Runway Trains Robots Using Internet Videos, Performance Nearly Matches That From Professional Datasets

2026.10.01 22:41:19

Insight Beating AI News Flash: Runway has released the robot model Praxis-1, applying the expertise from training AI video models to real-world robots. It first learns how objects move and how humans perform tasks from a large number of regular videos, then translates that knowledge into robot movements. Runway conducted an object placement test: after pre-training with internet videos, the robot’s average error was 16.1 cm; when using custom-collected teleoperation videos of robots, the error was 16.0 cm. The test covered 93 evaluation sets, with results nearly identical across the two training approaches. If this line of work can be scaled, the data gap plaguing robot training could expand by several orders of magnitude. Collecting data via human-operated robot teleoperation requires specialized equipment, space, and labor, while regular videos are already abundant online. Runway aims to repurpose these videos—originally not intended for robot control—into training materials for robots to master movements. Praxis-1 has been tested on multiple robot models from Noble Machines, Standard Bots, and Ultra, including robotic arms, dual-arm robots, and mobile robots. Runway also showcased that the same strategy can adapt from a studio setting to a kitchen to complete tasks. The model is currently only accepting early test applications; its weights are set to be released in the coming months, with parameter size and more comprehensive independent evaluations still undisclosed.

ByteDance is in talks to acquire MediaTek's AI chips, while Qualcomm has previously secured orders for millions of such chips.

Insight: Beating AI Newsflash – ByteDance is in advanced negotiations with MediaTek to source custom ASIC chips for its data centers. Bloomberg reported on October 15, citing people familiar with the matter, that the two sides are close to a deal, though details including procurement volume, chip specifications, and delivery timeline remain undisclosed. If finalized, ByteDance would become MediaTek’s second major ASIC client after Google. This is not ByteDance’s first foray into securing data center chips from mobile chipmakers: in May this year, Bloomberg revealed the company had reached an agreement with Qualcomm to source millions of ASICs for powering AI Agents, with Qualcomm set to help bring ByteDance’s self-developed chip designs to production. The latest engagement with MediaTek signals ByteDance is expanding its custom chip supply channels to alleviate computing power pressure stemming from U.S. export restrictions and domestic chip capacity shortages. MediaTek, which previously focused primarily on its mobile processor business, has now entered Google’s TPU supply chain and begun competing with players like Broadcom and Qualcomm for data center orders. The firm projects its data center AI chip revenue will exceed $2 billion this year. In August, Nvidia also subscribed to $3.5 billion in MediaTek’s convertible bonds and announced a partnership to develop custom AI infrastructure. While such ASICs can optimize performance, power efficiency, and cost for specific tasks, it remains unconfirmed whether the chips ByteDance is negotiating to purchase will be used for model training or inference.
