year-long-multi-agent-social-simulation-driven-single-4-bit-quantized-8b CLM-0657In a year-long multi-agent social simulation driven by a single 4-bit quantized 8B model on a 12 GB consumer GPU with five agents, the run can be carried to roughly 50-52 simulated weeks before the accumulated prompt hits the context limit, while about 10% of finalized activity records are left with at least one missing field.

Observed on
Five agents, one apartment world, Qwen3-8B-AWQ served by vLLM with a 24,576-token server context limit, three unseeded stochastic runs.

- Validated by: Only weakly: a 52-week memory-off run showed L2/L3 artifacts disappear (an implementation dependency, not a behavioral effect), and a single unseeded 10-week M vs M+T comparison showed 2.72x more records per agent-week and lower lexical duplication but a higher missing-field rate (7.75% vs 1.57%); the authors disclaim causal behavioral claims.. Measured over three independent stochastic runs (154 system-weeks, 770 agent-weeks, 13,084 activity records) with no fixed global seed, no matched 52-week baseline, and incomplete health ablations; [truncated]

- For LLM agents on long-horizon web penetration testing, holding the backbone model fixed and moving global state out of the context window onto a persistent graph of verified facts and fact-conditioned intent edges raises task success most on the hardest tasks, where success depends on facts obtained dozens of steps earlier (88.2% overall and 75.0% hard, vs 44.1% and 25.0% for the strongest shared-plain-text-memory baseline).Completing tasks that take many steps or many hours · reviewed by AI
- In multi-agent LLM systems where one agent starts with an erroneous shared belief, broadcasting every agent's full context at every step raises the rate of false assertions above doing no synchronization at all, because the error propagates to agents that were previously correct — and the harm appears only in tasks where one wrong fact cascades across semantically linked dimensions (destination to airport to weather), not where agent contexts are largely orthogonal.Stating false facts confidently · reviewed by AI
- For LLM agents on dependent multi-step tasks, success decays geometrically with the number of steps under a single per-step reliability parameter that rises with model scale but stays below 1, so long horizons eventually collapse even for the strongest deployed systems — and the decay tracks step count, not context length, since bounding the context window steepens the decay rather than easing it.Completing tasks that take many steps or many hours · reviewed by AI
- For image-borne injected instructions delivered to tool-using agents, completion rate understates exposure: agents act on the injected instruction about ten times more often than they complete the objective (12.8% attempted vs ~1% completed across 720 runs), and most failures stop at the planning step where the model read the payload and simply did not act on it rather than at any architectural barrier.Following instructions hidden in data · reviewed by AI
- In multi-agent LLM pipelines over reasoning and code tasks with a pool of 3B-32B open-weight backbones, conditioning each per-step routing decision on a learned filtered memory rather than the full accumulated trajectory leaves accuracy about the same while cutting inference cost by roughly 40-50%, so most of the accumulated history is cost without accuracy value.Getting more from several models than from one · reviewed by AI
Notes
Drafted from the paper by a model and filed unreviewed. Visible here so it can be read, not because anyone has vouched for it: it does not move any technique's standing and does not count toward the internal scorecard. Drafted confidence: medium. Falsifier as drafted: A comparable five-agent, 8B-quantized port that runs well past 52 weeks without hitting a context boundary, or that shows missing-field rates far from ~10%, under the same memory and context settings.
