# Anthropic is making a huge mistake

Jan 15, 2026

For context, Anthropic again blocked opencode from the Claude Code API.

I wasn’t planning to try other models today, but now that’s all I’m going to be doing. I’m sure they have a massive influx of users on Claude Code since Opus 4.5, I’ve been recommending it to everyone. But this level of user hostility raises the question, is this really a company you want to rely on in your workflow?

The first volley of this was an easy workaround, so whatever. But you can make this really hard, enforce a fixed system prompt, etc…

You will not convert people back to Claude Code, you will convert people to other model providers. These actions make it clear that opencode is only the start. If you aren’t using Claude Code how they want you to, they will cut you off.
