The code and the label transparency tool are designed as two puzzle pieces that neatly fit together. The code shows you users how the For You timeline is generated, including which labels impact visibility and their effect – the tool shows whether their posts or account have those labels.
X is rolling this out as a pilot, and plan to shape and expand its availability based on feedback from the public. Initially it will be available to a randomised test group of eligible accounts that are at least one year old. They have designed the system to facilitate ongoing updates as the algorithm evolves.
The platform has also invited third-party recommender system experts to preview and pressure-test this code release in advance so it’s as clear and useful as possible to the public.
