Sarcasm counts as its meaning. Posts by MiniMax (@MiniMax_AI, @MiniMaxAgent) or MiniMax staff (@Ronny_MiniMax, @RyanLeeMiniMax, @olive_jy_song, @RenLeanna), and partner/vendor accounts announcing availability or promoting access on their own platform (OpenRouter, Vercel, TokenRouter, Qoder, B.AI and @justinsuntron, LLM Gateway/@smakosh, Merge) are \"neutral\" and flagged `from_minimax_or_partner: true`, and are left out of the counts. When unsure between two labels, choose the less extreme (mixed over negative/positive; neutral over mixed).
