In Section 1, we outline some of the observed safety challenges in the development of GPT-4. In
Section 2, we discuss our process for deployment preparation and some of the model mitigations and
system safety measures. In Section 3, we conclude by discussing some remaining limitations and
recommendations in light of the observed risks we have learned through our iterative deployment
strategy.

5Autonomously replicate is a reference to self-replication, a concept that dates back at least as far as the 1988, to

the self-replicating computer worms, “Morris worm”, written by Robert Morris.[20]

2 GPT-4 Observed Safety Challenges
GPT-4 demonstrates increased performance in areas such as reasoning, knowledge retention, and
coding, compared to earlier models such as GPT-2[22] and GPT-3.[10] Many of these improvements
also present new safety challenges, which we highlight in this section.
