-Almost all modern [[large language model|LLMs]] map relatively low-dimensional hidden states to high-dimensional probability distributions over [[tokenizer|tokens]] using a single [[matrix]] and a [[softmax]] operation. The [[rank]] of this transformation is limited to the hidden size, so not all valid probability distributions can be represented. This has a number of [[consequences]].
+Almost all modern [[large language model|LLMs]] map relatively low-dimensional hidden states to high-dimensional probability distributions over [[tokenizer|tokens]] using a single [[matrix]] and a [[softmax]] operation. The [[rank]] of this transformation is limited to the hidden size, so not all valid probability distributions can be represented. Some mixtures of tokens are not representable without introducing additional higher-probability tokens, particularly where a mixture of such would not be common in the training data. This has a number of [[consequences]].
