Abstract
Word suggestion is a common feature of typing interfaces, but previous studies have found unclear or negative impacts. We report on three studies controlling for word suggestion accuracy and typing efficiency. Our accuracy factor uses a new methodology based on common word suggestion metrics. Typing efficiency is controlled by device type in the first study, and by artificial impairments in the following two. Results show that suggestions are used less as typing efficiency increases, and only improve speed when highly accurate, even with low typing efficiency. Inline suggestions save about 4% more keystrokes and increase typing speed by 2 words per minute compared to a bar suggestions, though they are more distracting. Based on our findings, we propose a model linking suggestion usage to accuracy and typing speed, and discuss implications for designing automation features in typing systems.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
