its very strong i would say for writing passable code for algorithms where there are many documentation examples. Asking it to write an implementation of an algo im working on i found that it wrote passable code for CFML. It understood for example that arrays in CFML start at 1. it lies routinely or has extreme confidence which is something to watch for so for example it relied in on a BIF called ArrayShuffle() when i pointed out no such function existed it provided a replacement which was solid. Then i had to remove when var from one line of code where it was calling outside a function and ultmately you can't local scope a call in the way it was trying but very solid
