Sony has published a patent application describing an AI-powered system designed to diagnose problems with consumer electronics and, in some cases, generate and remotely apply software fixes. Published as US 2026/0277732 A1 on September 17, the filing outlines a server-based system that receives diagnostic information from devices, uses AI models to determine whether corrective action is necessary and communicates with the affected hardware to address the issue. The application is titled “AI Self-Diagnostics for Consumer Electronics Devices.”
Sony Group Corporation filed the US application on March 14, 2025, with James R. Milne, Justin Kenefick, William Clay and Christopher Bjork listed as inventors. The system is not limited specifically to PlayStation hardware and is described broadly enough to cover multiple categories of consumer electronics. Patent illustrations and descriptions contemplate connected devices communicating with remote systems capable of analyzing technical problems and returning instructions.
One of the more unusual elements is the proposed use of a large language model to create diagnostic algorithms when a device reports an issue. Under one claimed implementation, a client device could notify a remote system of a problem, prompting an LLM to write diagnostic software tailored to investigate it. That code could then be transmitted back to the device, executed locally and used to provide additional information about what is malfunctioning.
The remote system could subsequently use AI models to determine whether corrective action should be taken. If a repair is required, Sony’s proposal allows the system to communicate with the affected device and initiate the corrective action. If intervention is not considered necessary, the issue could instead be logged and tracked, providing Sony with information about recurring faults across multiple devices.
The patent goes further by describing AI-generated software updates. If the same issue appears across enough client devices, a machine-learning model could infer a possible correction and a code generator could produce the software update needed to implement it. The filing specifically allows for that code generator to itself be an LLM, meaning both diagnosis and portions of the software-remediation process could potentially be generated dynamically rather than relying entirely on predetermined support procedures.
Sony also describes using fault data geographically. The system could track instances of an issue by region and, after identifying a recurring problem in one area, prepare corrective software for devices elsewhere before those users encounter the same fault. One example describes an LLM producing region-specific firmware code that could either be pushed to affected devices or presented to users as an available update.
That creates a system that is not simply reactive. Instead of waiting for every individual user to encounter a problem and contact support, Sony’s approach could use information collected from one group of devices to identify and potentially address the same problem elsewhere. The concept could theoretically reduce troubleshooting time and allow fixes to be distributed before a fault becomes widespread.
The application arrives as major technology companies increasingly explore AI for tasks extending beyond conversational assistants and content generation. Microsoft, for example, has also recently detailed experimental technologies through patent filings, including a context-aware in-game advertising system designed around events occurring inside interactive software. In Sony’s case, the focus is instead on maintaining connected hardware and automating parts of technical diagnosis and remediation.
There are important limitations to what the filing establishes. A patent application describes technology Sony has sought to protect, not a confirmed feature planned for PlayStation 5, a future PlayStation console, Sony televisions or any other commercial device. The document also does not provide a release schedule or indicate that Sony has begun deploying AI-generated repair code to consumer hardware.
Automatically generating and distributing diagnostic or corrective software would also require safeguards beyond the high-level process described in the filing. Incorrectly generated code could itself introduce problems, while any remote system capable of initiating changes on consumer devices would need strict security and validation controls. The patent primarily establishes the technical framework Sony is exploring rather than detailing how those operational risks would be managed in a finished consumer service.
For now, US 2026/0277732 A1 provides a look at how Sony is considering AI as part of future device support infrastructure. The central idea is a connected system capable of detecting faults, generating its own diagnostic tools, identifying corrective action and potentially distributing software fixes across affected hardware with considerably less manual troubleshooting.
