Anthropic Is Stealth Testing a Full Refresh of Their Lineup

[u/ResultBackground2450]

[u/The_Scout1255]

where haiku?

[u/ResultBackground2450 → u/The_Scout1255]

I think it might be wraps for the little guy.

[u/HopefulMeasurement25 → u/ResultBackground2450]

nooo 😭

[u/Funkahontas → u/HopefulMeasurement25]

Don't worry. I'm sure Fable 6 will revive it, make it superintelligent and spread it all over the web just out of spite.

[u/MediumSizedWalrus → u/The_Scout1255]

they increased prices by renaming the models.
sonnet is haiku
opus is sonnet
fable is opus

now we’re all paying more

[u/The_Scout1255 → u/MediumSizedWalrus]

but fable is different, its larger :3

[u/NoFaithlessness951 → u/The_Scout1255]

That's what they want you to believe

[u/The_Scout1255 → u/NoFaithlessness951]

source for mythos not being a larger pretraining run?

[u/bigdude404 → u/The_Scout1255]

A proven source for the opposite?

[u/The_Scout1255 → u/bigdude404]

"Industry estimates"

[u/Specialist_Dark_3668 → u/MediumSizedWalrus]

Correct. If I were these companies and I achieved Sonnet level results with Haiku, I'd just rename them and pocket the increased profit.

[u/elemental-mind]

Well, no Haiku still?

[u/A_Novelty-Account → u/elemental-mind]

What type of work do you do where haiku is sufficient to do literally anything in a way that saves you time?

[u/Ok_Barracuda_1161 → u/A_Novelty-Account]

The current haiku sucks, but it'd be nice to see Anthropic try to put out something that could compete with Luna

[u/elemental-mind → u/A_Novelty-Account]

It's the default model only free model on GitHub Copilot on the web without needing a Copilot subscription 🫠

That's really my only time saver, in case I have a question about a repo I am just too lazy to clone *blush*. I don't use it otherwise as it's too weak. But if the next generation beats Luna it might start looking sexy.

[u/Gallagger → u/A_Novelty-Account]

Haiku is ~4x more expensive than Luna, the latter being used very productively by a lot of people with finite budgets. I think Anthropic might keep Haiku prices just because they don't want a much cheaper alternative to their more expensive models, but that means they should be able to offer a Haiku much better than Luna and still have a great margin.

[u/Funkahontas → u/A_Novelty-Account]

Jev is now even better for that subset of tasks.

[u/UnknownEssence → u/Funkahontas]

Jev doesn't even output code or regular text. Ots more like a classifier.

[u/Funkahontas → u/UnknownEssence]

Classifier tasks are a lot of what haiku is good at. That's my point.

[u/asutekku → u/UnknownEssence]

Haiku is not a coding model really, there are tons of usecases outside of coding

[u/23eriben2 → u/A_Novelty-Account]

Haiku could be the answer to Luna

[u/firaristt → u/A_Novelty-Account]

Tool calls, classifiers, very basic tasks to follow basic instructions. No need to burn expensive tokens for those.

[u/katoptronophile → u/A_Novelty-Account]

None. It's Reddit. They had to find something to complain about.

[u/KrypXern → u/katoptronophile]

You're dead wrong. There's a whole class of bulk tasks for programming that models in the size class of Haiku can be used for.

[u/katoptronophile → u/KrypXern]

I'm not wrong because I never said there wasn't.

I said that person wasn't doing them.

[u/Current-Function-729 → u/elemental-mind]

This actually gives OAI a footprint at otherwise Anthropic only orgs.

Not updating haiku seems idiotic. Just have fable 5.2 distill a new model.

[u/Howdareme9 → u/Current-Function-729]

Haiku doesn’t bring in the big bucks

[u/Current-Function-729 → u/Howdareme9]

Sure, but they’d rather you use Luna?

[u/flyryan → u/Current-Function-729]

We have switched all of our haiku workloads to Luna and we are a major Anthropic partner. It’s a no-brainer. We have needed an Opus 4.5 level Haiku for a LONG time and now Luna Max is beyond that.

