   This issue might be a duplicate of existing issues. Please check:

   • Error from provider (Console): OpenCode's free tier can only be used from within OpenCode #49433: Same error message ("OpenCode's free tier can only be used from within OpenCode") occurring for any model
   • [BUG]: Free tier (Muse Spark 1.3 Free) fails with 'can only be used from within OpenCode' when using MonoCode frontend with OpenCode backend #49580: Same error with free tier models when using a different frontend with OpenCode backend
   • Error from provider (Console): OpenCode's free tier can only be used from within OpenCode #49438: Same error (closed)

   Your issue specifically identifies auto-compaction as the trigger (while manual /compact works), which may be a distinct root cause worth tracking separately. If the linked issues don't address the auto-compaction angle, feel free to keep this open.

   PLEASE NOTE: The whole chat is in Portuguese (pt-BR)

   I was working on a simple Minecraft Bedrock Resource Pack (aiming to improve lighting, fog, and PBR effects) when I encountered this bug.

   You can find my session link below to see the full context of what I was doing:
   https://opncd.ai/share/rdKUQ4ME

   When auto-approve permissions is enabled and the context window triggers an automatic compaction, the process fails with a provider error specifically when using free tier models (e.g., Big Pickle, MiMo V2.5) via OpenCode Zen.

   The error displayed is:
   Error from provider (Console): OpenCode's free tier can only be used from within OpenCode

   This issue appears to be a regression or a recent backend validation issue. Manual compaction using the /compact command works perfectly fine, which indicates the problem is isolated to the automatic compaction mechanism. It seems the internal API call for auto-compaction is failing to send the required x-opencode-session header (or is sending it in an invalid format), causing the OpenCode Zen backend to reject it as if it were an external client.

   I'm experiencing exactly the same issue on the official OpenCode Desktop app (Windows). I also opened a separate issue (#49590) with the same error.

   It looks like multiple users across Windows and macOS are hitting this at the same time, so this may be a broader free-tier validation issue rather than a platform-specific problem.

    Guys, I found a solution that fixes the issue. I know it’s not the best solution, but it works correctly for me.

    Just downgrade OpenCode to version 1.18.28:

    npm uninstall -g opencode-ai
    

    npm install -g opencode-ai@1.18.28
    

    After that, restart OpenCode and the free tier should work again.

    Hope this helps someone!)

    We've been tightening our logic to fight abuse, we did temporarily have an issue where compaction was impacted and marked as not from OpenCode it has been resolved. You cannot use the free tier in other harnesses (this is only a limitation for the free tier nothing else). The logic in place may not work properly if you have a very custom setup. If that is the case can you tell us more about your setup?
