Spotify teams mostly do something along the lines of ScrumBan, Kanban with some of the Scrum ceremonies, although there are other agile techniques used in different teams as well. When people talk about the “Spotify Model” what they mean is the way Spotify found to scale agile beyond the team to a larger organization. Agile originally had issues scaling to larger organization because of the dependencies between the teams. Those dependencies created bottlenecks because teams had to commit to deliverables to each other which tended to create waterfall-like elements which diminished the value of Agile. Spotify found a way to avoid these issues by focusing on giving teams a lot more autonomy and removing dependencies wherever possible.
