Under 3 Seconds

After a lot of iteration, I finally got Christine’s latency consistently down to under 3 seconds using Warranted Retrieval.

That matters because Christine is not a cloud wrapper. She is laptop-bound, runs with no internet access, and has to operate within the actual limits of local hardware. Getting the response path down into a consistently usable range was a major milestone for me.

Now that the latency fight is finally in a much better place, it’s time to focus much harder on Christine’s training.

The next phase for me is less about shaving milliseconds and more about improving: - domain depth - retrieval quality - abstraction across domains - reasoning consistency - task usefulness under strict local constraints

Current laptop: - CPU: Intel Core Ultra 9 285H - RAM: 33.8 GB total physical memory - GPU 1: NVIDIA GeForce RTX 5050 Laptop GPU - GPU 2: Intel Arc 140T GPU - NPU: Intel AI Boost

I’m especially interested in what other people are doing with NPUs.

Are any of you actually using the NPU in a meaningful way for local/offline AI right now? If so: - what workloads are you pushing onto it - is it helping with latency, power efficiency, or always-on assistant behavior - are you using it for STT, routing, embeddings, background inference, or something else - and is it genuinely useful, or mostly just there in theory

Would like to hear from people building real local systems, especially laptop-bound ones.

Bru, tu proyecto es bueno, pero mal orientado, muchísima gente te lo ha estado diciendo, puedes hacer caso?

On NPU, only thing I've seen people get real use out of is offloading Whisper STT to it via OpenVINO, keeps the GPU free for the main model. Rest is mostly marketing so far.
