The exact nature of Vettel's contract with Red Bull is unclear, but the German driver said he was tied to the constructor until the end of 2014.
Speculation has surrounded Vettel's future at Red Bull since Ferrari principal Stefano Domenicali said in June the 25-year-old and Ferrari driver Fernando Alonso could "easily co-exist together".
Alonso, a double world champion who was narrowly beaten to the title by Vettel in Brazil, has a contract until the end of 2016 and is very much No.1 in the current line-up with Brazilian Felipe Massa.
"I have a contract until – I think you know better than me – at this stage, until the end of '14," Vettel said. "I'm very happy with what we have achieved so far and I don't think this story is over yet. I'm very happy and extremely committed to give everything I have, also in the next years when I'm with them.
"At the moment, I don't see any point thinking about another team or something else. I'm extremely happy in the position I am. It's incredible what we have achieved."
Massa's Ferrari contract runs until the end of next year.
Meanwhile, Lewis Hamilton will join Mercedes in the new year eager to show them he still has a few tricks up his sleeve.
The 27-year-old faces one final emotional pull this week when he visits the McLaren Technology Centre in Woking to say his goodbyes, but said: "Leaving McLaren is definitely tough, but I'm looking forward to next year. It's going to be something new, a new experience, and we'll see what happens.
"All I know is I'm going to give it absolutely everything and hope we can be competitive and that the future will be bright. Hopefully, as a driver who has been winning, they will be excited to have me there."
