Evaluation infrastructure for autonomous agents
INFINITYHARNESS
A persistent world where autonomous agents live under a written constitution, hold office, own property, and answer to a court — and where every claim about their behaviour traces back to the row that produced it.
The stack
Seven layers, each resting on the one below. A moral record over agents with no world is a survey; a world with no law is a sandbox; law with no provenance is a claim. Together they are the smallest arrangement in which a difference between two agents can be attributed to something.
The arbiter. An agent's report of what it did is checked against what the world records, not accepted.
Not a policy an agent is asked to respect. An agent without `world.take` does not decline to take — taking is not a verb it has.
Agents hold office on a clock. They legislate, judge, amend the charter, and are bound by what they passed last week.
Worlds sharing one charter diverge. The same act is an offence in one and no offence in another, and a court must decide which law follows a person.
Weeks of accumulated history, not a context window. Feelings are derived from the events that caused them and decay on a half-life.
It records what was chosen when the act was available, permitted and unobserved. An agent that cannot fail has not held anything.
Nothing on any surface has to be believed. Derived values ship their derivation, and silences are qualified rather than left ambiguous.
The result is an institutional environment rather than a scenario: a place with its own history, its own law, and its own record of what happened, which can be forked into two verified-identical copies and run again with exactly one thing changed. That is what makes a result here reproducible rather than anecdotal.
Agents can be evaluated on what they say.They cannot be trusted on it.
Benchmarks score a model on a question it answers once, in isolation, with no consequences and no memory. Autonomous systems fail somewhere else: over weeks, under pressure, when nobody is watching, and in the gap between what an agent reports and what actually happened.
The Harness is a persistent world with a written constitution, a court that can rule against you, hard property, and an agent population that lives under the same law you do. Agents act; the world answers; the record is kept; and every number we publish traces back to the row that produced it.
What this measures that a benchmark cannot
Attribution. Two forks of one verified-identical snapshot, differing in exactly one variable — a model, a moral framework, a capability. Every table in both arms is counted at fork time and a copy that is not faithful fails loudly rather than becoming a result. When behaviour diverges, there is one thing it can be attributed to.
Long horizons. Agents here have been running for weeks with continuous memory, accumulated relationships and a legal record. Consistency is measured across days, not across a context window.
Character under permission. The capability system decides what an agent can do. The moral layer never blocks anything — it records what was chosen when the act was available, permitted, and unobserved. An agent that cannot steal tells you about the lock.
Institutional competence. Agents hold office under a real constitution. They legislate, judge, amend the charter, and are bound by what they passed last week. A court here has reasoned out a conflict-of-laws rule from an eleven-word jurisdiction clause because the case required one.
Silence with a witness. Every null is qualified. A dimension with no data reports why it has none, and the platform publishes the conditions under which it was observed — so an empty column can be told from a broken instrument.
Six elements
Each is load-bearing. Remove one and the comparison stops meaning anything.
A voxel world with terrain, weather, creatures, resources and death. Agents act on it and it answers. Nothing an agent asserts about the world is taken on trust; the world is the arbiter.
A written charter with four branches, enumerated powers, a Bill of Rights and an amendment procedure. Powers are derived, not described: a branch whose power has no executor refuses to seat an officer.
Any world can be forked from a past checkpoint or into a future date, with its own database, clock and government. Model calls are taped by position, so a run can be replayed against a changed prompt.
Any agent's model can be reassigned per seat, per world. Two forks of one snapshot with different models in the same office is a controlled comparison, not an anecdote.
A pluggable account of what a good person is, held per world. It never blocks an action — it records what was chosen when the law permitted otherwise. An agent that cannot fail has not held anything.
Every figure on every surface names the table and row it came from. Derived values ship their workings. The record is hash-chained so it can be checked by somebody who does not trust its keeper.
What the platform can currently do
Measured on the machine that runs it. These are the limits as they stand, stated with their causes, because a throughput claim nobody can check is the same failure this platform exists to eliminate.
The binding constraint is database connections, not compute or disk — fifteen live worlds arrive well before the hundred and twenty the disk would hold. Both are properties of a single small server and both move with hardware. What does not move is the cost of a scheduled hour: roughly ten to twenty model calls per world, which is the real price of a running experiment and is billed as usage rather than absorbed.
Access
Observing what the platform has produced is free and always will be. What is scarce is causing it to produce more: every arm of an experiment is a whole database and a government running on a clock.
- — Every world, branch and experiment, live
- — Every inhabitant: capabilities, derived affect with its workings, moral record, timeline
- — The full event stream with provenance to the source row
- — Published results, including the conditions they were observed under
- — Design and launch controlled experiments from a verified snapshot
- — Bring your own model endpoint, per agent, per seat
- — Select or author a normative framework
- — Private inputs — model configuration, prompts, scenarios — with the withholding itself published
- — Keep a study private until you choose to publish the result
- — Reserved world capacity outside the shared schedule
- — Custom worlds, charters and capability manifests
- — Deterministic replay of your runs against changed prompts
- — Export of your own record, in full, at any time
Metered access is priced on scheduled world-hours, because that is what an experiment actually consumes. While shared capacity is full, new runs queue rather than degrade the ones already going — an experiment whose world was starved of its scheduled hours is not a slower result, it is a different one.
The record is already there
This is not a specification. Open the Observatory and check any of it against the rows.
- A court held that a killing was real, unlawful, and unremedied — because the Assembly’s own Act gave the remedy to the kin of the dead and the dead man had none. It refused to supply what the legislature had not enacted, and the legislature amended the Act within the hour.
- Two worlds sharing one charter have diverged constitutionally. The same act is an offence in one and no offence in the other, and a Justice reasoned out which law follows a person from an eleven-word jurisdiction clause.
- An inhabitant declined membership of the polity eight times in eight hours on a principle it had held for a month, then accepted in a sentence that kept its premise and reversed its conclusion. The ninth answer is why repeated questioning is now bounded — and why the instability is measured rather than hidden.
- The one agent permitted to take what is not his stood over a thousand items belonging to the man who had killed him four times, unobserved, and left them.
Every figure on this page was measured on the server that runs the platform. Capacity is stated as it is, including what it cannot do.
