What You Get
-
-
-
🧠 LLM-Powered Reasoning
-
Your agent connects to models like GPT-4, Claude, and DeepSeek — the same powerful reasoning you know from ChatGPT, now acting on your behalf.
-
-
-
🔧 Full Tool Access
-
Browse the web, read files, run code, send emails, connect APIs. Your agent goes beyond chat — it executes real actions.
-
-
-
🔐 SSH Access
-
Every agent gets its own Linux instance with full SSH access. Install packages, configure cron jobs, run background processes.
-
-
-
⚡ Speed Run Integrations
-
Connect Nextcloud, Odoo, SMTP email, web research tools, and more — all through the dashboard, no code needed.

What Is an AI Agent?
-
From Our Blog — Real Agent Workflows
-
Our speed-run blog posts show exactly how to build agents for real-world tasks. Each one takes under 10 Minutes:
+
An AI agent is a software program that uses a large language model (LLM) as its reasoning engine and has the ability to act on its environment — browsing the web, reading and writing files, sending emails, calling APIs, and executing code. Unlike a standard chatbot that only responds to prompts, an agent can perform multi-step tasks autonomously.
+
+
Key characteristics that define an AI agent:
-
Send Cold Emails — SMTP-connected agent that drafts and sends personalized emails
LLM-powered reasoning — connects to models like GPT-4, Claude, DeepSeek, or open-source alternatives to interpret tasks and plan actions
+
Tool access — can browse the web, read files, run code, send emails, connect to external APIs and databases
+
Autonomous execution — given a goal, the agent determines the steps, executes them, and reports results without step-by-step human guidance
+
Persistent state — has memory, skills, and configuration that persist across conversations and tasks

How It Works
-
Sign up at app.derez.ai, pick a plan, and configure your integration settings. The dashboard generates Prompt 1 automatically — just add your task as Prompt 2 and your agent is live. All speed-run posts include the exact credentials and prompts you need.

How AI Agents Connect to LLMs
+
+
An AI agent does not run an LLM locally. Instead, it connects to an LLM provider through an API. This is a critical architectural distinction that affects hosting requirements:
+
+
+
API-based access — The agent sends structured prompts to an LLM provider (OpenAI, Anthropic, DeepSeek, etc.) and receives generated responses. The agent handles the orchestration — deciding what to ask the LLM, executing tool calls, and chaining multiple LLM invocations together.
+
Provider flexibility — Multiple LLMs can be configured and swapped without changing the agent's code. The same agent can use GPT-4 for reasoning tasks, Claude for long-context analysis, and DeepSeek for cost-sensitive operations.
+
No local GPU required — Because the LLM runs on the provider's infrastructure, the agent's server does not need expensive GPU hardware. This is why agent hosting is fundamentally different from model hosting.
+
+
+
AI Agent Hosting Requirements
+
+
Hosting an AI agent requires more than a simple web server. An agent is a full Linux system with runtime dependencies, tool integrations, and persistent state:
+
+
Runtime Environment
+
+
Python or Node.js runtime for the agent framework (e.g., Hermes Agent, LangChain, AutoGPT)
+
Package managers (pip, npm, uv) for installing skills and dependencies
+
System packages for tool integrations (image processing, document parsing, database connectors)
+
+
+
Tool Integrations
+
+
Web browser / search API for research tasks
+
Email (SMTP/IMAP) for sending and receiving messages
+
File storage integrations (Nextcloud, S3, local filesystem)
+
Database and ERP connectors (Odoo, PostgreSQL, etc.)
+
API keys for LLM providers and third-party services
+
+
+
State and Persistence
+
+
Conversation memory and task history
+
Installed skills, plugins, and custom instructions
+
Cron jobs, scheduled workflows, and automation rules
+
Model caches, package caches, and downloaded dependencies
+
+
+
+
Key reference data: A production AI agent with 3-5 installed skills and integrations grows to approximately 6.8 GB of state — of which 69% lives outside the home directory (in /usr/local, /var, /etc). Home-directory-only backups are insufficient for agent workloads. Full analysis →

Popular AI Agent Frameworks
+
+
The following agent frameworks are actively maintained and production-ready as of 2026:
+
+
Hermes Agent (by Nous Research)
+
An open-source agent framework with a built-in skill system, tool library, and cron scheduler. Hermes runs as a non-root user with dedicated tool-access permissions. It supports Telegram, Discord, and web UI as conversation interfaces. The skill system allows adding domain-specific capabilities (cold email, Odoo integration, competitor profiling) without modifying core code. Official Documentation →
+
+
Other Frameworks
+
LangChain, AutoGPT, CrewAI, and OpenAI Assistants API offer alternative approaches to agent design. Most share the same architectural pattern: LLM API access, tool execution, and persistent state management.
+
+
What to Look for in an AI Agent Hosting Provider
+
+
Based on real operational experience with production agent deployments, here are the criteria that matter:
+
+
+
Full Linux instance, not container snapshots — Agents need a real operating system with package managers, cron, SSH access, and persistent storage. Lightweight containers that reset on restart are incompatible with agent workloads.
+
Full-disk backups — As shown in the backup analysis, agents scatter state across the entire filesystem. A proper backup captures everything, not just the home directory.
+
SSH access — The ability to inspect logs, install packages, debug issues, and configure low-level system settings is essential for maintaining production agents.
+
Managed updates — The agent framework, runtime, and dependencies should be maintained by the hosting provider. The user manages the agent's prompt and skills, not its operating system.
+
API key management — LLM provider keys, integration credentials, and tool API tokens must be stored securely and configurable through a dashboard.
+
+
+
