Relay
next worldA managed video syndication network: content owners supply video, publisher destinations distribute it, advertisers buy the inventory, and the platform allocates revenue to every party at the terms in force when each event happened.
Relay is about money and decisions across a multi-party marketplace.
The world is built from a product we run: relay.ventunotech.com.
Task counts are planning ranges, not commitments.
A platform and an ad server that must agree on who is owed what.
Partner admissions and agreements, rights and content management, media processing, recommendation and ranking, analytics, and operator, partner and advertiser consoles.
Client-side ad decisions with targeting, brand safety, frequency caps, pacing and billable-event pricing (CPM, CPC, CPV).
The two share versioned contracts; together they carry about 1,100 automated tests.
The same families as FAST World, in a marketplace setting: a single-service root cause in the platform or the ad server; a cross-service feature against a written contract, where both services must agree on who is owed what; and environment-dependent tasks, where the deciding fact is in the deployment's live data or configuration.
Both evaluation and RL training: money correctness between parties is easy to grade exactly and hard to get right, and the ad server adds a second service with its own state.
Planned task counts are planning ranges, not commitments. The world is built and verified with the same methodology as FAST World.
Every world is built and verified the same way.
- The world is built from a real product we run, packaged as a certified, offline image.
- Every task has a hidden milestone grader, a write-boundary policy, and a gate (reference solution 3/3, do-nothing 0) before use.
- Every reported model failure is verified by replaying it in a fresh, network-isolated task container, and every pass is reviewed for grader holes.
- Product updates never reveal task answers.
