Table of Contents

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. Exit interactive mode by simply typing 'exit'.
  • 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.
  • 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.
  • 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, use the --set-model and --set-max-tokens flags. To verify your current settings, use the --config or -c flag. The newly added omit_history configuration option adds another layer of customization to your user experience.

Linux (arm64)

curl -L -o chatgpt https://github.com/kardolus/chatgpt-cli/releases/download/v1.3.1/chatgpt-linux-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
  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 three-tier configuration strategy, with different levels of precedence assigned to default values, the config.yaml file, and environment variables, in that respective order.

Configuration variables:

Variable Description Default
name The prefix for environment variable overrides. 'openai'
api_key Your OpenAI API key. (none for security)
model The GPT model used by the application. 'gpt-3.5-turbo'
max_tokens The maximum number of tokens that can be used in a single API call. 4096
thread The name of the current chat thread. Each unique thread name has its own context. 'default'
omit_history If true, the chat history will not be used to provide context for the GPT model. false
url The base URL for the OpenAI API. 'https://api.openai.com'
completions_path The API endpoint for completions. '/v1/chat/completions'
models_path The API endpoint for accessing model information. '/v1/models'

The defaults can be overridden by providing your own values in the user configuration file, named .chatgpt-cli/config.yaml, located in your home directory.

The structure of the user configuration 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: 8192

This alters the model to gpt-3.5-turbo-16k and adjusts max_tokens to 8192. 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 two flags for swiftly modifying the model and max_tokens parameters in your user configured config.yaml. These flags are --set-model 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.

Development

To start developing, set the OPENAI_API_KEY environment variable to your ChatGPT secret key. Follow these steps for running tests and building the application:

  1. Run the tests using the following scripts:

    For unit tests, run:

    ./scripts/unit.sh

    For integration tests, run:

    ./scripts/integration.sh

    For contract tests, run:

    ./scripts/contract.sh

    To run all tests, use:

    ./scripts/all-tests.sh
  2. Build the app using the installation script:

    ./scripts/install.sh
  3. After a successful build, test the application with the following command:

    ./bin/chatgpt what type of dog is a Jack Russel?
  4. As mentioned previously, the ChatGPT CLI supports tracking conversation history across CLI calls. This feature creates a seamless and conversational experience with the GPT model, as the history is utilized as context in subsequent interactions.

    To enable this feature, you need to create a ~/.chatgpt-cli directory using the command:

    mkdir -p ~/.chatgpt-cli
