LLM moderation costs: Prioritize token counting and JSON output for budget efficiency

To manage costs in LLM-based moderation, developers should first estimate the token count of their prompts before selecting a model. This approach prioritizes prompt efficiency over raw model power, as lengthy policy rubrics can significantly increase costs. Accurate token counting, especially for non-English text or complex data like URLs and emojis, is crucial to avoid unexpected expenses from retries due to unparseable outputs. For image moderation, the cost is calculated differently based on image dimensions, and downscaling may be a viable cost-saving measure. AI

IMPACT Optimizing LLM prompt design and token usage can significantly reduce operational costs for AI-powered moderation services.

RANK_REASON The item discusses a technical implementation detail for using LLMs in a product context, focusing on cost optimization rather than a new release or research.
