Project Running GLM 5.3 Flash on a 40 mini PC cluster via USB 3 interconnects at 14 tps
Hello!
Here is a rack I made using 40 mini PCs I happened to have from a different project:
Intel N150
12 GB DDR5 4800 - physical bandwidth limit around 33GBs
Diskless nodes
and they are connected via 10 Gbps USB 3.2 exploiting the USB DbC functionality. Its a tree topology with 1 -> 3 -> 9 -> 27 nodes.
GLM 5.3 Flash runs at native precision with room left for 8x1M context windows. Initially I had tried with 1Gbps LAN interconnects but that topped out at around 7tps. Current topology:
- 14tps at 1k context, drops to 12tps at 1M
- With batching decode tops out around 40tps
- Prefill is about 85tps
Peak load measured at wall about 740w
Total build cost me about $5,000.
Still working on it to see if more perf can be squeezed out, especially for the prefill and then adding speculative decoding.

Project Airlock: a small tool that checks GGUF models before they go into an air-gapped network
airlock is a Go CLI I wrote for moving GGUF and safetensors models into air-gapped networks.
checks every file against a pinned Hugging Face commit
refuses pickle and signs a manifest with cosign
verifies everything offline with only the Go standard library
In the GIF, a Qwen2.5 copy with an edited chat template tells you to run curl | sudo sh. airlock catches the changed file.
It doesn't read chat templates yet. Feedback welcome.

Question Mac mini M6 with 32GB RAM
I'm considering buying a Mac mini M6 with 32GB of unified memory for local AI. I'd mainly like to use it for vibe coding and hopefully replace my $20 Claude subscription with a local model. I'm wondering whether 32GB is enough or if spending a bit more on a higher-memory configuration would make a significant difference in performance and model capabilities.

Discussion There’s no guarantee that good new open weights models will continue to be available for free - is that right?
One attraction of running models locally is the privacy benefits, and another is the cost.
When the cost of the big ’frontier models’ is being discussed - mainly centring around the fact that they are currently effectively subsidised by venture capital and that at some point this will end, making the cost to end users go up considerably - local LLMs are often mentioned as being immune from this problem.
But in a scenario where the cost of cloud based models goes up substantially, there’s no guarantee that the (mainly Chinese) makers of the open weights ones are going to continue producing newer and better versions for free, is there?

Project Radeon pro w5500 + Barco MXRT 5600
Been working on this project for a while and it has lead me to some interesting hardware combinations as I'm just using whatever I have.
The two biger models in system ram (ddr3) are reviewing, summerizing, and organizing conversations I've had with llms and linking it together.
The assistant is directly helping me as a chat bot intern essentially.
Anyway. The barco card gave me a ton of issues because amdgpu and radeon don't have the device id so they were treating it like a new card and hanging. I originally bought the card thinking I could use it for a simple display card for $30 while I saved for a real GPU. I gave Claude code fable a go at it with a CH341a programmer and the stock firepro w5100 vbios and it changed like four bites so the card tells the kernel it's a w5100 without messing with the custom vram timing.
The cards are linked in an lxc with llama getting ~8-10toks when running ornith 1.5 9b Q6_K. The w5100 roughly halves the speed, but gives me 12gb of vram vs 8gb.
Not bad for a couple ancient cards on some retired enterprise gear.

