After setting, it will automatically create the configuration file. Of course, you can also manually set the configuration file.

api_key: "<YOUR SECRET API KEY>"  # Request via https://platform.openai.com/account/api-keys
organization_id: "org-xxx"        # optional, set organization id
model: "gpt-3.5-turbo"            # optional, choose a model
temperature: 1.0                  # optional, see https://platform.openai.com/docs/api-reference/chat/create#chat/create-temperature
save: true                        # optional, If set true, aichat will save chat messages to message.md

connect_timeout: 10               # optional, Set a timeout in seconds for connect to gpt.

You can use .info to view the current configuration file path and roles file path.

You can use Enviroment Variables to customize certain configuration items.


We can let ChatGPT play a certain role through prompt to make it better generate what we want.

We can predefine a batch of roles in roles.yaml.

We can get the location of roles.yaml through the repl's .info command or cli's --info option.

For example, we define a role

- name: shell
  prompt: >
    I want you to act as a linux shell expert.
    I want you to answer only with bash code.
    Do not provide explanations.

Let ChatGPT answer questions in the role of a linux shell expert.

.role shell

shell〉 extract encrypted zipfile app.zip to /tmp/app
mkdir /tmp/app
unzip -P PASSWORD app.zip -d /tmp/app

We have provided many awesome Role Examples.

.prompt - use GPT prompt

When you set up a prompt, every message sent later will carry the prompt.

{ .prompt
I want you to translate the sentences I wrote into emojis.
I will write the sentence, and you will express it with emojis.
I just want you to express it with emojis.
I want you to reply only with emojis.

P〉You are a genius

P〉I'm embarrassed

.prompt actually creates a temporary role internally, so run .clear role to clear the prompt.

When you are satisfied with the prompt, add it to roles.yaml for later use.

.role - let the ai play a role

Select a role.

.role emoji
name: emoji
prompt: I want you to translate the sentences I wrote into emojis. I will write the sentence, and you will express it with emojis. I just want you to express it with emojis. I don't want you to reply with anything but emoji. When I need to tell you something in English, I will do it by wrapping it in curly brackets like {like this}.
temperature: null

AI play the role we specified

.conversation - start a context-aware conversation

By default, aichat behaves in a one-off request/response manner.

You can run .conversation to enter context-aware mode, or set config.conversation_first true to start a conversation immediately upon repl.


$list 1 to 5, one per line                                                              4089

$reverse the list                                                                       4065

When enter conversation mode, prompt will change to , A number will appear on the right, which means how many tokens left to use. Once the number becomes zero, you need to start a new conversation.

Exit conversation mode

.clear conversation                                                                    4043
