To address the query about the best prompts and test cases to evaluate Grok 4's multimodal reasoning capabilities comprehensively, I gathered diverse information from recent sources and research literature on multimodal reasoning evaluation, prompt engineering, and specific insights into Grok 4's performance and benchmark tests.

Overview of Multimodal Reasoning Evaluation
Multimodal reasoning involves understanding and integrating information from different modalities such as text, images, and sometimes other data types (e.g., audio) to produce coherent and accurate outputs. Effective evaluation of such models requires prompts and test cases that not only assess correctness but also the ability to reason across modalities, handle complex tasks, and align reasoning chains with human-like logic.
Key points in designing multimodal reasoning evaluation are:
- Creating prompts that span multiple modalities simultaneously (e.g., images with contextual text).
- Including tasks of varying complexity to probe the model's reasoning depth.
- Using example prompts that balance easy and hard challenges to evaluate performance across the complexity spectrum.
- Evaluating not just final answers but also the rationales behind them to verify the model's understanding of how different modalities influence the decision-making process.

Best Practices for Crafting Multimodal Prompts
From recent AI research and practical systems built to optimize prompt engineering, including interactive tools for prompt refinement (e.g., POEM system), several best practices emerge:
1. Contextual Richness and Clarity
Prompts should provide enough context in both textual and visual components to avoid ambiguity and enable the model to make accurate inferences. They need to sound natural and cover nuanced aspects that require complex reasoning rather than straightforward recognition.
2. Comparative and Analytical Reasoning
Some prompts should explicitly involve tasks where multiple modalities provide complementary or conflicting information. This tests the model's capacity to weigh evidence, prioritize modalities, and synthesize answers accordingly.
3. Diverse and Balanced Difficulty Levels
Using a curriculum-inspired approach, prompts should include a well-ordered set of examples from simple to complex problems, tailored to the model's current knowledge capacity. Too many simple or too many difficult prompts skew results and limit learning insights.
4. Chain-of-Thought (CoT) and Multimodal Chain-of-Thought (MCoT)
Prompts encouraging explicit step-by-step reasoning that integrates information across modalities improve transparency and make evaluation more granular. MCoT prompts guide the model to explain its reasoning involving both image and text data.

Specific Test Cases and Prompt Examples for Grok 4
Grok 4, as a cutting-edge multimodal model with reported strengths in coding, writing, and image analysis tasks, benefits from test cases designed to reflect these capabilities with a multimodal twist.
Coding and Analytical Reasoning with Multimodal Context
- Provide Grok 4 with code snippets or debugging scenarios combined with graphical data (e.g., function execution graphs or UML diagrams) and ask for:- Explanation of bugs using both code and diagrams.
- Generation of code snippets solving problems visualized in charts.
- Example prompt: "Given this function flowchart and the code below, identify the logical flaw and propose a fix, explaining how the diagrams guided your reasoning."
Visual Understanding and Integration Tests
- Present images with embedded textual information (e.g., product labels, scientific diagrams) and ask Grok 4 to:- Extract, interpret, and summarize the combined information.
- Make inferences requiring cross-reference (e.g., "Analyze this image of a water bottle with nutritional facts and answer: How does the content compare with daily recommended intake?").
- The water bottle image analysis test yielded Grok 4's highest recorded score, illustrating the value of combined information prompts.
Complex Multimodal Reasoning and Grounding
- Create scenarios where the model must reconcile contradictory information from multiple modalities and explain its reconciliation process.- Example: "Look at this photo of a plant species alongside textual traits common to two similar species. Identify the species and justify your conclusion by referencing image details and textual traits."
Multimodal SQL and Data Query Generation
- Employ financial or business datasets with charts and tables and pose complex natural language queries requiring Grok 4 to generate and explain SQL queries that simultaneously leverage visual and textual contextual cues.Scientific and Technical Domains
- Use multimodal prompts combining chemical structure images, reaction pathways, and experimental notes to test Grok 4's ability to design plausible synthetic routes or analyze conflicting pathway data while respecting safety and ethical guidelines.***
Systematic Evaluation Frameworks
To robustly evaluate Grok 4, leveraging systems such as EvaluateGPT for domain-specific prompt evaluation combined with human or expert LLM raters provides a reliable method to gauge the model's multimodal reasoning. Evaluation should cover:
- Correctness and Accuracy: Does the model produce valid, precise answers respecting multimodal input?
- Reasoning and Explanation Quality: Are the reasoning steps consistent with the data from all modalities?
- Adaptability and Robustness: How well does the model handle variations in input quality or modality conflicts?
- Efficiency and Usability: Time taken and ease of extending the model's multimodal capabilities in real-world applications.

Summary of Effective Prompting Strategies
- Use multi-level and multi-faceted prompts that test global understanding and fine-grained modality interactions.
- Facilitate comparative prompt analyses by varying structure, content, and demonstration examples to optimize reasoning.
- Prioritize balanced difficulty prompts with a mix of straightforward and highly complex queries.
- Encourage explicit chain-of-thought reasoning that spans multiple data modalities.
- Include domain-specific, real-world inspired challenges that align with Grok 4's strong suits, such as finance, coding, and scientific research.
