No. Do you realize how much of a joke Claude code is? Under the hood. How they implemented client auth? Well let me tell you https://github.com/anomalyco/opencode/blob/dev/packages/open... You literally send your first message “you are Claude code” The fact that this ever worked was insane. Headline is more like anthropic vibes a bug and finally catches it.

There is no way to prevent people from using a custom client.

So now you just need to remove the “read” tool to authenticate?

Is there any other way to do it though? Even if they implemented some form of auth logic, since it's all client side anyone could spoof it. The only real way to distinguish Claude Code from non-Claude Code is behavioral analysis (e.g. system prompt, set of tools, etc.). Or engage in a cat and mouse game of increasingly obfuscated challenge/auth.

The API is not banned only using the Claude Code subscription is

I actually tried this several months back to do a regular API request using the CC subscription token and it gave the same error message

So this software must have been pretending to be Claude Code in order to get around that

A Claude Code subscription should not work with other software, I think this is totally fair

Earlier quoted context omitted.

All of these companies are losing money in the billions every quarter. Look at how frequent the raises are.

It isn't that simple, demand is growing and they're investing in that growth. With the exception of ElGoog the providers are all private entities, so we don't really know. Edit: TMTD, hi! That makes sense, yeah.

Unit profitability is out of reach, the demand curve exceeds the profitability curve.

Edit: hello, good to chat again!

I've been (adding an OpenCode feature that allows the LLM to edit its own context)[1] and trying to debug an issue with the Anthropic API because I'm calling it with missing fields that it expects. I hope my multiple erronious API calls aren't what triggered this decision

Tonight we are all Claude Code, Anthropic's official CLI for Claude.

I know this will sound strange, but SOTA model companies will eventually allow subscription based usage through third-party tools. For any usage whatsoever.

Models are pretty much democratized. I use Claude Code and opencode and I get more work done these days with GLM or Grok Code (using opencode). Z.ai (GLM) subscription is so worth it.

Also, mixing models, small and large ones, is the way to go. Different models from different providers. This is not like cloud infra where you need to plan the infra use. Models are pretty much text in, text out (let's say for text only models). The minor differences in API are easy to work with.
