The Frenchman has spent three years with Toro Rosso but will be replaced by Max Verstappen for the 2015 campaign, with the Dutchman set to become the youngest driver in the sport's history at 17.
And Vergne revealed that he is keeping his options open should he be unable to find an alternative seat on the F1 grid.
"There are so many drivers who wanted to focus on F1 and got nowhere," he is quoted as saying by Autosport. "So I am not stupid - I have my eyes open I would say.
"I would really love to race. It depends on the chance I will get to drive in a race, but at the moment my focus is on getting a race seat."
Vergne saw former team-mate Daniel Ricciardo depart for Red Bull's flagship team ahead of the 2014 season - the Australian since proving more than a match for new colleague and world champion Sebastian Vettel.
And Vergne believes that he has the talent to emulate Ricciardo's progress.
"If the key people in some teams trust me, and trust that I can make it [then I have a chance]," he added. "Doing three years here [at Toro Rosso] makes me very strong.
"Daniel in a way is a good help for me because some teams expect world champion drivers, but maybe [the future] is not in world champion drivers, but in younger drivers who are really hungry and motivated, and that's what I am.
"When you look at my results compared to Daniel all of our career, I have the potential to be what he is."
The F1 season continues in Singapore this weekend, where Vergne will be chasing his fifth points finish of the campaign.
