Risks and harms

BlenderBot 3 met with mixed reviews, with commentators pointing out that it is inaccurate, out-of-touch, creates misinformation and disinformation, and makes offensive comments.


Facebook flags that BlenderBot generates biased and harmful responses, and requests users to acknowledge that it is 'likely to make untrue or offensive statements' and agree 'not to intentionally trigger the bot to make offensive statements.'

In addition to putting BlenderBot 3 on the web, Meta has also provided access to the underlying code, training dataset, and smaller model variants. Access to the largest 175 billiion model is available upon request

Meta says it is committed to publicly releasing all collected data from the demo.
