Hermes Agent crosses 140,000 GitHub stars in under three months, takes the OpenRouter top spot
Self-improving open-source agent project is now the most-used agent in the world by OpenRouter's tracking, according to NVIDIA, which is highlighting Hermes as the agentic showcase for its RTX and DGX Spark consumer hardware.
Hermes Agent has crossed 140,000 GitHub stars in fewer than three months and is now the most-used agent in the world by OpenRouter’s tracking, NVIDIA said in a post tied to its RTX AI Garage program.
NVIDIA’s framing is product-shaped — Hermes runs on RTX PCs and on DGX Spark, the consumer-class Spark hardware NVIDIA has positioned as the on-desk agentic dev box — but the underlying community signal is real. Hermes’s growth curve sits well outside the normal range for an open-source agent framework. By comparison, the largest framework of the prior generation, LangGraph, took multiple years to reach a comparable star count.
What Hermes calls “self-improving” is, in mechanical terms, an agent loop that proposes its own subagents and tool configurations rather than asking the operator to wire them up by hand. The framing has drawn predictable skepticism in alignment-research circles; the operator-facing pitch is that the loop converges on something that works for the specific task at hand, rather than requiring up-front orchestration design.
The OpenRouter metric — “most-used agent in the world” — is usage-weighted and proxy for production attention rather than star count. NVIDIA cited it directly; OpenRouter did not respond to a request to share the underlying numbers.
What to watch over the next month: whether Hermes-built workflows show up in production at companies that aren’t running RTX or Spark hardware. The star count signals developer interest. The deployment graph is the harder number, and the one that decides whether Hermes is a moment or a fixture.
