Evaluating LLM Benchmarks with Pulsar

MMLU multiverse analysis reveals hidden structure

100 representations fused into a cosmic graph reveal 15 topological regions, near-pure semantic islands, and model-specific failure zones that single-number leaderboards miss.

Pulsar: Robust Topology at Scale

From peer-reviewed research to open-source tool

Pulsar brings the Thema algorithm from our Nature Energy paper to everyone. High-performance Rust implementation with MCP integration for AI-assisted topological data analysis.
