http://(Grok.com) (not the superGrok inside Twitter/X) now supports uploading your own skills. The CZ skill distilled earlier is finally coming in handy. Tried out the skill feature, and here are some limitations: 1. Uploaded skill file packages can't exceed 10M, and individual files can't be larger than 5M. 2. No API call capabilities. 3. Skills run in Grok's sandbox environment and can execute some automated tasks like file editing. I have two ready-to-use ones in my GitHub repo: github.com/lianyanshe-ai/fupeng-perspective github.com/lianyanshe-ai/cz-perspective You can download them and upload to Grok for use. But honestly, I feel like the Grok model is kind of dumb. The results aren't great, so it might be more suitable for certain research or investment-related tasks.
