Artemis City vs Auto-GPT: An Honest Comparison

Helping you choose the right tool for your use case

Executive Summary

Auto-GPT is an impressive demo of autonomous agent loops. It showed the world what's possible with LLM-driven task execution.

Artemis City is a production-ready operating system for multi-agent orchestration with kernel-level governance.

Both are valid—but for different purposes.

Detailed Breakdown

1. Architecture Philosophy

Auto-GPT:

Goal → LLM → Action → LLM → Action → ...
  • LLM decides everything
  • Autonomous loop until goal "achieved"
  • Human in the loop via approval prompts

Artemis City:

User Request → Kernel Routes → Agent Executes → Kernel Logs → Memory Persists
  • Kernel decides routing
  • Deterministic execution flow
  • LLMs are compute resources, not orchestrators

When to choose Auto-GPT: You want to see what an LLM can do when given autonomy

When to choose Artemis City: You need predictable, repeatable workflows

2. Routing & Task Planning

Auto-GPT:

# Simplified example
while not goal_achieved:
    next_action = llm.decide_next_action(goal, memory)
    result = execute(next_action)
    memory.append(result)
    goal_achieved = [llm.is](<http://llm.is>)_goal_achieved(goal, memory)

Pros:

  • Flexible: LLM can adapt to unexpected situations
  • Creative: Finds novel solution paths

Cons:

  • Non-deterministic: Same goal → different workflows
  • Expensive: LLM call for every decision
  • Runaway loops: May never terminate

Artemis City:

# agent_router.yaml
routes:
  - pattern: "research|find|investigate"
    agent: researcher
    tools: [web_search, documentation]

  - pattern: "build|create|implement"
    agent: coder
    tools: [filesystem, shell]

Pros:

  • Deterministic: Same pattern → same agent
  • Testable: Unit test routing logic
  • Fast: No LLM call for routing decisions
  • Version-controlled: Routing is code

Cons:

  • Requires upfront design: Define routes explicitly
  • Less "autonomous": Human defines the workflows

When to choose Auto-GPT: Exploring unknown problem spaces

When to choose Artemis City: Building repeatable workflows

3. Memory & State Management

Auto-GPT:

  • Short-term memory: Recent actions in context window
  • Long-term memory: Vector embeddings in Pinecone/Weaviate
  • Persistence: Session-based, starts fresh each run
  • Format: Unstructured embeddings

Example:

Session 1: Agent researches Python best practices
Session 2: Agent has no memory of Session 1

Artemis City:

  • Structured memory: Postgres/Supabase (queryable via SQL)
  • Unstructured memory: Obsidian markdown (human-readable)
  • Persistence: Cross-session, with trust-decay metadata
  • User-owned: Lives in your Obsidian vault + Supabase instance

Example:

# Session 1
codex run "Research Python best practices"

# Session 2 (weeks later)
codex run "Implement a Python project"
# Kernel loads relevant memories from Session 1
# Trust score: 0.85 (slight decay over time)

When to choose Auto-GPT: Single-session tasks

When to choose Artemis City: Long-term projects requiring memory

4. Multi-Agent Support

Auto-GPT:

  • Single agent per instance
  • Can spawn sub-agents, but no orchestration layer
  • No built-in coordination between agents

Artemis City:

  • Native multi-agent orchestration
  • Kernel routes sub-tasks to specialized agents
  • Agents can reference each other's output

Example workflow:

codex run "Design and build a REST API"

# Kernel routes:
# 1. "Design" → planner agent (creates architecture)
# 2. "Build" → coder agent (implements using planner's output)
# 3. Both outputs linked in memory

When to choose Auto-GPT: Single-agent tasks

When to choose Artemis City: Complex workflows requiring specialization

5. Governance & Safety

Auto-GPT:

Safety mechanisms:

  • Human approval prompts for dangerous actions
  • Optional Docker sandbox

Governance:

  • No audit logs
  • No permission system
  • No cost tracking

Security model:

  • Trust the LLM to make safe decisions
  • Human intervenes when prompted

Artemis City:

Safety mechanisms:

  • Kernel-enforced tool permissions (RBAC)
  • Audit trail for all agent actions
  • Rate limiting and cost budgets
  • Trust-decay for stale memory

Governance:

tool_permissions:
  researcher:
    - web_search      # ✅ Allowed
    - filesystem_read # ✅ Allowed
    - filesystem_write # ❌ Denied
    - shell_execute   # ❌ Denied

Audit log:

{
  "timestamp": "2025-12-05T14:30:00Z",
  "agent": "coder",
  "action": "filesystem_write",
  "path": "/src/[api.py](<http://api.py>)",
  "outcome": "success"
}

When to choose Auto-GPT: Controlled environments with human oversight

When to choose Artemis City: Production environments requiring compliance

6. Cost Management

Auto-GPT:

Cost structure:

  • LLM call for every decision
  • Can spiral into expensive loops
  • Manual monitoring required

Real example:

Task: "Research machine learning papers"
Result: 437 web searches, 89 GPT-4 calls
Cost: $43.50
Useful output: 2 paragraphs

Artemis City:

Cost structure:

  • LLM call only for agent execution (not routing)
  • Kernel rate limits prevent runaway loops
  • Built-in cost tracking

Example:

codex run "Research machine learning papers" --budget 5.00

# Kernel enforces:
# - Max 10 web searches
# - Max 5 LLM calls
# - Stops at $5 budget

When to choose Auto-GPT: Exploration with unlimited budget

When to choose Artemis City: Production with cost constraints
