[/et_pb_toggle][et_pb_toggle title=”What is Sigma’s pricing model?” _builder_version=”4.14.8″ _module_preset=”default” global_colors_info=”{}”]

We use two pricing models: hourly based and unit based. The model is driven by client preferences and type of data annotation.

[/et_pb_toggle][et_pb_toggle title=”How does the quantity of data and task quantity impact cost?” _builder_version=”4.14.8″ _module_preset=”default” custom_margin=”||24px|||” global_colors_info=”{}”]

The larger the volume of data the lower the cost. There are fixed costs that are common to all projects. If the quantity of data is large, then the impact of the fixed cost is lower and the cost per hour of work or per unit is lower too. If the volume of data is large, the labelers, the QA team, the project managers and other related personnel have time to reach the production peak and to maintain it.

The number of tasks reduces costs because larger quantities of data reduce some fixed costs, allows us to reuse workflows and experience in the type of data, simplifies communication with clients, and allows us to optimize the performance and quality of labelers through different strategies such as balancing their cognitive load.
