Exactly as the title says. I noticed my usage limits have been higher than any Opus model has given me in the past. I remember with Opus 4.1 it started out good but then they slowly started reducing usage limits over time. I assume Anthropic wants users to thoroughly test the new model, thus why the limits are high right now. They will likely start slowly reducing it again to encourage people to pay for higher tiers.

I have the Pro tier at the moment and its been great.

The past few days I have yet to reach a limit warning using Claude Code with Sonnet. With Opus 4 I get the warning of 2 minutes of it thinking on a problem..

Reached limits rather quickly!

Context for my use case:

Started 2 separate chats selecting the same project with a knowledge base size at 14%.

On one chat, I was using Opus 4, Sonnet 4 on the other.

On both chats, I began the conversation by uploading a Google Doc with around 15000 words of text.

On the Opus 4 chat, I performed a “critique my draft” based task. I ran 3 queries before I reached limits.

Alongside, on the Sonnet 4 chat, I engaged in 2 web searches. This is when I reached the limits on the Opus 4 tab.

Hey everyone,

I recently subscribed to Claude Pro and today I used Claude Opus 4.1 to create a portfolio website. It actually generated the whole site in one go, but right after that single prompt I got locked out for about 4.5–5 hours.

So now I’m wondering:

Is this lockout/usage limit only for Opus 4.1?

Or does it apply across other models too like Sonnet 4, Opus 4, Sonnet 3.7, Opus 3, Haiku 3.5, etc.?

What are the actual daily or weekly limits?

I mainly got Pro because I want to use Claude for learning LLMs, interview prep, and practicing coding by doing projects but I’m not sure how restricted I’ll be if I keep hitting limits like this.

Anyone else run into the same issue?

Does GitHub copilot or cursor give more usage for price?

I started using CC with sonnet 4.5 and never hit any limits and did continuos development but yesterday after just using 2-3 hours of Opus 4.5 but limit hit. Now I used it for 3 hours and my current session is already at 70% then I switched to Sonnet 4.5 and its increasing at the same rate and I'm about to hit limit before 5 hours complete. How does that even make any sense?

I'm at a startup and we used to share the CC Max plan at times and never hit limit, but since Opus 4.5 release I'm hitting limits for the first time. Anyone experiencing same issue?

Edit: Looking at the API cost i'm estimating Sonnet 4.0 will have the same limits as Sonnet 3.7 and Opus will be one fifth of that. Sonnet 3.7 and 4.0 have the same API cost and Opus 4.0 is five times that. That would mean "45 messages every 5 hours" for Sonnet and nine for Opus, as they're referring to it in their help center.

Let me know if you feel like that seems realistic.

Original post:

What are they? I'm not able to find any info on that on their whole website. There's the old "45 messages every 5 hours" in the help center but that's the same as before and doesn't differentiate between Opus and Sonnet.

This feels a bit sketchy, i'm scared Opus limits will be abhorrent.

I’ve run into a problem with Claude’s new 7-day usage limits for Opus 4.1.

I’m on the Max x20 plan at $200/month — the most expensive option available. But with the new weekly caps, I can’t realistically use Opus exclusively anymore. In just one day I burned through more than 10 hours of Opus time. At this rate, in 20–30 hours total I’ll be completely cut off for the week.

I’ve heard some people mention that there might be a way to pay extra for additional quotas, but I haven’t found any option in the Claude interface. I’d happily spend another $50–$100/month just to avoid being blocked mid-week, but right now it doesn’t seem possible.

I did try mixing Sonnet + Plan for token efficiency, but in practice it slowed me down. Sonnet handled simple cases fine, but for more complex coding and refactoring tasks I always had to switch back to Opus — which ends up costing even more usage time. Opus is simply the best for planning and restructuring code before production.

So my questions: • Is there any official way to pay for more Opus quota on Claude (without going through the API, which is abusively priced for my use case)? • Or am I stuck with the weekly hard cap no matter what?

Would appreciate any clarification — not looking to downgrade to Sonnet, I really need Opus full-time.
