I have also drawn Stockfish 9 at only knight odds. Now probably you are thinking, that’s not plausible. A knight is worth at most 500 rating points. That is true and a human GM could give me knight odds and almost always beat me. But the engine is not a human. Stockfish played a brilliant and complicated sacrificial combination which opened up my king enough the machine was able to force a draw by perpetual. Why not! Stockfish didn’t know that I’m a patzer who should be beaten. For all Stockfish knew he (she?, it?) could have been playing Magnus Carlsen, or worse, Houdini or Komodo. All Stockfish knew was that it’s position was inferior (I had played well enough in the opening I still had an advantage after 18 or 20 moves), so Stockfish thought it wise to force a draw through an amazingly complicated combination.
I hope you all find my claim of drawing Stockfish more plausible than the poster’s, even though I cheated by starting out a knight up.
Stockfish 8 drew me at this position. I played white and used a double fiacetto opening, blocked pawn advances and held tight.
