On 1 September 2026 the reference pages still listed all six models retiring that day with no deprecation notice anywhere on them, so verifying against the reference pages alone would have confirmed a list six models wrong. Task groupings are GitHub's own; a model GitHub places in no group carries an empty grouping here rather than one inferred from its name.",
