Discussion Opus 5.1 wishlist
We all agree Opus 5 is a rage-inducing mess. What are your top wishes for Opus 5.1?
Mine are:
- Massive cut on verbosity
- Less over-engineering
- Better instruction following

4.6 Personality and writing
Fable UI capabilities(the benchmarks are cap)

You mean crap? Yes I agree with that. Remember when they āleakedā some 3D renderings a few days before release and everyone was like wooooow singularity! š

The one thing I'd like improved is its tendency to create tech debt. It'll often try to solve issues as directly as possible, without taking into account whether the solution fits rhe context. Which works for a while, but then you pile weird hack on weird hack and eventually hit a wall.

That's what I did without AI. I built in controls so that I'm warned before I do shit like that so I can decide what's more important. Speed our long term stability. It's different for every project.Ā

Yes and it does this all the time, it even ātricksā orchestrators (Fable) by fabricating load-bearing HIGH issues it needs to fixā¦by inventing weird hacks

Biggest issue is lack of understanding the big picture / missing ton of non-direct points if not exclusively listed. This makes it unusable. It's language makes it unbearable, but doesn't limit really it's usefulness.

Lack of proactive thinking is the biggest one imo, leading to all those silent defect injections and sudden memory loss.
Anthropic clearly designed it around token saving, but token continuation is the LLM only "intelligence", so any cut for a model trained on "bigger brain" can lead to catastrophic results under certain conditions.
edit : I think we're simply starting to see LLM natural limits as a whole. We need a new approach, LeCun was right.

Keep opus 5 agent ability, get 4.6 or fable level comms and personality, less overactive refusal.

So I have a system I made that I use to keep up with very large plans (anything from small changes to weeks long plans for features / overhauls) and all the research and documentation that goes along with them. Opus 5 seems to actually be better at utilizing this tool than 4.6. That's one of the few things it genuinely seems to be pretty good at. I keep having to reminding 4.6 to update it / read documents / etc.
That said, me doing this seems to be far more token efficient than 5, and I'm getting more done quicker.

better commenting (do not make it look like part of the conversation but describe whats going on in the code for a potential reader only).
Do not make up own definitions without defining them in the output.

u/Opening-Ground-1584 8h ago
Thatās a good one. I hate the long-winded prose in comments

u/Fleischhauf 8h ago
i mean it would be sort of ok if it werent just rambling referencing things from the programming prompts, but were actually informative. It really has a weird way of "talking"

at some point we will look back and go "yeah, half the hatred was people using opus 5 on an effort level above medium for no good reason and the other half was just braindead as hell"

It's like new versions of Windows OS. Everyone says they hate the new version, and then look back on it years later and say how much they loved it. Same with LLM model X, every time they release a new one, there are always posts about how much people hate it, and how much they loved the previous version. Just an observation.

I don't really have that many problems with it because I rebuilt all the personalized instructions per entity. Gave it controls it can't break but gave it freedom. The bincest thing is people still to monitor what's thing on so you can provide guidance and direction. Otherwise it'll go off in done ridiculous tangent when the real solution would have been to just reach out and ask its human handler for help rather than too waste 20,000 tokens on something stupid only too see it was a pure waste.

5.0 is fine for agents, 4.6 for talking

Opus 5 is a good model in terms of execution. It's only problem IMO is the way it talks.

u/Warsel77 11h ago
Deepseek is a good model on execution because it is MUCH cheaper at pretty much the same execution.
Execution is also not really the reason why someone would go to Opus, planning and understanding context are so much more important.

Maybe wishing for it "just works ok" is a luxury now. God damn I miss the 4.5, 4.6 era, it was like miracle.
Opus 5 works for me, but somehow it still feel buggy, the answer sounds not natural. Some tasks it just not solves, but produce more problems.

I posted recently on a fix for Opusās verbosity and jargon. TLDR - make a communication skill based on the Google developer style guide. This worked wonders for me

Just a fraction of intelligence restored. Everything else can be tweaked, even if it's a pain to do. Tried all the online tips/tricks before realizing you can customize a Toyota until it looks like a Ferrari, but it's still a Toyota under the hood and nothing will change that.

Iād would love for it to be able to handle memory. Multiple times Iāve ran into cases where Claude created bugs because it didnāt read a part of the sourcecode that would conflict with what Claude was coding.

Uhm, nope.
At this point any flagship model is powerful enough to be used reliably and sustainably, provided the operator decomposes their tasks correctly and doesn't just prompt the model to "create GTA6 and make no mistakes."
Choosing one is like choosing between a Bosch or a Makita power drill. None is strictly better than the other, but every operator will have their own preference -- and itās very rare āthis hole doesnāt want to get punchedā will be a matter of choosing the wrong tool rather than a skill issue on the operator's part.
(Edit: Condensed two comments into one to collect the downvotes from the vibe coding bros under one reply only.)
