I like trying new models but I wish we’d get something actually new. Like a new architecture or something. LLMs are just so sloppish. We can do better.

Talk is cheap. You have to actually beat transformers first. All alternate architectures that have sprung up are sidegrades at best.

We have something better than transformers, but not better enough to shift investement to it.

welcome to the sigmoid...

Why is that interesting?

Stepfun made a close to SOTA model with 3.5. They got overtaken quickly but have shown enough to be given attention when a new model releases.

It’s also an open model. Even if you only use Opus and Sol, these open models help push them and the frontier.

Seems like it was an under-noticed model back when it came out because there were so many new Qwen models coming out around the same time. I tried it some on my Strix Halo box, but it was right on the edge of fitting.

3.5 Flash was decent, but I was using it on OpenRouter. What model are you running on your Strix Halo nowadays?

Qwen-3.8-flash-next @Q4

Not sure why this is downvoted.

It is fully possible to run the 180B Owen model on strix halo using strata and even get reasonable speed out of it.

Indeed - Even with llama.cpp you can store n-grams to disk and use it. I m using unsloth's llama fork atm but a new llama release is out that may be better - hadn't had time to test it yet.

Yes, this on Halogen. I can get ~45tok/sec which is quite usable.

well, it's free for now , beyond that eh.

Back in their 3.5/3.7 era [1], they had a small+fast model, specifically eschewing knowledge, and instead focused on "general intelligence" like managing tool calls, orchestrating sub-agents, etc. Could be a very good substrate for running a personal assistant (time will tell what's the right approach); so I'm curious to try that out and see how they've come along since then.

Wonder if this was the space bunny alpha model

After some quick tests, it likely isn't. Additionally, Space Bunny Alpha had hints it was a Minimax-variant model.

Its been on ZenMux for at least 2 weeks so I doubt they are hiding

It doesn't look competitive along any dimension: https://artificialanalysis.ai/models/step-5#intelligence-com...

Better luck next time.

It's fast. The average speed is 115 tokens/sec according to OpenRouter. I haven't tested the model to see how it is in practice, but I'd certainly pay a little extra for faster inference.

Edit: Though the average latency of 1.5s isn't very low, so it might not be that fast in practice for agentic work. Also, I don't know how much thinking it does, as that's generally been the drawback to Chinese models.

Using Artificial Analysis

Model | Reasoning | Intelligence Index | Artificial Analysis million output tokens for the intelligence index -|-|-|- Step 5 | ? | 44 | 160 GLM 5.3 | Max | 45 | 210 MiMo V2.6 Pro | ? | 46 | 140 Kimi K3 | Max | 44 | 160 Qwen Max 0902 | ? | 45 | 190 DeepSeek 4.1 Flash | Max | 39 | 250 GLM 5.3-flash | Max | 42 | 180 GPT-6 Astra | Low | 46 | 10

It looks reasonable by open model standards. This doesn't capture the fact that DeepSeek and Step 5 have much higher token/s than the rest, other than MiMo Ultraspeed. MiMo V2.6 is either slow but cheap, or fast but expensive. Just based on these numbers, it looks good. Astra-low is one of the fastest and cheapest because it doesn't use many tokens, but I've never tried it. I liked DeepSeek and GLM when I used them.

Artificial Analysis has some very specific biases or perspectives on what they are measuring, so I wouldn't take their benchmarks as the final word on model quality.

Composite indices are only useful for model companies which want to build one horizontal capability for N use cases, or naive users who don't want to bother with the effort of carefully pairing models with use cases. If you're a power user looking to understand and make deliberate choices, then you want pointed evaluations -- not general composite indices. You wouldn't hire the same person to do your taxes and mow your lawn, so why is it any different with LLMs? Only if you come at the problem with the folklore around "AGI" do you start making composite benchmarks.

As I mentioned in a sibling comment...

> carefully pairing models with use cases

I've always wondered if there were niches that some models are better at. I use them for software, electrical and mechanical engineering plus other things. What are some notable subject-specific differences you found?

Come on... That chart shows Sonet 5.5 as better than Qwen3.8-Flash-Next. I have observed the opposite.

Re: the edit where the OP added an image: I'm more bemused than offended.

I'd just read it as social friction, just like I'd read your comment as that very same thing.

This is the consensus mechanism doing its job, essentially.

__

Though to be fair, the way I frame it assumes no connections between nodes and independent choices, when in reality, we have groups supporting each other.

So it's not necessarily the best mechanism, as social cohesion and other such dysfunctions might be steering away from the objectively correct solution through not necessarily rational biases.

Or rather not necessarily rational when viewed in just the specific context, but possibly rational when zooming out and considering whole-subsystem health.

Low-effort content is generally discouraged on Hacker News because it lowers the quality of the site. It's not a deep commentary on socioeconomics.

Like posting the exact same personal brand-building under each new model you mean?

As said, there is no right or wrong here. Well, technically there is and it is my opinion (obviously), but if we take a step back, it's exactly what I just described and you (unfortunately) discarded through bulldozing.

The """"thought leaders"""" will have to live with the fact that some people just don't think that their work is adding all that much value. It's a bit unpleasant for the ego of course, but that's kinda the trade when making money with fluff.

Pelican Police. Cry more.

I love the pelicans almost as much as the penguins. One day we shall see the max positive of minimaxir ;)

There was a better alternative, buried by dumb HN censorship:

paging Simon Wilson!

He’ll probably respond quicker if you get his name right

Well, according to Artificial Analysis (which I'll admit I've been using as a bit of a mental crutch to avoid comparing models myself, so YMMV), it's smarter and slightly cheaper than Gemini 3.8 Flash, which has been my benchline for "cheap and smart enough", I'll give it a try on OpenCode for the week but I'm not sure I'll be compelled enough to switch from Muse Spark 1.3.

Step models were IMO the first local model you can run on 128GB shared memory that worked well. Really excited to see how it compares to Qwen Flash Next.

Edit: bummer, didn’t know it’s 600B-A27B. No way to run that on 228GB.

Earlier this year, Step 3.5 Flash and then Step 3.7 Flash were easily my favourite local models. Step 5 is far too large to run on my DGX Spark-like, but I’m excited to try it out. It’s benchmarks look promising, and I’m hoping it’s a lot faster than GLM is

Totally. I think Step 3.5 was the first model that made me sit up and realise that LLMs weren’t a fad

It should be mandatory to put benchmark results on the beginning of the page describing new model release.

How am I supposed to know if it's even worth my time?

can I be frank? It's a pile of rust. Nowhere near Muse 1.3, weaker than Ling 3.1, probably just a bit over Nemotron 3.0 Ultra, and that's it. Totally underwhelming - broken prompt responses, garbled repo state, derailed trajectories, hallunies, you name it. Maybe good for some trivial stuff, but that's it. Terribly slow on top of that, quite pricey after the free trial ends, not suitable for local use, and not good enough for cloud. We already have stronger free models, we have faster models, smarter models, cheaper models... Also, benchmarks are obviously benchmaxxed. Once again - on high effort it feels basically just a notch above Nemo. Get a real task, launch it, and cry in terror.

AND I'm not even comparing it to the flagships - y'know we just got Muse Wonder literally hours ago?!

tl;dr underwhelming
