From the column inspection, I can see several numeric measures: 'Best score (across scorers)' (DOUBLE, range 0.0-1.0), and several token-related measures (billable_input_tokens, billable_output_tokens, cache_read_tokens, cache_write_tokens) which appear to be VARCHAR but might contain numeric data. I also see from the card that there are additional measures like Parameters, Training compute (FLOP), Citations, etc. that weren't in the first 30 columns. Let me inspect all columns to see the full set of numeric measures.",
