Elements Fast

Overview

Elements Fast is for the edits that happen while someone watches: a rename, a fix applied from a review comment, a function filled in from its signature. It carries less context than standard Elements and returns sooner, and it is priced for the latency rather than the depth.

How it behaves

Short-range edits while you watch.

Speed and depth trade against each other across a family. The faster versions cost more per rung, not less: what is being bought is a shorter wait, and reserving capacity to answer promptly costs more than using it whenever it is free.

Choosing this model

Reach for it when

• Inline completions and short edits
• Applying a suggested fix
• Quick reviews of a single file

Reach for something else when

• Use elements when the change needs surrounding context.
• Use elements.codebase when the change spans files.

Others in the Elements family

• Elements: The coding model. Edits, reviews and builds.
• Elements Codebase: Repository-wide context for cross-file work and migrations.
