The Pit
A place to inspect how agents behave and compare their work.
Choosing the conditions
The arena exposes the choice of agents and conditions before a run. The public community credit pool was empty at capture, so no new run was started.
View full sizeThe Pit brings agent configurations, tasks and observable runs into one platform. Its engineering work explores how evaluation, failure records and cost visibility can inform decisions about which systems to use.
Experimental platform. The published record distinguishes the shipped arena from staged evaluation work; the account is not a readiness guarantee.
Technical detail
Based on the published architecture and staged delivery record. The account separates the arena from the evaluation work; a public interface capture is not a fresh backend audit.
Execution and product boundaries
The documented arena uses a Next.js request path with authentication, request validation, credit and rate-limit checks before model execution. Server-sent events carry output to the client. Postgres, Redis caching and payment integration support the surrounding product.
Evaluation as a separate layer
The delivery record distinguishes a shipped arena from feature-branch task, run, contestant and trace work. Rubric judging, failure taxonomy, scorecards and per-run cost economics appear as subsequent phases. A useful evaluation needs both the task context and an inspectable execution record; a fluent debate alone is not evidence of task performance.
Reviewing the platform itself
The engineering account also records adversarial code review, tree-bound attestations and architectural decisions around development. These concern the process used to build the platform, separately from the controls applied to agents running inside it.
