NousResearch Ships Hermes Agent 0.20 Five Months After 0.2 — r/LocalLLaMA Asks If Open Agents Can Reach Omni-Model Parity

A 123-upvote post notes NousResearch has iterated Hermes from version 0.2 in mid-March to 0.20 by Q3 2026, and uses the pace as a jumping-off point for a broader question: can an open agent stack reach the strength of a true end-to-end omni model like GPT-omni or Personaplex? The nostalgia framing in the thread — remembering llama 1/2-era function-caller parsers held together with LangChain — is itself the datapoint about how fast open tool-calling matured. Single-source community discussion with no benchmark comparison attached, so treat the parity question as open.
