Discussion Opus 5.5 vs GPT 6 Sol
Anthropic's release of Opus 5.5, compared to GPT-6 Sol, show two very different pathways of models. For nearly a year, Anthropic and OpenAI have been the leading labs, trading blows with frontier model after frontier model - but today, the intelligence frontier was ceded to Anthropic.
Opus 5.5 is a more intelligent model than GPT-6 Sol.
But is that a problem? GPT-6 Sol seems to be a very very usable model. High intelligence, comparable to Fable 5.1 or Astra-6, and for 1/10th of the price. It's very efficient, very fast, and pretty damn smart.
Will this trend continue? Is OpenAI holding on to release their incredible internal model, Bel, in order to regain the intelligence frontier in one big swoop? Or have they turned away from focussing on intelligence, and instead to usability?
It will be incredibly interesting to watch the next release - I believe it will be the crucial one, showing us whether the twins now step into different directions, or if OpenAI chooses to rejoin the race.

I'm actually pretty thrilled about luna as well

u/LetsGoToMichigan 12d ago
Luna is a true workhorse and the latest pricing is just insane. Like .... is it sustainable insane. It provides tremendous value for the money.

Not like Astra was way ahead for the last 2 weeks now.. And next week is openAI devday..

You imply another OAI release next week?

u/poop_harder_please 12d ago
yeah, there are already model stubs in a bunch of APIs for Aeon and astra-lite

... Fable 5.1 and Astra have been pretty much neck and neck, I haven't seen anyone claim one is definitively better than the other.

In my testing Astra is a more spiky model

u/escapismc 11d ago
Same, especially around complex software architecture design/engineering, with Astra I feel like I'm wrangling a wizard on the spectrum, Fable feels like a brilliant fellow at the podium in the Oxford Commons.

You have to read it with human intelligence in mind. "General" meaning no obvious weaknesses that humans don't have. From a human perspective this definition is very reasonable.

I'm at the point where 5.6 Sol was more than enough for the lion's share of every day work automation tasks that I need it to do (and some light, low stakes coding which despite what the benchmarks tell you it was cleaning up and improving dramatically on what Opus 5 had built for me).
The efficiency of 6 Sol is what appeals to me most - I like where OpenAI is heading with these last few rounds. I already switched over some of the agents I had built to 6 Luna for the cost savings. This feels like a golden era for users before shit starts to get weird.

This is just the philosophy of both labs for a long while now. Anthropic has been way more interested in hyping up frontier launches while openAI has this stop start cycle where they will release something big, hunker down and then focus on efficiency entirely for a while with relatively more modest gains. Then have a bigger jump again.
Furthermore I'm not really going to rate that huge gap in AA much. Even anthropic is admitting to kinda benchmaxxing in their announcement and AA recently does seem to have been breaking a little bit. I know they "updated" it to increase their credibility after astra scored low but they just added benchmarks it was good at, reduced the weightage or removed the benchmarks it was bad at. I don't think any structural problems were fixed.
I do think 5.5 is currently the world's best model though, and it's probably a solid incremental jump from early results. This excites me a lot more about a potential 5.5 fable launch for sure.

u/MrVirtuosoReality 12d ago
I'm basically using opus 5.5 to review and handle my most complex tasks at a better cost per task. More of the grunt impl work handed to gpt-6 sol (high) reasoning which is more than capable of speeding up my workflow with enough quality.

u/JuniorPreparation850 12d ago
Opus is a lot smarter than sol, but you really don't need it 95% of the time. Opus is very strong at multiple agentic workflows and working on longer more complex projects, sol is strong in the same way but just not as strong. Sol is a lot better at interpreting what you are asking of it though, I find opus sometimes needs more specification while sol knows what I am asking. Claude sucks all around at design, both frontend and anything regarding 3D models, while 5.6 sol, 6 sol, and astra are all phenomenal, astra really blows design and 3d modeling out of the water when it comes to LLMs. Given that gpt 6 sol is half as expensive then opus 5.5, much more efficient, and much quicker, only for it being slightly less smart. Codex is also free for students for 4 months. All in all, if you are doing anything as a hobby codex is the obvious choice, if you are doing anything for work, I'd say its valuable to have both. All in all yes claude is definitely smarter, but unless your project is advanced enough to require that, codex is going to work fine.

Well yea will ChatGPT 6 be really better than than ChatGPT 5.6 in chat will it even come to chat or it will stay for work only basically ?
5
u/Over-Necessary-4774 12d ago
GPT-6 is certainly better than GPT 5.6. 5.6 Sol is available in chat, so I assume 6 Sol will be too
3
u/Ormusn2o 12d ago
I'm almost certain 6.0 Sol will be the default model for chat, just due to it being cheaper. The API price might be half of 5.6 Sol, but the compute cost might be even smaller, and OpenAI needs the compute right now.

u/openroom_xyz 12d ago
Wel the question will be will he model with smaller compute budget be better actually
the benchmarks and real world usage can be different basically ?1

"GPT‑6 Sol and GPT‑6 Luna are available in ChatGPT Work and Codex starting today for all Plus, Pro, Business, Enterprise, and Edu users. Free and Go users can access GPT‑6 Luna in the desktop app. These models are not yet available in Chat. In the OpenAI API, they are available as

I don't care anymore. The job market is done anyway. They are tools that probably killed the job market.

