Nothing on record matches that combination. That is a fact about the corpus rather than an error: this dataset covers models somebody judged notable, so the gaps in it are real gaps.

Counts are of models Epoch AI records as notable, not of every model released. The most recent month is always incomplete, because a model enters the dataset when it is reviewed rather than when it ships.
