Forbidden, OpenCode Free Model Gateway Detect Abuse Traffic #56762
Thanks for reporting this, and sorry for the trouble. The Forbidden, OpenCode Free Model Gateway Detect Abuse Traffic error comes from the server side of the OpenCode free model gateway: its abuse detection has flagged traffic from your account or network. It isn't a bug in the OpenCode app, so we can't sort it out through GitHub issues. Only the team can look into a flagged account or network.
Please email help@anoma.ly with the details: roughly when it started, the exact error, and whether you use a VPN, proxy or shared network. A shared IP address can sometimes get flagged because of other people's traffic. If you've already emailed, the team will get to it, especially now that we've seen it here. Please keep email addresses, account information and payment details out of this public issue, and put them only in the email.

I can reproduce this in the official OpenCode Desktop app on macOS.
OS: macOS 26.7.1
OpenCode Desktop: 1.19.3 (official app at /Applications/OpenCode.app)
Provider: built-in opencode free models; the configuration has no custom opencode.ai/zen base URL
In the same desktop session, opencode/mimo-v2.6-flash-free first failed with OpenCode's free tier can only be used from within OpenCode. Download it at https://opencode.ai and keep building. The local log records this at 2026-10-18 09:21:52 UTC.
Later, a simple 你好 prompt to opencode/mimo-v2.6-flash-free failed with Forbidden, OpenCode Free Model Gateway Detect Abuse Traffic at 2026-10-18 11:30:34 UTC (19:30:34 China Standard Time).
The same latter error also appeared with longcat-2.5-preview-free, beam-free, and nemotron-3.5-super-vl-free between 11:32 and 11:34 UTC.
This suggests the free model gateway is rejecting requests from the official macOS desktop app across multiple free models. I have omitted account details, session IDs, and raw logs from this public comment. I understand that account or network flags require a private support investigation; I am sharing the pattern here because it followed the separate "only from within OpenCode" error in the same client.

Component Version/Info
opencode 1.18.18
Node.js v24.19.0
npm 11.17.0
OS Linux (WSL2) - Microsoft-standard-WSL2
Kernel 6.18.54.1
Architecture x86_64
Working Directory /mnt/f/wsl/prj/dummy
Configuration:
Config file: ~/.config/opencode/opencode.json (only server port 8192 configured)
Auth: OpenRouter API key configured in ~/.local/share/opencode/auth.json
Free models tested:
mimo-v2.6-flash-free (opencode provider) ❌
nemotron-3.5-lightning-free (opencode provider) ❌
nvidia/nemotron-3-ultra-550b-a55b:free (openrouter provider) ✅ WORKS
Observed Behavior:
1.Triggers on first "hello" message - no complex context, single word input
2.Multiple free models fail - both mimo-v2.6-flash-free and nemotron-3.5-lightning-free return identical error
3.Same model via OpenRouter works - nvidia/nemotron-3-ultra-550b-a55b:free through OpenRouter provider succeeds
4.Error occurs at stream phase - after "llm runtime selected" log, immediate "stream error"

Additional Context:
No proxy/VPN used
First request in new session each time
Error is consistent across multiple sessions and model switches
OpenRouter provider with same model family works correctly
Expected: Free models via opencode provider should respond to simple requests
Actual: Immediate "Detect Abuse Traffic" 403 error on first message
same issue but with message "OpenCode's free models aren't available from your current network because we've detected abusive traffic from this IP address. This isn't related to your account. If you're on a VPN or proxy, turn it off and try again, or subscribe to OpenCode Go at https://opencode.ai/go to keep building."
Closing this now, since account and gateway issues like the Free Model Gateway Detect Abuse Traffic block are handled by email, not through GitHub issues. If this is still happening, please email help@anoma.ly with when it started, the exact error, and whether you're on a VPN, proxy or shared network. Please keep account details out of this public issue and put them only in the email. Thanks for your understanding, @noureldinemam1.
Same here since 2026-10-18 ~09:13 UTC. Home network in Italy, no VPN or proxy, official OpenCode Desktop 2.0.32 on Windows 11, no automation or opencode run scripts. The block also survived an IPv6 address change, so it seems to cover the whole network prefix. Works on a mobile hotspot. I emailed help@anoma.ly on 2026-10-18 and haven't received a reply yet. Is there an expected expiry for these blocks, or another way to request a review?
