for b>=2 integer (and a and t arbitrary), at least for b>=2 and b<=6.
(Apologies for mixing Mathematica and Python notation.)
This might be immediately useful if predictRecall checks for b (small?) integer.
This can be even more useful if we can find a way to make b always integer in our Ebisu models—easy to do when a quiz is a success, but a bit harder to do when a quiz is a failure: basically we have to search t' (t-prime in the readme) that makes b an integer.
Then, predicting recall at any given time is a rational polynomial, very fast to calculate, no need for Gamma or Beta functions. We could always try to make b=2 even.
(One question I have is, right now with version 1.0, we rebalance the model to roughly near the half-life so a and b aren't too different. Are there t's that yield Beta distributions that are more faithful to the GB1 posterior than others?)
