This is a plugin that enables support for completions by xAI's Grok models, and this is only useful used in conjunction with chatty-ai.
After installing the chatty-ai system, you should also register for an xAI account and obtain an API key. Once you have the key please set it as an environment variable named XAI_API_KEY (configurable), so that it can be accessed by the plugin when making completions.
In ./sampleconfig/config.lua you can find simple instructions to do this.
