+title: ChatGPT Desktop
+description: Use Ollama models in ChatGPT Desktop.
+---
+
+ChatGPT Desktop includes Codex, OpenAI's desktop coding agent. Ollama adds compatible local and cloud models to Codex's model picker alongside ChatGPT's native models.
+
+## Prerequisites
+
+- Ollama v0.34.0 or newer
+
+If ChatGPT is not installed, Ollama offers to download it during setup.
+
+## Connect ChatGPT
+
+1. Open the Ollama desktop app and select **Apps**.
+2. Toggle **ChatGPT (Desktop)** to On.
+3. Follow the setup prompts. If ChatGPT is already open, Ollama asks to restart it before the new models appear.
+4. Open the ChatGPT desktop app and use Codex mode.
+
+## Choose models
+
+Open Ollama **Settings**, select **Apps**, then select ChatGPT. Choose up to five compatible local or cloud models and save your changes. Ollama asks to restart ChatGPT when a model change needs one.
+
+## Disconnect ChatGPT
+
+Open Ollama **Apps** and turn ChatGPT off. Ollama restores ChatGPT's connection settings and usual profile. If ChatGPT is open, Ollama asks to restart it so the change takes effect.
+
+## Codex behavior and limits
+
+- Only requests made with an Ollama model go to Ollama. ChatGPT's native models keep using their usual provider.
+- Ollama models are for Codex mode. Regular Chat and voice keep using their usual ChatGPT connection.
+- Codex manages sessions. Ollama routes model requests and compaction when Codex asks for it, but does not store ChatGPT sessions.
+- Web search uses Ollama's web-search service when you use an Ollama model. It requires Ollama sign-in and is limited to three calls per response.
+
+## Related integrations
+
+- Use Codex from a terminal with [Codex CLI](/integrations/codex).
+- Connect other desktop apps from [Claude Desktop](/integrations/claude-desktop).

-title: Codex App
----
-
-Codex App is OpenAI's desktop coding agent for macOS and Windows. Ollama configures the app to use Ollama's OpenAI-compatible endpoint, so Codex can work with local models and Ollama Cloud models in the desktop app.

-  alt="Codex App with Ollama selected"
-  style={{ borderRadius: "12px" }}
-/>
-
-## Install
-
-Install the [Codex App](https://developers.openai.com/codex/quickstart/) for macOS or Windows.
-
-<Note>Codex App support is available in Ollama v0.24.0 and newer.</Note>
-
-
-## Quick setup
-
-```shell
-ollama launch codex-app
-```
-
-Once Codex App opens, start a task or open a repository as usual.
-
-## Built-in browser
-
-Codex App can open local servers and sites in its built-in browser. Annotate directly on the page to request changes.
-
-<img
-  src="/images/codex-app-annotate.png"
-  alt="Codex App browser annotations"
-  style={{ borderRadius: "12px" }}
-/>
-
-## Review mode
-
-Use review mode to inspect code changes, leave comments, and iterate on fixes without leaving the app.
-
-<img
-  src="/images/codex-app-review.png"
-  alt="Codex App review comments"
-  style={{ borderRadius: "12px" }}
-/>
-
-### Run directly with a model
-
-```shell
-ollama launch codex-app --model kimi-k2.6:cloud
-```
-
-Use a local model by passing its model name:
-
-```shell
-ollama launch codex-app --model gemma4:31b
-```
-
-Running `ollama launch codex-app` is persistent and will have your model selected next time you open Codex.
-
-
-### Restore Codex App
-
-To switch Codex App back to the profile you were using before `ollama launch codex-app`, run:
-
-```shell
-ollama launch codex-app --restore
-```
-
-Ollama restores Codex App's settings and configs. If Codex App is open, Ollama asks before restarting it.
-
-
-The Codex CLI profile managed by `ollama launch codex` is left separate from the Codex App profile.
-
-Before overwriting Codex App config files, Ollama Launch saves backups under `~/.ollama/backup/codex-app/`. On Windows, `~` resolves to your user profile directory.
-
-## Troubleshooting
-
-If Codex App does not open after setup, open Codex manually once and run `ollama launch codex-app` again.
-
-If Codex App is already running and does not switch models, allow Ollama to restart it when prompted, or quit Codex App and run `ollama launch codex-app` again.
