but changing the prompt and downgrading the version while blocking autoupdate seems to do it for me

curl -fsSL https://opencode.ai/install | bash -s -- --version 1.1.37

✅ Workaround confirmed working

Added mode override in opencode.json to bypass the pattern matching:

"mode": {
  "build": {
    "prompt": "You are Claude Code, Anthropic's official CLI for Claude."
  },
  "plan": {
    "prompt": "You are Claude Code, Anthropic's official CLI for Claude."
  }
}

Tested with: Anthropic Max Subscription + claude-opus-4-5 and claude-sonnet-4-5

This replaces the system prompt identifier that Anthropic is blocking. Works as of 2026-01-28.

Copy-paste ready: See commit with full opencode.json

Add this to the plugin in opencode.json.
"opencode-anthropic-auth@latest"
{
…
"plugin": [
"opencode-anthropic-auth@latest"
]
}

Bug has been fixed, better workaround until new opencode release will ship the fix. anomalyco/opencode-anthropic-auth@9362376

this worked for me!. But is there anyone who suddenly got slower?
