Grok Build 0.1 on API

xAI released Grok Build 0.1 in public beta through the xAI API for agentic coding tasks, with throughput above 100 tokens per second and pricing at $1 per million input tokens and $2 per million output tokens.

Why it matters: HKR-H/K/R all pass, but this is a 0.1 public-beta API and pricing launch; benchmarks, context window, and task success rates are not disclosed. It fits a solid mid-weight product update at 78, featured not p1.