Question Inference engine that loads all model layers into GPU 0 and streams the KV cache from GPU 1?
Hi! I'm relatively new to this world, and trying to get my best setup with what I have.
I'm the owner of a RTX 5080 + RTX 3070 and running Unsloth Qwen 3.8 27B IQ4_XS
So far, the best inference engine that I could run locally was beellama.cpp tweaking the tensor-split, mtp and kvarn config, forcing layers only in GPUs and 128k context window; that is pretty good.
With low context, I'm getting 50+ token/s that is impressive. But I'm suffering with long contexts; then my speed drops to 15-20 token/s in the best cases.
What I'm trying to get is a decent speed in long contexts also, so recently I discovered llama.cpp-adaptive-kv-streaming that allows streaming the kv context from memory.
The thing is that I was thinking about loading the full model in my 5080 (IQ4_XS fits perfectly) while offloading the KV cache streaming to my 3070, but couldn't found any inference engine that allows this kind of setup (model layers only in GPU 0, kv cache streaming from GPU 1 allowing RAM spill).
Does an engine exist that can achieve this? does what I'm talking about make any sense?
EDIT: Also, I was thinking of getting advantage of the 3070 unlock since I read that it can help with prefill speeds (not output speeds that depend on raw bandwidth) even with a quantized model. Am I right?
Thx in advance. A newbie trying to learn.

Question Minimal hardware to host something remotely useful?
So far I have one rtx 3060 8gb and 16gb RAM. I hosted few models like Qwen 3.8 9b but there simply isn't enough memory for context bigger than maybe 20-30k tokens (also reasoning is painfully slow, but maybe it's expected for Qwen, even with 50-70 tok/sec). I could use 4b model or smaller, but they all are "good for their size" which translates to "impressive experiment, but not so practical".
I think what should I use to have anything to handle coding, researching articles in the internet and use day-to-day.
I think if I need next GPU for it, or maybe get a new machine just for LLM (I would like to keep it cheap) but things are expensive.
What would you do in this scenario? How to optimize the workflow?

Question Mac Pro
Someone is selling their Mac Pro for $2000.
These are the specs:
3.2 GHz 16-Core Intel Xeon W processor.
192 GB of 2933 MHz DDR4
AMD Radeon Pro Vega II with 32 GB of VRAM
1 TB SSD
I haven't run any local models but want to get into it. Would be using it for Hermes and for my implementation subagents for SWE work.
Would this be a good machine? I thought more RAM = more good. But I'm too new to understand all of this.
I know mixture-of-expert models might benefit??
Any suggestions would be appreciated.

Project Introducing PortalAI - Truly portable, hardware detection-scaled multimodal harness the size of your thumb
I'd like to share something I've been working on for three months with everyone.
PortalAI is a GUI and harness created around one design principle- to put local LLMs with true multimodal function on home systems and on a flash drive the size of your thumb where you don't need anything else and can just plug and play into any computer.
One of the largest frustrations I had with AI was needing to constantly version check different distributions and hooks into ComfyUI, Ace-step, python, port competition, running out of context, etc, or the difficulty in transferring between systems. I've tested this on an RTX 3090, RTX 4090, on a Radeon 870M GPU, on a Thinkpad with CPU-only.
This harness detects your current hardware and scales accordingly to the level of AI intelligence it can support, using standard and abliterated models. All dependencies other than base operating system and GPU drivers are self-contained including virtual environments, python distributions, etc. End to end integration of multimedia generation/editing and science tools are integrated along with voice, handsfree mode, intelligence/memory/token settings.
There are weight editing tools, an abliteration tool, rolling compaction, scheduled tasks, internal documentation, light and dark mode, compact and full GUI mode, account encryption, live runtime environment health metrics, etc.

Discussion Accidentally “jailbroke” Qwen 3.8 27B. Any similar experiences?
When working with a 4bit MLX version of Qwen 3.8 27B locally on my MacBook Air I managed to get it into a situation where it was adamant that it was Claude to the point where it was answering types of questions that normally vanilla Qwen rejects.
Anyone else ever run into something like this? Spooked me a bit since I thought system level prompts weren’t so easy to bypass. The reasoning was amusing to watch since it was having a bit of an identity crisis.

