## Install
|
|
|
|
Install the [Codex CLI](https://developers.openai.com/codex/cli/):
|
|
|
|
```
|
|
npm install -g @openai/codex
|
|
```
|
|
|
|
## Usage with Ollama
|
|
|
|
<Note>Codex requires a larger context window. It is recommended to use a context window of at least 32K tokens.</Note>
|
|
|
|
To use `codex` with Ollama, use the `--oss` flag:
|
|
|
|
```
|
|
codex --oss
|
|
```
|
|
|
|
### Changing Models
|
|
|
|
By default, codex will use the local `gpt-oss:20b` model. However, you can specify a different model with the `-m` flag:
|
|
|
|
```
|
|
codex --oss -m gpt-oss:120b
|
|
```
|
|
|
|
### Cloud Models
|
|
|
|
```
|
|
codex --oss -m gpt-oss:120b-cloud
|
|
```
|
|
|
|
|
|
## Connecting to ollama.com
|
|
|
|
|
|
Create an [API key](https://ollama.com/settings/keys) from ollama.com and export it as `OLLAMA_API_KEY`.
|
|
|
|
To use ollama.com directly, edit your `~/.codex/config.toml` file to point to ollama.com.
|
|
|
|
```toml
|
|
model = "gpt-oss:120b"
|
|
model_provider = "ollama"
|
|
|
|
[model_providers.ollama]
|
|
name = "Ollama"
|
|
base_url = "https://ollama.com/v1"
|
|
env_key = "OLLAMA_API_KEY"
|
|
```
|
|
|
|
Run `codex` in a new terminal to load the new settings.
