Elon: try Grok 4.6 in the Grok Build harness or Cursor

Elon Musk says to try Grok 4.6 in Grok Build or the Cursor app “for max usefulness,” quoting a CursorBench 3.2 chart that puts Grok 4.6 Extra High first on score and far cheaper per task.
The quoted graphic puts Grok 4.6 Extra High at 70.8% task score and $2.81 per task, a hair above Fable 5 Max (70.5%, $17.32) and Opus 5 Max (70.0%, $8.23), with GPT-5.6 Sol Max at 67.2% and $5.69. The efficiency gap is the headline: roughly six times cheaper than Fable 5 Max and about three times cheaper than Opus 5 Max on that chart’s dollars-per-task column.
Elon’s own sentence is narrower than the chart. He did not write “Grok 4.6 is the best model.” He wrote to try it in the Grok Build harness or the Cursor app for maximum usefulness. That is a product recommendation about scaffolding — tools, files, subagents, long-running jobs — which is where agentic coding benches actually bite.
Claims vs measured
Measured, if the chart is honest: one harness, one leaderboard, one cost model. Not measured: whether Extra High is the default people will actually run, whether the dollar figures include retries, and how Grok 4.6 behaves outside CursorBench’s task mix. If you are deciding with money, run your own repo through both harnesses.
