Claude 5.5: A Recommended Task-Based Session

A usage recommendation challenges the habit of lengthy single conversations. With Claude 5.5, grouping heterogeneous requests in the same session overloads the context, degrades responses, and leads to increased token consumption. A dedicated session per task is advised.

A single session overloads the context and harms quality

Using a single session for multiple different tasks causes the model to reread the entire history with each new request. This method fills the context window with information that is not relevant to the current task. This contextual noise can harm the model's performance, lead to unnecessary token usage, and generate overly generic responses.

Open a conversation per task: the best practice

It is recommended to create a separate session for each specific task, rather than grouping unrelated requests in the same conversation. The use of a "catch-all" session is identified as a mistake, and it is noted that this practice is not as effective with Claude.
