Synaptics’ edge-AI strategy is about running more AI inference on the device itself, rather than sending every request to a data center. The idea was outlined in 2022 by then-CEO Michael Hurlston and developed into a broader platform strategy under CEO Rahul Patel, with Astra as its current compute-platform anchor.
What does AI at the edge mean?
Edge AI runs a machine-learning model on a device near where data is created—such as an IoT product—instead of relying on a remote data center for each inference. In a December 21, 2022 interview, then-Synaptics CEO Michael Hurlston said the company wanted to “make decisions on the chip” rather than return to the data center for high compute and bandwidth. The interview linked that approach to reducing security exposure by keeping more decisions local.
Local inference can reduce the delay and network traffic associated with cloud round trips, and can limit how much data leaves a device. It does not eliminate the need for cloud services: more demanding workloads may exceed an edge device’s compute, memory, or power budget.
How Synaptics’ strategy has changed
Hurlston’s 2022 vision
Hurlston described Synaptics’ acquisition of Emza and the Katana chip as part of its effort to bring AI to edge devices. Katana was described as supporting presence detection, privacy mode, and environmental sensing through visual, audio, and other environmental inputs. These were examples of on-device use cases, not a claim that every AI workload could run locally.

Patel’s broader 2025 strategy
Rahul Patel is the CEO in Synaptics’ 2025 source record. In a July 2, 2025 post, Patel described a strategy that combines processors capable of on-device machine-learning inference with Wi-Fi, Bluetooth, touch, audio, and fingerprint capabilities. He said Synaptics aims to provide “full Edge AI solutions” across end applications, moving beyond standalone components toward a combination of processing, connectivity, sensing, and software.
What is the Astra platform?
Synaptics describes Astra as an AI-Native embedded compute platform for multimodal IoT workloads. Its stated ingredients include scalable, low-power edge silicon, open-source tools, wireless connectivity, and support for multiple input types. The goal is to give developers a base for building products that can interpret information such as images, sound, and other contextual signals locally.

On January 2, 2025, Synaptics announced a collaboration to integrate Google’s ML core with Astra hardware and open-source software. The announcement named vision, image, voice, sound, and context-aware IoT applications as targets. It is a development and ecosystem collaboration; it does not by itself establish that every named application is a finished product or generally available feature.
Can Synaptics run AI locally without the cloud?
Yes, Synaptics’ stated purpose for edge AI is to run selected inference on-device, without requiring a cloud round trip for every decision. Whether a particular product can operate fully offline depends on the model, application, connectivity needs, and implementation. Local processing may improve responsiveness and reduce data movement, but the model’s capability is constrained by the device’s compute, memory, thermal, and power limits.

Model compression and quantization can help fit workloads within those limits. An August 2025 ENERZAi case study reported deploying a quantized OpenAI Whisper small model on the Astra SL1680. For that implementation, ENERZAi and Synaptics reported a 6.38% word error rate compared with 5.99% for the FP16 baseline, four times lower peak memory use than FP16, and twice the inference-latency reduction for a nine-second audio input. Those are results for the reported model and setup, not a general benchmark for all Astra workloads.
How edge AI compares with cloud-only processing
| Consideration | On-device edge AI | Cloud-dependent AI |
|---|---|---|
| Latency and offline use | Can avoid a network round trip and may continue operating without a connection for local tasks. | Depends on connectivity and the time needed to send data and receive a result. |
| Power and thermal budget | Must fit within the device’s available compute, memory, power, and thermal limits. | Moves the main model computation to remote infrastructure, though the device still needs power and connectivity to transmit data. |
| Privacy and data movement | Can keep more sensor data on the device, reducing what must be transmitted. | Requires sending relevant inputs to a remote service for cloud inference. |
| Model capability | Bound by the device’s resources; compression and quantization can reduce requirements, sometimes with accuracy trade-offs. | Can use remote compute resources, subject to the service and network available. |
| Connectivity and sensing | Synaptics’ stated approach brings processing together with wireless connectivity and sensing capabilities. | Typically relies on a network connection to the service performing inference. |
| Developer tools and evaluation hardware | Astra is positioned with open-source tools; Synaptics’ official navigation lists an Astra Machina Kit. | Tooling and evaluation hardware depend on the cloud provider and target device. |
What development hardware is available?
