grok-code-fast-1 is free (for a limited time) in opencode zen, has been for a while. (Originally it was billed as a test/to gather training data for xAI.) But right now GLM 4.6 is also temporarily free there (hosted by opencode themselves; they call it "big pickle", and there's no data collection), has been for weeks, and GLM 4.6 is far better (better than Haiku and not very far off Sonnet), and still very fast, so I have no use for gcf1 anymore.
