Under what law can Anthropic force OpenCode to do this? Surely it's not illegal to publish code that interacts with an API that's open for everyone to see?

They don't need any actual written law behind their actions, all they need is money. What are you gonna do, fight them in court? Good luck with that, especially against a company directly associated with the US government and Palantir.

well i guess the next github will be based out of China on Alibaba cloud

Can anyone explain what’s going on here? Using API is illegal? that can’t possibly be since we now know API is not even copyrighted (which personally I disagree with bit whatever)… so what is going on here?

I believe Anthropic is trying to block the use of their Claude code subscription by third party applications like OpenCode.

I think they’re okay with someone using their API with anything, including OpenCode.

Please someone correct me if I’m wrong.

Seems fine to me. Why do people think they are entitled to use heavily subsidized services outside of the tools it's intended to work with per terms.

Was it always clear that you're not supposed to use the Claude API this way?

Yes.

I've said it before and I'll say it again. The people mad about this feel they are entitled to the heavily subsidized usage in any context they want, not in the context explicitly allowed by the subsidizer. It's kind of like a new restaurant started handing out coupons for "90% off", wanting to attract diners to the restaurant, customers started coming in and ordering bulk meals then immediately packaging them in tup…

I must be alone in this but I don't think its heavily subsidized. I see their models as really overpriced. No way they cost that much. Could they really?

Which I'm sure people would have more sympathy for if the restaurant wasn't robbing Sysco to make their food in the first place.

This wouldn't be so bad if they didn't have such a sucky tui or ecosystem. AI is chef's kiss, tooling is bottom barrel.

Not really, GPT 5.4 is a great alternative. There's no real loss from using that over Claude Opus. And open models are quite close behind.

I’ll try 5.4 again but when I spent a couple of hours with it, I found it much weaker than Claude code + opus 4.6 for working on large projects.

Are you delegating substantial work like planning and executing refactors, or more at single-line and function-level work?

The OpenCode guys have really surprised me in the way they've reacted to Anthropic shutting down the side-loaded auth scheme. Very petty and bitter. It's clearly just a business decision from Anthropic and a rational one at that, usage subsidization to keep people on the first party product surface is practically the oldest business move in the book and is completely valid.

This is not my impression, could you explain what you're talking about?

Ever since the shutdown of the side-load they've been pretty vocally anti-anthropic on twitter. Paranoid that anthropic is going to torpedo them via some backdoor now that they own bun, insinuating that anthropic shut down the auth from a position of weakness since OpenCode is a superior product, etc.

The thing is OpenCode IS a great product, I'm not sure it's "superior", but unfortunately the way things are evolving where the model + harness pairing is so important, it does seem like they are in a similar position to Cursor (and do not have the resources to try to pivot into developing their own foundational model).

Can anyone ELI5 what is open code and why Anthropic is asking them to delete something ?

OpenCode is an agentic coding CLI, similar to Claude Code, Codex etc. It supports different LLM providers, including Claude.

It originally had support for copying over your Claude subscription token and calling the same backend APIs as Claude Code, which meant you could use OpenCode with your Claude Pro/Max plans, but Anthropic came out and said that the plans were only meant for first-party clients, and everyone else should be using per-token billing.

Now OpenCode is removing this option from their product, it seems because of legal threats from Anthropic.
