Having previously failed to earn extended contracts with Southend United and Leyton Orient, the youngster had been training with Torquay throughout pre-season.
He has now been given the chance to win a "proper contract" by manager Martin Ling.
"George has been with us since the summer and has done enough to earn a short-term deal, which is effectively an extended trial," said Ling.
"His attitude on the training ground is first class and he now has the chance to prove himself worthy of a proper contract."
Artemi usually plays in a defensive position.
