Cursor joins The X Subscription, with paid plans offering twice the Grok coding usage of equivalent Cursor plans

#1 𝕏

Cursor announced that it is now included in The X Subscription, with paid plans sharing one usage pool across Cursor, Grok Build, and other Grok products and offering twice the coding usage on Grok models versus equivalent Cursor plans. Existing subscribers can keep their plans or switch; Premium, Super, and Ultra include Grok Bot, while third-party Cursor models move to API pricing under the new plans.

QwenGyre was announced as an elastic RL system for extreme-long-horizon agent training with two core designs: an Elastic Scheduler that reallocates GPUs between rollout and training, reporting up to 1.85× speedup over Colocate and 1.78× over Async, and a Trajectory Processor that converts branching executions into prefix-shared trajectory trees with bounded, deduplicated training samples. Scaled to Qwen3.8-2.4T-A95B with ~700K tokens per rollout, it increased NL2RepoBench from 52.5% to 58.5% in 48 steps while reducing end-to-end training time by ~44% versus Async.
