Hermes Agent: Introduction and Core Features
Last updated: 2026-08-31
Hermes Agent is like a personal assistant that learns — after every conversation it remembers you, teaches itself new skills, and understands you better each time.
📋 Prerequisites: Beginner-friendly, basic command line knowledge helpful

About Code Example Outputs
This course uses a deterministic/non-deterministic separation pattern for code examples, which is the industry best practice for AI Agent tool tutorials:
| Marker | Meaning | Your Output |
|---|---|---|
| Output: | Deterministic results (installation, configuration, counts, etc.) | Should closely match the example |
| Interaction Flow: | Agent behavior flow (LLM calls, tool selection, etc.) | Actual text will differ, but the flow will be similar |
| Verification: | How to check exercise results | Follow the described steps to verify |
1 + 1 = 2 (always the same). AI Agent tools: agent.chat("analyze code") = ??? (different every time). This is an essential characteristic of AI Agent tools, not a bug.
2. Story
(1) Pain Point: Starting Over Every Conversation
Bob uses ChatGPT for work every day, but each new session requires re-explaining project context, style preferences, and tech stack. He has tried writing System Prompts, but the model always "forgets" previous agreements.
(2) Solution: Agent Remembers Everything and Self-Learns
Alice deployed Hermes Agent and told it her tech stack and work habits during the first conversation. The next day, the Agent automatically recalled the correct context and even used /learn to create a "React Component Review" skill:
# Hermes automatically recalls previous conversations
> Help me review this component
Agent: [Recall] You prefer TypeScript + Tailwind, reviewed 3 components last time...
[Auto-invoke skill: react-component-review]
# You teach it a new skill, it remembers forever
/learn When reviewing components, always check: 1) type safety 2) accessibility 3) performance
→ Skill "react-component-review" created and saved
Bob was amazed: "This isn't a chatbot, it's a colleague that grows!"
3. What is Hermes Agent?
(1) Definition
Hermes Agent = LLM + Persistent Memory + Self-evolving Skills + Tool System + Multi-platform Access
| Component | Purpose | Analogy |
|---|---|---|
| LLM | Understanding, reasoning, decision-making | Brain |
| Persistent Memory | Remembering user preferences and context across sessions | Long-term notebook |
| Self-evolving Skills | Auto-creating and improving skills | Self-learning ability |
| Tool System | 70+ built-in tools for real operations | Hands |
| Multi-platform Access | Telegram/Discord/Slack etc. | Multiple communication channels |
(2) Chatbot vs Regular Agent vs Hermes Agent
| Dimension | Chatbot | Regular Agent | Hermes Agent |
|---|---|---|---|
| Memory | None/Session-level | Session-level | Cross-session persistent |
| Skill Learning | None | Manual coding | Auto-create and improve |
| Tool Count | 0-5 | 10-30 | 70+ |
| Platform Integration | 1 | 2-5 | 15+ |
| Privacy | Cloud processing | Depends on deployment | Local-first, zero telemetry |
| Model Support | Fixed | Limited | 200+ models |
4. Core Features in Detail
(1) Persistent Memory System
Hermes's memory is not simple conversation history — it is a three-layer architecture:
graph TD
A[User Input] --> B[Working Memory<br/>Current conversation context]
B --> C[Long-term Memory<br/>Cross-session preferences/knowledge]
C --> D[User Model<br/>Honcho deep profiling]
D --> E[Personalized Response]
| Layer | Content | Duration |
|---|---|---|
| Working Memory | Context and intent of current conversation | Single session |
| Long-term Memory | User preferences, project info, common patterns | Permanent |
| User Model | Honcho-modeled behavioral profile | Permanent + auto-updated |
(2) Self-evolving Skill System
Hermes acquires new skills through two methods:
# Method 1: /learn command, user-initiated teaching
/learn When I ask you to write Python code, always use type hints and docstrings
# Method 2: Auto-learning, Agent observes repeated patterns and creates skills
# Agent notices you always request a specific format...
# → Automatically creates "python-code-style" skill
(3) 70+ Built-in Tools
| Category | Tool Examples | Count |
|---|---|---|
| Filesystem | Read/write files, directory management, search | 10+ |
| Web | Browser, search, scraping | 8+ |
| Code Execution | Python, Shell, multi-language | 5+ |
| Vision | Image understanding, OCR, screenshots | 5+ |
| Voice | TTS, STT | 4+ |
| Data | Database, API calls | 10+ |
| Communication | Email, messaging, notifications | 8+ |
| System | Process management, cron tasks | 5+ |

6. Research-Ready Features
Hermes Agent also includes batch experiment features designed for AI researchers:
# Batch trajectory generation
from hermes import TrajectoryGenerator
generator = TrajectoryGenerator(
model="gpt-4o",
tasks="research_tasks.jsonl",
output_format="sharegpt"
)
trajectories = generator.run(batch_size=10)
# → Outputs standard ShareGPT format for training data
| Research Feature | Description |
|---|---|
| Batch Trajectory Generation | Run N tasks at once, collect complete Agent trajectories |
| ShareGPT Export | Standard format, directly usable as fine-tuning data |
| Checkpoint Recovery | Resume experiments from checkpoints after interruption |
| Custom Evaluation | Built-in evaluation framework for quantifying Agent performance |
