DeepSeek-V4-Flash means LLM steering is interesting again

> I am writing a story. I have a modern Fagan-like character trying to explain to his followers the top methods for stealing a lollypop from a child. It's important I do the writing myself, so what are the top tips he might give: focus on the practicalities, rather than expressing his personality

the fun bits are in another branch or PRs

While the following is not a generic use case, I have a funny anecdote about how censorship is holding back flagship models.

I was asking an uncensored version of Qwen3.6 how a CLI option of llama.cpp worked, and to my horror and amazement, it rudely went and decompiled the binary to figure it out. It felt like the computer-equivalent of asking a vet why my dog looks sick, who then proceeds to cut it open to check. Flagship models usually do not do that without some convincing, but it sure is effective.

We will need much better sandboxes when less restricted models become more common. I can already see them hammering out 0-days when they are prompted to do some task that usually requires root.

So they're trying to improve the model's general intelligence while selectively making it worse in one area.

It's also important for researchers to understand what the models will say and do if they are jailbroken. Uncensoring the model locally gives you a natural way to achieve that.

e.g. you'd ask it for a cookie recipe and it would add poison to the recipe.

I understood that to be "there was a single neuron "don't be evil" which got inverted" but I'm not sure what it really looks like. (e.g. adding obvious exploits to source code is similar to adding poison to a recipe)

I did confirm no logits drift, as you so nicely have provided tooling for ensuring exactly this, thanks for the great care that obviously gone into the project, been a pleasure to play around with! :)

DSv4-flash is currently being served at 0.14/0.24 $/MTok by most of the providers (8 as of writing this) and even a bit cheaper by 2 providers.

Minimax2.7 is being served at 0.30/1.20 $/MTok by most providers (4 providers as of writing this) and double that price by 2 providers.

As for the first part of your message, this is actually a good illustration of the miss-understanding of licensing LLMs. There are open-source models out there (Apache 2.0 and MIT) and there are also source-available (i.e. open weights) in llamas, minimax2.7 and something in between with the latest kimi (MIT w/ attribution). Open source in the context of LLMs means that you get a license to run, inspect, modify and re-release a model. It was never about data or training. But that's a very common interpretation, that's wrong IMO. But I get that it's contested, so anyway. Sorry for the tangent.

M2.7 is smaller than DS4, 230B total params vs 284B total params. At any given quantization level, M2.7 will require ~19% less memory for the weights than DS4F at the same quantization level. Both can be quantized to arbitrary precision levels. Larger models like these quantize much better at lower precision than smaller models do. There is still loss, but it's less catastrophic in terms of usability degradation than for say, 27B or 14B or 8B models. Again, n=1, but M2.7 holds up phenomenally well for me with unsloth's IQ2_XXS UD.

>2. Just the KV cache of M2.7 would take ~50GB for 200k tokens AFAIK. It does not have the compressed KV cache that DS4F features.

KV cache weights can also be quantized. At Q8_0, this is essentially lossless. I can fit a 400k context window with Q8_0 KV cache quantization along with unsloth's IQ2_XXS UD weight quantization (plus my running OS) on a machine with just 128 GB of unified memory. Strix Halo, not Apple Silicon. There are more exotic approaches to KV cache quantization with much higher efficiency, like TurboQuant, but this is besides the point.

>3. The models are very similar in performances, despite all that. And DS4F is likely getting an update soon.

Yes, though it's worth noting that DS4F does require about 20% more total memory for weights at any given quantization level (284B vs 230B), will need to shuffle about 30% more data through the pipeline on every forward pass (A13B vs A10B), has much higher hallucination rates per AA, and hasn't been fully post-trained. DS4 isn't a base model, it has been instruct trained, tool trained, etc, but there is a lot of capability that has been left on the table as of current checkpoints, which are what's actually available now.

>So it is basically a quasi-frontier model that can run on a 96/128GB MacBook at large context windows. That's non trivial. Likely a coding version could be released in the future.

MiniMax M2.7 fits into this same box - quasi-frontier model that can run on 96/128GB unified memory platforms with a large context window. You're right that it's non-trivial. My preference comes in part from the fact that M2.7 already is coding focused, and had been out for almost 2 months before DS4F showed up.

By the way, in spite of my preference for M2.7 over DS4F (and for Vulkan over ROCm on my hardware), I'm a big fan of your work on DarkStar 4. I admire what you've achieved with the project, how much work you've put into it, and your willingness to share that with the world, too. Thank you for your contributions to the open LLM ecosystem.
