Just as OpenClaw found itself beleaguered on all sides, Hermes Agent made its quiet yet powerful debut. Open-sourced in late February 2026 by the Silicon Valley-based team Nous Research, this AI Agent project leveraged a fundamentally different design philosophy to overtake OpenClaw in a remarkably short span of time.
Differentiator 1: From "Resetting upon Completion" to "Growing Smarter with Use"
OpenClaw’s memory architecture has long been a major pain point for developers: at the end of each session, the Agent's memory virtually resets to zero, failing to retain any accumulated experience or user preferences for the next run. In contrast, Hermes’ core design philosophy is encapsulated in its slogan—“the agent that grows with you.” It features a built-in, self-evolving learning loop: upon completing a complex task, the Agent automatically analyzes its execution trajectory, identifies high-frequency operational patterns, and encapsulates successful experiences into structured "Skill" files stored in the user's local repository. When a task triggers specific criteria—such as invoking tools more than 5 times, self-healing after a mid-way error, or incorporating explicit user corrections—it automatically generates a reusable skill for future, similar tasks to invoke directly. Empirical tests show that after 3 months of continuous operation, 65% of new tasks can directly leverage existing skills, yielding measurable improvements in both execution efficiency and accuracy.
Differentiator 2: Persistent Memory for Cross-Platform Continuity of User Preferences
Hermes is powered by a persistent architecture known as the "Three-Tier Memory System": Working Memory handles the current session context, Episodic Memory stores historical sessions for retrieval, and Procedural Memory solidifies the operational patterns the Agent has mastered. Crucially, this memory system retains continuity across platforms and devices. A user's preferred terminology and command style on WeChat will be seamlessly carried over to Feishu (Lark) or Telegram by the exact same underlying memory layer, eliminating the need for repetitive training.
Differentiator 3. Security First: Guarding the Baseline of Data Privacy
In stark contrast to the trust crisis OpenClaw faced due to security vulnerabilities, Hermes took an entirely different path in its security design. With zero-telemetry by default, automated masking of confidential information, and default rejection of stranger messages on WhatsApp, these design choices are highly compelling for enterprise and domestic users operating under increasingly stringent data sovereignty and privacy compliance mandates. To date, the number of documented CVE vulnerabilities for Hermes Agent stands at a clean zero—a safety record exceedingly rare among open-source intelligent agents.
These distinct advantages translated directly into community acclaim and market validation. Hermes hit 40,000 GitHub Stars in just 45 days from its launch, eclipsing OpenClaw’s 61-day timeline. By mid-May, that figure shattered 135,000 stars, sporting an MIT license and shipping with over 40 out-of-the-box Skill modules. On OpenRouter’s daily token volume charts, Hermes officially dethroned OpenClaw on May 11, claiming the global top spot with a staggering 271 billion tokens consumed daily.
More importantly, Hermes unlocked its own "commercial accelerator." Mainstream model providers such as Xiaomi, NVIDIA, and StepFun have aggressively integrated the Hermes Agent framework into their ecosystems. Among them, Xiaomi’s MiMo alone contributed a massive 1.45 trillion tokens to Hermes within a single month. In tandem, Xiaomi launched a 100-trillion-token incentive program and an Agent Ecosystem Co-construction Initiative tailored for global AI users, deep-linking its operations with top-tier frameworks like Hermes Agent. This has catalyzed a powerful flywheel effect: a more active community drives larger token volumes; larger token volumes incentivize model vendors to hook into the ecosystem; and a more prosperous ecosystem drastically lowers the barrier to entry for end users.
Naturally, Hermes is not without its imperfections. As the skill repository swells and tasks scale in complexity, the retrieval efficiency of its memory system will inevitably face friction. Some developers have noted in real-world testing that if the path initially taught to the Agent is flawed, the skill file will "learn" the incorrect methodology, causing performance to drift progressively off-course. Correcting "mislearned habits" proves far more challenging than training an agent from scratch, placing higher demands on Hermes’ skill validation and error-correction mechanics. Furthermore, skeptics argue that its meteoric rise carries distinct hallmarks of a "manufactured blockbuster"—its WeChat Index and Baidu Index display a steep growth curve almost identical to OpenClaw’s historical data. While this logic of "engineered hype" may hold water commercially, whether it can truly translate into long-term user retention remains to be seen through the lens of time.

Stars and token throughput are easy to game and don't really tell you which one handles the workflows people run day to day. The differentiators you mentioned (persistent skills, three-tier memory, zero-telemetry default) are what I'd want actual benchmarks on. Has anyone done a head to head on a 20 task suite where both stacks have to remember prior outcomes across sessions? That's the harder number to fake, and the one I haven't seen yet. Worth flagging that "mis-learned habits" isn't unique to skill files either. Any agent that writes to its own context tail picks up the same drift, just less visibly.
