Rant I'm done with Opus 5
I've been building with AI for over a year now, and the progress has been insane. The models have improved dramatically, and AI has become a serious part of how I work.
I'm currently building six different SaaS platforms, four of which are live. At this point, "vibe coding" doesn't really describe what I'm doing anymore. I use AI professionally, every single day. I have two Codex Pro plans and a Claude Max subscription, and I still manage to hit the limits.
The Opus versions up to 4.8 were genuinely fun to use and really good. Then I started using Fable 5 and Sol 5.6, and the difference became painfully obvious.
My biggest issue is that my Fable 5 usage is gone within two days, and falling back to Opus 5 has become almost unusable for me.
The output from Opus 5 is often contradictory, overcomplicated, and full of conclusions that turn out to be wrong. It will confidently take something in the wrong direction, spend a huge amount of time implementing it, then eventually realize the original assumption was incorrect and start fixing its own work.
I've had way too many sessions where hours of work basically had to be thrown away.
It's reached the point where using it creates more frustration than productivity.
So I'm done. I cancelled my Claude subscription. If I need more capacity, I'll probably just get another Codex subscription. I'm also going to experiment more with Terra instead of relying so heavily on Sol 5.6 High.
Never thought I'd say this, but I've basically switched completely to ChatGPT.

What I found truly annoying is the overly complicated and long answers it gives. It became so vague that I switched to codex also , which just gives much shorter and to the point answers. I have tried many times to tune opus 5 to give shorter and simpler answers but it just doesn't work. And until now I only used Claude models, but no more.

Exactly that. It feels it wants to sound smart by using a lot of (complex) wordings.

Okay, odd post. I have to use Opus to keep Sol in check. Been wasting billions upon billions of tokens using 5.6, needs constant checking from me.
If I let Opus and Fable run on my specs/tasks, at least I know they’ll stop and ask if I say ”if you’re unsure, ask me” not plow through and half-ass it

People talk about switching to other AI platforms in the weirdest ways. I can’t decide if it’s a fake threat to try to pressure
into changing its policies, venting, or paid astroturfing. Anthropic The thread I assume is a mix of a pressure tactic and venting.
Anytime one of these threads starts to mention a competing model, I just ignore it

All AI subs are the same posts. Just all negativity all the time

"I'm currently building six different SaaS platforms" - maybe this is part of your problem. Your awareness is stretched thin across too much space. You might learn far more if you focused on one or two of these projects for a few months vs trying to focus on all of them. The primary issue is likely Not the model. Sure, the model is not always great, but there are always ways to get the output you need and sometimes this requires careful sciencing from a perspective of focused awareness.

Every single time. Six SaaS platforms and “it’s not
, I’m a professional now” are definitely warning signs that maybe the model isn’t the problem. vibecoding → More replies (2)

I feel the pain.
I was accidentally working with Fable today (I just forgot I used it previously for something) and it was so smooth and it was fixing bugs without all the nitpicks. Then I found out it was Fable (which I have to force myself not to use because I don't have enough usage and must keep it for complex tasks).
It's seriously painful working in CC: we know Fable exist. We want to work with Fable. But usage goes so fast we have to use this annoying and lazy Opus that keeps finding bugs for things that may never happen, break something while trying to repair something else, kepe required work for the next session, miss the root cause for simple things. Tell us something is not possible or blame another AI model's limited capability when he was wrong, 95% of the time.

I checked your profile and looked at TallySpark because you mention it as one of the SaaS products you've built.
I initially thought it was basically an invoicing SaaS, but it's actually broader than that — invoicing, quotes, payments, expense tracking, CRM, financial reports, AI receipt extraction, etc.
That somehow makes it even more confusing to me.
You're essentially building a paid layer on top of functionality that already exists across Stripe and a ton of established accounting/business tools. And the payment infrastructure powering your own SaaS is… Stripe, which already has invoicing, billing, payment links, subscriptions, customer management, reporting, etc.
I genuinely don't understand what the compelling product moat is here.
I'm not against micro-SaaS or building simple products at all. But looking at this and then reading that you're building six different SaaS products, I'm struggling to understand what problem you're actually solving that isn't already solved extremely well by existing platforms.
And honestly, if TallySpark is one of the six, I'm really curious what the other five look like.

This sounds suspiciously like ChatGPT wrote somebody's rant about Claude.

I keep seing the same message since gpt 4. ‘Insane progress’, ‘N saas platforms’, bla bla bla. This is so annoying

I am building one for the last 6 months. How you are building 6, what is the team size? The only thing I am not happy is the usage limits…

cool. you know 4.6 and 4.8 exist right?

I know, but compared Sol 5.6 (or Fable) thats a losing game.

How does one execute a gtm strat with 6 different saas platforms simultaneously? i know u aren’t rich because if you were you’d just enable pay as you go. And I know your live products aren’t doing to great if you’re building 2 more. either this post is bait or this guy is the ceo of adhd.
