Closes #102312
What Problem This Solves
OpenClaw's bundled xAI catalog does not expose Grok 4.5, so users cannot select xAI's current flagship model through the normal provider and model flows.
Why This Change Was Made
This adds Grok 4.5's static and dynamic model metadata, official aliases, reasoning compatibility, live-model coverage, and regression tests. It keeps Grok 4.3 as the setup default because xAI currently limits Grok 4.5 availability by region; supported users can explicitly select
xai/grok-4.5.The docs now describe Grok 4.5 selection, aliases, thinking levels, pricing, context limits, and the regional-safe default.
User Impact
Users in supported regions can select
xai/grok-4.5and uselow,medium, orhighthinking levels. Existing xAI setup and default-model behavior remain unchanged.Evidence
