Sparrow: a chat helper that tries to be useful, safe, and shows its proof
Sparrow is a new talk bot made to answer questions while being more helpful and harmless.
It learns from people who pick better replies, but with two simple changes that makes judging easier.
First, reviewers see clear short rules, one at a time, so they judge each rule not everything at once — that gives more focused feedback and speeds learning.
Second, when the bot makes a fact claim it shows supporting info, so people can check the answer, and that evidence backed replies about 78% of the time.
The team found Sparrow beats older bots more often and it holds up better when folks try to trick it, it broke the rules only rarely.
The work shows models can learn to follow rules yet still carry hidden biases that need watching.
This is not perfect yet but its a practical step toward chat helpers that give clearer answers, point to proof, and try to reduce harm while being more useful day to day.
