Models search does not show custom models unless explicit difference is specified #2877
Description
Example: I have defined GPT-5 Codex Low(gpt-5-codex-low) and GPT-5 Codex Minimal(gpt-5-codex-minimal) based on GPT-5-Codex(gpt-5-codex).
Problem: Searching custom models with gpt-5 or codex will not display Low/Minimal if the word is not specified explicitly.
Is this expected behavior?
provider field in opencode.json
"openai": {
"models": {
"gpt-5-codex-low": {
"id": "gpt-5-codex",
"name": "GPT-5 Codex Low",
"options": {
"reasoning": {
"effort": "low"
}
}
},
"gpt-5-codex-minimal": {
"id": "gpt-5-codex",
"name": "GPT-5 Codex Minimal",
"options": {
"reasoning": {
"effort": "minimal"
}
}
}
}
},output.mp4
And an offtopic question, im a little bit confused about reasoning.effort and reasoningEffort. Which one should I specify for openai/openrouter, because according to their docs it's reasoning.effort

Seems like
model.Model.IDhere is anidof base model and therefore custom models are skipped:https://github.com/sst/opencode/blob/5a507023a6f3d9f166f4696bbb6424297f6afdaf/packages/tui/internal/components/dialog/models.go#L305-L310

@geril07 doesn't seem like intended behavior Ill check it out

So we use vercel ai sdk and we need to document this better but the options come from their providers, so for openai:
