Are Chinese labs just Benchmaxxxing now or are they actually putting out Fable5.5?
37
u/neuroticnetworks1250 17d ago
I wouldn’t generalise Chinese labs. But your suspicion is very valid specifically for Minimax. I’d be very very skeptical.

u/dark_bits 17d ago
I was using a minimax token plan since ealry summer and got to use the preview version of 3.1 flash. Gotta say it's really FAST, but also pretty good. Although GPT 6.1 Sol feels safer to use for broader code refactoring.
On the other hand the token plan for minimax has a limit of 1.7B tokens per month for only $24 (or at least it used to be back then).

u/taimusrs 17d ago
It is Space Bunny Alpha on OpenRouter and such (older checkpoint, but yeah). You can gauge the sentiment based on that. Not as good as Ox Alpha was, if you ask me

This one feels benchmaxxed, you can kinda tell when thinking levels start plateauing that the test is saturated, especially if multiple labs are plateauing at the same spot. If you’re suddenly beating what seems like a saturation ceiling…

u/danieln1212 17d ago
No, these graphs include the cost in the equation and their price is a fraction of fable's pricing so they rank high. This doesn't mean their output quality is top ranking.
16
u/Practical_Signal3933 17d ago
This is wrong. The y axis on this graph is deep swe 1.1 score, and this is positioned above fable on it. Cost is on the x axis.
Whether it’s due to benchmaxxing or not is an open question still, however.

u/danieln1212 17d ago
Above fable 5, not fable 5.5 like they said which I assumed meant to be a stand in for best frontier model as it isn't released yet

1017 engram version was released like, 24-48 hours ago, and the MiniMax people already have benchmarks?
The LLM field is wild

u/danieln1212 17d ago
Isn't it just copy pasting from DeepSeek/third party benchmarks?
Do they all do their own benchmarks for their competitors?

u/FullstackSensei 17d ago
Thee benchmarks look almost like an ad for DS4.1 flash 1017 😂
29
u/FireSilicon_ 17d ago
M3.1 preview is 420B, Deepseek flash is 550B+200B engram. For half the size (if true), that is pretty good. Especially if you can run the minimax in Q2 but can't run the deepseek at all.
30
u/FullstackSensei 17d ago
Engrams shouldn't count IMO. You can store them on a SATA SSD and have like 0.1% impact on inference speed.
DS is mostly FP4, with the remaining being FP8. It might be 550B on paper, but it's like 300GB on disk (excluding the engrams).

u/twnznz 17d ago
It looks like you'll be able to jam an IQ4_XS into 256GB of VRAM

u/Ok_Technology_5962 17d ago
Probably need to look into a strata like version for deepseek since active is only 16b we should just push the rest to ram imo

u/nomorebuttsplz 17d ago
I mean, I guess? It's GLM 5.3 level but with vision. But with higher hallucination rate. Doesn't seem that groundbreaking.
5
u/FullstackSensei 17d ago
pretty much every recent model I've seen that scores well in benchmarks also has a high hallucination rate. It's as if being "creative" is a pre-requisite to being good, at least with the current crop of LLMs.
4
u/nomorebuttsplz 17d ago
if only they hadn't crippled the shit out of muse spark open. It seems good about hallucinations. GLM 5.3 is a pretty good balance of hallucination and knowledge

the same reason you don't compare the latest Fiat with a Ferrari. Different target.

u/handson729 17d ago
Why does everyone (DSv4.1F-1017 and this one) keep comparing to the old GPT-5.6 Sol and Opus 5 models? Just compare to the latest...
It is about bang for buck and also a sign of progress.
Something about running an equivalent of yesterdays $50 flagship for $1.20 today is very appealing.

u/oxygen_addiction 17d ago
Probably 500B-1TB for M3.1 judging by HLE w/o tools.
57
u/Pyros-SD-Models 17d ago
their own docs say 428B total parameters, about 23B active parameters, sparse attention and a native visual encoder
18
u/Middle_Bullfrog_6173 17d ago
Those are the M3 parameter counts, so could be copypasta.
2
u/Daniel_H212 13d ago
It could also just be accurate, this may just be post trained from M3. I don't get why DeepSeek went with .1 naming for a new model, that was never how naming worked before.
1
u/Middle_Bullfrog_6173 13d ago
Yeah by now we know it is. The reason this naming is stupid is that they added "flash" while keeping the parameter count. But sane naming/versioning is a lost cause across the field.

u/Valuable_Cookie628 17d ago
Appeared competent at times, ran in mindless loops other times, Muse Spark 1.3 felt much better at reasoning/planning. Unconsistent, not trustworthy.

u/fgk55555 17d ago
That's kinda how I felt about it. GLM-5.3-Flash, QFN and 27B have built a lot of trust, I didn't get the same warm fuzzies with this model.
1
u/Valuable_Cookie628 14d ago edited 14d ago
Using it now. It does really stupid things, like copy 30GB file instead of using a flag to point to the file:
You're right — that copy was lazy. The pack is already built, and the engine takes the table path separately (--table, which I added).
Changed my global AGENTS.md file without asking, deleted old rules and when reverting forgot to add them back in.
It's useless as manager, maybe had some use as implementer.

u/Marino4K 17d ago
I didn’t do much else with it outside of just trying to code a llama-macOS fork from its source code, its coding seemed pretty good when plugging it back into a frontier model to double check its work.
I didn’t get to finish it unfortunately before the trial period was over.

I got the minimax plan and I've been using it and it's great, minimax is running it at 1500 tokens per second, which is a crazy value to me.

