What changed
Each row is quoted from the source. Figures we could not find on the page in those words are marked — they are kept, not deleted, so you can judge them.
200,000Lines of code written
“said it has now helped write 200,000 lines of code.”
Quoted word for word from the source
100,000Lines of code createdfirst four months

Tedious, repetitive, and time-consuming work automated
“it had automated around 12% of the tedious, repetitive and time-consuming work done by an initial group of volunteers.”
Quoted word for word from the source
37Code suggestion acceptance rate

Quoted word for word from the source
15-20Code suggestions per active user per dayas of February (per BT's initial report)
“it was providing 15-20 suggestions of code per active user per day”
Quoted word for word from the source
“We absolutely could not get here if we did not see positive outcomes. It cannot get to that number without positive word of mouth.”
Difficulties and limits
- BT’s developer trainees don’t get access to the Amazon Q tool until they have learned the basic principles, because they need to learn their coding foundations to understand whether the recommendations coming from the tool are right or not.
- BT is also protected from the risk of GenAI hallucination because the coding is not automated – instead, the developer has to accept the code recommendations made by the tool, which should stop bad suggestions getting very far.
