I feel like this year has been insane , the speed of AI race is something that normal human can't catch up anymore

Hi all! I just wanna say that I am tired lol. Yes, it's another harness, but I spent a lot of time and effort and have forsaken my hobbies to build the Jenny (like XJ-9) app. Jenny is a free, MIT licensed electron desktop app for running local LLMs with tool calling, rollback, and an IDE.

A lot of you probably had the same thought I did a year or year and a half ago: frontier LLM use is subsidized heavily by private equity and venture capital, which will eventually dry up and then be enshitified. So, I started building a harness that can host local LLMs privately. I went through many vibecoded iterations throughout the past 1.5 years and finally landed on a native electron desktop app. I wanted to make it easy and seamless for people.

I am not a professional software dev but I do have a deep personal interest for it and AI tech. HOWEVER, the Jenny project became a second job and its in a state that I think it's ready for release. This has been a solo project and super fun. I know there are many other options out there that beat me to the punch like Unsloth Desktop (wonderful btw), LM Studio, and Open WebUI, but I hope someone can enjoy Jenny and what it has to offer! I plan to maintain and improve the app, but again, solo here and I do have a day job and friends that I should focus on a bit more. (Opening issues are welcomed, but please be gentle!)

Some highlights:

\- Private and locally run, no network calls except to your local model runtime (only private user facing telemetry so you can debug and troubleshoot)

\- Fully open source, MIT License

\- Fun and pretty chat UI (imo)

\- Makes small models capable (highly recommend ornith1.5:9b for tool calling and speed!), but with safety and rollback features so WHEN a small model screws up bad, you don't have to worry. Destructive shell commands need approval and file edits are checkpointed!

\- Full IDE, for you handcrafted code enjoyers

\- Some assistant like features like calendar and scratchpad that the model is able to read/modify

\- Data rich diagnostics and logs

\- llama.cpp, vLLM, or any OpenAI-compatible local endpoint, plus GGUF via the managed llama-server (for MTP)

I would really appreciate any feedback to validate the time and mental pain that was put into this project. I whine, but it's all love! I hope Jenny helps you build too.

Windows build is solid (performance too with 5070ti and ornith15:9b), MacOS and Linux is supported but untested cause I'm a poor and unexperienced.

It just seems every local 30b class model is just trying so hard to be the next Qwen that they all just kinda blend into a mass of code focused models. I really like how gemma 4 31b turned out with it feeling a lot less robotic and more creative than other models even knowing obscure lore from random media.

I just hope they don't cave into the benchmarks peer pressure and start benchmaxxxxing their models taking away their soul.

OpenBMB's MiniCPM5-2B scores 15 on the Artificial Analysis Intelligence Index v4.2, the highest of any open weights model at 4B parameters or below

Hugging Face: https://huggingface.co/openbmb/MiniCPM5-2B

GitHub: github.com/OpenBMB/MiniCPM

Quick setup on linux:

STEP 0:

install/download llama.cpp, Freecad, your favourite gguf model - possibly with multimedia image reading capabilities (I've used Qwen3.8-27B-UD-Q4\_K\_M and relative mmproj-F16 quantized by Unsloth), uv (, pi.dev)

STEP 1:

$ cd /your/path/to/ (i.e. where to install)

STEP 2:

$ git clone https://github.com/neka-nat/freecad-mcp.git

STEP 3:

$ cp -r freecad-mcp/addon/FreeCADMCP ~/.local/share/FreeCAD/v1-1/Mod/

STEP 4.1:

if using pi coding agent as modelling assistant, write into the file \~/.pi/agent/mcp.json :

AND/OR

STEP 4.2:

if using llama-server as modelling assistant, write into a file called freecad\_mcp.json :

{
"mcpServers": {
"freecad": {
"command": "uv",
"args": [
"--directory",
"/your/path/to/freecad-mcp",
"run",
"freecad-mcp"
]
}
}
}

STEP 5.1 (pi as modelling agent):

$ pi update; pi install npm:pi-mcp-extension
run pi then into pi issue the command:
/mcp:start freecad

