Very strong pricing, cheaper than Grok 4.5, particularly the cached reads. We'll have to wait to see if it's actually worth using (it's not on OpenRouter yet).
rpgbr•39m ago
That's what one does when its product and public perception is way behind competitors.
Tiberium•51m ago
The pricing is insane: $1.25/$4.5 for 1M tokens, and $0.15 for cached input!

https://dev.meta.ai/docs/getting-started/pricing-rate-limits

ignoramous•40m ago
Cheaper than Qwen 3.7 Max. Second indication, after Grok 4.5 ($2 in / $6 out), that the BigLabs are feeling the GLM 5.2 heat.
fallingbananna•29m ago
Meta isn’t right now on the radar for most folks picking models.

If they have a really good model, it makes sense to subsidise it, to gain users, before they align prices with competitors.

ycui7•22m ago
this is not subsidizing. this is way too expensive for a no-name model.
kilroy123•51m ago
I personally do not like Meta, but I'll say this. The more competition, the better for regular consumers. (Enterprise too)

- Chinese models

- Grok

- Meta

- Google

- OpenAI

- Anthropic

I think this is a win. I'm building like crazy to take advantage of all these subsidized tokens while I can.

alansaber•41m ago
Meta's local llama models used to be the face of open source AI. The scene has really changed.
cyanydeez•5m ago
they likely got the Peter Theil newsletter proclaiming open source models are the antichrist
cpt100•37m ago
Yeah, I think it is definitely great. Having said that, I am still debating in my mind whether the volume of software engineers needed in the AI era is going to increase or decrease because of all of these advancements.

On the one hand, because it is easy to build products, more and more people will build. And more and more products and features will be built. However, a lot of people who are non-technical will also try to build, but they get stuck, and then they will need engineers. The sheer volume of product built by both experienced technical companies and non-technical novice startups and founders and wannabe founders is going to be massive. That is the bull case for having more software engineers needed in the near future.

On the other hand, in a year or so, people will build all these products, and most of them won't be able to market them, sell them and make money. Eventually, there won't really be a need for that many software engineers.

I think overall the bull case is probably going to win net net.

greenavocado•48m ago
Meta is back in the game, albeit not at the top. Impressive stuff, nonetheless.
qpricjalcbeu•41m ago
Weren't they caught multiple times gaming the benchmark even more so then the rest?
alansaber•40m ago
Let me assure you, literally everybody does this
zmmmmm•18m ago
Yes and Zuck effectively disbanded the entire team that did that. Not saying we shouldn't cast a critical eye on it, but it probably does warrant a second chance.
qpricjalcbeu•4m ago
Zuck was part of that team.
cpt100•37m ago
They are not open source anymore, right?
fau•46m ago
"We're thrilled to be releasing Muse Spark 1.1, a testament to our research momentum."

Let's see how it does on the Creative Writing bench ;)

EgregiousCube•44m ago
Their published benchmarks seem to indicate that it's pretty good at coding and multimodal, but VERY good at successful tool calls.

What kind of use case would be best for that shape?

alansaber•42m ago
This sounds... kind of useless? Really good JSON or similar constrained decoder performance is interesting, but normal decoder > tool validator loop with good error message > tool retry is almost always able to get a tool to work second try, and input is cached so it's not expensive.
aldanor•33m ago
Things are not always that simple, eg https://lucumr.pocoo.org/2026/7/4/better-models-worse-tools/
winstonp•29m ago
The avg coding session has hundreds or thousands of tool calls. Even a 5% failure rate noticeably notches up token use and cost. See Gemini.
alansaber•25m ago
Yes, but each tool call has a different failure %. The tool calls that make up the majority of volume like grep are going to have nowhere near a 5% failure. A custom user-defined skill having a 5% failure rate is probably fine.

lnenad•38m ago
Considering the DeepSWE result (imho if you're gonna give value to benchmarks this is one of the best) it's not good enough.
svantana•15m ago
It's a high quality benchmark for sure, but it being public means it's at risk of leaking into the models (unintentionally or not), right? For that reason I prefer to look at the private ones, like: HLE, SimpleBench, Kagi, ARC-AGI.
qpricjalcbeu•37m ago
Yeah, no thanks. I cannot think of a worse company to trust with additional personal data.
niek_pas•33m ago
Me neither, though LLMs also provide services that don’t involve personal or sensitive data
frangonf•37m ago
Is this the model trained on Meta "draftees"? Are we seeing this in the jump on JobBench?
Jcampuzano2•35m ago
Competition for cheaper and efficient models is a good thing, regardless of if you don't like SpaceX, Meta, etc. Especially from US based labs

I for one am really glad to get competitive models that will push the major labs to bring prices down. While Chinese open source labs are also great, unfortunately when it comes to US/Western political pressure it won't often have as much of a bearing on labs bringing prices down, especially for enterprises.

Also if these numbers are true, this is truly breaking ground finally for Meta.

zb3•33m ago
This is not open-weights, right?
EgregiousCube•19m ago
Correct
phillipcarter•31m ago
My trust factor is gone with Meta right now. Has there been any independent analysis to confirm they didn't cheat on benchmarks again?
guluarte•30m ago
A lot of these benchmarks are unfamiliar. Are labs just choosing the ones that make them look best?
carimura•26m ago
I missed the fact that Meta was developing and releasing closed-weights models... bummer. Would be great to see some more progress with American open-weights models.
anthonypasq•23m ago
Everyone has been loving to shit on the Alexander Wang acquisition but this seems legitimately impressive to me?

