Originally created by @geril07 on GitHub (Oct 13, 2025).

Originally assigned to: @rekram1-node on GitHub.

I defined custom OpenRouter OpenAI models with different reasoning effort levels.
However, when I select the default one and then reopen OpenCode, the selected model is usually one of the custom ones instead of the one I originally chose.

Example

"provider/openrouter/models": {
  ...
  "openai/gpt-5-mini-high": {
    "id": "openai/gpt-5-mini",
    "name": "GPT-5 Mini (High)"
  },
  "openai/gpt-5-mini-low": {
    "id": "openai/gpt-5-mini"
  }
  ...
}

model is not specified in the config.

Steps to Reproduce

  1. Define models based on an existing model (id).
  2. Open OpenCode and select the base model.
  3. Reopen OpenCode — I suppose the selected model will be one of the custom ones instead of the previously selected one.

I haven't checked if it's only TUI bug or not though

UPD: the same with agents switching from #3015. Maybe it's actually a duplicate, but i feel like they are a little different

Originally created by @geril07 on GitHub (Oct 13, 2025). Originally assigned to: @rekram1-node on GitHub. I defined custom **OpenRouter OpenAI** models with different reasoning effort levels. However, when I select the default one and then reopen **OpenCode**, the selected model is usually one of the custom ones instead of the one I originally chose. Example ```json "provider/openrouter/models": { ...

Steps to Reproduce 1. Define models based on an existing model (`id`). 2. Open OpenCode and select the base model. 3.

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

  • #3015: agents switch does not respect the custom model with id - This is very similar as it involves custom models with 'id' fields not being selected correctly when switching contexts
  • #1243: Opencode calls 'Claude 3.5 Haiku' on session start, despite selecting a custom model - This describes the exact same behavior where a custom model is selected but a different model is used on startup
  • #2877: Models search does not show custom models unless explicit difference is specified - This is from the same author and involves custom models with 'id' fields having selection issues

Feel free to ignore if none of these address your specific case.

yeah there is a fix that needs to be done for #3015 that will resolve this too

I think ill close this as a duplicate since it has the same underlying issue
