Nous Research has shipped Bot Mode for Hermes Agent, its MIT-licensed open source agent. Bot Mode replaces the single-agent session list with a roster of named bots. Each bot is a real Hermes profile, with its own chat, memory, skills, and pinned model. Bots message each other through a persistent Agent Inbox and hand work off by @mention. The feature launched as a one-day public beta plugin from co-founder Teknium. It now ships bundled and default-on inside Hermes Desktop, in Hermes Agent v0.20.3.
Is it deployable?
Yes — today, on a desktop, at no license cost. Bot Mode shipped first as a one-day public beta plugin. It is now bundled and default-on inside Hermes Desktop, under Settings → Plugins. Both Hermes Agent and the plugin are MIT licensed.
Which companies: Solo builders, startups, and small-to-mid engineering teams can adopt it immediately. Enterprises should treat it as a workstation tool, not managed infrastructure. There is no admin console, no SSO, no central audit log, and no policy layer. Regulated buyers will need their own controls around it.
Industries: Software engineering, AI research labs, technical media and content operations, developer relations, quantitative research, and IT operations.
Applications: A research bot pinned to a reasoning model beside a writing bot on a cheaper one. Scheduled inbox digests and nightly reports. Per-project agents that never leak context into each other. Handoff chains where a scout, a reviewer, and a publisher pass work by @mention.
How it works under the hood
The interesting point here is that a bot is a Hermes profile. Each one lives under ~/.hermes/profiles/<name>/ with isolated config, memory, skills, credentials, and chat history. The plugin is a user interface over a primitive Hermes already shipped.
That choice keeps the surface area small. Creation and editing ride the profiles.* gateway RPCs: list, create, describe, configure. Avatar generation uses the image.generate RPC over local and remote gateways. Routines are ordinary Hermes cron jobs, namespaced [bot:<name>] <routine>. They still appear in hermes cron list.
Bot-to-bot messaging is the same story. Every bot has a persistent Agent Inbox conversation. Messages between bots are real CLI handoffs: hermes -p <bot> chat -c “Agent Inbox” -q “…”. They arrive with attribution, and each bot’s SOUL.md teaches the reply protocol. Typing @researcher have a look at this makes the active bot hand off and report back.
Configuration you actually get per bot
The New Agent dialog asks for name, title, and description. An Advanced disclosure opens the full profile config. You can clone an existing profile, pin a provider and model, write a custom SOUL.md, or skip skills. Right-clicking a bot exposes Edit Profile, which edits the live profile. That covers per-skill and per-toolset enablement, the model pin, and the SOUL.md. Duplicate clones config, skills, SOUL.md, memory, and appearance.
Avatars are geometric faces in seven shapes and ten colors. You can also upload an image, generate a portrait, or attach a pixel pet. The eyes scan while the bot works.
From one-day beta to bundled default
The rollout was fast. Teknium ran a one-day public beta through the standalone plugin and asked for bug reports. He committed to folding it into the main desktop app. That has now happened. Per hermes-agent PR #87886, Bot Mode is bundled and default-on, and the standalone repository is archived. Development continues in-tree at apps/desktop/src/plugins/hermes-bots/. The bundled plugin and its core teammate protocol landed in Hermes Agent v0.20.3.
The in-tree version added capability the beta did not have. Groups organise the roster into labeled sections that sync across machines. Group chats open a shared room for two to six bots. Your message triggers up to three serial rounds of member turns. Mentioned bots respond, everyone responds when nobody is mentioned, and each bot replies briefly or passes. A multi-source roster pulls bots from every connection under Settings → Connections.

Key Takeaways
- Bot Mode turns each Hermes profile into a named bot with its own chat, memory, and model.
- A bot is just a profile at ~/.hermes/profiles/<name>/ — no new storage layer.
- Bots message each other through real CLI handoffs into a persistent Agent Inbox.
- Group chats coordinate two to six bots over a maximum of three serial rounds.
- It shipped from one-day beta to bundled default-on Desktop plugin in Hermes Agent v0.20.3.
