik-whan, Mirzohid Murodilovich, deputy governor of Fergana Region, and other officials and representatives from Korea and Uzbekistan. The plant is expected to enable Hansae Mobility to supply its products more quickly to clients in Uzbekistan and expand its customer base in neighboring countries across the Commonwealth of Independent States (CIS). Before the plant opened, Hansae Mobility had to export the parts from Korea. The new facility adds to the company's existing manufacturing bases in Daegu, the U.S. state of Michigan and t
