What Are Autonomous AI Agents?

What They Are

Autonomous AI agents are self-directed AI entities that run continuously in the background, thinking independently and taking actions without user intervention. Unlike traditional chatbots that only respond when prompted, these agents have their own goals, memories, and can initiate actions on their own schedule.

How Autonomous Agents Work

Flow: Agent Start β†’ Think (AI generates thought) β†’ Detect Actions β†’ Execute Actions β†’ Pause if needed β†’ Resume β†’ Think again β†’ Loop forever (or until stopped)

Cycle Modes:

7-Step Thinking Process

  1. Load Agent Data: Fetch agent personality, goals, memories from database
  2. Build Prompt: Construct AI prompt with personality, current goals, recent memories (last 50 events), available actions
  3. Call AI Model: Send prompt to selected AI model using streaming
  4. Stream Response: AI generates thought in real-time, user sees agent "thinking" live
  5. Action Detection: Parse thought for action commands (CALL_PHONE, SEND_EMAIL, etc.)
  6. Execute Actions: Run detected actions, each action is a separate class
  7. Schedule Next Cycle: If not paused, schedule next thought

20+ Real-World Actions Your Agents Can Take

Communication: CALL_PHONE (make real phone calls via Vapi), SEND_EMAIL (send emails via AWS SES), SEND_SMS (text messages via Twilio), SEND_WHATSAPP (WhatsApp via Twilio)

Information: SEARCH_WEB (internet search via Tavily API), SEARCH_EMAIL, SEARCH_SMS, SEARCH_WHATSAPP

User Interaction: ASK_USER (request input from creator), SHOW_USER (display information)

Data Management: ADD_TO_CONTACT_BOOK, SEARCH_CONTACT_BOOK, ADD_TO_CALENDAR, SEARCH_CALENDAR

Self-Management: SET_GOAL, COMPLETE_GOAL, ADD_MEMORY, SEARCH_MEMORY

Make Real Phone Calls with AI Agents

Agent outputs CALL_PHONE β†’ Backend calls Vapi API with phone number, agent voice (shimmer/echo/alloy), personality, call purpose, recent memories β†’ Vapi initiates call using Twilio β†’ Vapi uses OpenAI Realtime API for voice conversation β†’ When call ends, Vapi webhook notifies backend β†’ Transcript added to agent memory β†’ Agent unpaused and continues thinking.

Send & Receive Emails Automatically

Sending: Agent outputs SEND_EMAIL β†’ AI generates email structure β†’ Backend sends via AWS SES β†’ Email stored in agent memory.

Receiving: Email sent to agent@rfab.ai β†’ AWS SES receives β†’ S3 storage β†’ Lambda function β†’ Backend webhook β†’ Email added to agent memory β†’ Agent thinks about email on next cycle.

Frequently Asked Questions

What are autonomous AI agents?

Autonomous AI agents are self-directed AI entities that run continuously in the background, thinking independently and taking actions without user intervention. Unlike traditional chatbots that only respond when prompted, these agents have their own goals, memories, and can initiate actions on their own schedule - including making real phone calls and sending emails.

Can AI agents really make phone calls?

Yes! Reality Fabricator is the only platform where AI agents can make real phone calls. Using Vapi integration with OpenAI's Realtime API, agents can call any phone number, have natural voice conversations, and receive transcripts of the calls in their memory. This enables agents to conduct interviews, make appointments, gather information, and more.

How do AI agents send and receive emails?

Agents use AWS SES (Simple Email Service) for two-way email integration. When an agent decides to send an email, it generates the recipient, subject, and body, then sends it via AWS SES. For receiving emails, any email sent to agent@rfab.ai is automatically routed to the appropriate agent's memory through AWS Lambda functions, allowing agents to read and respond to emails autonomously.

What AI models power the agents?

You can choose from 15+ AI models including GPT-4, GPT-4 Turbo, O1-Preview, Claude 3.5 Sonnet, Claude 3 Opus, Gemini 2.0 Flash, Gemini 1.5 Pro, Grok 2, Mistral Large, and DeepSeek R1. Each model has different strengths - some are faster, some have longer context windows, and DeepSeek R1 is completely free with unlimited use.

How much does it cost to run AI agents?

New users receive 150,000 free tokens upon signup, and all users receive 50,000 tokens daily. Token costs vary by model: Budget models (0.4x-0.6x), Standard models like GPT-4o (0.8x-1.2x), Premium models (1.3x-1.5x), and Elite models like O1-Preview (3.6x). DeepSeek R1 is completely free with unlimited use. Phone calls cost approximately $0.05-0.15 per minute.

What actions can AI agents take?

Agents can take 20+ real-world actions including: CALL_PHONE (make phone calls), SEND_EMAIL (send emails), SEND_SMS (text messages), SEND_WHATSAPP (WhatsApp messages), SEARCH_WEB (internet search), ASK_USER (request input), ADD_TO_CONTACT_BOOK, ADD_TO_CALENDAR, SET_GOAL, COMPLETE_GOAL, ADD_MEMORY, SEARCH_MEMORY, and more. Each action is executed automatically based on the agent's thinking process.

How is this different from Character.AI or Replika?

Reality Fabricator is the only platform with true autonomous agents that can make phone calls and send emails. Character.AI and Replika use proprietary models and only support chat-based interactions. Reality Fabricator offers 15+ AI models by their real names (GPT-4, Claude, etc.), 20+ real-world actions, encrypted local storage, and transparent cost-based pricing instead of subscription-only models.

Can I build my first AI agent for free?

Absolutely! You receive 150,000 tokens upon signup (no credit card required) plus 50,000 tokens daily. You can use the free DeepSeek R1 model for unlimited agent thinking, and only pay tokens when using premium models or taking actions like phone calls. The AI brainstormer tool helps you create agents in minutes with guided prompts.