Meta's AI org when from a total mismanaged dumpster fire for multiple years to delivering a competitive model in less than a year on essentially their first try?

paxys•18m ago
How is it their first try? They were leading the race with Llama 3.x a few years ago.
GodelNumbering•22m ago
Lot more details in the linked report https://ai.meta.com/static-resource/muse-spark-1-1-evaluatio...

From Terminal-bench-2.1 details,

> We use a bash-tool-only agent harness to evaluate 89 Terminal-Bench 2.1 tasks from the official repository, where resources are capped at 6 CPU cores and 8GB RAM.

This disqualifies the results. Each terminal bench task has a cpu upper limit and RAM upper limit. Overriding either is disqualification.

For reference, in tbench-2.1,

1. 0 out of 89 task allow 6 cpu cores (highest is 4, and i think only 1 task)

2. 8 out of 89 tasks allow 8GB RAM

This kind of shady benchmarking (I was talking about it just yesterday in a different context https://news.ycombinator.com/item?id=48838212) takes all joy out of building a harness to improve benchmark performance of a model because no matter what you do, you won't beat the headline (cheating) number. This is presumably why this model is not in the official benchmark leaderboard https://www.tbench.ai/leaderboard/terminal-bench/2.1

As an ex Meta employee, this is a little sad but not massively surprising. 'Number go up' is the core performance evaluation metric until PSC is done and you move on.

paxys•21m ago
How is every company able to show itself at the top of every benchmark?
zmmmmm•14m ago
Good to see Meta finally back to releasing something at least worth evaluating. And it sounds like they did at least a bit skate to where the puck is going by focusing on tool and computer use.
NitpickLawyer•9m ago
How are people trying this? I don't see it on openrouter. Any ways of testing this without subscribing to meta stuff?

And those people won't need to be software engineers.

> but they get stuck, and then they will need engineers

You've implicitly assumed here that the AI systems will always be worse than the average engineer. That is IMO myopic. I'm not sure that it's even true now let alone in the nebulous future.

throwaway27448•16m ago
> And those people won't need to be software engineers....You've implicitly assumed here that the AI systems will always be worse than the average engineer.

Most of what we do as engineers is precisely describe or analyze the behavior we want or the behavior we don't want. All other engineering skills that are useful are ultimately downstream from understanding the behavior of software enough to know which parts to keep, improve, or jettison. Chatbots can take care, somewhat, of analysis or expansion of instructions.... but they can't read minds. I don't see that changing any time soon.

linkjuice4all•30m ago
I see some similarities to 3D printing here. It’s great that everyone can make their own toothbrush holder (or whatever) but I’m probably not going to pay for someone’s weekend project.

I’m “seeing” more devs stepping into the SendCutSend stage where they’re cleaning up/fixing/productizing vibe coded projects so maybe there will be some new demand in that space?

Lomlioto•29m ago
At least in China a lot of software developers are now struggling.

I think for a lot of type of software we have now reached peak employment.

Someone payed a few k just for a normal website.

ianm218•20m ago
> At least in China a lot of software developers are now struggling.

Do you think that Chinese software industry is that relevant to the kind of software market talked about on HN? I.e. lots of enterprise b2b and infra companies.

Chinese companies have always had a very low willingness to pay for software which kinda breaks the flywheel of B2B SaaS companies and companies to service those companies all the way down.

wolttam•32m ago
To expand on Chinese models:

- DeepSeek

- GLM (Z.ai)

- Minimax

- Kimi (Moonshot)

- Hy3 (Tencent)

- Qwen (Alibaba)

(Each one of these with weights available to download and run locally)

4d4m•23m ago
GLM 5.2 is great, but is so rate limited now I no longer recommend it
wolttam•18m ago
I'm looking ahead to the next wave of open-weight models that are as efficient as DSv4 (which is really efficient), and have been heavily distilled on GLM 5.2 (which is trivial, given it is open weight)
croes•32m ago
While data centers are still using lots energy created from fossil fuels and many still evaporate water for cooling?

No wonder we still can’t get climate change under control

Lomlioto•30m ago
Its the biggest technology race we have ever seen. Richest companies, smartest people, richest countries.

I do not know if competition is good, we will see in a few years.

Looking forward having a physical job for a change :D

pa7ch•26m ago
A bit much describing our tech leadership as smartest people we've ever seen.
anematode•25m ago
Greediest, perhaps?
Lomlioto•22m ago
I would call the founders of DeepMind (Demis Hassabis, Mustafa Suleyman, Shane Legg) very smart people. Im pretty sure with the amount of funding everyone of these companies have, they have a long list of very smart researchers in their companies.

I do not mean Suckerberg or Eric Schmidt.

34m ago
Debugging and diagnosis is very tool call heavy, whether that's grepping / transforming logs, calling out to profilers/tracers, or even just writing up incident reports.

Bug diagnostics is about being okay at coding but better at tooling.

Given a good diagnostic report, it can be handed to opus for the fix.

Opus is okay at writing reports, but it still regularly gets table widths wrong in typst documents, leaving the last column full of text but only a handful of characters wide.

paytonjjones•26m ago
I wonder if we'll start to see that pattern with every new release. Tool use likely changes rapidly, so the newest, rather than most intelligent, model may always have an edge.
