xAI released Grok 4.7 on September 21 at 2.1 trillion parameters, a 40% jump over Grok 4.6's 1.5T, with a 500K context window and unchanged pricing of $2/$6 per million input/output tokens. It scores 46.3% on CursorBench 4.0 (up from 40.4%), 71.0% on DeepSWE v1.1 at high effort (up from 65.2%), 64.0% on EEBench and 19.6% on Harvey Legal Agent. GitHub began rolling it into Copilot across Pro, Pro+, Max, Business and Enterprise the same day, and Artificial Analysis puts it at the same composite 46 as Xiaomi's open-weight MiMo-V2.6-Pro, which charges roughly a fifth as much per token.
