Hermes Agent adds SuperGrok subscription support for xAI workflows
Nous Research added SuperGrok support to Hermes Agent, letting users plug a Grok subscription directly into the framework. It broadens Hermes beyond OpenAI runtimes and local setups into another mainstream agent model path.
TL;DR
- Nous Research said Hermes Agent now accepts a SuperGrok subscription, and Teknium separately confirmed users can plug that subscription into Hermes directly NousResearch's launch post and Teknium's confirmation.
- The official xAI announcement framed it as using a Grok subscription inside Hermes Agent, linking the rollout to xAI's own Grok-Hermes post NousResearch linking xAI's post.
- This moves Hermes further into mainstream hosted-model territory, not just local or OpenAI-style setups, as WesRoth's summary described it as connecting Grok to Nous's open-source agent framework.
- The Grok side of the stack is also getting more product surface, because koltregaskes on Grok Build and testingcatalog on Grok Build beta both tied Grok's coding workflow to skills, plugins, planning mode, and subagents.
You can read the short xAI announcement, browse the SuperGrok page, and the surrounding tweets make clear this is landing next to a broader Grok tooling push: Teknium's "Hermes Crew" post treated Grok as a new team member, while koltregaskes' pricing screenshot showed Grok Build features like parallel subagents, worktrees, hooks, and headless mode already bundled into SuperGrok Heavy.
SuperGrok inside Hermes Agent
Nous announced the change in a short post, then linked readers straight to xAI's own writeup.
Teknium's separate post made the product change plain: Hermes users can now authenticate with an existing SuperGrok subscription instead of treating Grok as an external workaround Teknium's confirmation. Later, Teknium followed with a "Hermes Crew" welcome that positioned Grok as another first-class model path inside the framework Teknium welcoming Grok.
A hosted Grok path for an open-source agent framework
The most concrete framing came from WesRoth's summary, which described the launch as wiring a Grok subscription into Nous's open-source, self-improving agent framework.
That matters mostly as product topology. Hermes already had an audience using custom setups, and this update gives xAI users a cleaner hosted route into the same agent shell. testingcatalog's post captured the pitch in one line: use Grok directly inside Hermes.
Grok Build shows what xAI wants that workflow to look like
The Hermes integration landed one day after xAI's Grok Build beta started circulating through the same crowd.
Across those posts, Grok Build was described with a familiar coding-agent feature set:
- plan mode with approvals and diffs koltregaskes on Grok Build
- AGENTS.md support, plus plugins and hooks koltregaskes on Grok Build
- parallel subagents in separate worktrees koltregaskes on Grok Build
- skills, subagents, plugins, and planning mode testingcatalog on Grok Build beta
- headless scripting and full ACP support for custom bots koltregaskes on Grok Build
That makes the Hermes announcement look less like a one-off partnership drop and more like xAI widening the places where Grok can act as an agent runtime.
Price and ecosystem clues
The catch is that the most fully featured Grok agent path still appears tied to SuperGrok Heavy pricing. koltregaskes' pricing screenshot showed Grok Build listed under a $300 per month tier, with a three-day trial mentioned in the same thread.
That last thread also surfaced another ecosystem detail: mr_r0b0t asking for ACP support said Hermes was already "ACP ready" and asked Zed for formal support, after separately showing Hermes running Grok 4.3 on local NVIDIA DGX Spark hardware mr_r0b0t running Grok 4.3 in Hermes. The interesting part is not just that Grok now works in Hermes, but that Hermes is being pushed simultaneously toward hosted subscriptions, ACP wiring, and local hardware demos.
