DwarfStar4 is a small LLM inference runtime that can run DeepSeek 4. The blog post implies that it currently requires 96GB of VRAM. For others who are lacking context :-)

That's the flash version not the full model and only at Q2-3~ so while impressive it's still quite different from the full model.

Not really. I'm building now another fast C compiler with DeepSeek 4 Flash, and rarely have to step outside to use Pro or Sonnet, gpt or kimi-2.6. Flash is very capable of almost everything.

Some of my colleagues believe that current frontier AIs are too heavily subsidized and it will come to an end. They think frontier coding AI's might get unavailable for one reason or another. But these kind of projects show that with 6000$ Macbook we are getting closer to a local frontier model. More importantly, it shows the genie will not go back into the bottle.

You can buy 128GB M5 MacBook Pros? Configured one just now, delivers in 2 weeks

Interesting there were news last week or so of apple removing Mac minis options.

They removed the baseline 8GB RAM/256GBstorage model. My bet is with increased RAM prices the markup on the lower end is not enough to still make a profit

Wink wink, nudge nudge.

I have a feeling most cybersec researchers would only be interested in negative values of "reduce" :D

In my (obviously anecdotal) testing, DeepseekV4 Pro was better than Sonnet at coding. However, it is much slower, but also many times cheaper, especially with the promotion right now.

Do they have a coding plan or you only pay per API call?

You pay per api call but you will be challenged to burn trough 20$ per month. 24/7 usage for single agent will probably cost you around 100$ per month. It is very efficient especially with modern harnesses.

Thanks. How is DwarfStar4 different from llama.cpp?

More information about DwarfStar 4 (DS4) in the readme: https://github.com/antirez/ds4

The code seems based on llama.cpp and GGML.

I don't fully understand why it is a standalone project. The readme discusses this: DwarfStar 4 is a small native inference engine specific for DeepSeek V4 Flash. It is intentionally narrow: ...

I think the only bigger difference in DeepSeek V4 vs other models is maybe the type of self-attention. And that leads to: KV cache is actually a first-class disk citizen.

But I still feel like those changes could have been implemented as part of some of the other local engines.

I also assume more models will come out, not just from DeepSeek but also from others, and they might share similar self-attention approaches, that would benefit from a similar KV cache implementation.

This project is a week old and already super popular. Guess people really were tired of lmstudio or tunning llama.cpp with settings.

llama.cpp (and consequently LM Studio) don't support DeepSeek V4. If you want to run V4, this is your only option right now unless you have hardware that can run vLLM.

When I ran DS4 Q2 the other day (without the new update Q2 imatrix) it was behaving quite poorly after a few agentic turns with opencode, it couldn't modify the files it was telling me the work was ready and didn't use any tool to update files
