Summary

Please add support for configuring a custom OpenAI API base URL in terminal-chat.

Problem Statement

Currently, terminal-chat appears to assume the default OpenAI API endpoint. This makes it difficult or impossible to use:

• OpenAI-compatible API providers
• self-hosted gateways / proxies
• Azure/OpenAI-compatible endpoints
• internal enterprise API gateways
• regional or custom routing setups
  For users in these scenarios, being able to specify a custom API base URL is very important.

Proposed Solution

Add a configuration option for the OpenAI API base URL, for example through:

• an environment variable such as OPENAI_BASE_URL or OPENAI_API_BASE
• a CLI flag
• a config file entry
  Example:

export OPENAI_API_KEY=your_key
export OPENAI_BASE_URL=https://your-custom-endpoint.example.com/v1
