Re: Anthropic blocks third-party use of Claude Code subscriptions

I feel like I'm the only person on this site that doesn't use AI for coding. I guess there's probably a lot of other people that haven't commented on this story who don't use it either. But when I read about how much hype and all that sort of stuff there is in the AI industry, and then I see the amount of posts and commentary and deep technical discussion about how this feature has affected people, I'm not so sure. E…

> I feel like I'm the only person on this site that doesn't use AI for coding.

I’m surprised by that. One reason I follow discussions here about AI and coding is that strong opinions are expressed by professionals both for and against. It seems that every thread that starts out with someone saying how AI has increased their productivity invites responses from people casting doubt on that claim, and that every post about the flaws in AI coding gets pushback from people who claim to use it to great effect.

I’m not a programmer myself, but I have been using Claude Code to vibe-code various hobby projects and I find it enormously useful and fun. In that respect, I suppose, I stand on the side of AI hype. But I also appeciate reading the many reports from skeptics here who explain how AI has failed them in more serious coding scenarios than what I do.

OpenCode brought this on themselves and their users. Plugging Claude Max subscriptions into other agents has been against the terms of service basically since the start and I imagine Anthropic must have issued plenty of warnings here that were ignored. They wouldn’t do this unless they really had to. If folks are mad about being rugged, blame OpenCode for misleading their users when they’ve long known this day was coming. Brilliant cynical strategy though to exploit soft enforcement for growth and lay the blame at the company that provided them cheap tokens.

For folks not following the drama: Anthropic's $200/month subscription for Claude Code is much cheaper than Anthropic's pay-as-you-go API. In a month of Claude Code, it's easy to use so many LLM tokens that it would have cost you more than $1,000 if you'd paid via the API. Why is Anthropic offering such favorable pricing to subscribers? I dunno. But they really want you to use the Claude Code™ CLI with that subscript…

> Anthropic shouldn't have an all-you-can-eat plan for $200 when their pay-as-you-go plan would cost more than $1,000+ for comparable usage. Their subscription plans should just sell you API credits at, like, 20% off. Sorry, I don't understand this. Either you're saying A) Everyone paying $200/mo should now pay $800/mo to match this 20% off figure you're theorizing... or B) Maybe you're implying that the $1,000+ cost…

Not the OP, but it seems pretty clear to me - they're suggesting that fixed per-month pricing with unlimited usage shouldn't exist at all, as it doesn't really make sense for a product that has per token costs.

Instead, they're saying that a 200$/month subscription should pay for something like $250 worth of pay-per-token API tokens, and additionally give preferential pricing for using up more tokens than that.

So, if the normal API pricing were 10$ per million tokens, a 200$ per month subscription should offer 25M tokens for free, and allow you to use more tokens at a 9$/1M token rate. This way, if you used 50M tokens in a month, you'd pay 445$ with a subscription, versus paying 500$ with pay-as-you-go. This is still a good discount, but doesn't create perverse incentives, as the current model does.

Anthropic want you to use claude code cli badly and are prepared to be very generous if you do. People want to take that generosity without the reciprocity. I don't normally like to come down on the side of the megabigcorp but in this case anthropic aren't being evil. Not yet anyway.

Assuming the actual price for many user is closer to 1k USD/mth than to 200 USD/mth, and the actual price is closer to their target margin to be a viable business, they're practically subsidising usage after 200 USD/mth. Together with other AI-TECH doing the same, they fabricate a false sense of "AI is capable AND affordable", which imo is evil.

Earlier quoted context omitted.

I can easily get Claude Code to run for 8-10 hours unsupervised without stopping with sub-agents entirely within Claude Code. I think it is more likely that if you stick with Claude Code, then you are more likely to stick with Opus/Sonnet, whereas if you use a third party CLI you might be more likely to mix and match or switch away entirely. It's in their interest to get you invested in their tooling.

> if you use a third party CLI you might be more likely to mix and match or switch away entirely. I really like doing this, be it with OpenCode or Copilot or Cline/RooCode/KiloCode: I do have a Cerebras Code subscription (50 USD a month for a lot of tokens but only an okayish model) whereas the rest I use by paying per-token. Monthly spend ends up being somewhere between 100-150 USD total, obviously depending on what…

I don't do this much because I really like Opus 4.5, and so far I haven't hit the limits on the $200 subscription much, but I do have some projects where I might need far higher limits.

As a matter of principle, I really would like the flexibility though, as while I love Opus now, who knows which model I will prefer next month.

The fix has been merged in https://github.com/anomalyco/opencode-anthropic-auth/pull/11 , and PR https://github.com/anomalyco/opencode/pull/7432 is open to bump the version. Until it's released, here's a workaround: 1. git clone https://github.com/anomalyco/opencode-anthropic-auth.git 2. Add to ~/.config/opencode/opencode.json: "plugin": ["file:///path/to/opencode-anthropic-auth/index.mjs"] 3. Run: OPENCODE_DISABLE_D…

Anthropic shot themselves in the foot with this decision. It‘s a PR nightmare and at the same time the open source community will always find a way. They just wasted everyone‘s time and likely lost a bunch of users while doing so. Thank you for sharing this!

The open source community won't always find a way. Remote attestation isn't a new concept (it doesn't have to be hardware backed, the concept is general).

The industry has enough experience with this by now to know how it goes, and open source projects are always the first to drop out of the race. The time taken to keep up becomes much too high to justify doing on a voluntary basis or giving away the results, so as the difficulty of bypassing checks goes up the only people who can do it become SaaS providers.

BluRay BD+ was a good example of that back in the day. AACS was breakable by open source players. Once BD+ came along the open source doom9 crowd were immediately wiped out. For a long time the only breaks came from a company in Antigua that sold a commercial ripper, which was protected from US law enforcement by a WTO decision specific to that island.

You also see this with stuff like Google YouTube/SERP scraping. There currently aren't any open source solutions that don't get rapidly blocked server side, AFAIK. Companies that know how to beat it keep their solutions secret and sell bypasses as a service.

What an incredibly entitled message. If you know what anthropic should and shouldn't do, go start your own AI company.

Engineer working on Amp here. I'm very surprised that it took them this long to crack down on it. It's been against the terms of service from the start. When I asked them back in March last year whether individuals can use the higher rate limits that come with the Claude Code subscription in other applications, that was also a no. Question is: what changed? New founding round coming up, end of fiscal year, planning f…

You think anthropic is losing money now with the weekly limits? And while hitting the gas on mass market?

This headline is misleading. EDIT: Or rather was, at it has now been edited to be accurate. You can still bring your own Anthropic API key and use Claude in OpenCode. What you can no longer do is reverse engineer undocumented Anthropic APIs and spoof being a Claude Code client to use an OAuth token from a subscription-based Anthropic account. This really sucks for people who want a thriving competitive market of open…

The ideal endgame is that AI lets us build tools that make it impossible to tell what application or device is using their APIs and everything becomes open to third party clients whether they like it or not.

That's a lot of supposition leading to a shaky conclusion.

Your speculation may be correct, of course, but I have yet to see any mention of Anthropic issuing "plenty of warnings", or only taking this action because they "really had to."
