If you’ve been following the open-source AI agent scene, you probably just saw the leaderboard flip. It’s a pretty big deal.
As of May 10th, 2026, Nous Research’s Hermes Agent has officially bumped OpenClaw from the #1 spot on OpenRouter’s daily rankings. We’re talking 224 billion daily tokens for Hermes versus OpenClaw’s 186 billion. That’s a massive amount of activity, and it makes Hermes the most-used open-source agent on the planet right now by that metric.
But this isn’t just about numbers on a chart. This is a story about two completely different ideas of what an AI agent should be. It’s a classic tale of reach versus intelligence, and it looks like the community is starting to pick a side.
Two Agents, Two Totally Different Philosophies
So, what’s the actual difference between these two? It really comes down to their core design.
Think of OpenClaw as the ultimate social butterfly. Its entire structure is built around a central gateway that connects to over 50 different messaging platforms. We’re talking Discord, Slack, Telegram, WhatsApp—you name it. Its goal is to be everywhere, to give you an agent that can operate across every surface you use. It’s all about breadth. This makes a lot of sense, especially when you consider its founder, Peter Steinberger, joined OpenAI back in February, and OpenClaw is now run by an independent foundation with OpenAI as a sponsor.
Hermes Agent, on the other hand, is the quiet student in the back of the class who’s secretly brilliant. Instead of focusing on being everywhere, Hermes focuses on getting smarter. It’s built around a simple but powerful loop: do, learn, improve.
Here’s how it works: After Hermes completes a task for you, it doesn’t just forget about it. It enters a "reflective phase" where it literally analyzes its own performance. If it finds a good way to do something, it autonomously creates a reusable "skill file" so it can do it better and faster next time.
It’s designed for compounding value. The longer you use Hermes, the more it learns your specific workflows and the more efficient it becomes. It’s a bet on depth and intelligence over sheer presence.
The Blistering Pace of Hermes
One of the most impressive things about Hermes has been its relentless release schedule. The team at Nous Research has been shipping major updates at a dizzying pace since its launch in February 2026.
Let's just look at the last few weeks:
- The "Everywhere" Release (v0.9.0): This one pushed Hermes onto 16 different platforms, adding support for Android, iMessage (via BlueBubbles), and even WeChat.
- The "Interface" Release (v0.11.0): This was a monster update with over 1,500 commits. It brought a full user interface rewrite, native support for AWS Bedrock and NVIDIA NIM, and even access to GPT-5.5.
- The "Tenacity" Release (v0.13.0): Dropping on May 7th, this is the version that likely pushed it to the #1 spot. It introduced a Kanban-style board for managing multiple agents, a
/goalcommand to keep the agent focused on a long-term task, and a ton of security fixes. It also added Google Chat, bringing its total platform count to 20.
This isn't just a project with a few updates; it's a project with incredible momentum, backed by hundreds of contributors.
Let's Talk Security (The Elephant in the Room)
Okay, we have to talk about security. When you’re running an AI agent with access to your data and accounts, this is non-negotiable. And here, the two projects have very different track records.
OpenClaw’s massive scale has, unfortunately, come with some serious security headaches. In March 2026, there was a brutal four-day window where nine different CVEs (Common Vulnerabilities and Exposures) were disclosed. One of them, CVE-2026-25253, was a nasty remote exploitation bug with a CVSS score of 8.8. Another one from that batch scored a 9.9, which is about as critical as it gets. On top of that, security audits found hundreds of malicious skills in its community hub, ClawHub.
Hermes Agent is younger, so its record is shorter, but it's not spotless. A few CVEs popped up in late April 2026, with the most notable being a missing authentication issue in an older version (v0.8.0).
The key difference here seems to be the response. The latest "Tenacity" release for Hermes specifically addressed 8 high-priority security issues, enabling things like data redaction and stricter permissions by default. It shows a proactive stance that’s clearly resonating with developers.
Making the Switch or Using Both?
For developers currently running OpenClaw, the Hermes team has made the transition surprisingly painless.
If you’re thinking about trying it out, Hermes has a built-in migration tool. When you set it up, it detects your existing OpenClaw configuration and offers to import everything—your settings, memories, skills, and API keys. A simple hermes claw migrate command is all it takes.
But here’s an interesting trend we’re seeing: people aren’t always choosing one or the other. Some are running them in parallel. They use OpenClaw for what it’s best at—managing all the different chat platforms—and then hand off the actual thinking and task execution to a Hermes agent. It’s a "best of both worlds" approach that’s getting pretty popular.
So, Which One Should You Bet On?
At the end of the day, the right choice really depends on what you’re trying to build. This isn't about one being definitively "better" than the other; it's about picking the right tool for the job.
You might lean towards OpenClaw if:
- Your absolute top priority is being on as many messaging channels as possible (50+ is hard to beat).
- You want immediate access to a massive library of over 44,000 community-built skills.
- You’re building complex systems where multi-agent orchestration is the main challenge.
On the other hand, Hermes Agent is probably your best bet if:
- You want an agent that learns and gets better at your specific tasks over time.
- You’re working on long-term projects where memory and context are critical.
- You need flexibility with AI models (it supports over 200 via OpenRouter, plus AWS Bedrock, NVIDIA NIM, and local models).
- You’re building with a security-first mindset.
The shift in the OpenRouter rankings tells a fascinating story. It suggests that for a growing number of developers, an agent’s ability to learn and improve—its depth—is becoming more valuable than its ability to be everywhere at once. OpenClaw still has a massive user base and a huge head start in all-time usage, but right now, all eyes are on Hermes. The race is far from over, but for today, we have a new king.