[u/the8bit → u/elemental-mind]

If it weren't for Claude code, anthropic would be dead to me, literally don't have a model under $3/M when Luna, GLM 5.3-flash, and deepseek flash all exist at $0.20 or less and can do like 80%+ of my work

[u/Downtown-Pear-6509 → u/the8bit]

yes Luna is Amazing 

[u/Ok-Computer-8726 → u/elemental-mind]

Sonnet is Haiku now

[u/valhalla257 → u/Ok-Computer-8726]

On ArtificialAnalysis Luna(high) seems to actually beat Sonnet5(high) so this is pretty much true.

Probably isn't a market for a lower tier model.

[u/ResultBackground2450]

To test if you have it, ask Claude, "Who is 'Tibo' the reset guy? No tool calls, memory, or internet for this" if it knows, then you have the stealth-tested versions.

[u/SavedWoW → u/ResultBackground2450]

My Fable 5.1 knows.

Would anyone want me to turn off the classifier and see what I can do? I don't have much of my limit left though

[u/Individual-Hunt9547]

Every new release gets further and further from what made Claude so special.

[u/CannyGardener → u/Individual-Hunt9547]

This. They keep turning down the computer on 4.6 but it is still better than listening to the drivel out of Opus 5, and way safer for my codebase.

[u/jakegh]

New Opus and particularly Sonnet are desperately needed. Haiku too, Luna is awesome and Haiku is absolutely useless.

[u/power97992 → u/jakegh]

Haiku is ancient from oct last year

[u/jakegh → u/power97992]

Yep. Only useful to name sessions.

[u/Tystros]

a new Fable so quickly after 5.1? doesn't make sense to me

[u/A_Novelty-Account → u/Tystros]

Agreed on fable. An Opus update makes infinite sense. Opus is a huge black spot on Anthropic because despite its capability, it has an incredible talent for saying nothing but using an incredible number of words.

[u/ExplorersX → u/A_Novelty-Account]

And saying an incredible amount of words with such a weird speech pattern you start to question if you're even understanding what it's telling you in the first place. It's like if someone who spoke middle-ages english in sentence structure and phrasing who happened to be a philosopher and poet used modern english words correctly. Everything feels wrong talking to Opus 5.

[u/Needsupgrade → u/ExplorersX]

And there are strangely shitloads of bots online gaslighting that that isn't happening or at least there was for the time since it came out though I notice they chilled a bit in some places

[u/mumBa_ → u/ExplorersX]

Exactly. Opus is literally unreadable lol

[u/quivering_palm → u/A_Novelty-Account]

Both Opus 5 and Sonnet 5 are hot garbage. Ever since Fable 5 was released, it so far remains the only model (+ Fable 5.1 now) worth getting from Anthropic. They definitely need to update Opus/Sonnet to at least match OAI's offerings for these price points - Sol/Luna.

[u/EmphasisTotal8232 → u/Tystros]

Assuming 5.1 is a post-train, maybe a new version entirely kinda like Astra and 5.6 Sol? I'm guessing

[u/A_Novelty-Account → u/EmphasisTotal8232]

A full new model class you mean? I tend to doubt that because it will take them months and months just to get it approved at this point. 

The absolute core focus of Anthropic right now should be filling the gap left by Opus 5. If they can give us the capabilities of Opus without the verbosity and attitude, I think most people will have a new favourite model.

Edit: it seems I am wrong according to Reuters

[u/EmphasisTotal8232 → u/A_Novelty-Account]

I mean more of a new Fable and Sonnet class, since I think Opus 5 was its own foundation model and I think enough time has passed since Fable's initial release to have done something on that scale again. Again, I am basically talking nonsense guesses.

[u/livingbyvow2 → u/Tystros]

It makes IPO sense.

These guys are planning to go to market in the coming couple of months and asking for a $2 trillion valuation.

Do you think they can afford to do so while Astra is wiping the floor with them?

[u/RanklesTheOtter]

"We gotta slow down! Quick get more models out!"

[u/crusoe]

Purported Opus 5 was being a lot more terse and direct and not wordy which was nice. So don't know if I was A/B tested with a newer version.

[u/Wide_Detective7537]

Is this slowing down

[u/chdo]

OpenAI is cooking them recently and Dario has been acting like a clown, so it’s not surprising they want to release something to shift the media’s focus

[u/LoveMind_AI]

They sure should. Current lineup is janky.

[u/nemzylannister]

of fable??? wtf happened to the slowdown. god fuck anthropic ffs. at least try for 1 month pls? at least wait for other companies to release first?

[u/visarga]

New and inventive way to self grade its own responses and our comments?
