The Best LLMs For Hermes Agent, Ranked By Real Work
By Julian Goldie · 2026-07-20 · GoldieBench Blog
Hermes Agent takes any brain: cloud frontier models via API or subscription CLIs, free API tiers, or fully local models through Ollama.
We run all three lanes daily and benchmark everything on the same 45 builds.
Here's the honest ranking.
Tier 1 — frontier brains for the hard 10%
Claude Opus 4.8 and GPT-5.6 sit at the top of the main board — these are the planners you want steering long multi-step jobs.
GLM 5.2 is the value pick: near-frontier agentic performance, and its coding plan is dramatically cheaper.

Tier 2 — free API brains
OmniRoute-style free routers give you dozens of models at $0 with tool support.
Great for drafts and batch work; latency and rate limits make them a poor fit for interactive loops.
Tier 3 — local brains (free forever)
The local leaderboard settles this with data: Qwable 5 27B for build quality (7.14), Agents-A1 for agent work at 95 tok/s (4.83, agent-tuned for tool calling), Gemma 4 12B MLX as the lightweight workhorse (3.98, .62 tok/s).
The routing that actually works
Don't pick one — route.
Main model: your strongest CLI subscription (Claude or GPT-5.6, already paid for).
Sub-agents: a local model for auxiliary tasks.
Fallback: GLM or a free router when the primary is down.
Hermes profiles make each a one-line switch, and the whole pattern is wired into the Agent OS so swapping brains never changes your workflow.
FAQ
What's the single best LLM for Hermes Agent?
If you have a Claude subscription, Claude Opus-class models as the main brain. If you want $0, Agents-A1 locally. Most users should route: frontier main model + local sub-agent.
Is GLM 5.2 good enough for Hermes?
Yes — it's our budget primary for build tasks and the engine behind several Agent OS pipelines. It occasionally truncates long outputs, so keep a fallback in the chain.
Do local models support tool calling for agents?
The agent-tuned ones do it best — Agents-A1 was trained specifically for long-horizon tool work (its vendor claims SOTA on IFBench instruction following). Smaller instruct models manage simple tools but drop complex schemas.
Where do these rankings come from?
GoldieBench: the same 45 one-shot builds for every model, rendered and scored 0–10 by an Opus vision judge, with every demo playable on this site.
