Features

• Streaming mode: Real-time interaction with the GPT model.
• Query mode: Single input-output interactions with the GPT model.
• Interactive mode: The interactive mode allows for a more conversational experience with the model. Prints the token usage when combined with query mode.
• Thread-based context management: Enjoy seamless conversations with the GPT model with individualized context for each thread, much like your experience on the OpenAI website. Each unique thread has its own history, ensuring relevant and coherent responses across different chat instances.
• Sliding window history: To stay within token limits, the chat history automatically trims while still preserving the necessary context. The size of this window can be adjusted through the context-window setting.
• Custom context from any source: You can provide the GPT model with a custom context during conversation. This context can be piped in from any source, such as local files, standard input, or even another program. This flexibility allows the model to adapt to a wide range of conversational scenarios.
• Model listing: Access a list of available models using the -l or --list-models flag.
• Thread listing: Display a list of active threads using the --list-threads flag.
• Advanced configuration options: The CLI supports a layered configuration system where settings can be specified through default values, a config.yaml file, and environment variables. For quick adjustments, various --set-<value> flags are provided. To verify your current settings, use the --config or -c flag.
• Availability Note: This CLI supports gpt-4, gpt-3.5-turbo, and Perplexity’s models (e.g., llama-3.1-sonar-small-128k-online). However, the specific ChatGPT model used on chat.openai.com may not be available via the OpenAI API.

Prompt Support

We’re excited to introduce support for prompt files with the --prompt flag in version 1.7.1! This feature allows you to provide a rich and detailed context for your conversations directly from a file.

Using the --prompt Flag

The --prompt flag lets you specify a file containing the initial context or instructions for your ChatGPT conversation. This is especially useful when you have detailed instructions or context that you want to reuse across different conversations.

To use the --prompt flag, pass the path of your prompt file like this:

chatgpt --prompt path/to/your/prompt.md "Use a pipe or provide a query here"

The contents of prompt.md will be read and used as the initial context for the conversation, while the query you provide directly will serve as the specific question or task you want to address.

Example

Here’s a fun example where you can use the output of a git diff command as a prompt:

git diff | chatgpt --prompt ../prompts/write_pull-request.md

In this example, the content from the write_pull-request.md prompt file is used to guide the model's response based on the diff data from git diff.

curl -L -o chatgpt https://github.com/kardolus/chatgpt-cli/releases/latest/download/chatgpt-freebsd-arm64 && chmod +x chatgpt && sudo mv chatgpt /usr/local/bin/

Windows (amd64)

Download the binary from this link and add it to your PATH.

Choose the appropriate command for your system, which will download the binary, make it executable, and move it to your /usr/local/bin directory (or %PATH% on Windows) for easy access.

Getting Started

1. Set the OPENAI_API_KEY environment variable to your ChatGPT secret key. To set the environment variable, you can add the following line to your shell profile (e.g., ~/.bashrc, ~/.zshrc, or ~/.bash_profile), replacing your_api_key with your actual key:

   export OPENAI_API_KEY="your_api_key"
   

2. To enable history tracking across CLI calls, create a ~/.chatgpt-cli directory using the command:

   mkdir -p ~/.chatgpt-cli
   

   Once this directory is in place, the CLI automatically manages the message history for each "thread" you converse with. The history operates like a sliding window, maintaining context up to a configurable token maximum. This ensures a balance between maintaining conversation context and achieving optimal performance.

   By default, if a specific thread is not provided by the user, the CLI uses the default thread and stores the history at ~/.chatgpt-cli/history/default.json. You can find more details about how to configure the thread parameter in the Configuration section of this document.

3. Try it out:

   chatgpt what is the capital of the Netherlands
   

4. To start interactive mode, use the -i or --interactive flag:

   chatgpt --interactive
   

   If you want the CLI to automatically create a new thread for each session, ensure that the auto_create_new_thread configuration variable is set to true. This will create a unique thread identifier for each interactive session.

5. To use the pipe feature, create a text file containing some context. For example, create a file named context.txt with the following content:

   Kya is a playful dog who loves swimming and playing fetch.
   

   Then, use the pipe feature to provide this context to ChatGPT:

   cat context.txt | chatgpt "What kind of toy would Kya enjoy?"
   

6. To list all available models, use the -l or --list-models flag:

   chatgpt --list-models
   

7. For more options, see:

   chatgpt --help
   

Configuration

The ChatGPT CLI adopts a four-tier configuration strategy, with different levels of precedence assigned to flags, environment variables, a config.yaml file, and default values, in that respective order:

1. Flags: Command-line flags have the highest precedence. Any value provided through a flag will override other configurations.
2. Environment Variables: If a setting is not specified by a flag, the corresponding environment variable (prefixed with the name field from the config) will be checked.
3. Config file (config.yaml): If neither a flag nor an environment variable is set, the value from the config.yaml file will be used.
4. Default Values: If no value is specified through flags, config.yaml, or environment variables, the CLI will fall back to its built-in default values.

General Configuration

LLM-Specific Configuration

Custom Config and Data Directory

By default, ChatGPT CLI stores configuration and history files in the ~/.chatgpt-cli directory. However, you can easily override these locations by setting environment variables, allowing you to store configuration and history in custom directories.

