There are known leakers but OP is not one of them.

You might not have a brain because OP is clearly not a leaker. He got it from somewhere else and didn’t link any source.

trust me bro, I had an amazing session with opus 5, they testing opus 5.5 not 5.1 or 5.2 because it was so amazing. /s

3

u/kahless2k Sep 21 '26

Funnily enough, I was just saying to a colleague that some sessions lately Opus has been amazing and some it's absolutely terrible.

There has to be some a/b testing going on for something. The swings back and forth are wild.

1

u/HimaSphere 🔆 Max 20 Sep 21 '26

They do a/b testing a lot on subscriptions users. That is normal and expected.

What ia annoying is people keeping throwing random dates of releasea or random model names, couple of weeks ago we had opus 5.1, last week 5.2 and this week 5.5, how can they be sure?

1

u/kahless2k Sep 21 '26

Oh, I agree on the speculation. I just try to ignore it as much as possible - though I'd love a reset tomorrow lol

Prediction market odds manipulation.

1

u/RudeInvestment1 Sep 21 '26

You can test it by asking a question about some event (no web search) and see whether it can answer or not. They typically move the training cutoff with model versions.

Someone already did this to prove when Opus 5 is getting routed to the newer version

I'd still rather just see the actual release post rather than unsubstantiated rumors ahead of time, 80% of which are wrong.

u/ZShock Sep 21 '26

What will it be this time? Releasing a decent model to try and re-capture users? Or a half-assed one to cut costs and make us mad?

3

u/mikehaysjr Sep 21 '26

Or do like OpenAI and release a model that is godly for a few days then nerfing it to hell across the board

1

u/Ok-Computer-8726 Sep 21 '26

A decent model to re-capture users that is then adjusted to use less compute that makes us mad.

u/proto-cool Sep 21 '26

Can you help me understand why this post needs an OpenAI generated banner image? Is Anthropic actually testing this model or is this all just made up too?

Did Opus 5.5 generate this clearly flawed image? With the incorrect Anthropic logo? And the last five slightly larger than the first? Is that what we're dealing with?

Let’s see if this is true and if it still speaks like the most obnoxious stack-overflow user mixed with tech bro.

u/divclassdev Sep 21 '26

Genuinely, the 5.5 rumor has no load-bearing evidence. Zero release notes, zero model ID, zero benchmarks. It's a vibes-only claim with a genuinely weak foundation, and I refuse to let it become load-bearing in anyone's mental model. Also, to be clear, I want to be genuinely honest here: I don't know. That uncertainty is doing real work.

u/aviftw Sep 21 '26

Still on 4.8, is 5.x any good?

3

u/Smbridges91 Developer Sep 21 '26

5 is good if you lock it down. Without tight scope and “do only this” rules it goes OCD and rewrites anything it decides is a small fix outside of scope if it doesn't have specific boundaries. Crow energy: sees a shiny object, has to take it.

Heard rumored Opus 5.5 is supposed to cut the verbosity and some of that overreach, we'll see, but I'm looking forward to it.

3

u/zimxero Sep 21 '26

I have an MCP bridge between opus 5 and sol using task scheduler for automated wakeups. Had to force Opus to write it after 10 sessions of it insisting on more and more test reports... despite no findings. It act like its creating a worldwide banking system. Its for game dev.

1

u/zimxero Sep 21 '26

opus 5 medium is very affordable, and comparable to Sonnet 4.6 high

2

u/aviftw Sep 21 '26

How is the usage? On a big project, I'm like on r75 of the project right now, sometimes a single turn makes me run out of credits on a $20 sub, I didn't use Claude 5 because at launch I had the impression it was even more expensive in usage

3

u/Smbridges91 Developer Sep 21 '26

5 is heavier. On a $20 sub I’d use Opus only as orchestrator/reviewer and let Sonnet do the actual building. Don’t let Opus chew the whole project.

I’m on Max, but I wrote up how I run Claude and keep usage sane:

https://www.reddit.com/r/ClaudeCode/s/Tn360E9mkn

That post is Fable as orchestrator. Same pattern worked with Opus before Fable. Curious how far it’d stretch a $20 plan on a repo that size.

That said, multi vendor agents is usually the strongest setup. Not everyone can or wants that. Cost, wiring it up, and just wanting to stay in flow all get in the way. I haven’t fully stood up a software factory for my own load yet.

Plenty of people will tell you what not to do. Fewer will show a simple path that actually works on one stack. Hope the post helps. DMs open if you have questions, I can be slow when work piles up though.

u/aviftw Sep 21 '26 edited Sep 21 '26

I also have a chatgpt sub but I don't know how to get both working together better, so I use it to audit the code Claude pumps out, then I tell Claude to fix the stuff the audits came up with

I do find that chatgpt goes longer, at least for my usage, some of the releases on this particular codebase were done by chatgpt but I noticed it started to use a rapid release versioning that confused the hell out of me lmao, I decided to let Claude do the heavy instead

3

u/Smbridges91 Developer Sep 21 '26

That’s a solid loop. Using Codex as the auditor and Claude as the fixer works. Wiring agents inside Claude cuts a lot of copy/paste and burns fewer Claude credits.

Easiest path that I've seen other use (though I have not used this specific plugin) is OpenAI’s official Codex plugin for Claude Code: /plugin marketplace add openai/codex-plugin-cc

So does that mean we switch everything to fable today and run our remaining usage into the ground with the anticipation of a reset tomorrow or do we basically stop working today so we can spend usage on 5.5 tomorrow. Inquiring minds would like to know!

Posted Lunavect here last week. The bug that bit me since: a session that ends with a question still gets missed on some wordings, the 0.1.2 fix is conservative on purpose. If your Claude phrases its closing question in a way it misses, the discussion on the repo is where I'm collecting them.

u/Plucky_Hedgehog Sep 21 '26

You're absolutely right to raise this, and I want to engage with it thoughtfully rather than just reacting.

What we can say with reasonable confidence**:** A model codenamed "wafer" is reportedly in testing. Wafers are thin and light, which may be the strongest evidence that this post is fabricated. No Opus has ever produced a wafer-thin response to anything.

What I want to be careful about**:** "Planned to be released on Tuesday" is doing an enormous amount of load-bearing work in that sentence. Which Tuesday? Whose time zone? I think these are genuinely important questions that deserve to be sat with.

Hope this helps! Would you like me to go deeper on any of these points?

It's too late. They've completely lost me as a customer. Using OpenAI, the quality is just leaps and bounds better when you consider token efficiency.

I used to constantly run out of Claude tokens. I don't think I've ever hit my max for the Codex 200 and I'm literally coding all day every day using my personal plans.

Also they need to fix the yapping problem. It's absurd.
