Nous Research has launched a playful new feature for Hermes Agent, introducing animated pets that enhance user experience without impacting performance.
Nous Research Introduces Playful Mascots to Hermes Agent
Nous Research has launched a feature for its Hermes Agent that allows users to enjoy over 3,200 animated mascot sprites. These animated pets, although purely decorative, respond to the agent's actions in six distinct states: idle, running, thinking, waving, celebrating, and failing. Importantly, they do not affect any operational aspects such as tokens or caching.
The new feature is accessible via the command-line interface (CLI), text user interface (TUI), and desktop application. Users can opt to display their chosen pet in a floating window, which remains visible during interaction with the agent.
The animated sprites are sourced from petdex, an open-source repository that hosts a wide array of mascot designs. Users can easily install a pet using the command hermes pets install boba --select. This feature is disabled by default, requiring users to activate it manually.
Switching between pets is straightforward with the command hermes pets select name. The rendering of these mascots is compatible with various graphical protocols, allowing for high-quality displays in supported terminals. If not, the sprites will still appear in a lower resolution, reminiscent of early digital graphics.
In the desktop version of Hermes Agent, the mascot can float on a canvas, and users can detach it into a transparent window that stays on top of other applications. This window displays messages such as "working..." and "your turn", adding a whimsical element to the user experience without any expectation of utility, avoiding the pitfalls of similar features like Clippy.
Nous Research has emphasized that these pets are purely for aesthetic enhancement and do not influence the agent's performance. Introduced in February 2026, Hermes Agent has gained significant traction, amassing over 180,000 stars on GitHub, along with a suite of robust features, including persistent memory and multi-agent support. The pet feature was subtly introduced alongside other functionalities, highlighting the ongoing development of the Hermes ecosystem.
