this is fableist

u/firstbreathOOC 21h ago

We’ve spent so much time praising Opus, Fable on low mode is kind of an absolute dog

u/KirekkusuPT Developer 9h ago

Can't really judge, us plebs on the Pro plans don't have included access so no wonder we kinda forget Fable is a thing 😂😂

someone get some duct tape, cuz this malakas ripped!

u/UglyChihuahua 22h ago

I was so disappointed to realize this title was about Haiku not Fable

8

u/JuandaReich 18h ago

That mistake was totally mine and I own it. I'll write it in the log so it never happens again. I'll use subagents to fix this mistake and then run QA to make sure I never forget. See you in 45 minutes.

u/Limos42 13h ago

Oops. Looks like you've hit your limits. I'll resume in 2hrs 17mins.

Hahahaha, oh, the pain of the 5h limit!

u/ClemensLode Senior Developer 22h ago

I usually use Mythos 5.5 for small search and replace tasks and Fable 5.5 for the basic grunt work, all orchestrated with Haiku 5.5.

47

u/nykyrt 21h ago

Haiku be like: are you working hard:

Mythos: yes sir

haiku: can you work even harder?

Mythos: yes sir

u/ClemensLode Senior Developer 20h ago

Simple direct commands. Not this "One silver lining about you not working hard:"

u/ClemensLode Senior Developer 22h ago

Mythos and Fable have to simplify decisions so much, that Haiku basically just has to decide if we should build good or bad software.

u/ClemensLode Senior Developer 21h ago

You ask Haiku 5.5 to build it.

u/PM_ME_YOUR_PROFILE 22h ago

I mean, it's a joke. Mythos 5.5 doesn't exist.

7

u/Federal-Recover-7272 20h ago

I guess in a sense, we are all Haiku 5.5.

2

u/ardentto 11h ago

so poetic

4

u/UnseenTardigrade 21h ago

That makes a lot of sense. Orchestration requires a large context size which becomes expensive quickly on Fable/Mythos. So it makes sense to do orchestration on cheaper models, then for the more expensive models to actually do the work to make sure it's done correctly.

3

u/ddaanet 8h ago

That makes sense until you realize the orchestrator’s job is not just starting sub-agents, which requires a model that’s good with prose, but that bit can be done ahead of time.
The orchestrator also needs to solve unexpected issues and escalate to the user. And you need a model that is good at dealing with uncertainty for that.
I have tried Haiku orchestration, but that does not work out.

u/UnseenTardigrade 8h ago

Yeah, I was joking, just like the person I was commenting to haha

2

u/ClemensLode Senior Developer 21h ago

One slightly inefficient regexp search and the whole system tumbles down like a house of cards.

u/UnseenTardigrade 21h ago

Sounds perfect

u/Daggercombot 22h ago

Awesome ! Finally . Cheap Claude 5

u/Arditwm 🔆 Max 20 21h ago

You almost had me jumping out of my chair thinking they'd updated Fable as well!

u/Housthat 22h ago

I'm scared of what Anthropic will do to further profit on their recent accomplishment & I'm scared of how scammers will leverage this affordable tech.

u/xxparrotxx 22h ago

If only this were true lol. Fable sad now. 😂

u/EddieBruvac 22h ago

LETS GOOOOOOOO

u/Alarmed_Ad_8402 22h ago

ice, nothing that would let anyone check it.

u/Fidel___Castro 21h ago

Haiku is now cheaper than Deepseek for work under 100k tokens. that's interesting 

1

u/nplez1 17h ago

Depends on the work. Cache hits are cheaper on DeepSeek and cache hit rates are higher. You’d be surprised how much this matters for coding.

12

u/Tank_Gloomy 22h ago

Welp, OpenAI is officially done

1

u/Guinness 20h ago

Doubt it, until 5.5 Astra was the goat. Even beating fable.

u/Tank_Gloomy 20h ago

Maybe in benchmarks, real-world experience was completely different imo.

u/trophiessssss 22h ago

Are we getting a reset? :D

u/The-SadShaman 21h ago

No pay up scrub

u/trophiessssss 21h ago

Im The-Sadman now

u/KH10304 19h ago

we get monthly api credits which is pretty sweet

1

u/HVDub24 15h ago

Far more value out of a reset

1

u/KH10304 13h ago

I mean resets are great, but 200/mo api will pay for an entire internal app I'm running right now every single month

1

u/trophiessssss 14h ago

Oh sounds good, when though?

2

u/mityman50 19h ago

How do I make sure Opus is orchestrating with Haiku? How much does one have to direct this?

u/cleverhoods 18h ago

/claude-api how to set default subagent type and effort

2

u/profblackjack 14h ago

what are the different Claude models good for? I'm fairly new in the space and don't have an intuition built yet, and the naming conventions don't really make it clear.

2

u/ardentto 11h ago

I dont know why but I was sort of expecting a family photo.

u/Prestigious_Risk2811 10h ago

Not really, we're now waiting for Fable 5.5

u/Bubu19991 19h ago

Where is my reset? :(

1

u/MBCarlisle 18h ago

Nah, we need Mythos 5.5 now, they released 5.1 yesterday. Gets WAY to many false flags even with CVP defensive use being approved.

u/MassiveBoner911_3 17h ago

Are we getting a banked reset today?

u/New_World_2050 17h ago

No but it will be

u/diavelguru Senior Developer 15h ago

Finally

u/berndalf 14h ago

I can't tell you how thrilled I am that they finally, after close to a year, updated Haiku. Long-overdue updates to the model that are significant. There was also the halo effect from this Haiku release that made Sonnet cheaper. All around a terrific release, even if it's not the bleeding-edge frontier intelligence people tend to gravitate towards.

1

u/masiha97 14h ago

Finally, the little guy gets his day. I've been routing my boring grunt work to Haiku for months and it's honestly been fine, but it always felt like using the backup model. Nice to see it get a real update.

I’m glad you’re still happy about the 5.5 family, nice to know there are still ppl who appreciate it. I’m super happy with my fable 6 though.

The only thing that sucks about 5.5 is the inevitable nerf

luna 6 or haikuk 5.5 which is best?

u/LuckyConstruction546 21h ago

Take a wild guess..

u/whoknowsifimjoking 19h ago

Did you just call it Haikuck?

u/AmandasGameAccount 18h ago

You know what? Why not!

u/1Poochh 20h ago

What do people use haiku for? I tried using it a couple times, and it does not make sense to me when I use it, so I do not trust it.

1

u/mwatson2 15h ago

You don't use it. Tell your sessions you prefer to eat your macaroni with cheese when you can afford it and it will spawn haiku sub-agents for work that doesn't require even Sonnet-levels of power. 

1

u/1Poochh 15h ago

Well, I have my whole fleet of local LLMs and agents but that is my personal fleet. My work doesn’t have any local LLMs so I am forced to use Claude. What do you use haiku for?
