GigaChat

GigaChat is Sberbank's own large language model, and this is its official Telegram bot — confirmed on the bot's own page as a free neural network from Sber. It works through four simple modes: write original text, explain a complex term in plain words, summarize a long text into a short version, and draw a picture from a description. Voice messages are accepted directly, so you can talk to it instead of typing.

Being an official corporate bot rather than a hobby project gives it two practical advantages: it is unlikely to disappear overnight, and it is tuned specifically for Russian, which shows in how naturally it handles Russian grammar, idioms and context compared to bots built primarily around English-first models. It also draws images through Sber's Kandinsky model without leaving the chat.

The trade-off of an all-in-one general assistant is that it is not a specialist in any one task — for pure ChatGPT-style conversation, heavy-duty image generation, or long-document analysis, a dedicated bot may go further. But as a free, official, no-fuss Russian-language AI assistant that also draws and listens to voice messages, GigaChat is hard to beat on price and reliability.
