"name": " The screencap shows a shot of a social media application interface, specifically a Mastodon instance. The interface is dark-themed, with a black background and white text. At the top, there is a header with options for hashtags, mentions, and language selection, along with a profile picture icon. Below the header, the text reads \"Posting as [@]Dendrobatus_Azureus[@]mastodon.bsd.cafe\" and \"Replying to [@]rl_dane.\" The user is typing a reply, with the text \"[@]rl_dane[@]polymaths.social\" visible. The keyboard is visible at the bottom of the screen, with various keys including numbers, letters, and special characters. The number of characters typed is displayed as 4991, and there is a blue \"post\" button on the right side. The overall layout is typical of a social media platform, with a focus on text input and reply functionality.\n\n Ovis2-8B\n\nš± Energy used: 0.231 Wh",
