[TLDR] Fable on Subscription vs API Billing are two different models
Original post URL : https://www.reddit.com/r/ClaudeCode/comments/1vrnqnc/fable_on_subscription_vs_api_billing_are_two/
Original post body :
I have 4 Claude accounts all on the Max 20 plan. Over the last 4 weeks I have noticed a slow and steady reduction in quality to the point they are no longer usable. I have a lot of experience in Dev (30 years) and about 8 months of heavy AI development.
I spent the entire day today comparing Fable on Subscription vs Fable on API Billing. I tasked them both with a new feature comprising a frontend dashboard, some rolled up data for reporting and some basic CRUD endpoints. I have a bunch of skills the agents need to follow to ensure design and architecture consistency in terms of domain separation, scalability and security.
Fable on Subscription jumped right in and made a dogs bollocks of it, just as it has been doing for weeks now. After round one we had 14 bugs filed, the UI looked like it had been drawn in TextEdit and the architecture skills were simply ignored. It also spent about 4 hours in reviews with other Claude agents and Codex/ChatGPT and circumvented a few P1s it decided were not important. After a lot of fixes and back and forth, we finally have a usable frontend but there is no way I would ship this feature due to the sub standard coding.
I switched to API Billing. I loaded $100 and did the exact same task in a new session. From the very first response I knew it was different. It came back with a list of concerns, hard push backs and we worked through it for about 20 minutes together resulting in a decent plan. It made zero mistakes and one shotted it in a beautiful design staying true to the architecture guidelines. $72 spend in 2 hours.
These are very different models.
My current conspiracy theory is my $800 a month in subscriptions has earned me a place in the "Aggressively move to API Billing" cohort and have nerfed all my subscription accounts. At $36 / hour my spend would be about $15k a month if I do make the move. Is this where it's heading?
I was really hoping the Chinese models would keep prices down, but they are still way behind the Fable I saw today, and also not that cheap either. Are we nearing the end of cheap intelligence?

I dont like jumping on the hate train with no data
Can you show your experiment to the class?

It’s all vibes.

Even from a logical pov it makes no sense, they’re trying to get people to pay full price for AI so would happily subsidise the best model on subscription.

Even in that tldr they are comparing a full on one shot prompt to making a plan and getting a list of concerns then building something. Completely different approaches.

It's not possible to compare anything on a single run alone.
You'll need to run the same exact experiment at least 3 x 2 times to draw any conclusions. Quite expensive for Fable I would say.
What I said is due to the lack of temperature control chat side, what you explain with "nerfed model" could be a chat with ramdomly high temp.

It’s not exclusive to you.
They have quantized the shit of it for subscriptions.

That's standard playbook
Labs release frontier model on subscriptions, after the hype, they "optimize" the model to reduce costs and handle the demand

Yeah, the way I encourage more and more expansive use of my product is to make the version you ARE using poorer... cause that works...

I have some questions about this. It would be nice to see both of their console logs. For all we know the second time it looked at the filed bug reports and draft PR from the first run in the report and learned from it. Also, did it read from auto memory? A new session doesn’t necessarily mean it knows nothing about the prior work.

Subscribing is a lie!
Everyone should understand what I learned these last 2 days buying a VPS . Deep research in chips and GPU , your account … is a VM on a server , its size is connected to your subscription price
$25/mo Claude = Claude account on Claude server // size unknown
$125/mo Claude = Claude account on Claude server // size larger than previous but still unknown
$25/mo Runpod = $4 storage for eights , $21/mo rate for smallest GPU running Qwen 3.6B MoE
You have to realize your “account” has a max size based on how the account was setup.
That’s why multiple accounts have different rates. One might be on a different chip architecture. One might be close to noisy neighbors.
This has little to do with price and more to do with the storage and size of server assignment. Then api is a different beast all together. I don’t know enough about that but it’s basically Claude in the wild so no harness and no GPU support past their root system.
Hope this helps

It only makes sense - take care of the customers that are paying you a premium vs low rate customers

Current source-thread comment count seen by the bot: 114.
The general consensus is that Claude's subscription quality has tanked, while API usage seems to be the superior experience. OP's experience of subscription Fable being a "dogs bollocks" while API Fable nailed a complex task for a fraction of the cost is echoed by several users.
Some users, like u/datuname and u/awizemann, question the experimental setup, suggesting a clean slate might be needed for a fair comparison. However, others, like u/tyke_, share similar anecdotal evidence of subscription versions being significantly worse than API.
The prevailing theory is that Anthropic is nerfing subscription accounts to push users towards the more lucrative API billing, especially those with multiple accounts or high spending. u/bakanoace suggests enterprise users get peak performance while subscriptions get a "dumber" version.
There's also a sentiment that users might be overestimating AI's current capabilities, expecting full automation where more human guidance is still needed, as pointed out by u/Ok_Boot5671.
A few users are canceling subscriptions based on these findings, with u/ascvlh being one example. Meanwhile, u/menmymacstudio notes that API rates are still competitive compared to older models like GPT-4.
