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

• gpt-5.1-codex-max is missing in the OpenRouter connector #8291: Same symptom — a GPT Codex model not appearing in OpenRouter even after running opencode models --refresh
• OpenRouter.ai provider: Not listing google/gemma-3-27b-it:free variant #10748: Same pattern — a specific OpenRouter model not listed in OpenCode
• OpenRouter Provider: GPT-5.2-Codex missing xhigh variant (only low/medium/high) #11307: Related — OpenRouter GPT-5.2-Codex missing certain variants

If your issue is distinct (e.g., the model exists on OpenRouter's API but is filtered out by OpenCode), please add more detail so maintainers can distinguish it.

I figured I'd link this here, too. It might help.

codex 5.3 only shows up for zen. but not for openrouter nor copilot.

most likely not an openrouter issue because i can use codex 5.3 with openrouter via other tools like "kilo code"

i was able to get codex 5.3 to show up for openrouter by adding the following to ~/.config/opencode/opencode.json:

    "openrouter": {
