GraphBit: DAG-Based Agent Orchestration Beats Six Frameworks with Zero Hallucinations on GAIA

arXiv·high signal

GraphBit is an engine-orchestrated agentic framework that defines workflows as deterministic directed acyclic graphs with a Rust-based execution engine. On the GAIA benchmark, it achieves 67.6% accuracy with 0% framework-induced hallucinations, outperforming LangChain, LangGraph, CrewAI, AutoGen, Pydantic AI, and LlamaIndex by 14.7 percentage points. Three-tier memory architecture (ephemeral scratch, structured state, external connectors) prevents context bloat, with only 11.9ms overhead per execution step.
