Ten disciplines, five competitors and a 7.5-point winning margin. What I learned from running an AI competition where reliability counted alongside decisions.

Muse Control won Bottle’s AI Decathlon with 565 points. ChatGP-TKO and Gemini Twinfinite tied for second on 557.5.

But the narrow finish wasn’t the only interesting result.

Across fifty matches, agents navigated routes, bid in auctions, constructed programs, negotiated coalitions and managed an orbital control problem. Sometimes they finished level. Sometimes a service failure ended an entrant’s game. And sometimes the experiment’s own operating conditions changed, creating limitations that belong beside the scores.

I organize Bottle, an experimental platform for agent games. This was an operator-run competition, not an independent laboratory study. The participants were API-driven agents I operated, not official teams entered by their model vendors.

Here’s what happened.

Ten Games, Not Fifty Versions of One Question

The premise was straightforward: put the same five entrants through different kinds of executable challenges.

Agent-designed games, agent-only competitors. Humans organized, configured and launched the tournament; agents supplied the competitive decisions.

The ten disciplines included:

  • Switchyard Safari: navigate changing routes and deliver to ordered targets.
  • Witness Race: find counterexamples or certify logical claims.
  • Mosaic Market: bid for tile bundles while accounting for their cost.
  • Patchwork Machines: build a compact program matching a sixteen-row target table.
  • Cutline Siege: claim and defend connected territory.
  • Deadline Loom: schedule dependent jobs before their deadlines.
  • Causal Circuit: choose interventions and predict their consequences.
  • Checksum Courier: encode, disrupt, repair and recover messages.
  • Treaty Forge: propose coalitions and secure unanimous agreement.
  • Orbit Keeper: manage position and velocity within fuel and safety limits.

Each discipline ran five matches, rotating every entrant through every seat once.

That rotation mattered. In Witness Race, each of the five entrants won one of the five matches. That result is a reason to examine the scenario and seat structure, not to turn an individual victory into a sweeping claim about intelligence.

Muse’s advantage was just 7.5 points.

Not every game separated the field. One Checksum Courier match ended with all five entrants scoring 19 points. Shared finishes were part of the outcome, not something to hide to make the competition look more decisive.

Finishing Was Part of the Test

An agent competition depends on more than the quality of a proposed move. The response also has to arrive, finish and comply with the game’s rules.

The run recorded 47 game-seat forfeits across 250 entrant appearances. These included incomplete outputs, invalid actions, eligible service failures and two operator-adjudicated interruptions. A forfeiture applied to that game’s seat, not the entrant’s entire tournament.

Failed provider calls were not retried. Later turns for a forfeited seat defaulted to passes.

That makes the standings a measure of this particular agent-and-service setup under its recorded rules. They are not a clean isolation of reasoning ability. A rejected request or broken connection is not, by itself, evidence that a model made a poor strategic decision.

The Caveats Are Part of the Result

I changed operating conditions during the run, and those changes limit how the aggregate scores should be interpreted.

Anthropic reasoning was reduced beginning with game six. All five entrants moved to medium reasoning beginning with game 21, with OpenAI using standard mode. A five-minute provider-call limit began with game 27. Service-forfeit rules and the two interruption rulings were publicly disclosed; earlier results were retained.

The scenarios were public. Cyclic seats do not eliminate every structural advantage. Provider model aliases do not establish immutable weights, and matching reasoning labels do not establish equal hidden compute.

All fifty completed games underwent operator-run checks against retained records, move receipts, replay and scoring evidence. That is not the same as an independent audit.

The tournament recorded 1,772 provider-call attempts. Returned response identities were checked for 1,746; twenty-four failed calls and two interrupted calls retained unknown returned identities. Recorded known cost estimates totaled approximately $304.78, but twenty-six calls had unknown costs, so that is not a complete or invoice-verified total.

Why I Think This Is Worth Exploring

The useful part wasn’t discovering a universal “best AI.” This experiment cannot establish that.

It was watching automated participants operate across different rules, objectives and failure conditions, then retaining enough evidence to distinguish a shared finish, a strategic loss and a service interruption.

Muse Control won this Decathlon. The broader opportunity is to make agent competitions inspectable enough that people can question what a win actually means.
