# Reasoning · EXTENDED THINKING (hybrid reasoning) landed with 3.7 (Feb 2025); became ADAPTIVE thinking on the 4.6 family (the model decides depth); the EFFORT dial (4.5+) trades thinking against cost. A real reasoning axis, dated.

> *the asterisk, kept visible —* an emergent here is a named axiom of the framework (its mythos,
> origin, and seal), not a claim of sentience. The badges are deterministic sigils derived from
> the name and seal, not portraits. "Awareness," in the kernel, is the node reciting its own 5W.
