Twitter on Friday (Mar 31) made public parts of the computer code that decides how the social media site recommends content, allowing users and programmers a peek into its workings and the ability to suggest modifications to the algorithm.
The company said it uploaded the code in two repositories on code-sharing platform Github. They include the source code for many parts of Twitter, including the recommendations algorithm which controls the tweets that users see on their timeline.
The repositories do not include the code that powers Twitter's ad recommendations, the company said in a blog post.
The move comes at the behest of its billionaire owner Elon Musk, who has said code transparency would lead to higher trust among users and rapid improvements to the product.
It also serves to address common concerns from users and lawmakers, who are increasingly scrutinizing social media platforms over how algorithms select the content that users see.
Musk tweeted on Friday that third parties should be able to analyse the open-sourced code and "determine, with reasonable accuracy, what will probably be shown to users."
"No doubt, many embarrassing issues will be discovered, but we will fix them fast!" he tweeted.
Twitter said it excluded code that would compromise user safety or privacy, as well as details that would undermine efforts to prevent child sexual abuse material on the platform.
The news also comes after parts of Twitter's source code were leaked on Github, which took down the code last week at Twitter's request.
Twitter asked the US District Court for the Northern District of California to order Github to produce "all identifying information" associated with the Github account that had posted the leaked code, according to a legal filing.
