A quick google shows that the brand is real, started in Italy, and has been around for decades. https://www.google.com/search?q=Gios+Torino is a good start.
As for your bike, it's clearly been "modified" with
- bullhorn bars (possibly someone's flipped the old drops and hacked off the drops or maybe they were bought that way.
- dual pivot rim brake calipers - definitely a good idea to improve stopping
- replacement modern wheels with some significant depth compared to the old box-section rims from the 80s.
- single speed transmission - both derailleurs have been removed. Surprisingly the derailleur hanger is still in the frame. It is sadly common for those to be cut off. Also, the bike still has downtube shifter levers in place even though they serve no purpose.
I would call this a road bike, but it's not really a race bike without gears.
Loverly bike, you'll get a lot of enjoyment out of it.
: Update : Check your seatpost frame insertion!!!
I see some engravings on the silver part, which are well above the frame. If those are the "minimum insert line" then they need to be in the frame, not exposed. Otherwise you risk breaking your frame. You need at LEAST 100mm of seatpost inside the frame, ideally 150mm.
I'm speaking from experience here - I've personally broken two MTB, one folder and two road frames by doing this.
