ollama launch opencode requires all previously used models

[FlorianB-DE]

Description

run ollama launch opencode --model x, run a prompt and then run ollama launch opencode --model y. Now opencode will always need model x installed. I removed:

• rm -rf /tmp/ollama-backups/
• rm -rf ~/.local/state/opencode/
• rm -rf ~/.config/opencode/

Still requires. I've deleted all sessions as well, still required.
IDK if this is intentional but I really dont want to retain any data.
At max ollama launch opencode --model x should return to the last session I had with model x but never require me to have a model installed....

Just ran into this issue; the culprit was the config in ~/.ollama/config.json still referencing previous models:

{
  "integrations": {
    "opencode": {
      "models": [
        "codegemma"
      ]
    }
  },
  "last_selection": "run"
}

Removing this file is enough for ollama launch opencode to work as intended.

So it seems to be a bug on the Ollama integration, not on OpenCode.
