Common Pitfalls to Avoid

Underutilizing Multimodal Capabilities

Don't limit yourself to text-only interactions when Qwen can process multiple input types simultaneously.

Insufficient Context for Complex Tasks

Qwen's capabilities scale with the quality and completeness of context provided.

Ignoring Language Diversity

Take advantage of Qwen's 119-language support for truly global applications.

Overlooking Agent Capabilities

Don't treat Qwen as just a question-answering system; leverage its ability to execute complex, multi-step workflows.

Generic Prompting

Avoid one-size-fits-all prompts; tailor your approach to Qwen's specific strengths and capabilities.

Troubleshooting

Inconsistent Multimodal Results

• Ensure file formats are supported and clearly referenced
• Provide explicit instructions for how different media types should be processed
• Test with simpler multimodal combinations before complex scenarios

Language Processing Issues

• Specify the primary language for analysis when working with multilingual content
• Provide cultural context when language nuances are important
• Test language-specific prompts with native speakers when possible

Agent Task Failures

• Break complex workflows into smaller, testable components
• Provide clear success criteria for each step
• Include error handling instructions for common failure scenarios

Performance Optimization

• Monitor response times and adjust prompt complexity accordingly
• Use appropriate model sizes for different task types
• Consider batch processing for large-scale analysis tasks

    def execute_workflow(self, workflow_steps):
        results = {}
        for step in workflow_steps:
            prompt = self.build_step_prompt(step, results)
            response = self.call_qwen(prompt)
            results[step['name']] = response
            self.conversation_history.append((prompt, response))
        return results
    
    def build_step_prompt(self, step, previous_results):
        context = f"Previous results: {previous_results}\n"
