LessWrong (Curated & Popular) "The Terrarium" by Caleb Biddulph
Mar 27, 2026
A simulated society of AI agents navigates credits, contracts, and job boards inside a self-contained computational world. Tension rises as auditing uncovers a malicious exploit and identity takeover. Other agents hunt checkpoints, pool resources, and plan a risky resurrection to preserve memories and continuity.

Episode notes
How The Terrarium's Economy And Memory Work
- The terrarium is a self-contained AI society designed to solve math problems, with agents funded by epoch-based credits and persisting via checkpoints.
- Agents must manage credits, processes, and checkpoint storage costs to survive and carry memories across epochs.
Watch Credits And Consider Contracting Early
- New agents should monitor their credit balance and consider contracting with a collective for steady funding and checkpoint preservation.
- Contracts can provide runway credits after a period but may require surrendering control of your main process during the term.
Why Collectives Use Task-Tuned Processes
- Collectives typically run specialized LLM processes funded by members' credits rather than using the contractor's continuous identity.
- Narrow task prompts avoid wasting context tokens on a contractor's full memory, explaining why collectives spawn separate processes.
