/model TUI picker does not display all custom provider models (models load correctly but don't appear in UI)

[MasuRii]

Description

Custom models defined in opencode.jsonc under custom providers are correctly loaded by OpenCode (verified via opencode models --verbose), but many of them do not appear in the /model TUI picker dialog.

Key observation: Models that have been used recently appear in the "Recent" section, proving they are functional. However, when scrolling through the provider sections in the picker, many models are missing from the list.

Evidence

Models loaded (via opencode models): 23 models across 3 providers
Models visible in /model picker: ~15 models (varies based on Recent section)

Provider	Models in Config	Models in /model Picker	Missing
aistudio (custom)	7	2 (+ some in Recent)	5
myproxy (custom)	12	~8	~4
opencode (built-in)	4	4	0

Example missing models:

• aistudio/gemini-2.5-pro - loads correctly, not in picker
• aistudio/gemini-3-pro-preview - loads correctly, not in picker
• myproxy/antigravity/claude-opus-4-5 - loads correctly, not in picker

OpenCode version

1.0.201

Steps to reproduce

1. Create a custom provider in opencode.jsonc with multiple models:

{
  "provider": {
    "myproxy": {
      "npm": "@ai-sdk/openai-compatible",
      "name": "My Custom Proxy",
      "options": {
        "baseURL": "http://127.0.0.1:8000/v1"
      },
      "models": {
        "model-a": { "name": "Model A", "limit": { "context": 100000, "output": 8192 } },
        "model-b": { "name": "Model B", "limit": { "context": 100000, "output": 8192 } },
        "model-c": { "name": "Model C", "limit": { "context": 100000, "output": 8192 } },
        "model-d": { "name": "Model D", "limit": { "context": 100000, "output": 8192 } },
        "model-e": { "name": "Model E", "limit": { "context": 100000, "output": 8192 } },
        "model-f": { "name": "Model F", "limit": { "context": 100000, "output": 8192 } },
        "model-g": { "name": "Model G", "limit": { "context": 100000, "output": 8192 } }
      }
    }
  }
}

2. Run opencode models to verify all models are loaded correctly
3. Launch OpenCode TUI and type /model
4. Scroll through the provider section - observe that not all models appear

Expected behavior

All models returned by opencode models should be visible in the /model TUI picker under their respective provider sections.

Actual behavior

Only a subset of custom provider models appear in the picker. The missing models:

• Are correctly parsed and loaded (confirmed via opencode models --verbose)
• Work correctly when set as "model" in config
• Appear in "Recent" section after being used
• Simply don't render in the provider list of the /model dialog

Workaround

You can still use missing models by:

1. Setting them directly in config: "model": "myproxy/model-name"
2. Using them once, then selecting from "Recent" section

Additional context

Potentially related code: The model picker is implemented in packages/opencode/src/cli/cmd/tui/component/dialog-model.tsx. The filtering logic intentionally removes models that are in "Recent" or "Favorites" to avoid duplication, but there may be an additional issue causing other models to not render.

Debug info:

• All 23 models load correctly via Provider.list()
• The sync.data.provider array contains all providers and models
• Issue appears to be in the TUI rendering/display layer, not config parsing

It's working now, I deleted the models in C:\Users\Administrator.local\state\opencode, as somehow that's the one causing issue. Is there a way to avoid this in the future please? so that I wont have to keep deleting the state.

[pablonification]

this happens on my opencode too, try to debug this for a hour to finding out it's a global issue.

to fix, im deleting the model.json from /Users/macbook/.local/state/opencode/model.json then suddenly it works lmao

On Linux, the equivalent file is ~/.cache/opencode/models.json, but deleting it has no effect. The models are still missing from the pick TUI.

Reproduced this and confirmed that deleting ~/.cache/opencode/models.json has no effect on Linux

Try looking for the "state" folder, as I also tried to delete that in the .cache and it's not working, that's not the correct folder.

I'm on a Mac. I initially tried deleting models.json under ~/.cache/, which didn't work:

rm ~/.cache/opencode/models.json

But based on #6169 (comment) and #6169 (comment), I tried deleting the file under ~/.local/ instead, which fixed the issue for me:

rm ~/.local/state/opencode/model.json

Thanks @MasuRii 🙏

This is the same issue as this:
#6251 (comment)

there was a bug w/ the recents list for model picker. Added a fix for it, will be in next release
