Finding · P60 · Author-curated
On arithmetic probes with bare numbers, pooled over five tasks and two instruction languages, Bielik-PL-11B-v3.0-Instruct answers 0.8582 of 5,000 items correctly and Bielik-11B-v3.0-Instruct 0.8428.

Relation: Metric comparison
- metric
- Arithmetic probe accuracyQuantity compared.
- subject
- Bielik-PL-11B-v3.0-InstructModel after the tokenizer change.
- subject value
- 0.8582 share of itemsValue of the metric for the subject.
- comparator
- Bielik-11B-v3.0-InstructModel before the tokenizer change.
- comparator value
- 0.8428 share of itemsValue of the metric for the comparator.
- setting
- Bare number formatNumber format of the items.
- scope
- 5,000 items per model: 500 per task for addition, subtraction, comparison, sorting and unit conversion, each with English and Polish instructions; all digit lengthsItems pooled.
Experimental provenance
- Method and evaluation protocol
- Greedy generation with at most 256 tokens; dual-locale grading of the last number in the answer; per-cell counts pooled over tasks and instruction languages.
- Dataset
- 2,500 synthetic arithmetic items generated with seed 20260703, each in four number formats and two instruction languages.Version: unspecified · Access: public
- Reported results
- 0.8582 against 0.8428; truncated answers 0 and 0; answers ambiguous between the English and Polish readings 4 and 3; answers without a number 0 and 0.
- Uncertainty and replication
- Point values over 5,000 items per model; per-cell Wilson intervals are in results/probe_results.json.

- Limitations
- The two models differ by 20B tokens of continued pretraining and by post-training as well as by the tokenizer; answer-only probes do not measure chain-of-thought arithmetic; MLX bf16 numerics differ from the paper's evaluation stack.

Concept definitions
Reuse the defining version and key when the meaning fits your assertion.
Metric comparison
The subject and the comparator take subject_value and comparator_value of the metric; benchmark, scope, evaluation_text, language and setting state what the values were measured on, where given. Values may come from separate evaluation runs.