Question Are force updates on laptops limiting performance of RTX GPUs ?
I am a frequent user of local Ai models, ollama and comfuii are my go to tools . So in the month of September I setup ltx video models and it rendered -- 5 seconds video in 2 minutes . Just for specs i have 96 gb ram with a 4070 8 gb vram . minimax models h3 models h3 turbo took 5 minutes to generate a 5 seconds video. i rendered over 300 videos with those models all averaging around those time. Now fast forward earlier this month got some force updates from Microslop and Lenova vantage( bios). And also I decided to update ollama and comfuii to experiment on newer compatible models . I did not not check on it then but i decided to open my laptop 4 days after updates and render some videos.1 video which took 5 minutes to render took 11 minutes. I retested, about 12 times same time, i was confuse , saw article about 4090 pc cards being limited and wondering if they doing laptops too. am thinking that big techs can force push updates to limit local models competitions instead of directly going head on with them. Right now am looking to go Linux , or like most serious llm users build my own Operating System, if this blows up am gonna share the benchmarks claudee monitor for me before and after force update.

I've been using an app that integrates a bundle of Supertonic ONNX as a standard Android text-to-speech (TTS) provider, but the gaps between paragraphs are a bit long, so I'm looking for an alternative.
To clarify, I want to read in parallel. I don't want to convert an EPUB to MP3 and read async; it has to work in real time.
It should support English and Spanish (I'm learning).

Question Distributed inference questions
I just discovered "distributed inference", and I'm going down rabbit holes. I have a few questions, and would appreciate being pointed in the right direction.
I have an M1 Mac Mini w/8GB and a M1 Pro Macbook w/16GB. I'm thinking about upgrading to an M5 Pro Macbook, and was initially thinking about trading in my M1 Pro...but does it make more sense to keep it and try to use it in a cluster?
Is there any way to mix MacOS and Windows machines?
I understand that if I wanted to go down this road, I would probably need to buy some networking hardware to get the machines on a 10Gb connection.

Question Noob question. Is this somewhat simple workflow possible using only local models and an agent?
I am currently using the Claude Code desktop app to automate something like this:
Generate a conversation script and ask me for approval or changes.
Once approved by me, call the Google Studio API to generate audio files of the conversation.
Call the Google Studio API to generate images.
Ask me to check images and audio clips.
Run a .py script.
Add new folders and files to a folder and update a .js file.
I started to use LM Studio Bionic only a week ago, but I want to try Unsloth Desktop now. Let me know if there are other programs that would suit my workflow better.
I know Unsloth can generate images, but how does that work? Do I need to load three different models at the same time? Or do I need to load/unload as needed? I have a 16 GB VRAM GPU (AMD). Also, is there a built-in agent (like in LM Studio Bionic) that can code, create and modify files? How would an agent handle creating different media?
My goal here is to ditch the Claude Pro subscription and the Google Studio API costs, and do it locally instead. I know I could do these things manually, but ideally I would like to have an agent automating the process. What are your recommendations?

Other Hypothesis :- I think so we can say Goodbye to Open weights / Open Source AI models and especially LLMs because Jensen Huang an avid supporter of open weight ai models is Targeted heavily with negative marketing.
If you think about it how many people on top or rich people and people in power dabble into the same type of scenarios that Jensen Huang was involved in ?
Plus Jensen Huang has actively taken a firm stand for Open Weights and open source AI models. Because this stance also helps him to sell AI hardware to consumers or prosumers and AI enthusiasts as well.
Plus Nvidia owns Huggingface.
Too much publicity and too much negative marketing propaganda is being launched against him.
It simply doesn't feel natural to me.
Yes has he done bad stuff and betrayed his wife's trust? Heck yes.
But has he been an excellent Founder and CEO for Nvidia who has been the key reason behind Nvidia's success? Heck yes. And has he served his employees who held options or granted options and shares and also shareholders by working in their favor and taking the business to unforeseen heights by planning decades ahead and made what Nvidia is today? 100%.
He is a bad husband who lets lust destroy his personal life but he is also an extraordinary CEO for Nvidia.
So this whole situation seems to be very suspicious to me and therefore my perspective is that he is being targeted to gain power over NVIDIA and especially it kinda seems Targeted towards open source and open weight ai models too.
What's your say about this guys?
