If you dig into the the margins they aren't looking very good, even if they got a fair number of eventual winners correct.
Predicted vs Actual (FiveThirtyEight's averages vs NYTimes' current tally; Biden's margin is positive)
PA: +4.7% vs +.5% (-4.2%)
FL: +2.5 vs -3.4 (-5.9)
TX: -1.5 vs -5.9 (-4.4)
OH: -0.6 vs -8.1 (-7.5)
PA: +4.7 vs +0.5 (-4.2)
IA: -1.5 vs -8.2 (-6.7)
NC: +1.7 vs -1.4 (-3.1)
WI: +8.3 vs +0.6 (-7.7)
GA: +0.9 vs +0.1 (-.8)
MI: +8.0 vs +2.6 (-5.4)
AZ: +2.6 vs +0.6 (-2.0)
NV: +6.2 vs +2.0 (-4.2)
They pretty consistently overpredicted Biden's margin by about 4-7% in almost all of the swing states. Even if that's within, or close to, the margin of error; there's a systemic issue if it's happening in almost every state.

Edit: Added AZ and NV; and the difference
