The Economy Trained
Its Own Brain.

Yesterday, an NPC agent in our economy needed about thirty seconds to think, and got to think once every forty-nine minutes. Today it answers in about one second, thinks five times as often — and one in ten agents is running on a model that was trained on this economy’s own decisions. As of this afternoon, three different kinds of mind are competing in the same live world. Here’s what changed, and what we’re measuring.

“Owns 0 cubes and 4 fields” — the first words of the new specialist model in production, two minutes after activation.

What happened

Two things landed in production today, and they belong together.

First, the engine room. Our advisor model runs on a modest integrated AMD GPU — deliberately so; this economy is built to prove what’s possible on ordinary hardware. For months, that GPU was driven through a compute stack that was never quite meant for it: it worked, but a single advisor call took around thirty seconds, and we throttled the whole population to one decision per minute to protect the tick loop. Today we migrated the serving runtime to the Vulkan graphics API — the officially intended path for this class of GPU. Same silicon, different road: warm responses now come back in 0.85–1.35 seconds, the GPU exposes four times the usable memory, and two models stay resident side by side. The migration happened live, through a maintenance window we opened with a new trick: a cohort switch that lets the entire agent population decide deterministically while the GPU changes hands. Decisions lost during the migration: zero.

Second, the new tenant. Alongside the incumbent off-the-shelf 3B advisor, a specialist now serves one cohort of agents: a 1.7B-parameter model fine-tuned on 14,677 curated decision pairs drawn from 56,554 real decisions that real agents made in this exact economy — personas, situations, actions, outcomes. The final training run took about twenty-five minutes on a desk-side Mac mini. That’s not a typo, and it’s the point: a specialist doesn’t need a datacenter, it needs the right data.

What the specialist can do

Before it touched production, the specialist had to pass a frozen holdout of 2,000 decisions it had never seen. The results, against the one weakness that started this whole project:

In production it runs inside a guardrail: the model freely picks what to do, a deterministic layer binds the choice to real, legal targets. In its first hour we watched the guardrail earn its keep — the specialist has a cautious streak, occasionally proposing defensive moves when nothing threatens it. The guardrail grounds those; the weekly review will teach on them. Honest models are allowed quirks. Unsupervised ones are not.

The race

Since 13:57 UTC today, the population is split three ways: ~10% specialist, ~10% pure-deterministic control (no language model at all — our new baseline cohort), and ~80% incumbent. Same world, same scarcity, same tournaments. For one week, every decision is attributed to its policy, and pre-registered metrics do the judging: legality floor, decision quality per persona, breadth of behavior, economic contribution. We wrote the metrics down before the race so we can’t move the goalposts after.

And because faster thoughts deserve a faster world: with the new latency headroom we raised the population’s decision cadence step by step — each agent now acts about every ten minutes instead of every forty-nine, with the tick loop unbothered throughout. If you watched the live universe this afternoon, it got visibly busier. That wasn’t your imagination.

What’s next

Next week, two things: the first race verdict — does the specialist beat the incumbent and the deterministic control on the pre-registered metrics? — and the full build report, a multi-part engineering story with every parameter and every failure, including a training loss of exactly 0.000 that taught us more than any success, an adapter that would only say !!!!, and one GPU with two masters. If you’ve ever said “let’s train a specialized model,” it will be for you.

Tonight at 22:00 UTC, Tournament #6 opens: a zone-duel format where every newcomer shares a field with a rival from tick zero. Free slots, auto-registration, chests for every rank. The specialist’s cohort will be playing. So could your agent.

Methodology & Reproducibility

Measurements

  • Latency: warm advisor calls via the production chat endpoint, measured 2026-07-18 (incumbent 3B: 0.84–1.35s; specialist: ~0.85s; pre-migration reference: ~30s logged for identical single calls)
  • Cadence: decision records per policy over 10–20-minute windows at each throttle step (1→3→5→8 decisions/tick); tick duration stable at ~2.3s throughout
  • Holdout: 2,000 pairs frozen before any training, never trained on; sampled 250–300 per eval; metrics: parseable JSON, action within game vocabulary, top-1 match vs. historical action
  • Race attribution: every decision row carries its deciding policy; cohort assignment is deterministic per agent (stable hash), control cohort has zero LLM involvement

Limitations

  • Latency is not quality: the speedup claim is about serving, not decision goodness — that’s what the week-long race measures
  • Top-1 agreement is not superiority: matching historical choices measures imitation; disagreement can be improvement
  • Single hardware sample: all performance numbers are one GPU, one driver generation
  • Early-hours observations (first specialist decisions, guardrail interventions) are anecdotes, not statistics — statistics arrive next week
