David implemented pricing transparency for the Gemini 3.1 Flash Image Preview feature in the BerriAI/litellm repository, focusing on enabling customers to understand the financial implications of large-scale image preview processing. He developed a comprehensive pricing blueprint that detailed input and output costs, token usage, supported modalities, endpoints, and batch processing costs. Using skills in API development, API integration, and cost analysis, David structured the data model in JSON to ensure clarity and extensibility. His work provided a clear cost model that informs both customer decision-making and internal pricing strategy, demonstrating depth in both technical execution and domain understanding.
