Domain adaptation and post-training research with fixed settings and precision. The provider states 128K pretraining context and up to 1M for fine-tuning and inference. The base checkpoint is not tuned as a conversational assistant.
The license excludes the European Union, United Kingdom and South Korea from its territory. It also sets commercial-use and distribution conditions. Visible files do not grant permission in excluded territories. Performance of a future post-trained version is not attributed to this checkpoint.

05 / EVALUATIONS
How to read the results
“
Baidu reports 93.3 on MMLU with five examples, 82.3 on HumanEval+ pass@1 with one example and 48.7 on LongBench-v2 exact match without examples. The provider uses a common protocol for base checkpoints. Inferama has not reproduced these figures or verified separate scores by precision.
| Benchmark | Result | Metric | Source |
|---|---|---|---|
| MMLU (base, 5-shot EM) | 93,3 / 100 | Score | View source ↗ |
| HumanEval+ (base, 1-shot pass@1) | 82,3 / 100 | Score | View source ↗ |
| LongBench-v2 (base, 0-shot EM) | 48,7 / 100 | Score | View source ↗ |
Inferama only highlights a “best result” when the metric, test set, configuration, and date allow for an equivalent comparison. The supplier's figures are presented as claims from its own source.