Example for Custom Directories

To change the default configuration or data directories, set the appropriate environment variables:

export OPENAI_CONFIG_HOME="/custom/config/path"
export OPENAI_DATA_HOME="/custom/data/path"

If these environment variables are not set, the application defaults to ~/.chatgpt-cli for configuration files and ~ /.chatgpt-cli/history for history.

Variables for interactive mode:

• %date: The current date in the format YYYY-MM-DD.
• %time: The current time in the format HH:MM:SS.
• %datetime: The current date and time in the format YYYY-MM-DD HH:MM:SS.
• %counter: The total number of queries in the current session.
• %usage: The usage in total tokens used (only works in query mode).

The defaults can be overridden by providing your own values in the user configuration file. The structure of this file mirrors that of the default configuration. For instance, to override the model and max_tokens parameters, your file might look like this:

model: gpt-3.5-turbo-16k
max_tokens: 4096

This alters the model to gpt-3.5-turbo-16k and adjusts max_tokens to 4096. All other options, such as url , completions_path, and models_path, can similarly be modified. If the user configuration file cannot be accessed or is missing, the application will resort to the default configuration.

Another way to adjust values without manually editing the configuration file is by using environment variables. The name attribute forms the prefix for these variables. As an example, the model can be modified using the OPENAI_MODEL environment variable. Similarly, to disable history during the execution of a command, use:

OPENAI_OMIT_HISTORY=true chatgpt what is the capital of Denmark?

This approach is especially beneficial for temporary changes or for testing varying configurations.

Moreover, you can use the --config or -c flag to view the present configuration. This handy feature allows users to swiftly verify their current settings without the need to manually inspect the configuration files.

chatgpt --config

Executing this command will display the active configuration, including any overrides instituted by environment variables or the user configuration file.

To facilitate convenient adjustments, the ChatGPT CLI provides flags for swiftly modifying the model, thread , context-window and max_tokens parameters in your user configured config.yaml. These flags are --set-model , --set-thread, --set-context-window and --set-max-tokens.

For instance, to update the model, use the following command:

chatgpt --set-model gpt-3.5-turbo-16k

This feature allows for rapid changes to key configuration parameters, optimizing your experience with the ChatGPT CLI.

Azure Configuration

For Azure, use a configuration similar to:

name: azure
api_key: <your_key>
model: <not relevant, read from the completions path>
max_tokens: 4096
context_window: 8192
role: You are a helpful assistant.
temperature: 1
top_p: 1
frequency_penalty: 0
presence_penalty: 0
thread: default
omit_history: false
url: https://<your_resource>.openai.azure.com
completions_path: /openai/deployments/<your_deployment>/chat/completions?api-version=<your_api>
models_path: /v1/models
auth_header: api-key
auth_token_prefix: " "
command_prompt: '[%datetime] [Q%counter]'
auto_create_new_thread: false
track_token_usage: false
debug: false

You can set the API key either in the config.yaml file as shown above or export it as an environment variable:

export AZURE_API_KEY=<your_key>

Perplexity Configuration

For Perplexity, use a configuration similar to:

name: perplexity
api_key: ""
model: llama-3.1-sonar-small-128k-online
max_tokens: 4096
context_window: 8192
role: Be precise and concise.
temperature: 1
top_p: 1
frequency_penalty: 0
presence_penalty: 0
thread: test
omit_history: false
url: https://api.perplexity.ai
completions_path: /chat/completions
models_path: /models
auth_header: Authorization
auth_token_prefix: 'Bearer '
command_prompt: '[%datetime] [Q%counter] [%usage]'
auto_create_new_thread: true
track_token_usage: true
debug: false

You can set the API key either in the config.yaml file as shown above or export it as an environment variable:

export PERPLEXITY_API_KEY=<your_key>

You can set the API key either in the config.yaml file as shown above or export it as an environment variable:

export AZURE_API_KEY=<your_key>

Command-Line Autocompletion

Enhance your CLI experience with our new autocompletion feature for command flags!

Enabling Autocompletion

Autocompletion is currently supported for the following shells: Bash, Zsh, Fish, and PowerShell. To activate flag completion in your current shell session, execute the appropriate command based on your shell:

• Bash

  . <(chatgpt --set-completions bash)
  

• Zsh

  . <(chatgpt --set-completions zsh)
  

• Fish

  chatgpt --set-completions fish | source
  

• PowerShell

  chatgpt --set-completions powershell | Out-String | Invoke-Expression
  

Persistent Autocompletion

For added convenience, you can make autocompletion persist across all new shell sessions by adding the appropriate sourcing command to your shell's startup file. Here are the files typically used for each shell:

• Bash: Add to .bashrc or .bash_profile
• Zsh: Add to .zshrc
• Fish: Add to config.fish
• PowerShell: Add to your PowerShell profile script

For example, for Bash, you would add the following line to your .bashrc file:

. <(chatgpt --set-completions bash)

This ensures that command flag autocompletion is enabled automatically every time you open a new terminal window.

Markdown Rendering

You can render markdown in real-time using the mdrender.sh script, located here. You'll first need to install glow.

Example:

chatgpt write a hello world program in Java | ./scripts/mdrender.sh

Development

To start developing, set the OPENAI_API_KEY environment variable to your ChatGPT secret key.
