# First Divergent Token metric rollouts on GGUF and MLX quants > Still true after a fresh search: no FDT measurement on any GGUF or MLX quant of one BF16 base on Apple silicon was found in the search results for "first divergent token quantization GGUF MLX rollout" (results were MLX-vs-GGUF speed posts).
