JSON vs. XML: A Data-Driven Analysis of LLM Parsing Efficiency
I had a question about LLM format performance. So I tested it — 12 models, 8 companies, 120 runs, automated scoring. Format preference turns out to be architectural: Anthropic prefers XML (+30%), Kimi and Google prefer JSON, Grok is format-agnostic.

Writing History on Chain: Announcing SIMULACRA: Genesis
My next project is not a tool, it's a universe. Introducing SIMULACRA: Genesis, a persistent on-chain simulation where player actions create a permanent, canonical history for a world yet to be explored.
JSON vs. XML: A Data-Driven Analysis of LLM Parsing Efficiency
We tested 12 major LLMs across 8 companies. A definitive, data-driven analysis reveals that format preference is dictated by a model's underlying architecture, not a universal rule.
