# November 27th - @ Mentions, Mito AI Server ### @ Mentions @ mentions make it easier than ever before to reference your variables, dataframes, and column headers in the AI chat. Type `@` in the AI chat input, and a smart dropdown appears displaying all available variables in your notebook. Select any variable to automatically include it in your prompt, providing the AI with precise context about what variables it should interact with. The result is faster prompting and more accurate AI responses. ### Mito AI Server Mito now comes batteries included. When using the Mito AI server, you no longer need to provide your own OPENAI\_API\_KEY. Instead, use ours for free to get started. Once you reach the free tier limit, either provide your own keys or upgrade to Mito Pro for more AI completions. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
