There are so many derisive comments here.

David Ha, CEO and co-founder, was one of the youngest managing director at Goldman Sachs before doing ML at Google. His ML publications were considered top-notch almost a decade ago. I had high hopes for him when he raised money and founded Sakana.

I do agree with some comments here that perhaps this particular product is not well thought out. I also agree with the criticism that David calls Sakana a frontier AI lab while making money just selling AI B2B applications to Japanese businesses. I also agree with the assessment that Sakana has abrasive and antagonistic, sometimes openly hostile, recruiting tactics. I also agree that his then-impressive publications may have lost their luster in the age of LLMs.

However, the man is clearly driven; and he and his team may have more to offer in future. I admire the man for not taking the conventional AI-research career path.

Indeed. The world models research many labs are now chasing was to some degree ignited by David Ha and Schmidhuber's 2018 paper.

More broadly, Sakana is pursing a refreshingly distinct research path, with their focus on evolutionary methods, biological intelligence (e.g. continuous thought machines) and open publication.

Kind of shocking - a model comes out that beats mythos and offers a reasonable price and it ... gets downvoted?

Probably taking hate from both sides - OpenAI / Claude fans who are undercutting its moat. Chinese open-model fans that want it to be cheaper.

But it's a genuine accomplishment to hit those benchmarks and offer a reasonable plan?

Bizarre reaction TBH.

Which model is that? What is it named?

Not OP but I believe it’s Fugu (7B). According to [0]: “Fugu itself is a trained coordinator LLM.”

Looking at the technical report I'm a bit confused. The improvement from using their orchestrator models seems minimal (in some cases lower than just the model which I'm assuming is in the orchestrator's pool?). Maybe it's sort of acting as an additional reasoning step upfront? Sort of like how if you asked Claude to create a plan for how best to prompt itself, you would probably end up with a better result than just the base prompt.

Also, from the technical report, looks like they're training on the output of Claude Code, etc. I'm guessing this doesn't violate TOS because they're technically not a directly competing model. This brings me to what I see as the main risk with this service, which is that it seems like an easy thing for a frontier lab to make obsolete, either by models beginning to converge in terms of strengths or by improving their own harnesses to include more of this meta-reasoning.

As a developer outside the US I think it's vital to have alternatives to OpenAI and Anthropic, but sadly this is not it. For $200/month you get < 3 hours of use per week, the API is extremely slow, and the output quality in my tests is nowhere near Fable. It's nowhere remotely near usable as a day-to-day workhorse. Very disappointing.

u seem to be the only one who used it here - how did it compare to opus and gpt5.5? in theory it should be at least on par if not better at times right.
cortesi 1 day ago||
I only had time to use it for a couple of deep reviews of large Rust projects, and a few agentic coding tasks (implement plan X, refactor Y in fashion Z) before my quota ran out. My impression is that the reviews were quite strong - maybe Opus 4.8+ or around GPT 5.5 (for my particular use case) - but very slow. For implementation I found it weaker, it made a few mistakes that I haven't seen frontier models make in a long time.

FWIW, I've just published this interview with David Ha an hour ago.

We talk in detail about Fugu and why these kind of routing models are likely to win out over the big frontier models.

He makes some very good arguments for them.

I tried running this for some market research for my startup and it did a pretty nice job. It didn't necessarily find any obscure data, and it seemed to rely on older data than what I could find myself. On top of this, it had the same sycophantic tendencies as most LLMs these days (explaining why your idea is great and riffing on that), which I find to be unnecessary use of resources.

All put together, paying ~$60 to get a hit-or-miss report seems a bit excessive, but obviously as the models they use under the hood get better it becomes more and more worth it, assuming they also improve their grounding/search capabilities.

I'm a big fan of Sakana though, and have followed David Ha / @hardmaru since the world models papers (with the racing car game and the Doom clone), which were incredible at the time.

You pay $200/month to Anthropic, $200/month to OpenAI, $200/month to Cursor, $200/month to $200/month to Google, and seeing that it didn't come to a nice round $1024/month, you pay $200/month to Sakana to coordinate it all, because why not.

While you're at it, feel free to send me $200 as well, I'll generate a crypto address ending with "AI".

My current setup:

    $20/month: Claude Code
    $10/month: Minimax
    $16/month: Xiaomi Mimo
    $10/month: Opencode Go
Opus at low/medium effort generates plans. Then several coordinator/worker pairs are possible: DeepSeek v4 Pro + Minimax M3, Mimo v2.5 Pro + Mimo v2.5, Mimo + Minimax, Sonnet 4.6 + Haiku. I've been running hundreds of long multi-agent sessions, topped up extra credits here and theere, but haven't reached $200/month spend yet. Relying entirely on Claude/Codex feels like a waste of cash now.

TIL: I just found out that base58 disallows I (capital i), l (lowercase L), O (capital o) and 0 (zero), so I could only generate GrxoJt4eNXE2QaQ55iPSa7hhiYdzCo8ZeAuokmh2Cai.

(don't send anything, sharing only because of the base58 fun fact I didn't know)

IdiotSavage 1 day ago||
More fun facts:

Omitting those characters makes it good for generating passwords if they need to be typed in by hand.

Double-clicking a base58 string always selects the whole string and it doesn't wrap accidentally, thanks to missing / and +, so it's also convenient to copy and paste.

Unfortunately, no special characters means that a base58 string will often be rejected as a secure enough password.

Pay $0 to run a local model or even a cheap DeepSeek V4 model via their API which is close to free per million tokens.

