It might be some confirmation bias here on my part but it feels as if companies are becoming more and more hostile to their API users. Recently Spotify basically nuked their API with zero urgency to fix it, redit has a whole convoluted npm package your obliged to use to create a bot, Facebook requires you to provide registered company and tax details even for development with some permissions. Am I just old man screa…

They put no limits on the API usage, as long as you pay. Here, they put limits on the "under-cover" use of the subscription. If they can provide a relatively cheap subscription against the direct API use, this is because they can control the stuff end-to-end, the application running on your system (Claude Code, Claude Desktop) and their systems. As you subscribe to these plans, this is the "contract", you can use onl…

I think what most people don't realize is running an agent 24/7 fully automated is burning a huge hole in their profitability. Who even knows how big it is. It could be getting it on the 8/9 figures a day for all we know.

There's this pervasive idea left over from the pre-llm days that compute is free. You want to rent your own H200x8 to run your Claude model, that's literally going to cost $24/hour. People are just not thinking like that. I have my home PC, it does this stuff I can run it 24/7 for free.

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.

Read the ToS, you are paying to use their products. If you want to use other products that integrate with the Anthropic LLMs they offer a product which is the API. You can use Opencode by connecting your API and being charged per token.

Doesn't that make sense? If you use it more you get charged more, if you use it less you get charged less.

Opus 4.6 genuinely seems worse than 4.5 was in Q4 2025 for me. I know everyone always says this and anecdote != data but this is the first time I've really felt it with a new model to the point where I still reach for the old one. I'll give GPT 5.3 codex a real try I think

I asked Codex 5.3 and Opus 4.6 to write me a macos application with a certain set of requirements. Opus 4.6 wrote me a working macos application. Codex wrote me a html + css mockup of a macos application that didn't even look like a macos application at all. Opus 4.5 was fine, but I feel that 4.6 is more often on the money on its implementations than 4.5 was. It is just slower.

Codex has written me 3 very nice mac os applications in the past week lol

Stop giving money to the company that doesn't give you what you want.

It is important that the company knows why they are losing customers, though.

Yes. You can build third party applications on top of codex app server. All open source. https://developers.openai.com/codex/app-server/

Codex app-server is the interface Codex uses to power rich clients (for example, the Codex VS Code extension). Use it when you want a deep integration inside your own product. It mentions 'Inside your own product', but not sure if that means also your own commercial application.

I think it's permissible. Zed uses it to power their Codex integration. OpenAI has been quite vocal about it.

I'm not going to say what platform but it's an agentic coding tool, I know for a fact the platform loses in the mid $200.00s on a $20.00 plan. 10:1 loss leader for customer acquisition is crazy, and they'll have to make that up in the future somehow, they're all fumbling on how to vendor lock their customers, and its not necessarily clear they're going to be able to. I expect some big falls from 10 figure businesses…

Calling LLM users "slot machine users" makes no sense and tells me that you just have an axe to grind.

True, they should be called "slop machine users" instead.

Yeah that's not how it works in practice in a datacenter with the latest GPUs, they are basically perishable goods. You don't run your gaming PC 24/7.

No, you're fundamentally wrong. There's the regular wear & tear of GPUs that all have varying levels of quality, you'll have blown capacitors (just as you do with any piece of hardware), but running in a datacenter does not damage them more. If anything, they're better taken care of and will last longer. However, since instead of having one 5090 in a computer somewhere, you have a million of them. A 1% failure rate q…

GPU bitcoin mining rigs had a high failure rate too. It was quite common to run at 80% power to keep them going longer. That's before taking into account that the more recent generations of GPUs seems to be a lot more fragile in general.

Is it? I’ve never touched Facebook api, but it sounds ridiculous that you need to provide tax details for DEVELOPMENT. Can’t they implement some kind of a sandbox with dummy data?

WhatsApp takes bot spam very very seriously, and as a result, there is zero bot spam. Before you can sign up to build a WhatsApp bot, you need to jump through a million hoops, and after that, every automated message template must be vetted by Meta before it can be sent out, apple style. I'm glad of this, because unlike SMS and other messaging platforms, WhatsApp is spam free and a pleasure to use.

WhatsApp is certainly not spam free. I get spam over WhatsApp, less than on telegram but still more than zero.

They will [try to] ban open weights for ethics / security reasons: to stop spammers, to protect children, to stop fascism, to defend minorities. Take your pick; it won't matter why, it will only matter which media case can they thrust in the spotlight first.

Yes of course they will; the CEO of Anthropic makes that argument, very openly, all the time. But it will be hard to do, I think.

Hopefully, but they'll lobby hard, supported by all the money they raised.
