Unifying Sentiment Labels Across a BERT Classifier and a Prompt-Completion LLM
You are rolling out a polarity (positive/negative/neutral) classifier for customer chat transcripts. For latency reasons, the product team wants to use a fine-tuned BERT single-text classifier in the primary path, but also wants an LLM prompt-completion fallback when the BERT model’s top probability is below 0.55. The analytics team requires that downstream dashboards see a single, consistent label set {positive, negative, neutral} regardless of which model produced the decision, and they will reject any output that cannot be deterministically mapped into exactly one of those three labels.

A developer is building a sentiment analysis model using a standard transformer-based architecture. To classify a given sentence, the model must first convert the entire sequence of token outputs into a single, fixed-size vector representation that can be passed to a final prediction layer. According to the standard procedure for this type of task, how is this single representative vector generated?
A data scientist is using a pre-trained transformer model for a sentiment analysis task. Arrange the following steps in the correct sequence to describe how the model processes a single sentence to produce a classification.
