This interactive scatter plot compares the cost of API calls against web development performance scores for various large language models. Each circle represents a model, colored by provider (OpenAI, Anthropic, Google, or Other), with cross-hair lines and a dashed trend line revealing the cost-performance trade-off. Hovering over a provider in the legend highlights that provider’s models. Built with React, D3.js 7, and SVG, it reads pricing data from OpenRouter and performance benchmarks from LMArena.
