### With http proxy

If you are unable to connect , you can try using a proxy. HTTP and SOCKS5 proxies are supported. For example:

```bash
# 1. pass the proxy address by -p/--proxy
fgpt -p 'socks5://127.0.0.1:9080' "Linux command to list files in a directory"

# 2. pass the proxy address by environment variable
export HTTPS_PROXY='socks5://127.0.0.1:9080'
fgpt "Linux command to list files in a directory"

# 3. use alias to set the proxy address
alias fgpt='fgpt -p "socks5://127.0.0.1:9080"'
fgpt "Linux command to list files in a directory"
```

### Dump stats

```bash
fgpt --stats "Linux command to list files in a directory"
```

## Use by docker

## How to use Reverse Proxy

Offering free self-hosted API access to ChatGPT. This is useful if you want to use the OpenAI API without needing to sign up for an API key.

### 1. Start the server

```bash
fgpt -s 127.0.0.1:4090
```

Your local server will now be running and accessible at: `http://127.0.0.1:4090/v1/chat/completions`

### 2. Example Usage with OpenAI Libraries

```python
import openai
openai.api_key = 'nothing'
openai.base_url = "http://127.0.0.1:4090/v1/"

completion = openai.chat.completions.create(
    model="gpt-3.5-turbo",
    messages=[
        {"role": "user", "content": "Write a javascript simple code"},
    ],
)

print(completion.choices[0].message.content)
```

or test with curl:

```bash
curl -X POST -H "Content-Type: application/json" -d '{"model":"gpt-3.5-turbo","messages":[{"role":"user","content":"Write a javascript simple code"}], "stream":true}' http://127.0.0.1:4090/v1/chat/completions
 ```

```bash
curl -X POST -H "Content-Type: application/json" -d '{"model":"gpt-3.5-turbo","messages":[{"role":"user","content":"Write a javascript simple code"}]}' http://127.0.0.1:4090/v1/chat/completions