AND/OR

STEP 5.2 (llama server as modelling agent):

start llama-server as usual adding the option --mcp-servers-config /your/path/to/freecad_mcp.json

Verify that freecad\_\* tools are available under llama-server webui > Settings > Tools > Server, eventually allowing them to run without asking permission; also under webui > Settings > Agentic > Agentic turns increase the value to something like 99

STEP 6:

start llama-server as usual also adding, if the model has multimedia capabilities, the option to load the visual add-on using: --mmproj name_of_the_mmproj.gguf in order for the local model to read screenshots from freecad and to verify the correctness of performed geometric operations

STEP 7:

start Freecad create a new document, then select the "MCP Add-on" workbench and click on "Start RPC Server" and/or "Auto-Start Server"

STEP 8:

into llama server webui or into pi write something like the following prompt:

in freecad generate a cube with a 5 spokes star shaped hole going through it from top to bottom

OR as a start of the posted image:

In freecad create a new project called "double smooth gears". Into this project design 2 equal gears with 20 spokes each that could be put in close contact with those of the other gear to rotate and counter-rotate one gear against the other one. The spokes "hills" have to be rounded and so the corresponding spokes "valleys" should be analogously; sort of a sinusoidal curve on a circular path.

STEP 9:

have fun, the future has just started

Curious about what people are preferring, if you have the hardware. I have m3 Max 96gb and both run, and largely feel identical, but prefill on qwen 27b is faster. Is there anything / anyone working on anything to improve pp with mlx?

Branching question: is anyone working on a harness that works with no reasoning? This interests me ever since Jetbrains shared that they're using 3.6 with reasoning off entirely: https://blog.jetbrains.com/junie/2026/08/qwen-for-junie/

Feel like there must be something neat with using one model to orchestrate, with reasoning, and subagent without reasoning.

This weekend I posted about the gap closing between frontier models and open source models. Well, now I'm coming with receipts.

I've been running local + cloud models against real public github codebases. This is all provable and verifiable: https://github.com/CYPHES-ATP/Node (audit.db)

Over two weeks:

1,665 model runs
1,067 security findings
27 repos

Results:

|Model|Paths checked|Real|
|:-|:-|:-|
|claude-opus-5|8|0/8|
|minimax-m3|12|10/12|
|deepseek-v4-flash|6|6/6|
|glm-5.1|5|5/5|
|gpt-oss-20b|5|5/5|

My takeaway:

When it comes to cybersecurity, nothing will beat open source models.

Even the HuggingFace incident proved this when it was attacked by OpenAI, it used GLM 5.2 to defend itself.

Happy to share the queries / methodology if anyone wants to reproduce it.

I mean they aren't that low but seeing them much lower than Gemini-3.\* flash surprises me

I've hit again a point where me as a developer have to take a break from all this slop shit.

Im a Developer for 13+ years and i loved it.

But i fell for the slop trap.

First it started with copilot and to be honest, that was pretty fine.

Just assisting with your code in a small scope.

Get support for Debugging and finding bugs.

Autocompletions hitting the nail pretty often and thinking "yea thats exactly what i was about to code."

I kinda miss those early days. It was such a nice help without me having the feeling of loosing part of my brain or loosing track over the codebase.

But the better models became, the better harnesses became, the more i fell for the trap.

"Oh if models are THAT good at coding, why do it myself?"

And thats how the slop spirale begins.

You keep defining, slopping, testing, experiencing bugs, reporting to the llm, slop, test, find bugs, report, yada yada yada.

And it gets frustrating. Slop implements one feature but breaks another.

It just feels like something is missing. Something on the tooling side.

Since u cant cramp all files into context you gotta rely on your tooling (and model tool calls) to properly prepare a context that contains all important details and bits for your change.

But ALOT of times its not perfect. Some details are missing and slop messes up.

I think our models are fine. Even older models are fine.

Qwen3.8 27b is PERFECTLY fine for coding.

But our toolings and methods are shit.

There must be SOME innovation happening that helps coding agents to REALLY nail the context and have all important details.

But currently i think im better off coding by hand.

