Mercury Edit 2 is a diffusion language model (dLLM) from Inception that succeeds the company's previous next-edit model. Inception bills it as a next-edit diffusion LLM built for the speed-critical parts of coding, saying it generates tokens in parallel so edit suggestions arrive quickly. The model is made for code editing, predicting a developer's next change from recent edit history and codebase context.
