InternVL3.5: Advancing Open-Source Multimodal Models in Versatility, Reasoning, and Efficiency — Wang et al. (2025) (arXiv:2508.18265, 2025)

What this evaluates

Evaluates multimodal large language models across general understanding, complex reasoning, mathematics, OCR, document comprehension, and agentic/GUI interaction tasks.

Datasets

• MMMU — total ?; splits: val (-1)
• MathVista — total ?; splits: mini (-1)
• MMStar — total ?; splits: test (-1)
• MMVet — total ?; splits: test (-1)

Metrics

• accuracy (primary) — range: percent
  • Percentage of correctly predicted answers out of the total number of instances. Calculated as (correct predictions / total instances) * 100. For benchmarks like MMVet, scores are derived via LLM-as-judge evaluation.

Input / output format

Input: Image or video frames paired with a text prompt/question. For agentic tasks, GUI screenshots or environment states with action instructions.

Output: Text response containing the final answer, reasoning steps, or action sequence.

Scoring recipe

def calculate_accuracy(predictions, gold):
    correct = sum(1 for p, g in zip(predictions, gold) if normalize_answer(p) == g)
    return (correct / len(gold)) * 100

# For LLM-as-judge benchmarks (e.g., MMVet):
# score = llm_judge.evaluate(predictions, gold, prompt_template=judge_prompt)
# return score

Common pitfalls

• Benchmark versions vary significantly (e.g., MMBench V1.1 vs V2.0); results are not directly comparable without specifying the exact version.
• MMVet relies on LLM-as-judge scoring, which is highly sensitive to the judge model, version, and prompt template used.
• Agentic benchmarks (e.g., OSWorld-G, ScreenSpot) require interactive environment execution, not just static QA generation.

Evidence (verbatim from paper)

To comprehensively evaluate the multimodal reasoning and mathematical capabilities of InternVL3.5, we conduct extensive experiments across a series of benchmarks, including MMMU for multidisciplinary reasoning, MathVista, MathVision, and MathVerse for mathematical reasoning... The overall score is the average score of all benchmarks.