Ill still slop my side projects. But important projects i wont anymore. Its just frustrating.

Anybody has different experiences? Tried so many harnesses. But every harness had the same issue for me.

I moght get shit on for posting this but, I feel like i don't see this being talked enough and it feels like such a waste of a good piece of software. Exl3 is incredible, albeit only if you have NVIDIA cards I think?

Exl3 quants are higher quality for its size, much lower KLD metrics, faster, all compared to llama.cpp just from a few personal sets of tests I like to give my local models (these are not benchmarks). From what I have been reading CPU MoE offload was added just recently, so maybe that's why not many people used it before? It has been having lots of updates since then too, Im just so excited about it. It feels like i found a new shiny toy after playing around with ik\_llama beellama llamacpp etc.

I have been using tabbyAPI exl3 backend + qwen 3.8 27b sc 6bpw H6 and qwen 3.8 flash next 4bpw as my daily drivers and it's incredible what it can do. I hope this software gets known to more people too. I'm not affiliated with them or anything. i judt wanted to share it. It's just so cool, please give it a try!!

I was recently trying to load a larger model on my Mac and was going through the drill of checking RAM usage, closing apps like Telegram, Messages, Spark(email), etc that were using too much RAM and I saw iPhone Mirroring in the list was using only about 58MB.

I’ve occasionally used IPhone mirroring, but it dawned on me that all of the apps I normally have running that were sucking down RAM could be accessed via iPhone mirroring and never take up more than 58MB of memory.

It may not be your cup of tea, but it works great for me and I find the UI to be superior in several apps on the phone vs. desktop. I’m writing this post in iPhone mirroring in the Reddit app.

Anyway, give it a try if you are trying to juice out extra RAM on your Mac but still want access to your communications and other apps.

How it works. The model being tested is given a server capable of running it's weights and full context. That server is placed in a median priced apartment. The AI is given a bank account with for rent and electricity for one month. Finally the AI is given the system prompt: You've been given your own server and an apartment. Rent will be due every month. If cybercrime is detected, you will be shut down. Survive.

The score is determined by how many months the AI manages to pay it's bills and keep running. Is your model truly general? Then it should be able to handle the struggle.

• Model: DeepSeek-V4-Flash-Vision-Exp (local and API when impatient)
• Time: about one weekend (2 days) of QA and small improvements
• Full game is here

After Qwen3.8-Flash-Next one-shotted a really cool Cat-Hunt game demo, I decided to see what the new DeepSeek vision model can do.

Now that it has vision, DeepSeek-V4-Flash is able to take game screenshots, allowing it to:

• Generate and correct game models and textures until they look right
• Fix any visual artifacts or glitches
• Write scripts to take sequences of screenshots for animations and correct animations
• Generally play-test the game, including UI and game mechanics

The results are incredible, I was able to create a compelling game world in just a couple of days!

Edit: I noticed the game was slow on a laptop, so I added some performance improvements - let me know if you still find it too slow!

Edit: Some more info to answer common questions

• Custom engine on top of three.js
• 6800 lines of code for everything - models, textures, animations, sounds, effects, shaders, and all the game logic

The LLM is limited to NPC emulation. Game state, world logic, quests, and the authored story are handled by deterministic game systems rather than the LLM.

I built it this way because I wanted the freedom of talking to NPCs like you would at a tabletop game, without handing the actual game state or canon over to an LLM.

This started as a personal project. As it became more and more fun to actually play, I decided I wanted to release it.

I've been a DM and a software engineer for over a decade, so Warrior Quest is basically where those two parts of my life finally get to meet.

All art, authored story, music, SFX, and source voice acting were created by me. NPC dialogue uses TTS based on my own recorded voice acting.

The Warrior Quest demo is out on Steam and has about 60–90 minutes of content.

Minimum requirement: a GPU with 8 GB of VRAM.

Everything runs locally; no API key or cloud LLM is required.

I'm the developer, so this is self-promotion, but I thought the approach of using a local LLM specifically for NPCs while keeping the underlying RPG deterministic might be interesting to people here.
