// Pure helper for matching a model name against a set of known keys. No DOM —
|
|
// safe to import anywhere and to unit-test under node.
|
|

// Return the most specific (longest) key that is a substring of `name`, or null.
|
|
// Returning the first match instead made "gpt-4o-mini" match the shorter
|
|
// "gpt-4o" key — billing it at gpt-4o rates (~16x) and showing the wrong
|
|
// context window.
