Gemini 2.0 Flash Think Exp Old (Lech Mazur leaderboard source label)

Lech Mazur Benchmarks

Gemini 2.0 Flash Think Exp Old is the exact source label for a separate model-like entry in the STEP Game leaderboard; the repository logs identify it as `gemini_20_flash_thinking_exp`, while a later checkpoint appears separately as `gemini_20_flash_thinking_exp_0121`. The source does not expose the API model identifier for the old entry, so it cannot be mapped unambiguously to Google’s dated `gemini-2.0-flash-thinking-exp-1219` checkpoint or its mutable undated alias.
