GLM-4.5-X (Z.ai)
Active
No — GLM-4.5-X is not deprecated as of August 3, 2026. Z.ai has announced neither a deprecation nor a shutdown date for it.
The high-performance tier of the GLM-4.5 launch, tuned for throughput at the top of the range. The X suffix was retired as a naming convention after 4.5 - nothing in the 4.6, 4.7 or 5.x lines uses it - but the ids themselves are still served.