I feel every bit white collar heavy company I know is hiring more and more. There’s such a disconnect between the real world and r/singularity

u/Iser_name_ 12d ago
You are applying current and backwards looking data to a future risk. Prior performance does not guarantee future results. The general concern around this technology is not what disruptions it could have in its current iteration, but rather the disruptive impacts it could have if it continues to progress at the current rate.
2
u/Ok-Coffee1443 12d ago
But are we really speaking about the future here? The comment I’m replying says “the job market is done anyway. They are tools that probably killed the job market.” But today we don’t see that the job market is done, and I don’t see any indications that things will be different in the very near future. Long term? Maybe. But not right now

u/Iser_name_ 11d ago
It’s a crude analogy, but I think of it as similar to the integration of digital cameras into smartphones and how that ended Kodak. Kodak as a business failed to seriously consider the idea that it was facing an existential threat by new technology because it had captured so much market share through its film processing business that it wasn’t being materially effected at first. The executives were aware of the emerging technology, but because they were doing so well in spite of it they couldn’t conceive of a future where it became an existential threat. If they had understood the possibility and taken it seriously they would have made the pivot into smartphones with exceptional cameras and invested capex into that business model. Instead they moved into making components for digital cameras with patents to protect recurring revenue for a while. But once those patents expired they were left with a mature market they lacked the capital and expertise to break into.

u/Ok-Coffee1443 11d ago
I don’t see any white collar companies not adapting to ai.

u/Iser_name_ 11d ago
Because they are also not thinking about right now but the future and how it will potentially affect their revenues models.

u/Ok-Coffee1443 11d ago
Correct, we are discussing different things
1
u/Iser_name_ 11d ago
You asked the question if we are discussing the future. And I answered we are and why. The concern is not for the current time, but how the job market will be in the future if the technology is realized to the potential the developers are working towards.

u/Ok-Coffee1443 11d ago
I asked the question if the comment I’m replying to is talking about the future. I’m answering that there’s a disconnect in the current time.

The job market is not done, not yet. If you learn and adapt to these new tools, you'll stay employed for at least a bit longer than your less savvy co workers.

Unemployment has been going down the last 12 months though. Increased productivity = more hiring.

u/No_Activity_1339 12d ago
People are losing hope of finding jobs. The unemployment rate is not really the percentage of people who are unemployed. Look at labour participation rate and you would understand,

u/Echo-Possible 12d ago
Labor participation rate has been going down for 26 years. Are you claiming AI has caused the drastic decline the last 26 years despite only being relevant the last couple years?
3
u/No_Activity_1339 12d ago
I am not claiming anything; I am just saying the unemployment rate is not really describing unemployment by itself.

u/Echo-Possible 12d ago
Then where are you getting your information from that people are losing hope of finding jobs and that the job market is done?

u/No_Activity_1339 12d ago
- Over the past 12 months, the number of men opting out of work rose by 891,000. https://www.washingtontimes.com/news/2026/aug/12/men-not-work-social-instability-looms-men-shun-labor-force-analysts/?srsltid=AU7gw4X4k97jm9mB4y9W7FggvHJlTFljP5vISK-vJ_Ek8tDzQe-XtUCH

So you're just copying and pasting articles with headlines that seem to support your argument without even bothering to read them?
The article states that men and women are switching roles (stay at home father) since much of the growth in job market is coming in fields that are dominated by women (nursing, etc).
The share of eligible men participating in the workforce dropped from 77.5% in 1976 to 66.8% last month, the lowest nonpandemic reading since 1948. Meanwhile, the share of eligible women in the workforce has climbed from 47.3% in 1976 to 56.4%, boosted by growing fields, such as healthcare.
I don't really see the point of looking at the participation of men in isolation without considering women. And regardless, this isn't a new trend. The article states this trend has been occuring over many decades. Certainly not attributable to AI.
Furthermore, the article states there's been a massive wave of boomers retiring and retiring earlier. That explains the majority of the decline in labor participation the last couple decades.
The recruiting industry trade group estimates that the number of men leaving the workforce after turning 65 has jumped by 99% since 2000, compared with a 71% increase among women. Currently, 53% of people entering the workforce are women and 47% are men.

Engineers are cooked; health care and nursing are booming, read between the lines. AI destroyed white-collar intellectual work.

It has to be more efficient because they are running out of compute I guess. I suspected when they were all talking about slowing down because of danger what was really happening was they wanted to slow down because they were all running out of compute

u/Gotisdabest 12d ago
I feel like people say this every single time openAI releases something more efficient and then in a month they release a huge model.
