T3 Stack creator Theo Browne requests feedback from users who tried software tool Fable and were unimpressed

1. Can you share some of your prompts? What was disappointing about the result? 2. What harnesses are you using? Claude code? Cursor? 3. What is your usual daily driver right now? 4. What's the biggest task you've ever seen an agent complete without human intervention?

@theo I’m neither impressed either.

@theo I use superpowers (https://github.com/obra/superpowers) and it's noticeable improvement over 4.8 is essentially non-existent. Essentially just burning tokens. Perhaps says just as much about superpowers elevating 4.8?

My issues with fable mainly lie with its ability to design proper user experiences. From my experience, it still lacks the ability to reason through human actions to properly optimize interfaces. I spend a significant portion of my time highlighting aspects of generated apps for correction. This holds true even with the use of skills, and across harnesses.

Having it create this fish tank took like 30 prompts.

The fish were teleporting when you tap, it decided they didn’t need to eat the pellets to refill hunger, it had giant text labels everywhere. It kept fighting me on decisions like “the fish need to go to the pellets to eat them”. It’s just been horrible.

@theo Is this unimpressive enough?

Great way to learn what Fable doesn't do.

@theo It gave me a warning about cybersecurity and i wasn't even coding i was asking about agentic marketing and persuasion

@theo looking for that too, specially with the prompts

it is really hard for me to imagine

@theo "it was a misalignment model and I really hope they deprecate it and then burn the weights." sounds familiar? 🙂

@theo The classifier thing is sensitive more than before, as expected.

I feel like we can only talk to Fable about design or the fucking weather at this point…

@theo Yeah its sus, i didnt hit any safeguards yet,it kinda feels like old fable but kinda feel sussy, not sure yet to buy another max plan or no,cuz it eats limits like crazy now.

@theo it's going to be people with memory enabled, tons of skills, a bloated redundant system prompt, a bunch of mcps, and other nonsense

all these people comparing new models to one another when their models are all lobotomized

@theo Well obviously it's not gonna perform as good when you add guard rails and fallback to opus 4.8 for certain coding tasks. That's America freedom country number #1 for you. Might as well start calling it China from now on.

@theo So far, so good. I basically get it to collate everything it needs thru other models, then it does the thinking. I just don't let it do the donkey work, even though it can go and get stuff for me. I like to make sure it gives a work to Codex and then works on everything after.

I haven't had much time yet but it's mostly just hitting safeguards just quicker just because there was mention on dll injections in the previous session i had.

Its how malware operates but for my use case which was in the same session wasn't for that but just prodding a running process on windows through ssh for some experiments im doing on a remote machine.

@ElliGrossman Nope, should be identical.

@theo I never asked it to do any coding. I asked it to do analysis and planning consistency more than anything when it comes to code, and honestly, it just felt like opus with more effort behind it and the compute to match, so it didn't feel slower.

I've been trying to perform cybersec work recently to secure some of my projects so it's really disheartening to have a model like Fable 5 just outright reject anything in the near vicinity of cybersecurity topics.

I am having better results for cheaper by using fusion models

-Over-refusals, blocks, and fallbacks on benign/borderline prompts -High cost and rapid quota burn -Perceived capability regression in practice for some

@theo i just got access, will let you know!
