ollama launch codex-app writes legacy profile config rejected by Codex App

[skyloevil]

What is the issue?

ollama launch codex-app can make Codex App fail to start a chat with Codex 0.134+ / 0.135 because Ollama writes Codex's legacy profile config into ~/.codex/config.toml.

The generated config includes a root profile selector and profile table like:

profile = "ollama-launch-codex-app"

[profiles.ollama-launch-codex-app]
model = "..."
openai_base_url = "http://127.0.0.1:11434/v1/"
model_provider = "ollama-launch-codex-app"
model_catalog_json = "/Users/.../.codex/ollama-launch-models.json"

Codex App then reports a startup/chat error like:

Error starting chat
failed to resolve feature override precedence: legacy `profile = "ollama-launch-codex-app"` config is no longer supported; use `--profile ollama-launch-codex-app` with `ollama-launch-codex-app.config.toml` instead

This is related to, but distinct from, #16348. That issue's main report is for ollama launch codex / Codex CLI. This issue tracks the codex-app path specifically.

Steps to reproduce

1. Use Ollama 0.24.0+ with a recent Codex App / Codex runtime that rejects legacy profile config.

2. Run:

   ollama launch codex-app --model gemma4:31b

3. Open Codex App and start a chat.

4. Observe the legacy profile config error.

Expected behavior

ollama launch codex-app should configure Codex App without writing legacy profile selectors or [profiles.ollama-launch-codex-app] into ~/.codex/config.toml.

For Codex App, Ollama can keep the app selection in root model, model_provider, and model_catalog_json, and keep the provider in [model_providers.ollama-launch-codex-app].

I opened #16364 for the Codex App side of this. #16351 appears to address the Codex CLI side.

1. Create a New Configuration File
   Create a new file specifically for your Ollama profile.
   Path: /home/user/.codex/ollama-launch.config.toml

2. Move the Legacy Settings
   Cut the configuration block from your main file and paste it into the new file.
   Open: /home/user/.codex/config.toml
   Find: The section starting with [profiles.ollama-launch]
   Action: Move all settings under that header into the new ollama-launch.config.toml file.
   Format: Remove the [profiles.ollama-launch] header line in the new file, leaving only the key-value pairs.

3. Try: codex --profile ollama-cloud

@ParthSareen - this works for codex cli but the issue persists for codex app on Macbook.

I got another change in for that - are you testing off main?
