Head of Hardware at JetBrains. Any sufficiently advanced technology is indistinguishable from magic.

A colleague at JetBrains built a cool model based on Qwen 3.6 and 3.8 27B Essentially, he combined the two models and ended up with a model that performs better than 3.6 and is significantly faster than 3.8 when run locally. I ran this model all last week, and it performs very well in real-world scenarios. The model is available for free on HuggingFace huggingface.co/collections/J…

Junie has a new home on X: @junie_ai 👋 Follow for new features and announcements. First up: a smarter Junie Local, a new blended model, and experimental Windows support. The team has the details below 👇
We mixed Qwen 3.8 and 3.6. Literally. A 50/50 weight merge. One 27B model. 71% fewer output tokens than 3.8 in our internal coding eval. Junie Local has an update. Windows devs, you're invited too 🤝

There's a lot of work behind this. And the results are really great, especially for running it on hardware that isn't the fastest

JetBrains takes its first step toward Local AI. MacBook M5 users can set up Junie Local in one click and get a solid agentic experience. Unlimited & Fully local. Folks also had some fun presenting it on a plane :) Check it out & stay tuned for more: junie.jetbrains.com/local
Junie can now run entirely on your machine, and it’s completely free to use. One command: /local. We picked and optimized the whole stack around the model: agent harness, model parameters, and inference engine. No tokens, no quota, no code ever leaving your machine.

Set up the entire environment to launch and use a local model with a single command directly from the agent. The hardware options are currently very limited, but the list will expand in the coming weeks. We are testing various configurations right now

I think the biggest sign will be when they stop using model numbers. There will just be the model name, without a number. And the model will gain a certain kind of neuroplasticity and will keep improving day by day.
The day we develop really good models. There will be signs. Reliability increasing despite load going up and up. Sudden efficiency gains. Things getting faster. Resets. These kinds of things.

The new model from JetBrains. Works great on GPU
Mellum started with code completion. Mellum2 is built for more – handling both natural language and code. A 12B-parameter open-source LLM for routing, RAG, and sub-agents, optimized for ultra-low-latency inference. Now on @huggingface. Learn more: jb.gg/zpb9dp

The perfect use case for nvidia.com/en-us/products/rt…
Introducing the Lamark agent, The agent that actually trains the model for you. github.com/merocle/lamark-ag… It's designed with a focus on the “Local First” philosophy. I tested and developed it primarily for the Nvidia DGX Spark to leverage its strengths - specifically, its ability to fine-tune models. The agent learns every night through conversations with you. The focus on tools and the ability to call cloud AI models is implemented as a tool, too. The agent is completely open-source The next step will be to add support for more devices, and of course, the new @NVIDIAAI RTX Spark. It is based on Hermes and supports all of its features. Although personally, I've mostly used Telegram and the CLI I'm Inviting Contributors!

It’s finally up and running! And the result is pretty decent. Now I want to put this 1U platform... 😅

We're benchmarking every model, every quant, on every different hardware setup for every price point. All developers, companies, and people will have access to local, open source intelligence. Releasing soon.

Some real-world test results. 1. 2-node model – simple coding 2. Single-node model – similar task 3. Single-node model – simple chat (Hi, what can you do?) 4. 2-node model – simple chat As for the software @exolabs – it delivered the best results of everything I tested (but the choice for Mac OS isn’t great) A 4-node cluster is next. What’s really cool is that loading the model is significantly faster than on Spark (takes 15–20 seconds, rather than 5–10 minutes). But even with simple chats, the laptop starts making an obscene amount of noise.
