MacBook M5 Pro and Qwen3.5 = Local AI Security System (https://www.sharpai.org)

I have always envisioned a ai server being part of a family's major purchases e.g. when they buy a house, appliance, etc. they also buy a 'ai system'.

Machine hardware evolution is slowing down, pretty soon you can buy one big ass server that will last potentially decades as it would be purpose built for ai.

Things like 'context based home security' yeah thats just, automatic, free, part of the ai system.

Everyone will talk to the ai through their phones and it'll be connected to the house, it'll have lineage info of the family may be passed down through generations etc, and it'll all be 100% owned, offline, for the family; a forever assistant just there.

This is a very flashy page that's glossing over some pretty boring things.

- This is a benchmark for "home security" workflows. I.e., extremely simple tasks that even open weight models from a year ago could handle.

- They're only comparing recent Qwen models to SOTA. Recent Qwen models are actually significantly slower than older Qwen models, and other open weight model families.

- Specific tasks do better with specific models. Are you doing VL? There's lots of tiny VL models now that will be faster and more accurate than small Qwen models. Are you doing multiple languages? Qwen supports many languages but none of them well. Need deep knowledge? Any really big model today will do, or you can use RAG. Need reasoning? Qwen (and some others) love to reason, often too much. They mention Qwen taking 435ms to first token, which is slow compared to some other models.

Yes, Qwen 3.5 is very capable. But there will never be one model that does everything the best. You get better results by picking specific models for specific tasks, designing good prompts, and using a good harness.

And you definitely do not need an M5 mac for all of this. Even a capable PC laptop from 2 years ago can do all this. Everyone's really excited for the latest toys, and that's fine, but please don't let people trick you into thinking you need the latest toys. Even a smartphone can do a lot of these tasks with local AI.

The M5 Pro just dropped, so here's a real AI workload instead of another Geekbench score. We run Qwen3.5 as the brain of a fully local home security system and benchmarked it against OpenAI cloud models on a custom 96-test suite. The Qwen3.5-9B scores 93.8% — within 4 points of GPT-5.4 — while running entirely on the M5 Pro at 25 tok/s, 765ms TTFT, using only 13.8 GB of unified memory. The 35B MoE variant hits 42 tok/s with a 435ms TTFT — faster first-token than any OpenAI cloud endpoint we tested. Zero API costs, full data privacy, all local. Full results: https://www.sharpai.org/benchmark/

Currently the barrier to entry for local models is about $2500. Funny thing is $2500 is about the amount my parents paid for a 166 MHZ machine in 1995.

I'm not very convinced by these prompt injection tests:

This is fantastic, but IMO it misses the most important part of a home security system from a business PoV - the ability to issue an alarm certificate. These are required for insurance discounts, as well as for making certain claims in the event of loss.

This is the classic issue in tech right now - it's becoming easier to build the systems, but the compliance/legal hurdles are still real, slow, and human. Even if the monitoring is best in class (which I'd argue it likely is - this is a fantastic application of AI), if the compliance isn't there it wont be a real product.

Can someone share how this stacks up to a Frigate? What I am struggling with this is how it sits in the security stack. Is it recording things of interest with motion or is it only a layer on top of the existing nvr

Just remember folks, the S in AI stands for Security.

Local AI is great for privacy-sensitive tasks, but the real power comes when you combine local inference with structured external data via MCP servers.

For example, your local Qwen model can call an MCP server that queries 9 public APIs (GitHub, HN, arXiv, npm, etc.) and returns structured JSON. The model does the reasoning locally, but gets real-time data from the web — best of both worlds.

Perhaps in the future, tokens will be sold at the price and in the manner of data traffic, becoming everyday consumables.

I would think a quantized 27b should be doable in mac world too?

This seems like an inevitable idea: a security system with full context. So you don't get alerts about your friend's car plates or your kid coming home late.

The software seems pretty interesting. Is any integration with Home Assistant planned?

carlgreene about 17 hours ago |

Wow this looks awesome! Will it work with Unifi Protect? I'm not seeing anything in the docs

I can’t even tell what this is trying to be.

How is Qwen3.5 with 9B anywhere close to GPT-5.4 with xxxB?

this reads as a very low quality and probably fully llm written post.

the analysis is very suspicious: “gpt 5 mini had api failures due to wrong temp setting”? wtf?

whatever you used to slop your benchmark didt even take the time to set the temp to 1 (which the docs say is required)

I'd like to recreate this benchmark using Qwopus on my M5 Max. I am curious if the theoretically improved reasoning capabilities from distillation improve its scoring. Adding this one to my to-do list for some point in the next few weeks.

llm_nerd about 17 hours ago |

Neat, but why would you want a clumsy LLM to know what happened with your security system? Things happened or they didn't, and that's what dashboards are for.

Seems like trying to make a need from the tools. My security system front page shows me every event that happened at my house, and I don't have to interrogate it on every happenstance, and I don't see what the value of that is.

Why would you run this on your M5 instead of a dedicated machine for it? A Jetson Orin would be faster at prefill and decode, as well as cheaper for home installation.

The Qwen 3.5 models are currently the best open-source models, but they are far behind proprietary models in speed and accuracy. I'd say they're about 60% on par with OpenAI and Anthropic models.

Why is there so much interest in local AI systems, am I missing something? Cloud providers have scale and expertise that would allow for much bigger throughput at lower costs. The small latency gains will be nice, but ChatGPT and Claude already come through blazingly fast via their API.
