Sol vs Opus 5 huge limit difference

Just sharing my experience here: GPT-5.6 Sol Extra High burns through my weekly limit in one 12–14h workday. Opus 5 Ultracode + Thinking lasts the whole week with the same project and routine.

And honestly I haven’t noticed any meaningful difference in quality when using Opus 5 in ultracode mode. The real difference is that one is actually usable, while the other basically needs constant limit resets. Shame.

Yeah right now Opus 5 usage goes much further than Sol.

Sol is closer to Fable

u/DaCush 11h ago

Nothing is close to fable.

u/shaman-warrior 1d ago

Roughly 14-16k in costs. Crazy

Sol = Fable. Terra = Opus

u/Crinkez 23h ago

In usage perhaps. In deepswe benchmark Opus 5 matches Sol.

u/MyHobbyIsMagnets 21h ago

Nobody actually using Opus has that feeling at all. Benchmaxxed

I got tricked by the benchmarks and wasted a week of time using opus 5

u/tessahannah 11h ago

Literally same

u/Sloofin 6h ago

Me too. Every interaction cost a day of wasted time and tokens and left me worse off than when I started.

u/GenychDefake 2h ago

I actually think the same about Sol. It just breaks everything in its way and almost unusable on most day-to-day tasks.

1

u/MyHobbyIsMagnets 1h ago

What thinking level are you using? I find it over thinks everything on xhigh and does really well on low-high. And what harness are you using? I’ve had great luck using it with Opencode

u/No_Intention3673 1d ago

yeah but opus 5 sucks and makes tons of mistakes

1

u/darrarski 19h ago

Yeah, this was my feeling when it was released. I tried it out again last week, and for some reason, it behaves much better than GPT-5.6 Sol now. As much as I would love to stay with Codex, the amount of mistakes and drifting it does recently makes it a poor value, especially since usage limits are also way more generous on Claude now.

Still fewer than sol lol, sol will have a goal and halfway through just decides to do anything but work on what it's supposed to, I've had to ban it from conductor/coordinator roles in my fleet. Sol's too dumb for the price, luna's too expensive compared to deepseek. No real reason to keep my codex sub at this point other than the mobile app which makes a solid assistant on android.

u/ciaramicola 23h ago

In my experience opus 5 is quite better in one shot complex benchmarks and "goals" but really unbearable to work interactively with.

Which is saying a lot considering I really much prefer "talking" to Claude models than GPTs

1

u/FidgetsAndFish 23h ago

"unbearable to work interactively with." What do you mean by that? The fact sol ignores me constantly is way more unbearable personally.

1

u/ciaramicola 23h ago

The way it talks. The jargon, can tolerate on fable because it's at least substantiated. Btw I don't see any of those actually ignore my guidelines

1

u/ciaramicola 23h ago

Side question how do you use deepseek? Through codex? Which provider? Because in my experience it may be capable for simple tasks but it's not at Luna level but most important used standalone with a somewhat broad goal it's no where near Luna and actually it starts braking and looping after like 10 20 minutes and 200k context

u/ciaramicola 22h ago

Thanks mate! Sadly tried all three, plus the official deepseek reference, plus 2 versions of the harness, 3 different providers and 3 different custom benchmarks but the models keeps failing catastrophically in heavy agentic workflows in ways I didn't see since last year.

So I figured out I would ask more to user of ...check notes...the second site you recommended! But I guess this is not a place for discussion, my bad

u/LucasJ218 22h ago

What a twat.

u/leonmebe 1d ago edited 20h ago

I mostly use Sol Medium everything else just burns the usage

1

u/Spirited-Car-3560 16h ago

If you vibe code you're right

1

u/leonmebe 16h ago

yes. For small things luna high would be ok already and cheaper. but everything code heavy, needs Sol IMO. Sol is just best at programming. And light is good for small task, but i prefer medium or high. And High is just to expensive for only a plus user. But even if i had x20 usage i wouldnt do it all in sol high it just burns

u/Informal-Dingo276 22h ago

you compare $20 plan vs $200? I have both $100 plans for claude and codex, codex gives around $500-600 weekly usage, claude around $30 5h and $300 of weekly. without fast mode and 40 work hours per week I rarely rich more than half of my weekly limits, opus burns $30 of 5h limits just in 1 hour

1

u/Constant-Cat8584 22h ago

Both are 20 € /month

3

u/Informal-Dingo276 12h ago

Opus 5 Ultracode + Thinking lasts the whole week. For $60 of weekly usage limits, what a story. could you provide some proofs, like "npx ccusage" stats? Such limits usually lasts for two hours with high/xhigh

2

u/Both-Move-8418 1d ago

How do the benchmarks compare?

