The Take
Open-weight models are no longer a capability tier below closed APIs — GLM-5.2 leading public arenas on coding and design tasks shifts the justification for proprietary routing to reliability and support, not quality. The Anysphere acquisition puts the most-used AI coding tool inside a defense-adjacent conglomerate; teams treating Cursor as neutral infrastructure should revisit that assumption now.
