How is options implied volatility for a stock determined?

So TWS uses linear interpolation of strike-volatility for options of a given maturity, then linear interpolation of variance between maturities. Standard (and simple) stuff.

I use that too, but also several advanced volatility models which again:
- start with the fundamentals
- make sense analytically (mathematically)
- are actually confirmed trough backtests