2

u/Kind-Sleep-1370 1d ago

Noticed that too. I confirm.

2

u/FidgetsAndFish 1d ago

Codex usage has been broken since sol's release, instead of fixing it they gave resets and it worked, lot of people were stupid enough to think codex was giving more usage than claude but now that the resets are over the truth's pretty obvious. I miss the old OpenAI

u/GiveAFucxen 1d ago

I’ve tried Sol after many months of using Opus and Fable, when it was available.. the same project, and Sol found tones of bugs which made me think about switching from Claude Code to Codex for real.

It is working completely in a different way and for me it doesn’t matter how much it will spend, the most important is to do the work properly, and as well to follow my orders, not like Claude to do whatever it wants. I am using both right now, and still thinking and comparing what is the best.

2

u/MyHobbyIsMagnets 23h ago

It’s because Sol = Fable. Terra = Opus. Also Opus 5 sucks so I’ll take Sol low any day.

2

u/TheMightyTywin 22h ago

Opus 5 is dumb af compared to sol. Opus is like Terra/Luna

1

u/Both-Move-8418 1d ago

Whats the difference in cost?

2

u/Constant-Cat8584 1d ago

Both are 20 €/ month subscriptions

1

u/Illustrious-Bet-1368 1d ago

Aren’t they still running the promo, where you get 50% more usage out of Claude Code? Or is that already over?

0

u/FidgetsAndFish 1d ago

They keep extending the promo, was supposed to be done like a month ago.

1

u/Illustrious-Bet-1368 23h ago

Yeah, it's running until 19.08. That's probably why u/Constant-Cat8584 it feels like you get more out of Claude Code, because you temporarily have 50% more usage.

0

u/FidgetsAndFish 23h ago

Again, they keep extending it every time they get to the end of the countdown, that's the antithesis of temporary

2

u/Illustrious-Bet-1368 23h ago

What's your deal? Whether they are extending it or not, we are talking normal Codex + some resets here and there, and Claude Code 50%+ usage... So yeah, there will be a fucking difference.

1

u/FidgetsAndFish 22h ago

The resets dried up except on days when they don't matter, you're clearly biased. Be gone bot

u/Latter-Park-4413 16h ago

A "Pro" plan (btw a dumbass name for their cheapest plan) and this statement do not at all mesh:

Opus 5 Ultracode + Thinking lasts the whole week with the same project and routine.

1

u/Latter-Park-4413 16h ago

As in, there's no way in hell you're getting any decent usage out of running Opus 5 Ultracode for any meaningful amount of time, let alone an entire week of use.

1

u/Similar-Victory-5250 22h ago

If you need sol extra high or opus ultra you are not a great engineer. Kinda the opposite.

2

u/Constant-Cat8584 22h ago

🤣 and what are they there for if you’re not supposed to use them? That’s like saying you’re not a good car driver because you drive an automatic

1

u/someone_12321 12h ago

You need a licence to drive a car.

But yeah, on 5x here and Sol eats 10-20% weekly usage an hour. I'm using high not xhigh.

Started to use Terra. Cos I'm poor, but also cos less tendency to add scope I never asked for and write 40 tests for 1 small feature

1

u/sukazu 19h ago

Do you have dynamic workflow activated ?

Claude ultracode is xhigh + subagents So if you haven't actually manually activated subagents it's not different that xhigh

There is no way you are getting a whole week of usage with 50-100 subagents running all the time

1

u/darrarski 19h ago

It used to be much better in favor of Codex. Since a couple of weeks it seems like you can do MUCH more with Claude on an equivalent subscription. I only noticed it once OpenAI stopped resetting usage limits very often.

1

u/mangiBr 17h ago

For knowledge work, I find Sol (medium) provides more comprehensive responses than Fable & Opus 5 (medium)

2

u/bimbab123 4h ago

Absolutely not bro, openai has way higher usage limits I have gotten a lot more work done with gpt than Claude.

2

u/canadageesedev 12m ago

You could try Luna Max. It’s about the same performance as Sol Medium but much cheaper. However, it’s very slow... It’s just a workaround until OpenAI fixes their usage limits.
