Wasm I/O 2025 - Barcelona, 27-28 March Slides: https://2025.wasm.io/slides/privacy-preservation-with-smarter-automotive-experiences-wasmio25.pdf Taira Automotive is a privacy-preserving service that orchestrates intelligence across global fleets of vehicles by using edge networks in over 100 data centers. Using WebAssembly we deploy intelligence workloads instantly to large fleets, distributing training and inference across both Nvidia and Intel platforms, without the need to collect or aggregate data. Each vehicle trains on its own data, and runs inference, enabling offline services to be smarter and responsive, whilst benefiting from significant cost efficiencies and sustainability improvements. Our demo showcases the platform running on mobile, in-vehicle, and across the edge network, using a variety of WebAssembly runtimes, whilst complying with global data regulations, across borders, with safety and privacy preserved. This is a step forward from the original talk: “From Event-Driven to Automotive”, focusing on a single use case.
