Usage

1. Provider Selection: On startup, choose your AI provider:

   • DeepSeek or OpenAI.

2. API Key Setup: If an API key is missing, the script prompts you to enter it.

3. Model Selection: For OpenAI, dynamically fetch and select models. For DeepSeek, predefined models are available.

4. Chat: Type messages to interact with the assistant. Use the following commands:

   • /openai: Switch to OpenAI.
   • /deepseek: Switch to DeepSeek.
   • /models: Re-select the model.
   • /quit: Exit the script.

5. Conversation History: Chat history is automatically saved in chat_history.json.

Example

$ ./chat.sh

=== NerdChat CLI (Provider: OPENAI, Model: gpt-3.5-turbo). Warning: For nerds only! ===

USER: Hi there!
ASSISTANT: Hello! How can I help you today?
(Type your message, or use commands: /openai, /deepseek, /models, /quit)

Message> What's the weather today?
ASSISTANT: I can't fetch the weather, but I can tell you how to retrieve it using an API!

---

Customization

1. Disable Colors: Set the color variables in the script to empty strings ("") for plain text output.
2. Use a Specific Provider by Default: Modify the script to set provider initially (e.g., provider="openai").