These prices are just going to get raced to $0.

a2128 1 day ago|||
I used to have a $20/mo ChatGPT subscription and now I spend $12 per year using Kimi models on OpenRouter, and that's with zero-data-retention-only providers (some models sometimes have free providers with scary tracking). Maybe I just don't use that many tokens, I don't fill the context with more than what's needed for a specific request, but it goes to show how these subscriptions can be an absolute ripoff. The thought of spending 200x that is insane to me
mark_l_watson 1 day ago||
The beauty of your approach: when people are not paying for an expensive subscription, they can decide to use models less and not feel like they are leaving money on the table.
goodmythical 1 day ago||||
Where do you acquire free hardware and free electricity such that you can host local models for $0?
qainsights 1 day ago||||
Not everyone can run local models. It is also expensive will be outdated soon as the model evolves.
kijin 1 day ago||||
Not while the hardware required to run a local model at an acceptable speed costs way more than $200.

Guess what, the big players are hoarding all the RAM and GPUs so that other people can't afford decent hardware. It's working out beautifully for them!

sofixa 1 day ago||
> Not while the hardware required to run a local model at an acceptable speed costs way more than $200

It's $200/month. You have to take into account energy costs and all the rest of a system, but if you break even within 1-2 years ($2400-$4800) it'd be a pretty good deal. And $4000 buys you a pretty decent system.

kijin 1 day ago||
Sure, if you're going to keep using it long term.

But it's a hefty upfront investment for people who just want to experiment. The good thing about $200/month subscriptions is that you can cancel them any time and cut your losses. Not so with a $4000 computer that loses half of its resale value as soon as you plug it in.

I think the current sweet spot for people who don't already own a high-end gaming PC is to rent a server with a beefy GPU from Hetzner et al. and run local models there.

holistio 1 day ago|||
Maybe. But for now it's fascinating how $200/month has kind of become a normal tier.

It's similar to how AirPods normalised all of us having $300+ headphones. All of us would have scoffed at the idea a decade ago.

p1esk 1 day ago|||
Many people here spent a lot more than $300 on headphones long before AirPods appeared.

Those were hobbyists, audiophiles, professionals, artists (recording, performing, etc.).

I think OP meant noise-cancelling headphones, which were fairly ubiquitous in tech circles in open offices; before Apple launched AirPods.

But, it is not all about cost: models like DeepSeek v4 flash (I use the US company Fireworks.ai and also buy tokens directly from DeepSeek) is very fast, very low latency while working.

Would you want to use a text editor that updates the screen very slowly? Kind of the same thing for using agentic systems as coding assistants: don’t want a ‘sluggish’ experience.

erispoe 1 day ago||
I have, mostly, long running autonomous tasks, so it doesn't matter how slow inference is. If I optimize for latency it means I'm turning into the limiting factor.

The Sony WH-1000XM series and the Bose QC35 were the standard quality headphones years before AirPods were a thing, and both retailed at $300+.
holistio 1 day ago||
Of course, premium headphones existed before. I have a WH-1000XM4 sitting right next to me.

But your aunt Josie didn't have one. Now Apple is selling 80 million units / year and the ~$300 price tag has become normal. Before that, most people had headphones that were 10 times cheaper.

Hamuko 1 day ago||
$300 isn’t what AirPods cost though. You can get a pair of AirPods 4 for $129 on Apple.com, and I presume that is still the most popular model. If you’re paying ~$300, you are buying premium headphones.

The base model where I live (Central Europe) is $194. The Pro is $357. The Max is $779.

Happy user here, pairing it with Composer 2.5, with Fugu Ultra as advisor and Fugur as planner. For scope/architecture it’s on par with useful Fable-style orchestration than one chat thread.

I've been shipping production on archive.tw with Fugu Ultra in /advisor on oh-my-pi.

Advisor doesn’t slow the loop if the driver stays fast. Worth it if your harness can split advisor from worker.

Beta user: they piloted OpenRouter fusion before it was seen as the viable step. Everyone's understood for months now that having different models check each other is the best path forward.

This gets you that in a nice neat package, without the underlying tinkering mechanics.

If (big iff) the usage mechanics work out, then this is actually a really good anti-big-model strategy.

They'll be incentivized for your success, not token-maximizing for their investors.

The team is super smart too. What's not to like?

Wishing them the best on launch.

if you've used codex or claude, how do the usage limits on fugu feel compared to the pro plans on either? honestly wouldn't mind subscribing to this if it's as generous as what codex is giving me monthly, which seems unrealistic.
epsteingpt 1 day ago||
Hard to say - since I used it in Beta with free credits, where the usage felt more 'Opus' than 'ChatGPT' but more efficient token wise. Switching models every time is annoying.

But their paid plans I'm not sure yet - planning to subscribe and can let you know.

Almost no chance it will be as generous as OpenAI though. They just don't have the money :-)

> Frontier-level performance without single-vendor dependency. [...] Plug collective intelligence directly into your workflows today with a single API.

Does multiple vendors run this "single API" or how is this not replacing a single-vendor dependency for another single-vendor dependency?

Lwrless 1 day ago||
Got myself the $20 subscription and tried it out. The 5-hour limit runs out surprisingly fast. Quality is okay but it feels slow, and even with my $20 Claude subscription on Fable, the credit usage ends up being lower. Fable usually catches issues in my Opus 4.8-generated code that I'd miss otherwise, but Fugu didn't. Makes me wonder if it's really at the Fable level. Hard to see the value here.

ngl, I thought sakana.ai was doing cooler stuff than this. that said, the release of a product like this makes sense because it follows your natural intuition when using these models. The best way to use LLMs is to have at least two in your pocket, because the models do a good job at covering each others assets and filling in obvious model-specific blindspots.

it's interesting that they're offering in the form of fixed cost subscription plans too. My impression was that the first party providers can do this because they api inference margins to the tune of 80ish percent. Anyone else orchestrating on top of these models have to pass through these costs or eat it themselves.