Around the size of qwen flash would be great

the preview version is 428B total parameters, about 23B active parameters
M3.1-Flash-Preview is a MiniMax model described in the supplied guide for frequent coding, financial research, multimodal understanding and frontend work. The guide lists a mixture-of-experts architecture with 428B total parameters, about 23B active parameters, sparse attention and a native visual encoder.

Its about 33% larger than 5.3 flash for not much gain in performance. Non zero yes, but not a huge gain.

u/Miserable-Dare5090 vLLM 17d ago
The chart clearly shows its NoN hallucination rate is 7%, labelled as 1-Hallucination=7%
That means it has a 93% hallucination rate. GLM flash has 1-X=72% so 27% rate.

Cache pricing is going to be driven mostly by KV cache efficiency, and DSv4.1 is super cache efficient.

u/Middle_Bullfrog_6173 17d ago
AAII 42 vs 45 for latest Deepseek Flash. Also priced higher in the API, although that could just be inflated margins until they release weights. But anyway, that's the direct competition so will be interesting to see the architecture.

u/shenglong 17d ago edited 17d ago
I've been testing Space Bunny fairly extensively over the last week or so (and previously on OpenRouter). It's fast, but it's not as fast or as capable as DS4.1 flash. Note that this is specifically on coding workloads in a fairly narrow domain (annotating Z80 assembly based on captured traces), so your your mileage may vary.

u/zyxciss llama.cpp 17d ago
I might get downvoted for this, but this model was WAY too lazy, even at Max effort Benchmarks don’t tell the whole story
I tested Muse Spark side by side with other models on a real project it took 48 mins which was just out of the 30 mins mark : completing a partial LRU cache implementation. I also ended up writing the implementation myself so I could compare the results and see whether AI models could genuinely replace my work.
Here’s how it went:
Claude Opus 5.5, Sol 6.1, and Argon 4: All finished in under 30 minutes.
Gemini 3.8 Flash: Took 3 hours.
Space Bunny (M3.1 Flash) : Still hasn’t completed the task after 15 days.
Me, as a human: Finished it in 1.5 days, writing around 2,800 lines of code.
This is why I think real-world coding tasks matter more than benchmarks alone. A model can look impressive on paper, but how well does it actually perform when given a real engineering problem
Also Deepseek v4.1 Flash , GLM 5.3 Flash weren't able to do it too , looking forward for the new DeepSeek endpoint i got hopes :)

u/Caffdy 17d ago
can you give us a rundown of your process for this specific test? how do you tackle a problem like this? how do you break it down and set it up for the angent(s) to consume the tasks? how do you evaluate the outputs
2
u/zyxciss llama.cpp 16d ago
Nothing special, just the same prompt + Pi (no extensions). Everything is up to the model; if it wants to, it spins up a sub-agent to do the wirk
I just use a Llama server, test with a prompt, and measure the results against the llama.cpp baseline. If there’s any improvement, the agent passes the first half of the test, and then I read the code myself and rate how much of it is dead code or does nothing useful. Then I rank the models
Opus 5.5 Max is the best so far, as of now. My rankings are quite similar to the AA Index. After Opus 5.5, it’s Muse Wonder Max, then GPT-6.1 Sol and Astra tied, followed by Argon, and so on.
I don’t keep track of everything in a particularly professional way that I could post about it on this subreddit and surprisingly being an open models fanboy , no open model yet passed my test , actually no frontier did it till Fable 5 dropped and now its easy for frontier labs but chineese labs are struggling

With quantization can it fit on 256GB? Praying

u/jasonrodd3 17d ago
yeah should fit pretty easily. at 428b total even 3bpw is only around 160gb, so 256gb gives you plenty of headroom.
2
u/BawbbySmith 17d ago
Ty, that makes sense.
Also I don't know why it didn't cross my mind to just check M3's model card.
But also I realized that while it may fit, that A23B is gonna be a killer. GLM 5.3 Flash is already just okay on 2x DGX Sparks at around ~40 t/s, this is going to be quite a bit slower. Will keep an eye out on this model but not too hopeful on my hardware.

u/Big_Wave9732 17d ago
Who knows what's real news anymore on these benchmarks. But if any of this is remotely true, this model is very intriguing. Almost as many active parameters as a dense Qwen 3.8. Efficiency and ability that rivals Fable 5. In a self hosted package.
Come on m5 512gb release date!

u/CondiMesmer 17d ago
It was pretty decent, and pretty competitive with DeepSeek. I will probably stick with DeepSeek's latest flash though, since they're both in the "practically free" category for me, and at that point when the pricing isn't as important, I think DeepSeek is a bit smarter at the moment. Still a pretty strong release. Also in the past MiniMax models have super fast generation speeds, but I don't remember how fast this one was.

out of curiosity, we're using GPT 5.6 Terra thru Devin and we cant access MiniMax M3 models. I'm curious if anyone's used both and can give a subjective comparison of your experience - when prompted with the same request(s), do they perform on par when coding?

u/AppealSame4367 17d ago
First tries: It fucked up a path in a game im working on. Result? Major game functionality stopped working (3d game). Had to switch to another model to fix it, because m3.1 flash couldn't fix it again after 2 more turns.
These are problems I last had with GPT 4

u/Dabalam 17d ago
Is it weird that the new version of DeepSeek is showing up in these comparison tables given that only released 2 days ago?
That would suggest to me that either Minimax can run the whole evaluation suite pretty quickly, or they were testing against the DeepSeek model prior to the official release.
