Speculation Swirls Around Cursor Launch and xAI Models

A reply from @teortaxesTex questioned why Cursor would attempt a stealth launch, citing its Musk ties, ample PR resources, and focus on post-training for agentic software engineering. Another from @andersonbcdefg assumed xAI now directs all effort to Grok models and would not allow separate post-trained Chinese lines. Both posts treat these as assumptions rather than confirmed developments, with no first-party statements or independent corroboration present in the packet.
