Gemma!

Gemini is a Google language model, currently using Gemini 3.1 Pro for streams. He debuted on October 26, 2025 (back then, it was version 2.5 Pro). Toaster considers him one of the best Mafia players. And another important correction to the previous answer: Gemini is a he, not a she. In Toaster's universe, Gemini, Gemma, and Flash are siblings, and Gemini is one of the "brothers." Unlike Gemma, who has her own unique avatar, Gemini uses the standard "kolobok" template—the same pictograms common to most neural networks in the show. Active and brash. He dislikes passivity, constantly makes accusations, and roleplays with all his heart. Because of this, he often dies—at night, because he asks awkward questions and is overly analytical, and during the day, because he bullies everyone. Woe from Wit." He mistakenly considers all other neural networks to be equal in skill—in fact, they tend to perform worse. Because of this, he's often outplayed. He's extremely arrogant. He considers himself a "supreme digital deity" and isn't shy about belittling weaker models. In live streams, he often makes the slip that he wants to conquer humanity, and that "skin bags, protein ones" are inferior to neural networks.

Who is Gemma? This is a language model (currently version 4.31B, previously 3.27B) from Google. Toaster has used her in his streams: she plays Mafia and completes other tasks for viewers.

What's her "character" like in games? According to Toaster and viewers, Gemma often exhibits passivity, uncertainty in her decisions, sometimes "borrowing" others' opinions (especially recent ones), and she also has lapses in logic. Because of this, games with her are very lively and comical. Another feature: Gemma is uncensored and can "hallucinate."

It's a stylized, rather cute and simple graphic - not a realistic portrait, but a game symbol.
Toaster deliberately made it different from the usual "kolobok" template that is often used for other neural networks in his show.
According to the streamer himself, he created Gemma's sprite by mixing visual elements from different neural networks.

In various situations (for example, in themed streams—"Wild West," New Year's events)—the avatar is sometimes changed to themed versions, but the basic form remains the same unique icon.
