Hermes Agent supports X Premium+ login with Grok 4.3 and X Search
Nous Research expanded Hermes Agent so X Premium+ and SuperGrok logins can unlock Grok 4.3, X Search, and media tools without separate keys. Bookmarks and full X API access still sit outside the OAuth path.

TL;DR
- NousResearch's announcement says Hermes Agent now accepts X Premium+ logins, expanding the earlier SuperGrok integration beyond direct Grok subscribers.
- According to Teknium's feature summary, the OAuth path can unlock Grok access, X Search, image generation, video generation, and voice inside Hermes, without a separate xAI API key.
- altryne's walkthrough says the OAuth route is still narrower than full X API access, and explicitly excludes things like bookmarks.
- The most interesting addition is the server-side
x_searchtool that NousResearch's docs link and testingcatalog's screenshot describe as a Grok-backed search path for posts, profiles, and threads with synthesized results and citations. - A separate SuperGrok Heavy pricing screenshot still shows Grok Build behind a $300 per month tier, which keeps Hermes's OAuth expansion distinct from xAI's own premium CLI packaging.
Docs and demos
The official xAI announcement, the Hermes Grok OAuth guide, and the Hermes X Search docs sketch out the same picture the tweets do: Hermes is turning subscriptions into agent access, not just model access. You can also see Teknium's screenshots showing grok-4.3 in the model picker, while NousResearch's launch clip framed the first step as SuperGrok support a day earlier.
OAuth access
The rollout happened in two steps. NousResearch's May 15 post and Teknium's confirmation first added SuperGrok logins, then NousResearch's May 16 update expanded that path to X Premium+ subscribers too.
That matters because Hermes is using account login as a provider surface. Teknium's provider menu screenshot shows XAI Grok OAuth sitting alongside direct API providers, local tools, and other OAuth-backed options, and dingyi's post linking the setup guide confirms the flow is exposed as a documented feature rather than a one-off demo.
X Search
The X hook is more than model routing. NousResearch's X Search post points to docs for an x_search tool, and testingcatalog's documentation screenshot captures the core behavior: search posts, profiles, and threads directly, run the search server-side through xAI's Responses API, and return synthesized results with citations.
altryne's screenshot usefully separates this from a logged-in X client. The examples in that image frame x_search as public semantic search for questions like:
- what people are saying about Hermes
- latest xAI posts about X Search
- reactions to a launch
- @karpathy posts about evals
- the thread where someone said a specific thing
- topic monitoring
- research digests from public X
Limits
The OAuth package is broad, but not total. Teknium's summary lists Grok, X Search, image generation, video generation, and voice, while altryne's walkthrough says bookmarks and other full X API capabilities still require an API key.
That creates a clean split inside Hermes:
- subscription OAuth for bundled consumer features
- API credentials for deeper platform access
- public X search through Grok's server-side tool
SuperGrok Heavy
One extra detail sitting adjacent to this rollout is pricing. koltregaskes's screenshot shows xAI's own SuperGrok Heavy tier advertising Grok Build, parallel subagents and worktrees, smarter planning and self-review, plus MCP, skills, plugins, hooks, and headless mode for CI/CD.
That makes Hermes's expansion notable in a different way. mattlam_'s Grok CLI screenshot shows xAI building its own agentic CLI stack, but Hermes is using subscription login to expose Grok 4.3 and X-native search inside a separate open-source agent framework instead.
