4. Accuracy Benchmark Comparison
Both builds were evaluated with the same prompts and chat template. The reference was run on an A800 in
BF16. All accuracy benchmarks were run with the EvalScope evaluation framework.

- IFEval (Prompt Strict): Measures a model's ability to strictly comply with verifiable
formatting, structural, and language constraints in prompts (all rules must be met).
- BFCL v4 (Multi-turn Base): Evaluates function-calling (tool use) capabilities across
multi-turn conversational interactions, testing tool selection, parameter accuracy, and context
maintenance.
- MMLU-Pro: Benchmarks advanced multi-step reasoning and domain expertise across 14
academic/professional subjects using rigorous 10-choice questions.
- Needle in a Haystack: Evaluates long-context information retrieval by testing if a
model can find a specific target fact hidden inside a massive block of irrelevant context.
- HumanEval+: Measures Python code synthesis correctness using an expanded, heavily
augmented test suite to prevent false positives.
Reproducibility: Results are comparable only under matching test conditions. Reproducing
these results requires the same model version, evaluation setup, prompts, dataset split, and scoring
method.
