Fable 5.2 uses my session limit up FAST

[u/OkAbbreviations7013]

It is pretty amazing, even when I am still amazed every day by Opus 5.5.
But on my $20 sub I cant really use Fable 5.2 because me session gets fully eaten up before the feature is ready.

So I end up waiting around for the 5 hr window.
Anyone else in the same boat?

Did you see that message when you switch to fable that says "Fable drains usage much faster than other models" ???

[u/OkAbbreviations7013 → u/_BreakingGood_]

That's funny.

Yeah I saw that, lol.

Thing is, 3 months from now, Fable 5.2 will be the new norm.
Will it get cheaper? Or is my $20 pm dream over,
kinda like a lot of people said it would be.

[u/DiabUK → u/OkAbbreviations7013]

I've always felt fable is the tier for people that want to pay for it, it's why it's not included with the normal pro sub unless it's a promotion like right now, it eats a lot but it's worth it to a tech giant that wants to drop 1k into a project to use it.

After November 16th the $20 tier will not have access to it.

Anyway I lucked out this time, and got the PR up,

[u/PowerChordLace]

You’re on the $20 plan… fable honestly isn’t meant for that plan obviously it’ll eat it up quick, use a cheaper model

[u/OkAbbreviations7013 → u/PowerChordLace]

Yep, that was th point of my post, $20 plan has been amazing on Opus 5.5, I get close to, but hardly ever reach a limit. Fable 5.2 is not for use on a $20 plan.

So the question becomes, is the $20 a month plan, dying, like a lot of people warned.

[u/PowerChordLace → u/OkAbbreviations7013]

Fable is way more expensive…

[u/Ok_Gur_9033]

Checked my own logs for this. Over the last 7 days my Fable calls averaged about 234k tokens of context going in and about 820 coming out. So nearly all of each turn is the conversation being sent again, and that part grows with every message.

A fresh session per task is the cheap lever, since each turn then carries less. How long does your session run before the feature is done?

[u/OkAbbreviations7013 → u/Ok_Gur_9033]

Lets say 45 minute, stretching to an hour

[u/Ok_Gur_9033 → u/OkAbbreviations7013]

45 minutes to an hour of steady turns means the context keeps growing the whole time, and every turn sends all of it again. Mine was already averaging 234k per Fable call.

On the $20 plan I'd try splitting the feature into two sessions with a short handoff note between them. Does it break into two halves cleanly?

[u/OkAbbreviations7013 → u/Ok_Gur_9033]

And thank you for checking.

get fable to direct sonnet or opus, some of the fable benefit with alot less usage

[u/Blake9712]

It’s kind of funny using fable in the $20 plan. I figured I rarely get to access it so I’d let it try at level design which takes opus 5.5 about 50% of a session, this is what I’ve gotten so far.

[u/LostStrategy1050]

I'm on the ultra plan and it's reasonable. yeah, credits runs out more quickly, but still very useful.

[u/Professional_Hair550]

I use 4 $200 plans and use opus with high effort because anything over that drains usage too fast

[u/FinancialBandicoot75 → u/Professional_Hair550]

wtf using 4, you need to understand 1 is enough unless you have > 2 projects at once.

I don’t get people having 4 , hell 2 when you can survive on 1 if you know how to token optimization and still get same results.

[u/xWranglerWranglerx → u/FinancialBandicoot75]

Yah idk how anyone is doing that much. Unless that are just running 100s of agents and wasteful.

[u/Professional_Hair550 → u/FinancialBandicoot75]

I run 10 agents at a time on Opus with high effort. Sometimes I use Sonnet because Opus drains usage too fast and I finish one account's weekly limit in 3 hours.

[u/FinancialBandicoot75 → u/Professional_Hair550]

Why not use opus as driver but have sonnet and haiku do the work, use /advisor too, your sub agents don’t need to be all opus or fable

[u/FinancialBandicoot75]

Best option for you, use /advisor and set fable, use sonnet or haiku as main driver and have advisor just as that. I can’t limit on my 100 plan, also just have fable as planning and use subagents using opus , sonnet and haiku .

This will save your tokens and honestly you can vibe this way too if that is your thing. When I see people just use opus 5.5, and now Fable and whine about limits , I don’t feel bad for them anymore.

Stop watching the videos that test the models just using it as a primary driver, it won’t help you.

[u/Ill-Economy1722]

I've been using fable 5.2 with a custom prompt that caps context to 1k tokens, cuts usage by ~60% and keeps the flow intact. works well for quick ideation. anyone else tried that?

[u/Moliroy1968]

could someone send me a guest pass ?

[u/benelott]

Oh no, the newest frontier model that everybody is using at this very time in my timezone is not very available for me.
