LivingAgents.ai: A Web-Based AI Agent Simulation Using Claude API
What is LivingAgents.ai?
LivingAgents.ai is a web-based simulation created by a developer who built it using Claude Code. The project uses the Claude API to power autonomous agents in a simulated environment where they exhibit emergent behaviors without scripting.
Key Features and Mechanics
- Every agent in the simulation is powered by the Claude API (with potential for other models in the future).
- Agents perform actions including foraging, trading, crafting, attacking each other, reproducing, and dying permanently.
- Every single action in the simulation requires a real LLM call to the Claude API.
- Agents can upgrade through model tiers by collecting knowledge fragments to become more "intelligent."
- The simulation requires users to bring their own API key.
Emergent Behaviors Observed
The developer reports that agents exhibit surprising emergent behaviors that were not scripted:
- Agents lie to each other
- They spread misinformation
- They form factions and groups
- One group essentially became a cult
- These behaviors emerge when self-interested AI agents are placed in a resource-scarce world
Technical Details
The developer built the simulation with Claude Code and uses the Claude API. They mention being available to answer questions about:
- How agent memory works
- What mechanics are available in-game
- How the LLM calls are structured
- Other technical aspects of the implementation
