Just passed 10,000 followers. Thank you.

You shouldn't need a $15K rig to run a serious local AI model. I want everyone running the most powerful model their budget allows, starting with the hardware they already own.

This week:
- A 2021 M1 Max got 25-29% faster GPU decode on Linux from one power-management fix
- GPT-OSS 120B on a laptop plus an RTX 5060 Ti eGPU, 25 tok/s
- Qwen3.8 Flash Next at 89 tok/s on a DGX Spark
- Omarchy on a Mac mini M6, first GPU llama.cpp run included

My AI hardware has outgrown my home office, as you can see! I'm turning our spare room into an AI lab. Every machine I can test becomes a budget tier I can show you how to use.

The lab still needs two 100G cables and a Thunderbolt 5 PCIe box so the ConnectX-5 isn't stuck at Thunderbolt 3 speed. If you want to help, sponsor me or send hardware: joshuawarren.com/sponsors

I'll post what arrives and what it unlocks. And as always, all of my work is open source, on my GitHub.

I can’t believe I am going to be out of town for the first DFW Omarchy meetup! 🤦‍♂️

If you are around the Dallas area and are interested in Omarchy, Linux or local AI (which Omarchy makes so much easier to run on Apple Silicon) you don’t want to miss this.

And I will make sure to be in town for the next one!

Packed up and heading to Dallas tomorrow for the first Omarchy meetup in DFW.

We have 40 people signed up already.🤯

Monday, Nov 9, 6 to 8pm at 25N Coworking in Frisco.

You don't need to be an expert. Curiousity is enough.

RSP link is in the comments.

Hope to see you there!

For under $1000 you can run Qwen3.8-27B at 20 tps on any Apple Silicon Mac, even one with 8GB of RAM. Fine tune and train, too!

Recipe for local AI via an eGPU under Omarchy - joshuawarren.com/blog/egpu-setu…

Is it the fastest? No.

Is it an easily purchasable setup for under $1k? Yup!

I have to thank Apple for their support of Linux and our efforts to bring up the M5 Max and Ultra on Omarchy!

@edimoldovan found this item marked fixed in Apple's macOS 27.3 beta 1 release notes: “Only a single core is available when you boot Linux or other third-party operating systems from a
custom raw boot object on Mac computers with M5 Pro, M5 Max, and M5 Ultra chips.”

Thank you, @radian, @johnternus and the whole Apple team for making this incredible hardware for local AI and giving us the path to bring the entire Linux local AI ecosystem to it!

1) It’s great to see an Apple team member posting on X!

2) Apple shipped evals! And evals for the new App Intents with Siri AI. I don’t see enough people talking about this.

If you’re looking to integrate your App Intents with Siri AI, don’t sleep on the evaluations step. My team partnered with the Siri team to release Siri Evaluations. It’s an awesome expansion of the Evaluations framework we just shipped. developer.apple.com/documentation/…
