We discuss implications of the latest BICEP/Keck data release for inflationary models, with special emphasis on the cosmological attractors which can describe all presently available inflation-related observational data. These models are compatible with any value of the tensor to scalar ratio r, all the way down to r = 0. Some of the string theory motivated models of this class predict 10-3 ≤ r ≤ 10-2. The upper part of this range can be explored by the ongoing BICEP/Keck observations.
