A language model developer is designing a new system and proposes omitting the use of a special, unique token to signal the beginning of every input sequence. Critique this decision. Explain one significant potential problem this could cause for the model's ability to generate coherent and predictable text.

The $$\langle \mathrm{SOS} \rangle$$ (Start of Sequence) token, or $$\langle s \rangle$$, is a special symbol used to mark the beginning of an input sequence in a Large Language Model. It is often denoted as the first token, $$x_0$$, in the sequence.

Start of Sequence (SOS) Token

A specific language model requires that any input sequence must begin with a special symbol, denoted as `[START]`, to signal the beginning of the text. Given the sentence 'The model predicts.', which of the following token sequences is correctly formatted for this model?

Based on the scenario described, what is the most likely reason for the model's failure to generate a coherent response, and what specific change should be made to the input token sequence to correct the issue?
