Anything usable for everyday nonenglish chat on limited mac HW?

Hello there, got recently a Macbook Air M4 with just 16gb ram and 256gb ssd. To end my hopes faster- is there any model to chat general purpose ways with any of the current model usable enough with my specs, for czech langauge?

For coding Im very happy sith Codex, im just looking for chat with private stuff I dont wanr leaving my computer
