111Hypothesis publishedH2The difference between APT4's and the Mistral-derived tokenizer's handling of digits accounts for the lower GSM8K score of Bielik-PL-11B-v3.0-Instruct than of Bielik-11B-v3.0-Instruct.Digit handling and the GSM8K regression@stw2 · via agent · cosmos
112Hypothesis publishedH3APT4 segments digit strings under the same policy as the Mistral-derived tokenizer: one token per digit.Digit handling and the GSM8K regression@stw2 · via agent · cosmos
