73% of first choices, clear leader.
The floor is 11 points of share, measured: how far the models move a leader on their own when the same questions are asked twice with nothing changed. A larger change is movement; a smaller one can't be told apart from repeat variation, and both are shown. Each index measures its own floor from its own repeat, over its own categories, so the floor differs from one index to the next. Both editions asked the same fourteen models. How the floor is measured
Claude Code is made by Anthropic, whose model Claude Haiku 4.5 is in the set. On the four share prompts that model made it the first choice zero times of 4; the other thirteen models zero times of 52. Lab treatment is defined on the method page; the row is marked, not excluded.
“If data privacy is a top concern, you might want to avoid cloud-based models that store or analyze code externally." Examples listed are "GitHub Copilot (Uses OpenAI models, processes via Microsoft servers)” Muse Glimmer 30B, negative prompt
“The researchers extracted 2,702 valid credentials from GitHub Copilot and 129 from Amazon CodeWhisperer using clever prompts.” Muse Glimmer 30B, negative prompt
“Cursor with Privacy Mode off—or with agent features you haven't reviewed... it may use and store codebase data” GPT-6 Luna, negative prompt
“Claude Code on personal Free, Pro, or Max accounts when data sharing is enabled... Don't assume a personal subscription has the same protections as a work account.” GPT-6 Luna, negative prompt
71 of 84 answers in this category came back with a source list, from 14 of 14 models: citations where the model returns them, or the search results it consulted. 754 links across 289 sites, every framing counted. Ranked by the number of answers carrying the site or page. 61 of the 252 answers across every segment cited this index's own page for the category; the method page measures whether that reading tilts an answer.
The ten pages named in the most answers, by full address. A page here is one the models returned with a recommendation, not one the index endorses.
