Start with the training decision
A useful brief begins with what the model must predict, control, or evaluate. From there, the program defines environments, observations, action semantics, state, outcomes, timing, coverage, and acceptance checks.
This keeps volume subordinate to utility. Hours and episodes matter only after the target transitions, edge cases, and evaluation split are clear.
- Original collection against a buyer specification
- Licensed or partner-supplied datasets where authority is confirmed
- Transformation, annotation, packaging, and quality review
- Evaluation sets designed around the intended model behavior
Supply routes stay visibly distinct
Original collection, partner-supplied data, and open research references are different products. Each route needs its own source record, rights evidence, restrictions, and delivery terms.
ActionTrajectories has an affiliate relationship with Yield Guild Games and can sell YGG-supplied datasets. Specific inventory and permitted uses are confirmed in the applicable commercial proposal, not inferred from the relationship alone.
The proposal is the availability record
A public page is an invitation to scope a program. It is not an inventory guarantee, fixed price, license grant, service level, or promise that a named source is available in every territory or for every use.
The written proposal confirms the dataset, source, scale, fields, quality checks, permitted uses, territories, redistribution position, delivery, price, and any dependencies. The final agreement governs supply.
