As things are currently, better models mean bigger models that take more storage+RAM+CPU, or just spend more time processing a request. All this translates to higher costs, and may be mitigated by particular configs triggered by knowledge that a given client, providing particular guarantees, is on the other side.

That’s not how Claude Code works. It’s not like a web chatbot with a layer that routes based on complexity of request.

You don't control what happens when a request hits their endpoint though.

Anthropic is going to be on the losing side with this. Models are too fungible, it's really about vibes, and Claude Code is far too fat and opinionated. Ironically, they're holding back innovation, and it's burning the loyalty the model team is earning.

I thought Anthropic would fall after OpenAI, but they just might be racing to the bottom faster here.

Maybe for coding but the number of normie users flooding to Claude over OAI is huge.

This is honestly the key difference here. I’m morally okay with using Claude Max Whatever with something like OpenCode because it’s literally the same thing from the usage pattern perspective. Plugging Nanoclaw into it is a whole another thing.

It probably doesn't help that the creator of OpenClaw just got hired by Anthropic's competitor. This sounds like engineering, finance, and legal got together and decided they were in an untenable position if OpenAI started nudging OpenClaw to burn even more tokens on Anthropic (or just never optimize) + continually updated workarounds to using subscription auth. But I'm sure OpenAI would never do something like that.…

> OpenAI started nudging OpenClaw to burn even more tokens on Anthropic

Not possible: OpenClaw is run by a foundation, and is open source, which means OpenAI has no leverage to do such a thing.

https://mariozechner.at/posts/2025-11-30-pi-coding-agent/ This coding agent is minimal, and it completely changed how I used models and Claude's cli now feels like extremely slow bloat. I'd not be surprised if you're right in that this is companies / management will prefer to "pay for a complete package" approach for a long while, but power-users should not care for the model providers. I have like 100 lines of code…

> I'd not be surprised if you're right in that this is companies / management will prefer to "pay for a complete package" approach for a long while I mean I suspect for corporate usage Microsoft already has this wrapped up with Microsoft & GitHub Co-Pilots.

OpenAI, Anthropic, Google, Microsoft certainly desire path dependence but the very nature of LLMs and intelligence itself might make that hard unless they can develop models which truly are differentiated (and better) from the rest. The Chinese open source models catching up make me suspect that won't happen. The models will just be a commodity. There is a countdown clock for when we can get Opus 4.6+ level models and its measured in months.

The reason these LLM tools being good is they can "just do stuff." Anthropic bans third party subscription auth? I'll just have my other tool use Claude Code in tmux. If third party agents can be banned from doing stuff (some advanced always on spyware or whatever), then a large chunk of the promise of AI is dead.

Amp just announced today they are dumping IDE integration. Models seem to run better on bare-bones software like Pi, and you can add or remove stuff on the fly because the whole things open source. The software writes itself. Is Microsoft just trying to cram a whole new paradigm in to an old package? Kind of like a computer printer. It will be a big business, but it isn't the future.

At scale, the end provider ultimately has to serve the inference -- they need the hardware, data centers & the electricity to power those data centers. Someone like Microsoft can also provide a SLA and price such appropriately. I'll avoid a $200/month customer acquisition cost rant, but one user, running a bunch of sub agents, can spend a ton of money. If you don't own a business or funding source, the way state of the art LLMs are being used today is totally uneconomical (easy $200+ an hour at API prices.)

36+ months out, if they overbuild the data centers and the revenue doesn't come in like OpenAI & Anthropic are forecasting, there will be a glut of hardware. If that's the case I'd expect local model usage will scale up too and it will get more difficult for enterprise providers.

(Nothing is certain but some things have become a bit more obvious than they were 6 months ago.)

Reading these comments aren't we missing the obvious? Claude Code is a lock in, where Anthropic takes all the value. If the frontend and API are decoupled, they are one benchmark away from losing half their users. Some other motivations: they want to capture the value. Even if it's unprofitable they can expect it to become vastly profitable as inference cost drops, efficiency improves, competitors die out etc. Or wor…

the fat and opinionated has always been true for them (especially compared to openai), and to all appearances remains a feature rather than a bug. i can’t say the approach makes my heart sing, personally, but it absolutely has augured tremendous success among thought workers / the intelligensia

Do you not understand that they run the regular subscription at a huge loss? In exchange they require you to stick with Claude Code. You are free to use the API.

Why can't they run the API at a huge loss too then??

Because if you do everything at a huge loss, you run out of runway very quickly.

I don't see how it's fair. If I'm paying for usage, and I'm using it, why should Anthropic have a say on which client I use? I pay them $100 a month and now for some reason I can't use OpenCode? Fuck that.

You're touching on the eternal App Store debate. "It's my phone, I should be able to install whatever I want on it!" Which is true, but also hasn't been true since the mid-90s (early 2000s at the latest).

Not quite though. You can install Claude's apps wherever they're supported, and maybe even fiddle with the source code (I'm unsure). And you can use any other coding apps that you want. The only real restriction is how those apps are allowed to connect to the providers' services, which are running on their servers, etc. There's a movement from "my local domain" to "their remote domain", and they're allowed to have full control of theirs as you - would prefer, I think - full control of yours.

That’s kind of the point. Even if users can choose which model to use (and apparently the default is the largest one), they could still say (For roughly the same cost): your Opus quota is X, your Haiku quota is Y, go ham. We’ll throttle you when you hit the limit.

Of course it was.

  - It was possible to do it.
  - OpenCode did not break any security protocol in order to integrate with them. 
  - OAuth is *precisely* a system to let third-party applications use their resources.

It's not what they wanted, but it's not my problem. The fact that I was a customer does not mean that I need to protective of their profits.

So what?!

Basically, they set up an strategy they thought it was going to work in their favor (offer a subsidized service to try to lock in customers), someone else found a way to turn things around and you believe that we should be okay with this?!

Honestly, I do not understand why so many people here think it is fine to let these huge corporations run the same exploitation playbook over and over again. Basically they set up a mouse trap full of cheese and now that the mice found a way to enjoy the cheese without getting their necks broken, they are crying about it?
