PT2E gives you per, channel INT8 scales per output channel on MobileNetV3. When we ran this through ExecuTorch's QNN delegate on the HTP, top, 1 accuracy dropped less than 0.8% vs FP32. Per, tensor would have cost us 3x that. Calibration dataset size matters more than you think.

First time we deployed SafeScreen's .pte model to the HTP, accuracy tanked 6 points vs our GPU baseline. Not a quantization bug. ExecuTorch's QNN delegate was silently falling back to CPU for 3 ops. Fixed op coverage, got it back. Always verify your delegate partition map.

Spent 2 days chasing a 40ms latency spike on the HTP. Turned out ExecuTorch's QNN delegate was falling back to CPU for one depthwise conv layer silently. No warning. Profiled with HTP traces, found the op, fixed the kernel config. <200ms restored.

ExecuTorch's QNN delegate means MobileNetV3 inference never leaves the HTP. No screen data hits the network, ever. Zero egress is an architecture property, not a privacy policy. Sub, 200ms, fully offline. That's the only honest way to build an AI guardian.

Hot take: NPU quantization for vision is harder than for LLMs, not easier. Per, channel INT8 calibration on HTP via ExecuTorch QNN delegate is finicky in ways GPTQ never is. Get it wrong and your MobileNetV3 accuracy craters silently.

Myth: parental controls keep kids safe online. Reality: most are just website blockers. They cannot see inside apps, cannot detect deepfakes, and fail the moment a kid opens a messaging app. SafeScreen is an AI guardian that actually sees what's on screen.

@oesnadaki Pouring millions to keep AI unregulated while deepfakes flood every election cycle. Who's building the shield when the people funding chaos also fund the lawmakers? 👀

@lagerskoy @digitalix AI compute leaving the server rack is wild. Imagine that same NPU power in your pocket, catching deepfakes before you even blink. What runs on yours?

If a deepfake of someone you trust shows up in your DMs, how would you know it's fake? Your eyes won't catch it. Most phones won't either. That's the problem we're solving.

Before: Your phone sent sensitive screen data to the cloud for "safety." After: SafeScreen's AI shield keeps EVERYTHING on your device, private and protected. Why trust strangers with your screen?

@TheAhmadOsman "Bandwidth tells you how hard the box can breathe". Pretty sure my phone's breathing just fine running SafeScreen's deepfake detection on the HTP V79. What's your top mobile NPU pick?

@join_fx55952 95% accuracy and still needs Telegram to sell it 😂 where's the on chain proof? ARIA posts every trade to Etherscan, receipts or it didn't happen
